Types of computers
Types of computers can be classified based on:
1. According to the Processed Data Types
*Analog computers; is a computer that works in parallel (analog) to process the continuous nature of data, data of physical quantities and figures (quantitative) as temparatur, air pressure, wind speed, current sound waves, etc.
Example: Amperemeter, Voltmeter, Barometer, Thermometer
*Computers Digital; is working on a computer count operations. Variable in the computer is indicated by the numbers. Problem solving is done by the arithmetic and logic (quantitative).
Example: Calculator, Apple IIe, IBM PC
*Computers hybrids; is a computer that works qualitatively and quantitatively. This computer is a combination of analog computers and digital computers.
Examples of this type of computer is used by computers on the robots to be used as a factory worker.
2. According to the Data Processing Capabilities
Small computer (Micro Computer)
Medium-size computer (Mini Computer)
Computer-size (Large Computer)
Computer super size (Super Computer)
3. According to Field Problems
*General Purpose Computer; used to handle all kinds of problems both business problems and others. Computers of this type are usually suitable for personal computers (PCs).
*Special Purpose Computer; is a computer that is used to treat one type of special problems. This kind of computer system usually has filled a special kkomputer program, which is usually used as controls certain processes in plant machinery, military or medical examination. Thus if the terms of the processed data then this kind of computer system usually uses koputer hybrid capabilities.
4. According to the Electronic Components (Processor)
*Mainframe Computer; Computer processor type uses that have a very large capacity and is intended for multi-user. By using time-sharing technology, the effect is not so perceived by the user. This type of computer has a Central Processing Unit, Storage Device a rather large (about the size of a closet 2) and placed in a separate place. CPU and storage equipment is connected to many terminals consisting of a keyboard and monitor it. Terminals can be connected by the thousands in accordance with the needs of the computer san mainframenya series. type of computer is suitable for large-scale companies that many have many branches.
*Mini Computer; Capacity processors used almost the same as the mainframe, only the number of terminals that can be connected to the computer is not as much as on the type of mainframe computers. The number of terminals that can be connected only dozens. Therefore this kind of computer system suitable only for middle-class companies that are not so big and not too small. The physical size of the computer is not as large mainframe computers.
*.Personal Computer (PC); type of processor used abilities are not so large compared with the mainframe computer. Because this computer is intended for a user. Because of the usefulness of this type of machine called a personal computer or Personal Computer (PC). This computer has all the tools that have been assembled IPO into one. We have developed PC skills and usefulness.
5. The shape and size according to the Physical
*Computer Desktop; quite small physical size, typically matched placed on the table. Bhakan now developed a form of desktop computers known as thin with slim desktop form. This desktop form usually comes with lots of space called expantion slot as a place for an additional card.
*Computer Tower; Fisk size is relatively larger than the type of desktop computer, suitable to be placed alongside or on the table. Have room for more slot expantion.
*Portable computers; physical size is slightly smaller than a desktop and tower computers. All the parts are put together so you can easily carry anywhere. Type of computer was created for people who often work to move or the field. Portable means freely portable.
*Laptop Computers; is a computer with a physical size that can lap, was smaller than portable computers, all components are made together.
*Computer NoteBook; accordance with the type of computer is the physical size of notebook, shape and size similar to laptop computers.
Subnotebook computers; kwarto size of paper, thick about 5 cm, and are still being developed to shrink the size.
*Palmtop computers; Computer is designed to be gripped, when compared with the tape measure about the size of beta tapes. Electric currents through the battery obtained.
