The phrase was also used to refer to calculators in the latter part of the 19th century. The term is typically used to designate electrically powered, programmable digital gadgets.

Using devices for calculating has been a part of human evolution since the dawn of time. In ancient times, the abacus was a popular tool. Charles Babbage, the inventor of computers, in 1822, then developed the first mechanical computer. Finally, he created an analytical engine, a general-purpose computer, in 1833. It had an ALU, some fundamentals of flowcharts, and the idea of integrated memory.

First Electrical Computer | The first electrical computer for general use arrived more than a century later in computer history. It was the Electronic Numerical Integrator and Computer, or ENIAC. J.Presper Eckert and John W. Mauchly created this computer.

Essay on Computer

Long and Short Computer Essay

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers.

In this essay, we will discuss the various components and types of computers and talk about their uses in various fields.

Long Computer Essay in English

A computer is an electronic tool that manipulates data or information. It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them.

Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations.

Common Components of Computers

All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory (RAM), motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices.

There are five main hardware components:

Input Devices:

These are devices that are used to enter data/information in the central processing unit. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc.

Output Devices:

These are devices that provide the processed data/information into human-readable form. Example- monitor, printer, speaker, projector etc.

Control Unit:

The control unit handles the various components of the computer; it reads and interprets (decodes) the instructions for the program, transforming them into control signals that activate other computer parts.

Arithmetic Logic Unit:

It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc., and square roots.

Central Processing Unit:

The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application.

Software refers to computer parts, such as programs, data, protocols, etc., that do not have a material form. In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions.

It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer.

Computer hardware and software require each other, and neither of them can be realistically used on their own. There are four main components of a general-purpose computer: the arithmetic logic unit (ALU), the control unit, the memory, and the I/O (collectively called input and output) devices.

Uses of Computer

Computer is one such man made device without which the mankind cannot imagine their existence. In short, a computer is a device that processes and stores information entered as the input and displays the information as the required output as and when the user desires.

Very huge in size and limited in functionality, the earlier computer was as big as an entire room and they consumed more power. It was in the year 1837 when Charles Babbage despite his limited resources and finances came up with a programmed version of the computer. Later, his son Henry Babbage modified the computer into a simpler unit. Initially, the use of computer was limited. They were merely used for calculations and not for carrying out tasks.

There was an important role played by computer in The World War II. War planning required huge calculations and with the aid of a computer, the armies found it easy.

A Luxury or Necessity:

There was a time when people considered the computer as a luxury but today it is a necessity. People cannot imagine their life without a computer. Well, it isn’t just a calculating device anymore. Modern computer carries out almost every task that the human desires. A computer nowadays is designed to store information and perform innumerable tasks as and when the user wants.

The information entered by the user is transmitted to the computer in the form of a programming language which is again transmitted into human language and the result is displayed.

Well, with computer becoming the backbone of almost every industry running today, you can very well judge whether it is a luxury or a necessity. It hasn’t just simplified tasks and made them quicker but computer has given birth to many other amazing inventions.

It is literally impossible to list the uses of a computer because the list is exhaustive. Basically, a computer nowadays performs innumerable tasks and it is required in every field. Thus, computer has been made a compulsory subject in primary schools almost everywhere. It has become an indispensable need for mankind and we cannot go a day without a computer. Available in varied designs and sizes, the modern day computer has also been modified into a portable form called a laptop. You can carry it wherever you go.

Be it offices, shops, schools, homes, and almost every other place; people cannot imagine their life without a computer. It is one such invention that has made human life super easy.

Well, just like everything has its share of advantage and disadvantages the same goes for computer.

The increasing rate in cybercrime is the biggest disadvantage that comes with computer. But if apt preventive measures are taken then maybe we can remedy the situation. Owing to the advantages computer has to offer we can overlook the few disadvantages it has.

The fast moving life that people are living nowadays is only possible because of this wonderful invention. With the passage of time, there has been an unbelievable advancement in the field of computer and the world has been constantly changing since then.

