What Makes a Computer?

There are computers in almost every room. People carry them in their pockets, in their gondolas, on their wrists, and they may even be in your backpack right now, but what exactly is a computer? So, what exactly constitutes a computer? What difference does it make, anyway?

I’ve been dealing with computers since I was about 17 years old, and now I specialize in virtual reality. We have always constructed tools to assist us in solving difficulties as humans. Wheelbarrows, mallets, printing presses, and tractor trailers are examples of implements. All of these skills came in handy when working with our hands. Over time, people began to question if a computer could be created to assist us in our reflective work.

Solving math or keeping track of the stars in the sky are examples of this type of activity. Instead of moving or manipulating actual objects such as grease or stone, these robots would have to be developed to manipulate data. As computer scientists investigated how to construct a thinking machine, they discovered that it would have to complete four tasks. It would have to receive grocery data as input, process it, and then output the research findings. This may appear straightforward, but all computers share these four characteristics.

That is what a computer is made up of. Wooden and metal computers with mechanical bars and gears were the first computers. Computers, however, began to exercise electrical components during the twentieth century. These early computers were enormous and sluggish. Simply solving a fundamental math problem on a computer the size of a chamber may take hours. Computers began as simple calculators, which were really rather amazing at the time, and they could only manipulate multitudes.

However, we can now use them to communicate with one another, play games, create self-restraint robots, and do just about anything else you can think of. Modern computers may not resemble those clumsy old machines, but they perform the same four functions. We’ll begin by discussing input.

This is my favorite since input refers to the things that the world does or that you do that causes computers to do things.

You can instruct a computer what to do through the keyboard, mouse, microphone, and camera, and now if you wear a computer on your wrist, it might listen to your heartbeat or what your car is doing. A touchscreen, on the other hand, can detect your paw and use it as input for its creation. The computer receives information from all of these distinct sources, subsequently stored in memory.

A computer’s processor receives data, manipulates or converts it using a consuming algorithm (which is simply a series of words), and then returns the process data to memory.

This method repeated until the data has processed and ready for output. What a computer meant to do determines how it sends messages. Text, photographs, videos, interactive games, and virtual reality can all displayed on a computer display. Signals to control a robot could included in the output from personal computers. When computers communicate via the internet, the output of one becomes the input of another, and vice versa.

Today’s computers are vastly different from the first thinking machines. Who knows what computers will look like in the future. My hope is that you will be able to participate in the design of future personal computers. However, no matter what type of technology “they’re utilizing,” all computers do the same four tasks. They collect data, organize it, manage it, and finally output the results.
