Computer

The picture above is a kind of super computers used by NASA in Columbia


Computers are electronic devices that can be used to process the data according to procedures that have been formulated. Computer word originally used to describe someone who is doing the work arithmetic calculations, with or without tools, but the meaning of this word and then transferred to the name of the machine itself. Onset, the processing of information is almost exclusively related to arithmetical problems, but modern computers are used to do various tasks that are not related to mathematics.


In the definition there are tools such as slide rule, mechanical calculator types ranging from abacus, and so on, until all contemporary electronic computers. The term computer is better suited for a broad sense as "computer" is "that process information" or "information-processing system."
According to the history of computers, computer generation is divided into 5 parts.


1. Computer
Embedded Computer 1.a
Personal Computer 1.B
2. How to Computer Work
2.A Memory
2.B Processing
2.C Input and Results
2.D Instruction
2.E Architecture
2.F Program
2.F.1 Operating System
3. Computer Use
4. The word "Computer"
5. Computer parts
5.A Hardware
5.B Software
5.C slot on your computer


The above definition includes many special tools that can only take one or several functions. When considering modern computers, the nature of the computer the most distinguished of the tool calculates the earlier is that, with the right programming, any computer can emulate any nature (although limited by storage capacity and different speeds), and, it is believed that the machine now computing devices can mimic what would we create in the future (although more slowly).


In a sense, these limits are a useful test because the computer recognized the "general purpose" of the special purpose equipment early. The definition of "public purpose" can be formulated into a condition that a machine should be able to emulate a universal Turing machine. Machines that have this definition is known as a Turing complete, and the first computers appeared in 1940 in the middle of development throughout the world.
