The Mainframe Computers. It consists of a monitor and a casing inside which the power supply, the CPU, the motherboard and many other devices are located. The chassis also contains slots for expansion boards. Sometimes, they can have multiple terminals which consist of screens, keyboards and mice. 2.Mainframe computers — These are large and expensive computer types capable of supporting hundreds, or even thousands, of users simultaneously. Desktop computers, laptops, personal digital assistant (PDA), tablets & smartphones are all types of microcomputers. Each of the above types of computer has different variants especially with the emergence of latest technology in computing. There are basically four different types of computer system namely super,mini,mainframe,micro.They are classified by size and capabilities. The term "microcomputer" has practically become an anachronism. This is a guide to Types of Computer Hardware. The micro-computers are widely used & the fastest growing computers. The chassis or case is the metal frame that serves as the structural support for electronic components. Although some supercomputers are single computer systems, most are composed of multiple high performance computers working in parallel as a single system. However, for the sake of simplicity, Classification of computer system has been discussed separately in one of my articles in this website. In what follows, the different types of personal computers are discussed. Embedded computers are … It is a collection of a number of different hardware devices. Recommended Articles. Every computer system requires at least one chassis to house the circuit boards and wiring. Major types of computer system to some analysts are synonymous with Classifications of Computer systems. 1 A desktop computer is designed to be used at a desk and seldom moved.. The Micro-computers are specially designed for general usage like entertainment, education and work purposes. This type of computer is sited permanently on a desk because its design means it cannot be easily moved. Actual personal computers can be generally classified by size and chassis / case. The best-known early system was the Altair 8800, introduced in 1975. This type of computer usually costs hundreds of thousands or even millions of dollars. Computer architecture consists of rules and methods or procedures which describe the implementation, functionality of the computer systems. Different type of hardware device has a different role. A desktop computer is the most common kind of PC. Embedded computers. DIFFERENT TYPES OF COMPUTER SYSTEMS A computer is a general purpose device which can be programmed to carry out a finite set of arithmetic or logical operations. These computers are the cheapest among the other three types of computers. Introduction to Types of Computer Architecture. and games consoles are typical, everyday computers but there are many other types of computer systems. The monitor, keyboard, and mouse all plug into it using cables (or in some cases, using a wireless technology). The hardware devices vary in size, specification and it should be chosen as per the compatibility of the computer system. The common components of a desktop PC are: the system unit containing the processor and main memory The term “microcomputer” was introduced with the advent of systems based on single-chip microprocessors. They have powerful processors with enormous memory for backing up large amount of data. III, Personal Computer Types. Thus, they are mostly used by governments and large organizations for bulk data processing, critical applications, transaction processing, census, industry and consumer statistics … Well known … Mainframe Computers. There are different types of computer system: Personal computer, Workstation, Minicomputer, Mainframe and Supercomputer. Architecture is built as per the user’s needs by taking care of the economic and financial constraints. Feel free to make … It consists of a large box called the system unit that contains most of the essential components. Desktops are the most … These types of computer systems can be multi – programmed. The second types of computer systems are the desktop computer systems. And a complete set of hardware devices makes an effective computer system. Microcomputers became the most common type of computer in the late 20th century. The best known supercomputers are built by Cray Supercomputers. They’re not common as they are very expensive.