Owing to the rapid pace with which the computer industry has progressed, it can be rightly said that the coming days will be brighter, smarter and technically more advanced because we are sure to come up with even better computer systems. The next generations are sure to live an advanced life because with computer becoming better there’s no looking back.

Electronic devices on a whole might be making us lazy but we cannot deny the fact that computer is not just any ordinary electronic device; it is a boon to the human race.

Computers have been around in various forms for the past two centuries. Over that relatively short period of time this machine, or tool, has transformed mankind equally as much as fire or the wheel. That being said sometimes we take this device for granted and do not appreciate all the different things it is giving us.

When you stop and think about all the places where you can find a computer you will realize that almost all human endeavors in the present have some form of computerized help. Without this help, people wouldn’t be able to do their jobs as efficiently as they do now so let’s take a deeper look at the development of this amazing tool.

People have made many different tools all through history that they used to help them calculate and keep track of their resources. The idea has been around for a couple of thousand years but the technology was not advanced enough for us to make anything that resembles our modern computers till the 20 th century.

The first computers were analog devices that were used for solving different problems, that is they could perform an operation based on a predetermined mechanism that was usually based on a mathematical equation. That type of computer did not have enough flexibility to be used for many tasks and it could not be reprogramed. The first digital computer was called Z3 and it was developed in 1941 after successive models were upgraded.

The age that saw the birth of the computer also saw many changes in technology and manufacturing that made computer parts available for mass use. Those developments led to the invention of personal computers that were much cheaper and easier to use and once the public got hold of them a revolution in their usage was sparked.

The Present:

The present is all about computers and almost every home in the world has a computer, or that’s what we believe. The estimate from 2015 states that over 2 billion computers are in use today. The number suggests that there are a lot of devices all over the world being used every single moment. You are probably reading this from a computer and if not, you are reading it from a device that owes its existence to the computer and electronics revolution mentioned in the segment above.

Some people have suggested that computers are having a bad influence on people because they are making us distant from each other and because people tend to spend most of their day sitting in front of the computer looking like they are doing nothing. The fact is this is not something the computer does but rather the people who use them. Like with most other things in life that give us enjoyment we sometimes tend to misuse them and cause harm to ourselves.

The fact is that the present looks like it does because of the time and resources computers have saved us and this is an undisputed fact. Without this technology, we couldn’t manage half the production process running today not to mention our daily tasks that have in some circumstances become completely dependent on this device.

The Future:

Computers are becoming more complex and at the same time simpler to use making them widely distributed with a tendency to take over the world. There are many plans for the future of computers and as time goes by, they are capable of finding solutions to complex and unimagined problems. They are used in almost all the industries from mining to hospitality management and everywhere they find a unique task, or several, that they can perform.

They have become so indispensable to our lives that some people are actually considering making them a part of their body and integrating the computer operations with the organism. This can sound a bit bizarre but people are actually making advancements in this field and cyborg devices are being implemented to help people with disabilities more often as time passes.

The potential the computer has to help us is immense and the limit is only our imagination and the resources we have at our disposal. This tool can be thought to perform endless tasks even the experts get surprised sometimes. The future looks like its full of stars but we have to keep in mind that through their use we speed up all our processes altering our existence in a sense we have to keep both eyes open for signs of potentially dangerous outcomes of some of the technological advancements we use.

A computer, in terms of definition, is such a device, which through the use of computer programming, executes the arithmetic and logical operations. Computers are used as control frameworks for a wide assortment of modern and shopper gadgets. This includes simple gadgets like microwaves and remote controls, plant gadgets, for example, modern robots and computer helped structure, and furthermore broadly useful gadgets like computers and cell phones.

History of Computers:

Charles Babbage, an English mechanical designer and polymath, began the idea of a programmable computer. Considered as the father of the computer, he conceptualized and concocted the primary mechanical computer in the mid-nineteenth century. In the wake of chipping away at his progressive distinction motor, intended to help in navigational figuring, in 1833 he understood that a considerably more broad structure, an Analytical Engine, was conceivable.

