Classes of computers – Types of computers
Friends, in this post today, we will get to know about Classes of computers or types of computer and what are characteristics of computer, before that we will learn about a little computer.
What is Computer – Classes of computers
A computer is a machine that works on the instruction of a human, the instruction that we give to the computer, the computer also gives the result on the basis of the instruction. The computer completes the largest calculus in seconds, the computer’s efficiency is very high.
If we talk according to the speed and size of the computer, then there are 4 types of computers.
- Mainframe computer
If we understand the type of computer through this diagram, then there are four types of computers, in which the first supercomputer is the last and the microcomputer.
As we move upwards, the speed of the computer becomes fast, expensive, complex and large.
If we come down from the top, that means the supercomputer comes down from the supercomputer, the way computers go slow, cheap, simple, and small.
Friends, if you are asked about the difference of types of computer or Classes of computers, then you can tell the difference through this diagram.
Super computers are the fastest computers and these computers are very expensive. Super computers are very difficult to operate, meaning super computers are very large in complex as well as size.
Supercomputers can perform more than 1 trillion calculations in a second. Supercomputers were designed so that fast calculations and large amount of data can be stored.
More than Thousands of processors are connected in a supercomputer. Supercomputers are most commonly used in scientific and engineering such as weather, forecasting, and research etc.
2. Mainframe computer
Mainframe computer has more capacity than super computer. Multiple processes run simultaneously in mainframe computer. Mainframe computer can execute maximum number of processes simultaneously.
But Supercomputer tries to do a work quickly. Both computers are used for different tasks. If we have to do a job quickly, we use super computers if we have to do a lot of work. We use a mainframe computer to do it together
Mainframe computers can operate from 100 to 1000 users simultaneously. Mainframe computers support multiple programs at a time. Mainframe computers are used in large organization, bank and telecommunication sectors. Mainframe computers are more fast and expensive than mini computers. Are and their size is bigger than mini computer, that is why this computer is more powerful than mini computer, it can work 100 to 1000 uses simultaneously.
3. Mini computer
We also know mini computers as mini frame computers. These computers are midsize multiprocessing computers. There are more professors in mini computers. In this, 100 to 200 users can work together. Mini computer is used in institute and department. Used for work like billing system, accounting and inventory management etc.
Mini computer size is less than mainframe computer but bigger and more powerful than microcomputer.
The microcomputer we know as a personal computer is most commonly used today. Microcomputers are being used at home today. Microcomputers were designed for personal. It includes a CPU and a memory unit, input. And the outputs are units such as laptops, desktops, and smartphone is examples of microcomputers. These types of computers are used for personal work. Microcomputers are used for multitasking such as movies, MS Office and web browser, etc.
what are characteristics of computer – Computer features
Friends, above we read about Classes of computers or types of computer and now we will know what are characteristics of computer, by the way, there are many Characteristic of computer. Today we will learn about what are characteristics of computer by this post.
what are characteristics of computer
The work that Human takes an hour to do, the computer takes a few seconds to do the same work. Computer completes the biggest calculus in seconds. The speed of functioning of the computer is very high. The computer executes 10,00,000 instructions in a second. The computer is a very fast calculating device.
A computer does its job with full accuracy, there is no chance of a mistake from a computer because a computer is a machine. The work we give it works according to it. A mistake can be done by a human but not by a computer. Always gives the right result, its accuracy is very high.
In order to store data and files on the computer, we need storage. The computer has two types of memory. Primary memory and secondary memory. Primary memory has data saved for some time but in secondary memory, data is stored for permanent storage.
The computer can perform more tasks than millions and the computer does not need to take any fatigue and break in doing this task, it keeps on doing its work continuously with accuracy.
A computer is an automatic machine that keeps on working non-stop, after giving instruction to the computer, the computer continues to work continuously.
Like when we watch a movie on a computer, we have to open the movie once, after that the movie continues to play for 2-3 hours.
Through computer, we can run multiple tasks at one time. Versality means that performing multiple tasks at the same time by one machine is called versality.
