Type of computer
Generally computers are divided into three parts, analog computers, digital computers, and hybrid computers. Out of these, digital computers are also divided into four parts, mini computers, micro computers, main frame computers, and super computers.
Analogue computer
An analog computer is a type of calculating machine that uses physical phenomena such as electrical, mechanical, or hydraulic quantities that behave according to mathematical principles to solve problems.
Analog computers are mostly used in the fields of medicine and science.And analog computers are generally used to measure physical quantities such as temperature, distance, length, height etc. Analog computers accept analog data signals as input and process analog data to give output in analog format
Working of analog computer: Analog computers process information using continuously changing physical quantities, such as current, voltage, and pressure. These quantities can take any value within a given range, and they are represented and processed using analog circuits and devices, such as resistors, amplifiers, and capacitors.
Digital computer
A digital computer is an electronic device that can store large amounts of data and is able to perform a set of arithmetic calculations and logical processes at high speed. A digital computer is a computer that uses the digital technology of 0 and 1.
It processes digital results that have different values, most computers work on this system, and this digital computer gives accurate results at a faster speed than any other computer.
Use of digital computer
Digital computers are generally used in schools, colleges, hospitals, railways etc. and places to store data.
Presently digital computers are used for various purposes like filling online forms, watching videos, etc. and using the internet.
Digital computers are used a lot in the field of education, nowadays students are able to do online studies or any other studies at home with the help of digital computers.
Digital computers are generally used to store any type of data.
characteristics of digital computer: Digital computers are able to solve problems by processing information in a simple way; they work with data that consists of characters, numbers, and symbols that are expressed in binary code that has only two digits 0 and 1.
Type of digital computer
The classification of digital computers is divided into four main categories based on their size and type, microcomputers, minicomputers, mainframe computers and super computers.
Micro computer
A microcomputer is a small scale complete computer, which is designed for individual use, microcomputer can be used by only one person at a time, microprocessor is used in place of CPU in microcomputer i.e. its CPU is based on microprocessor.
Use of micro computer:Micro computers are widely used for various tasks like internet browser gaming and data processing, its size is small and light in weight so it can be carried anywhere, micro computer can be used by a single person, various types of software can be run in micro computer.
Mini computer
Mini computers are those which are small in size but their functions and factors are very big, mini computer is a multi user computer, which is mostly used for server computer work in big companies and government offices, many users can work on this computer simultaneously and its working capacity is more than micro computer. Mini computer is a medium computer which is between mainframe computer and micro computer, mini computers are smaller than mainframe computers and larger than micro computers, mini computers include laptops, tablets etc.
Use of mini computer: A mini computer is a small device that works like a radio-connected computer, that is, it is capable of performing tasks like sending emails, using a browser, sending photos and running applications on the Internet.
Micro computer
A microcomputer is a small scale complete computer, which is designed for individual use, microcomputer can be used by only one person at a time, microprocessor is used in place of CPU in microcomputer i.e. its CPU is based on microprocessor.
use of microcomputer: Micro computers are widely used for various tasks like internet browser gaming and data processing, its size is small and light in weight so it can be carried anywhere, micro computer can be used by a single person, various types of software can be run in micro computer.
Mainframe computer
Mainframe computer is bigger than mini computer and micro computer. This computer works as a server, mainframe computer is used to keep database in big companies, mainframe computers are very big in size, so they have the ability to process large amount of data fast, mainframe computer can process several crores of instructions in a second and it can work 24 hours, hundreds of users can work simultaneously in these computers, thousands of microprocesses are installed in mainframe computer, this computer can be connected with a network, mini computer and micro computer.
Use of mainframe computer: Mainframe computers have the capability to process large amounts of data very quickly. As mainframe computers are large in size they are used in big companies, banks, railway reservations and government departments as they have large memory and processing power to handle billions of calculations. Mainframe computers can be connected with microcomputers, minicomputers and a network.
Super computer
Supercomputers are the largest and fastest computers in the world and are designed for specialized tasks. They are powerful, highly accurate machines that are capable of processing huge sets of data and performing complex calculations at very fast speeds.
What makes a supercomputer super is its ability to interconnect multiple processors within a single system. A supercomputer has to handle a large database. In a supercomputer, many CPUs work in parallel, which is why their working capacity is very high. A supercomputer has thousands of processors installed which are capable of doing thousands of crores of calculations per second. This computer uses parallel processor to work, in which it divides a task into small parts and each microprocessor does each task separately, in it all the tasks are done simultaneously. Linux operating system is used in most supercomputers.
Use of supercomputer: Supercomputers are used in areas where large-scale calculations are required. Traditionally, supercomputers have been used for sensitive and engineering applications that can handle large databases. Historically, supercomputers have also been used for weather forecasting, air search, nuclear arsenal calculations, mathematical modeling, etc
Hybrid computer
Hybrid computers are those computers which are made up of both analog computers and digital computers, and analog computers show the features of digital computers, these computers are capable of processing both controlled generated data and digital data,
due to the availability of both digital and analog features these computers are called hybrid computers.
Working of hybrid computer: Hybrid computer is such a computer whose purpose is to provide functions and facilities of both digital and analog computers, applications that process both continuous and discrete data work in hybrid computers, this type of computers give signals to the analog computers and convert them into digital form before processing, hybrid computers are used in places where both analog and digital computers have to be processed. It is mainly used in petrol pumps, airports, science field, and medical field etc.