The contribution of projects and information was to be given to the machine by means of punched cards, a strategy being utilized as an opportunity to coordinate mechanical weavers as the Jacquard linger. For yield, the machine would have a printer, a bend plotter and a ringer. The machine would similarly be able to punch numbers onto cards to be examined in later. The Engine consolidated a number juggling rationale unit, control stream as contingent stretching and circles, and incorporated memory, making it the primary plan for a broadly useful computer that could be portrayed in present-day terms as Turing-finish.

Parts of a Computer:

The essential parts of a computer are the computer case, monitor, keyboard, mouse, and power cord. Each part assumes an important role in the functioning of a computer. The computer case is the metal and plastic box that contains the principal parts of the computer including the motherboard, the CPU and power supply. The monitor works with a video card, situated inside the computer case, to show pictures and content on the screen.

Most monitors have control catches that enable you to change your screen’s showcase settings, and a few screens likewise have built-in speakers. The keyboard is one of the primary approaches to speak with a keyboard. There is a wide range of sorts of keyboards, yet most are fundamentally the same and enables you to achieve a similar essential feature. The mouse is another imperative device for speaking with computers. Ordinarily known as a pointing gadget, it gives you a chance to point to objects on the screen, tap on them, and move them.

Advantages of Computers:

Computers have no doubt made human life quicker as a result of extraordinary speed, accuracy and capacity, with which human can spare anything and pursuit it out effectively when required. We can state that computer is an adaptable machine since it is entirely adaptable in carrying out different occupations. The ability to do many tasks together, or in computer terms what is referred to as multitasking is one of the real advantages of a computer. An individual can carry out different undertakings, numerous tasks, and figure numerical issues within a couple of moments.

Computers can perform trillion of directions for every second. Other than this, one of the fundamental points of interest of a computer is its staggering pace, which causes human to finish their assignment in a couple of moments or even seconds. Each one of the activities can be performed in a quick manner in view of its speed otherwise it requires a long investment to complete the assignment.

Moreover, the storage capacity of computers is another of its abilities which make computers so powerful. You can store gigantic information inside a small hard disk. Concentrated database of putting away data is the significantly preferred standpoint that can lessen cost as well. One of the other advantages of computers is the precision of its calculations which are very hard to achieve manually.

The Other Side:

With the advent of technology, the computers have seen the darker side as well. Of late, there have been many instances of misuse of computers as well. For instance, viruses and hacking are two tools which are used to attack computers and misuse them. The virus is a worm and hacking is basically an unapproved access over a computer for some illegal reason. Viruses are exchanged from email connection, seeing a tainted site ad, through removable gadget like USB and so forth. Once malware is moved in host computer it can destroy the record, overwrite the document, and misuse them and so on.

For example, a huge bit of web was affected including Twitter, Netflix, and CNN in October 2016 on the grounds that the biggest DDoS assault was propelled on specialist organization DYN utilizing IoT Botnet. Such instances have given rise to cybercrimes. Cybercrimes imply computer system may have been utilized with the end goal to carry out unlawful activities. Cyber stalking and Identity burglary are the focuses which go under online digital crimes.

For example, one may get the access of your bank account or your shopping account like Amazon account and the hacker can have the capacity to access the bank account details or the credit or debit cards which can then be misused by the hacker. Moreover, with the increasing use of computers, there has been a decrease in the requirement of manual force as a lot of work has been taken over by computers. This was initially a cause of the increase in the rate of unemployment as well.

Computers – A Boon or a Curse?

There is no doubt that our lives have been made much easier with the introduction of computers. How easy it uses an ATM machine to withdraw money. In fact, online examinations which have removed the bias the students had to go through at the hands of teachers have been possible only with the use of computers. There are so many benefits of computers that is simply not possible to term them as a curse to our society.

However, everything must be sued judiciously, or else it does not take time for a boon to end up being a curse. For instance, we must make our kids understand the ill effects of using computers and cell phones for hours and encourage them to better reading and playing habits for them to go through their development process properly. Similarly, we must be aware of the cybercrimes one is prone to and follow the advice of the government from time to time in order to keep ourselves safe and secure from the ill effects of computers.

