DEFINITION COMPUTER

The term computer has a broad meaning and is different for each person. The term computer (computer) is derived from the Latin meaning computare count (to compute or to reckon).
According Blissmer (1985), the computer is an electronic device that can perform several tasks, namely to accept input, process the input in accordance with the instructions, keep the commandments and processing results, and providesputt in the form of information.
Meanwhile, according to Sanders (1985), the computer is an electronic system to manipulate data quickly and accurately as well designed and organized to automatically receive and store input data, process it, and produce output based on instructions stored in memory. And many more experts are trying to define it differently on the computer. However, in essence it can be concluded that the computer is an electronic device that can receive input, process input, provide information, using a program stored in computer memory, can store programs and processing, and works automatically.
From the definition, there are three important terms, the input (data), data processing, and information (output). Data processing using a computer is known as electronic data processing (PDE) or elecronic data processing (EDP). Data is a collection of events that removed from a fact (fact), can be numbers, letters, special symbols, or a combination of all three. Data still can not tell much that needs to be processed further.
Data processing is a process of manipulation of the data into a form that is more useful and more means, ie in the form of information. Thus, information is the result of a data processing activities that provide a more meaningful form of a fact. Therefore, electronic data processing is the process of manipulation of data into a more meaningful form of an information by using an electronic device, namely a computer.
