In this article, we will try to reveal all possible things related to different types of digital computer with their classification without any hassle.
Overview of Digital Computer
Digital computer is an electronic device that has ability to process information at higher speed. These types of computer requires the input data that it can process and finally it provides the output data through output devices of computer like as monitor, printer and plotter.
ENIAC (Electronic Numerical Integrator and Computer) was one of the first digital computers.
Digital computers get process the binary input (0 or1) format and produce the accurate output to users. These computers are fastest, higher precision, most accurately, and offer the enormous data storage compare to analog computers.
Types of Digital Computer
Digital computer is divided into two categories like as general purpose and special purpose computers. Most popularity of digital computers is general purpose that means they have abilities to manage couples of applications and control many variants of functions.
Classification of Digital Computer
Further, digital computer can be divided into four segments according to their size, capacity and performance such as:
- Micro Computer
- Mini Computer
- Mainframe Computer
- Super Computer
Explain Different Types of Digital Computer with Examples:
Micro computer is small size and less expensive computer with containing the different types of microprocessor as its CPU. This computer is designed with using of microprocessor, memory as well as input/output circuitry embedded on the one printed circuit board.
Few microcomputers are enabled with other components like as counters, timers, and analogue-to-digital converters. They are built with minimum one data storage device like as RAM. This computer uses the many types of monitor, mouse, and keyboard for input and out.
Microcomputer Examples are: PDA, PC, Laptop, Handheld Computer, Smartphone, Notebooks, and Tablet devices.
Applications are: Education, Application processing, and Amusement, so on.
Minicomputer was firstly introduced in mid-1960 year.
Minicomputers are also called as mid-range computers. They consist one or multiple types of processors that are linked to a common memory and similar peripheral devices to perform different kinds of tasks simultaneously. Minicomputer also consists has great complexity compare to microcomputers.
Therefore, this computer is getting more popularity for their quality of multiprocessing, and usually used for many applications such as data handling, engineering computations, and managing database.
Minicomputers are inexpensive than supercomputer and mainframe computers, but they are most powerful compare to microcomputers. Minicomputer lets multiple users at a same time and support multiprocessing and multitasking to execute multiple tasks simultaneously.
Examples are: Smart phones, PCs, Laptops, Mini-Desktop and high end MP3 player.
Applications are: Processing monitoring, Data acquisition, Feedback, and etc.
Mini computers are mostly used by businesses to handle the process of production.
Mainframe computer was firstly designed in 1930 but this was properly functional in 1943. Harvard Mark 1 was the first mainframe computer.
Mainframe computers are mostly used in large organizations to handle complex operations like as transaction processing, bulk data processing, and enterprise resource planning. They are able to perform higher to any other types of computer system; and they consist a enlarge of memory and multiple ultra-processors.
Mainframe computer has two major components like as JCL and COBOL. JCL stands for ‘Job Control Language’, and stretchy and authoritative language that lets to customize and operate the remote resources for these computers. Other hand, COBOL (Common Business Oriented Language) is used to get process the data in business sector as high level language.
Mainframe computer Examples are: Banking, Government, Insurance, Education system mainframe computer and more.
Applications are: Large IT organizations, Walmart, NASA, etc.
Super Computer has thousands of processors that able to execute trillions instructions in per second. Supercomputer needs an entire room for its set up and performing their operations. So, this needs also a external cooling pipes to control the generated heat. Therefore, this computer is mostly used such organizations where needs to massive calculations like as National Nuclear Security Administration, NASA, ISRO, etc.
Super Computer Examples are: Titan, Sequoia, K Computer, Mira, JUQUEEN, SuperMUC, etc.
Applications are: Weather forecasting, stock analysis, Gas exploration, Polymers, Biological macro molecules, Crystal’s scientific simulations, Fluid dynamic calculations, Animated graphics, Electronic design, Geological data analysis and Nuclear energy research