Short Essay on Computer in 200-500 Words

Computers have become an integral part of our daily lives. From the moment we wake up in the morning to the time we go to bed at night, we are constantly interacting with computers in some form or another. Whether it’s checking emails, browsing the internet, or using social media, computers have revolutionized the way we communicate and access information.

One of the most significant impacts of computers is their ability to store and process vast amounts of data. Gone are the days of keeping paper records and manually calculating complex equations. With the advent of computers, we can now store terabytes of data on a single hard drive and perform complex calculations in a matter of seconds. This has revolutionized industries such as finance, healthcare, and engineering, where data analysis and processing are crucial for decision-making.

Computers have also transformed the way we communicate with one another. With the rise of social media platforms and messaging apps, we can now connect with people from all over the world in an instant. This has made the world a smaller place and has allowed for greater collaboration and sharing of ideas. Additionally, computers have made it easier for businesses to reach their target audience through digital marketing and online advertising.

In the field of education, computers have revolutionized the way students learn and teachers teach. With the rise of e-learning platforms and online courses, students can now access educational material from anywhere in the world. This has made education more accessible and affordable for people of all ages and backgrounds. Additionally, teachers can use computers to create interactive lessons and assessments that cater to the individual needs of each student.

In the realm of entertainment, computers have opened up a whole new world of possibilities. From streaming services like Netflix and Spotify to virtual reality gaming, computers have transformed the way we consume media and entertainment. We can now watch our favorite movies and TV shows on-demand, listen to music from around the world, and immerse ourselves in virtual worlds that were once only possible in science fiction.

Despite all the benefits that computers bring, there are also some drawbacks. The rise of cybercrime and hacking poses a significant threat to our personal information and privacy. Additionally, the overreliance on computers for tasks that were once done manually has led to a decline in critical thinking and problem-solving skills.

In conclusion, computers have revolutionized the way we live, work, and communicate. They have made our lives more convenient and efficient, but also come with their own set of challenges. It is important for us to strike a balance between using computers to enhance our lives and being mindful of the potential risks they pose.

Essay on Computer in 1000-1500 Words

In today’s modern world, computers have become an integral part of our daily lives. From the moment we wake up in the morning to the time we go to bed at night, we are constantly interacting with computers in some form or another. Whether it’s checking our emails, browsing the internet, or even using them for work or school, computers have revolutionized the way we live, work, and communicate.

The invention of the computer can be traced back to the mid-20th century when the first electronic digital computers were developed. These early computers were massive machines that took up entire rooms and were used primarily for complex mathematical calculations and data processing. However, as technology advanced, computers became smaller, faster, and more powerful, eventually becoming the ubiquitous devices we know and use today.

One of the key reasons why computers have become so essential in our lives is their ability to process and store vast amounts of information quickly and efficiently. With the advent of the internet, computers have become even more indispensable, allowing us to access a wealth of information and resources at our fingertips. From online shopping to social media, computers have transformed the way we interact with the world around us.

Computers have also revolutionized the way we work and do business. With the rise of remote work and telecommuting, computers have made it possible for people to work from anywhere in the world, increasing productivity and efficiency. Businesses rely on computers for everything from managing inventory and payroll to communicating with customers and clients. Without computers, many of the tasks we take for granted in the workplace would be impossible or extremely time-consuming.

In the field of education, computers have also had a profound impact. Schools and universities use computers to enhance learning and teaching, providing students with access to a wealth of educational resources and tools. From online courses to interactive learning platforms, computers have made education more accessible and engaging for students of all ages. Teachers also use computers to create lesson plans, grade assignments, and communicate with students and parents, making the education process more efficient and effective.

In addition to their practical applications, computers have also had a significant impact on society as a whole. The rise of social media and online communities has changed the way we connect with others and share information. Computers have made it possible for people to stay in touch with friends and family around the world, fostering a sense of global interconnectedness. However, the rise of social media has also raised concerns about privacy and security, as well as the spread of misinformation and fake news.

