What is Computer System | Definition of Computer. Hello, today I’m going to show you an easy way to learn what is a computer system and the best definition of a computer. In this post, I will explain how does a computer system work in detail.
This article is the best on the whole internet. I guarantee you, after reading this article you will not need to read any other articles. In fact, our readers are satisfied with this blog post.
What is Computer Definition?
A computer is an electronic machine that uses inputted data to perform mathematical or logical operations and provides the required results or information.
In other words, it is a smart device that runs on electricity, is programmable, and only works with the combination of hardware and software. The word “computer” is derived from the Latin word “computare,” which means calculation.
Computers have come a long way since their early days of only being able to perform calculations. Nowadays, computer systems can not only calculate but also carry out many other tasks.
This is due to the characteristics of computers today that make them so versatile and useful in so many different settings. For example, you can find computers in schools, colleges, offices, banks, and airports all around the world.
What is Computer Full Form?
The full form of “computer” is “commonly operated machine particularly used for trade, education, or research.” This is a very popular full form of computer.
| C | Commonly |
| O | Operated |
| M | Machine |
| P | Particular |
| U | Used |
| T | Trade |
| E | Education |
| R | Research |
How does a Computer Work?
Today I’m discussing the inner workings of a computer system and the steps it takes to complete any given task.
A computer system is essentially made up of four modules, which are listed below.
- Input
- Processing
- Output
- Storage
1.) Input
Data is inputted into a computer by using input devices such as a keyboard, mouse, or microphone.
Users input data or instructions into a computer using input devices. Examples of input devices include keyboards, mice, and microphones.
Q. Which types of data input by the Keyboard ?
Ans – The keyboard is a great tool for inputting all sorts of text data, whether it’s a word or a number. A keyboard is a great way to input text data, whether it’s a word or a number.
Q. Which types of data input by the Mouse ?
The computer mouse is a great tool that allows us to input data onto the monitor screen with clicks. For example, we can open and close files, applications, and folders or minimize, maximize, and close the computer screen.
Q. Which types of data input by the Microphone ?
With the help of a microphone, we can input voice data into the computer. For example, I can say “open my computer icon” and the computer will recognize the voice data and open my computer. Today’s computers are very smart and can accept all types of instructions from users.
I hope this answers your question!
2.) Processing
Any type of data that is inputted by the user, that data or instruction computer understands which type of data or instruction is.
- Like is arithmetic data or logic data.
- All the processing function is done by the CPU. A CPU is a microprocessor chip.
- This microprocessor chip is very faster than the human brain.
3.) Output
After we input data into a computer, that data is processed and turned into an output. We can see the output on the monitor screen. There are several types of output devices, and we can choose to print the output as a hard copy.
4.) Storage
Space is required to display the result that comes after processing. Output results without storage will not be displayed.
A computer has a storage device to store data. There are two types of storage devices: temporary storage and permanent storage.
Whenever the computer displays the results after processing any data, it is the temporary data which is stored in the temporary storage (RAM). If we save the result that comes after processing, then that data is saved from temporary storage (RAM) to permanent storage.
I hope you understand.
