computer hierarchy

Old method for comparing various computer classes are based on processing power. Analysts typically divide the computer into six categories: supercomputers, mainframes, midrange computers (mini computers and servers), workstations, notebooks, and PCs and various equipment.


Supercomputer

 The term does not refer to the supercomputer particular technology, but on the fastest computing machines are available in a period. Supercomputers usually handle the job very complicated for a series of very large data. Rather than just for processing and business applications, supercomputers typically run military and scientific applications, although its use for commercial applications, such as data mining, has increased. General supercomputer operates four to ten times faster than the next fastest computer classes.


Mainframe Computers

Although mainframe computers more and more regarded as another type of server, based on the sophistication scale performance and reliability, the mainframe remains a distinct class of system hardware and software features. Mainframe still popular in many large companies to komputansi broad applications and are accessed by thousands of users. Examples of mainframe applications include airfare reservation systems, payroll companies, and the calculation and reporting of student values.


Midrange Computers

Minicomputer also called, are relatively inexpensive, small, and compact, which perform the same function with mainframe computers, but in a more limited scope. Even the line between mini-computers to mainframes becomes less clear in terms of cost and performance. Minicomputer usually supports computer networks, allowing its users to share files, software, peripherals, and various other network resources. Minicomputer can provide flexibility for companies who do not want to spend money on IT in the form of mainframes that are less measurable.

Midrange Computer smaller is called the server. Servers are typically used to support the network, allowing users to share files, Software and other network equipment. Companies that have a great need for e-commerce website and have a very large often run the web and various e-commerce applications through several servers.


Workstation

The vendor computer workstations initially developed to provide a high level of performance required by the technicians. Thus, a workstation running the application of scientific, technical, financial and quite complicated. Workstations are usually based on RISC architecture (reduced instruction set computing) and provides high-speed calculations and high resolution graphics display. Computer is getting wide acceptance in the scientific community and recently in the business community.


PC

Pc became the dominant method to access workgroup applications. This computer is a system of ordinary microcomputers and general and that has become a standard tool for businesses, and more and more also for home. Computer is usually designed modular, with separate but connected monitor, keyboard and CPU.


Notebook

Microcomputers, notebooks are small, portable, and lightweight. Computer is designed for maximum comfort and convenience to carry, allowing access to processing power and data outside the office environment. It costs more than desktop for the same functionality.