Despite the many benefits of computers, there are also drawbacks and challenges associated with their use. One of the biggest concerns is the issue of cybersecurity, as hackers and cybercriminals continue to find new ways to exploit vulnerabilities in computer systems. From identity theft to ransomware attacks, the threat of cybercrime is a constant concern for individuals and businesses alike. As a result, there is a growing need for cybersecurity professionals to help protect our digital infrastructure and data.

Another challenge is the issue of digital divide, where certain groups of people have limited access to computers and the internet. This can create disparities in education, employment, and opportunities, as those without access to computers are at a disadvantage in today’s digital world. Efforts are being made to bridge the digital divide through initiatives such as providing affordable internet access and computer literacy programs, but more work needs to be done to ensure that everyone has equal access to the benefits of technology.

In conclusion, computers have become an indispensable part of our lives, transforming the way we live, work, and communicate. From their ability to process vast amounts of information quickly and efficiently to their impact on education, business, and society, computers have revolutionized the way we interact with the world around us. However, with these benefits also come challenges, such as cybersecurity threats and the digital divide. It is important for us to continue to innovate and adapt to the ever-changing landscape of technology, ensuring that computers remain a force for good in our lives.

Long Essay on Role Of Computers And Internet In Our Lives 500 Words for Kids and Students in English

Computer is perhaps the most controversial inventions of the 20th century. Ever since Bill Gates made it a household name, people have been debating over its merits and demerits. Most students would agree that the computer is the greatest invention on earth because it has opened up a vast store of easily available information for them. At a click of the mouse they get to learn all the things that help them to keep abreast with today’s fast moving world. However, for each positive aspect of the computer there is an equal or more negative counter points.

Gone are the days of vigorous handwriting practice. The computer has come as a blessing for students who can now submit their assignments in neat and legible sheets. They can loop up any information to put together their projects and use various software applications to present them in an impressive manner. Coloured graphs and diagrams can be inserted, there is very little scope of spelling errors and even grammatical mistakes are done away with.

Role Of Computers And Internet In Our Lives Essay

Knowledge increases with its spread and anyone who wants to spread his thoughts and knowledge can put it on the internet. It is available to the world and research students no longer need to labor through piles and piles of manuscripts. Universities can be contacted, websites can be consulted and even queries are answered through the internet . All this saves them a lot of time, labour, as well as money. For those who want to discuss, there are numerous e-forums and conferences that they can log onto. They can always indulge In a healthy interaction with other literary enthusiasts.

As computers become increasingly pervasive into our lives, an increasing number of people are facing problems on the domestic front because of computers and the internet. Individuals are spending hours on end chatting or surfing on the net, but they do not have time for the other members in the family. Each one is becoming less communicative and more dependent on the computer. Children, especially of the advanced and more developed countries are known to spend 20 hours a week playing computer games.

Alternately, computers are helping to build up a global family instead of narrow groups based on community and caste. The different groups that can be found on social networks are witness to the growing popularity on ‘international communities’. In a very short time people can be brought together, to protest against some wrong, to fight for some right or garner support for someone. As people become increasingly aware of what is going on in the world, more and more people are involving themselves in the service of other. There are doctors who can be consulted online, lawyers who clarify legal points and teachers who help students with their assignments. There are net cafes that allow people to play online video games – most of which show a lot of violence and aggressiveness.

Children, who spend a substantial time playing these games, believe that such violence is the accepted behaviour in life too. If on the other hand playing of video games can be restricted and supervised, children can develop better reaction time, visual activity and dexterity. Is it not amazing to know that a child sitting in the US may be playing a game with a child in Japan, or Australia? This international level of activity, excludes a lot of negative prejudices allowing the child to develop into a world citizen. However, the child can very easily get in touch with negative groups also.

Sadly, the advent of computers and the internet has rung the death knell on a lot of habits that are essential for the development of a good character. Reading is one such habit that is fast dying. Be it the daily newspaper or a work of fiction, the practice of group reading is decreasing. Communicative skills are deteriorating and health too is suffering because of the long hours spent sitting in front of the computer. It depends on our wisely making use of a computer to turn it into a boon instead of a bane for us.

