Computer means an electronic calculator that can perform calculations according to a set of values and compare the results ordered by high speed continuously and automatically. Royal Institute dictionary,2525 (1982)., definition of a computer is quite compact, automated electronic machines that act like mechanical brains. Used for various solutions, both simple and complex mathematical methods or by other. A tool that helps in the calculation and processing of data from the properties of a computer, not a calculator. A computer contains three properties:
1. speed (Speed), the computer can work with a very high speed, the speed of the computer measure
- Michelle lali se. (Millisecond) that compares the speed is equal to 1/1000 second or seconds.
. -Micro-se. (Microsecond), which matches the speed is equal to 1/1000000 sec or sec
- Nano-se. (Nanosecond), which compares the speed is equal to 1/1000000000 seconds or seconds.
. Different speed depending on the properties of the computer era, which have developed more powerful computers. Using computer data processing speed at no more than 1 second. 2. memory (Memory) consists of computer memory that can be used to record and store
. Data in large increments, and can store commands (Instructions) so that programs that are processed at the same time, which causes the computer to be able to work at a time, storage room, such as a demographic survey. From that memory can save programs and data locally. Make your computer a special property is that it can be run automatically. Accurate and economical due to write a single command can be run repeatedly each time it reached
.3. The ability to compare (Logical) And this one makes it possible for developers to create computer programs more widely available. Like to arrange the information, you need to use the method of comparison. To run repeatedly according to the set criteria. And the use of labor from the computer instead of labor from human fast properly. An precision and lessen human very seriously.
