1. Supercomputer Systems
Supercomputer systems are the fastest, most powerful, most expensive computer. Used for applications requiring complex mathematical calculations (100 Trillion instructions per second). Supercomputer are extremely designed for scientific, engineering, and business applications.
2. Mainframe Computer Systems
Mainframe computer systems are very powerful, expensive computer that supports thousands of computers.Mainframes have even more access to storage space and to input or output devices. Mainframe is useful and required by large corporations who have large amounts of data to process.
For example, overseas banks need mainframe to maintain their customer account records (like their bank account balance,withdraw, deposited) so that the customer can doing transaction at any of the branches.Mainframe is becoming a popular computing platform for data mining and warehousing. Besides, mainframe is important to electronic commerce applications too.In the early 1990s, there was a consensus among industry analysts that the mainframe was a dying market as mainframe platforms were increasingly replaced by microcomputer networks. Counselors began to interface with microcomputers much more, it is prompt within the world of business.
3. Midrange Computer Systems
Midrange computer systems are the high-end network servers that handle large scale processing of business applications. It is not as powerful as mainframes computers. It normally used as front-end servers to assist mainframes with telecommunications and networks.
4. Microcomputer
Microcomputer usually called a personal computer or PC. Dekstop computer and notebook computer, tablet PC are all categories as microcomputer.Microcomputers can be grouped into five smaller groups; the workstations, desktops,servers, laptops and notebooks.
desktop computer
Desktop computer was designed so all of the components fit entirely on or under a desk or table.
notebook computer
Notebook computer is portable, small enough to fit on your lap. It also called a laptop computer.Notebook computer generally more expensive than a desktop computer.
Microcomputer can computing power now exceeds that of the mainframes of previous generations. The advantages of microcomputer is it relatively inexpensive. It also a networked professional workstations used by business procession. Nowadays, almost every household have at least one microcomputer. Microcomputer is easy to carry and can access to the network. Besides, it can replace televisyen, because it can allow users to play song, movie and have a lot of features that prefer by users. But it just allow one user to use only.
Workstations computer generally refer to machines used for intensivecalculations on designs such as architecture and buildings.while other computers are used as network servers.These are usually more powerful microcomputers that coordinate telecommunications and resource sharing in small local area networks and in internet or intranet web sites.
5. Mobile computers
Apple IphoneMobile computers are the develop of microcomputers an it also called hand-held microcomputer devices. Nowadays, almost everyone have at least one mobile computer. Mobile computer is a small computer that can be carried in pocket.
Handheld computer devices is also known as personal digital assistants (PDAs).PDAs are a very recent enhancement of electronic productivity tools based on microprocessor technology. It can access to wireless and allow user to access the web. Personal Digital Assistants such as Apple’s iPhone, Blackberry provide business people, and technocrats, with common daily organisation tools (such as a diary, telephone book, notepad) in a small packaging usually no larger than a stenographer or short-hand notepad.