What is a Computer?

A computer is an electronic device that accepts input, processes it, and produces output. Computers have been around for centuries in one form or another. Early computers were nothing more than simple mechanical calculators. The first true computers were created in the early 1800s. They were called difference engines, and they could perform complex mathematical calculations. Today, computers are an essential part of daily life. They are used in businesses, schools, hospitals, and homes. Computers come in all shapes and sizes, from small handheld devices to large mainframes.

The History of Computers

Computers have come a long way since their inception over 100 years ago. Early computers were nothing more than large, clunky machines that filled entire rooms. They were slow and difficult to use, and only a handful of people knew how to operate them. Today, computers are sleek, powerful devices that we carry around in our pockets. They’ve become an integral part of our lives, and it’s hard to imagine living without them. In this blog section, we’ll take a look at the history of computers and how they’ve evolved over the years.

The Different Types of Computers

Computers come in all shapes and sizes, and they can be used for a variety of purposes. The three main types of computers are the desktop, laptop, and tablet. Desktop computers are typically larger than laptops and have more powerful processors. They’re designed to stay in one place, like a home office or a business. Laptops are smaller and more portable than desktop computers. They’re designed for people who need to be able to take their computer with them, like students or professionals who travel frequently. Tablets are the smallest and most portable type of computer. They usually have touch screens and can run apps like phones.

How Do Computers Work?

Computers are amazing devices that can perform a variety of tasks. But how do they work? In this blog section, we will explore the inner workings of computers so that you can better understand how they function. We will start by looking at the basic components of a computer. This will include the processor, memory, storage, and input/output devices. We will then examine how these components work together to carry out the instructions given to the computer. Finally, we will discuss some of the ways that computers can be used in our everyday lives.

What Can You Do With a Computer?

A computer can be a powerful tool for performing many different tasks. With the right software, you can use a computer to create and edit documents, surf the web, listen to music, watch movies, and much more. In addition, computers can also be used for more advanced tasks such as graphic design, video editing, and even gaming.

How to Choose the Right Computer for You

There are so many different types of computers on the market these days, how can you choose the right one for you? It depends on what your needs are. If you’re a gamer, you’ll need a powerful machine with a good graphics card. If you’re a student, you might be able to get away with a less expensive model. And if you just use your computer for basic tasks like browsing the web and checking email, any computer will do.

Here are a few things to keep in mind when shopping for a new computer:

What will you be using it for? Games, work, school?
How much money are you willing to spend?
What is your preferred operating system? Windows, Mac OS X, Linux?
Do you need a laptop or desktop?
What kind of monitor do you want? LCD, LED, plasma?
Do you need any special features like Bluetooth or a webcam?

Once you’ve considered all of these factors, it should be easier to narrow down your choices and find the perfect computer for you.

How have Computers Changed over Time?

Computers have changed a lot since they were first invented. They’ve become smaller, more powerful and more portable. Here’s a look at how computers have evolved over the years. The first computers were large, bulky machines that took up an entire room. They were expensive to build and maintain, and only a few people knew how to use them. Today’s computers are small enough to fit in your pocket and powerful enough to perform billions of calculations per second. They’re also much easier to use, thanks to user-friendly interfaces and intuitive controls. The first computers used vacuum tubes and magnets to store and process data. This made them slow and unreliable. Today’s computers use semiconductor chips, which are millions of times faster and more reliable. In addition, modern computers can store billions of pieces of information on tiny memory chips. The first computers were built for government and military use. They were used for tasks like tracking missiles and calculating missile trajectories. Today, most people use computers for personal tasks like checking email, browsing the web and playing games. Computers have also become essential tools in businesses and industries of all kinds. As you can see, computers have come a long way since they were first

In conclusion, the computer is an amazing tool that can be used for a variety of purposes. From keeping us entertained to helping us stay connected with loved ones, there is no limit to what a computer can do. Whether you use a PC or a Mac, computers are an essential part of our lives and will continue to be for years to come. Thanks for reading!
