What is computer? Its Basic Information | Easy and Quick

If you want to about what is computer? In this post, we cover the basics of computers that can be very useful and easy to understand. Well, there are all kinds of computers. Some of them are very large and some are very small. You’re probably talking about a personal computer – the kind you have at home. This could be a desktop computer, or a laptop, or a tablet. Even your smartphone is a computer.

Why do we need all these computers?

Computers compute! Do you know what that means? Like adding and subtracting? Right! Computers see the world as if it’s made of numbers. Actually, just two kinds of numbers: ones and zeroes. By making everything very simple, adding and subtracting ones and zeroes, computers solve problems way faster than people can!

What are uses of computer?

You can use a computer to do work, but you can also use a computer to play games and have fun! You can use it to do your math homework, or draw a picture, or go on the Internet. We send emails using computers. You can talk to anyone on a computer, using video chat! They’re only as smart as their software – that’s the instructions that tell the computer what to do.

Which part is the software? Can we point to it?

No. We can’t point to the software. All the parts you see that’s the hardware. Computers work by combining hardware and software. Hardware is anything physical – anything you can see and touch. Like the monitor, the keyboard, and all the parts inside the computer- all those wires and circuits – that’s where the real work gets done. On this circuit board, you’ll find a computer’s CPU, the Central Processing Unit. That’s like the computer’s brain.

Hardware Components

The computer system is made of:-

  • System Unit
  • Keyboard
  • Monitor (VDU)
  • Mouse
  • Modem
  • Multimedia Devices
  • Printer

System Unit consists:-

  • The Processor (CPU)
  • Memory: RAM and ROM
  • Storage: Hard Disk
  • Removable Storage Devices

What is Processor?

It does the calculations, seed is very important and measured in megahertz (MHz): the faster the processor the more calculations performed per second.

What is RAM?

Random-access memory is used as a working area of the computer, it holds the working program, data being used, and also results.

What is Hard Disk?

Permanent Memory- records and stores all programs and data/ information magnetically larger than RAM but slower – involves mechanical movement.

Input Devices

  • Keyboard
  • Mouse
  • Joy Stick
  • Mic
  • Barcode Reader
  • Web Camera
  • TouchPad
  • Touch Screen
  • Finger Print reader
  • Stylus Pen

Output Devices

  • Headphone
  • Printer
  • Monitor
  • Speaker
  • Microphone

What is software?

Software is the set of instructions that tell the computer what to do. The computer doesn’t have any idea what it’s doing. In fact, it won’t do anything at all ever – unless you tell it to. You need to be very careful about what kinds of instructions you give your computer, or it won’t work properly. the step-by-step instructions you give your computer. One set of instructions is called a PROGRAM. One more thing, We’ve been speaking English to your computer, but computers actually speak different languages. Computers speak computer languages. For example Python, Java, C. Those are all names of computer languages. Computer programmers learn these languages so they can talk to computers.

Can anyone become a computer programmer?

Sure, Everyone can learn how to code. It’s just like solving a puzzle. Would you like to become a programmer? If you have a computer you can play around and learn what happens when you give it different instructions. Tell us in the comments about how you use computers. I bet you’re using one right now! Now we learned about computers, that was great! So we hope that now all of you understand What is computer?
