Basic Knowledge Of The Computer Part 1

The computer 

is a tool that is used to process data according to the procedures that have been formulated. The computer was originally used to describe people who perform arithmetic calculations, its work with or without a hearing aid, but the meaning of the word is then transferred to the machine itself. Origin, information processing is almost exclusively associated with the problem of arithmetic, but modern computers are used for many tasks that are not related to mathematics.

In a sense like that there are tools like a slide rule, a type of mechanical calculators ranging from honest and so on, until all the contemporary electronic computers. The term is better suited to a broader sense such as "computer" is "the processing of information" or "information processing system". Over the years there have been several different meanings of the word "computer", and a few different words are now called referred to as computer.
The word computer in General never used for the main person who does arithmetic calculations, with or without auxiliary engines. According to the Barnhart Concise Dictionary of Etymology, the word is used in the United Kingdom in the year 1646 as the word for "people count" then Eve 1897 is also used as a "mechanical" calculators. During World War II these words refer to the United States and United Kingdom women workers who work the street war with artillery count totalizer.
Charles Babbage designed one of the first calculating machine called the analitikal machine. In addition, a wide range of machine tool is as simple as a slide rule also already be described as computers.

Type 

However, the above definition includes a lot of special tools which can only take into account one or more functions. When considering modern computers, their most important properties that differentiate them from the earlier counting tool is that, with the right programming, all computers can emulate any properties (though perhaps limited by the storage capacity and different speeds), and, it is believed that the machine can now emulate the computing tools which we will create in the future (although undoubtedly more slowly). In a sense, limits this ability is a useful test for recognizing "public purpose" computer of special purpose tools early. The definition of "public purpose" can be formulated in terms that a machine should be able to emulate the Turing machine is universal. Machine that got this definition is known as the Turing-complete, and the first one they show up in the 1940s amid a flurry of developments around the world. See the article history of the computing world for more details of this period.

Embedded computer

In about 20 years, many household tools, specifically including the panel of video games but also include mobile phones, video cassette recorders, PDAs and many in the automotive, industrial, household, and other electronic devices, all containing electronic circuit is like a computer that meets the Turing-complete (with a note that the program of the tool is often made directly inside the chipROM will need to be replaced to change the program of the machine). Other special purpose computer in General is known as a "microcontroller" or "embedded computing" (embedded computer). 

Therefore, many limit the definition of the computer tools that mean anyway is information processing, rather than being part of a larger system such as telephones, microwave ovens, or aircraft, and may be modified for various purposes by the user without modification of the physical. Main frame computers, minicomputer and personal computer (PC) is the main kind of computer that got this definition.
