Pc Computer
Definition and Full Description: What Is a Computer?
A. Computer Definition
Human life in contemporary times can not be separated from technology, especially computers. In fact, so much of the equipment based on computer technology that are now commonly used, for example, I-pad, Tablet, Smartphone, Mobile Computer as a desktop and laptop computers, global positioning system, or GPS, translator, even Computer- based watches and many others.
Some computer experts and Researchers interpret as follows :
1. According to Hamacher Opinion
"The computer is a fast electronic calculating machine, and can receive digital input information, then process them in accordance with the program stored in memory, and generate output information".
2. According to Blissmer Opinion
"The computer is an electronic device that is capable of performing Several tasks, the which accept input, process the input According to instructions given, save the command and its products, as well as providing output in the form of information."
3. Fuori Explain that :
"The computer is a processor of data that can perform large tally quickly intervening, Including the calculation of arithmetic and logic operations, without human intervention".
The third is based on the opinion it can be concluded that the computer is a set of electronic devices Comprising an input device, a tool that processes input and output devices that provide information, and works automatically.
B.Computer Classification
Recent literature classifies computer based on four things, ie the the data are processed, use, shape and size, as well as generation.
1. Data Processed
a. Analog computer
Used to process qualitative data, working continuously and parallel. Usually, it does not require an intermediate language. For example, computers are used to measure temperature, speed of sound, and power voltage.
b. Digital computer
Used to process quantitative data. For example, letters, numbers, letters and numbers, and special characters. Usually, it requires an intermediate language. one of which is a PC computer.
c. Hybrid computer
A combination of analog and digital computers. For example, fax.
2. Computer Use
a. Computers for Special Purposes (special purpose computer)
A used computer used exclusively and has one function. For example as a server, PC router, or a dumb terminal.
b. Computer for General Purpose (general purpose computer)
General use, such as for graphics processing, multimedia processing, database processing, and processing of other programs.
3. Generation
Computer divided into several generations as follows:
a. The first generation of computers (1946-1959)
b. Computer second generation (1959-1964)
c. The third-generation computers (1964-1970)
d. The fourth-generation computers (1970-1979)
e. Computer fifth generation (1979-present)
f. Sixth generation computer (now)
4. Shape and Size
a. Supercomputer
Type the computer is used to solve problems that require very complex calculations. Because the shape and relatively expensive, this computer is very rare to encounter. Typically, it is used in universities, government, and large corporations.
b. Mainframe Computer
Is a type of computer that is used in environments when users need access to run the program, and put the data together. Usually, this kind of computer is widely used as e-commerce servers that serve transactions over the Internet.
c. Mini Computer
This type of computer is smaller than the Computer Mainframe, but larger than the type of microcomputer. Typically, having multiple terminals. This type of computer is used as a network server computers or internet server.
d. Computer workstation
Single-user computer (used by one person) that is very powerful. Typically, it is used for applications that require complex calculations and heavy jobs, such as the manufacture of computer animation.
e. Micro Computer
The type of personal computer used by one person, whose performance depends on the needs. This includes the type of computer Desktop Computer, Laptop, laptop, and PDA.
