What Is a Computer?

What Is a Computer?? Want Tau Definition or Definition Computer ?? Let's look at the bottom of this article:

According Blissmer (1985), computer adalahsuatu electronic device that can perform several tasks, which receive input, process the input according to the instructions given, save the commands and its products, and provides output in the form of information.

Meanwhile, according to Sanders (1985), a computer is an electronic system to manipulate data quickly and accurately as well as designed and organized in order to automatically receive and store input data, processes it, and produces output according to the instructions that have been stored in memory. And many more experts are trying to define differently about computers. However, in essence, it can be concluded that the computer is an electronic device that can accept input, process the input, provide information, using a program stored in the computer memory, it can store the programs and the results of processing, and works automatically.

From the definition, there are three important terms, namely the input (data), data processing, and information (output). Data processing using a computer known as electronic data processing (EDP) or elecronic of data processing (EDP). Data is a collection of events is lifted from a reality (facts), can be numbers, letters, special symbols, or a combination of all three. Data still not able to tell much that needs to be processed further.

Data processing is a process of manipulation of data into a form that is more useful and more means, in the form of an information. Thus, information is the result of a data processing activities that provide a more meaningful form of a fact. Therefore, the 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.

According to the Annual Computer (Robert H.Blissmer), a computer is an electronic device that can perform several tasks as follows:

receive input

Process input earlier in accordance with its program

Storing commands and the results of processing

Provide output in the form of information

According to the book Computer Today (Donald H.Sanders), a computer is an electronic system to manipulate data quickly and accurately as well as designed and organized in order to automatically receive and store input data, processes it, and produces output under the supervision of a step-by-step instructions that program stored in memory (stored program).

According to the book Computer Organization (VC Hamacher, ZG Vranesic. SG Zaky), the computer is a fast electronic calculating machine that can receive digital input information, process it in accordance with a program stored in memory (stored program) and generate output information.

According to the book Introduction To The Computer, The Tool Of Busines (William M.Fouri), a computer is a data processing (data processor) that can perform large calculations and fast, including large arithmetic or logic operations, without intervention from humans operate during processing.

According to the book Introduction to Computers (Gordon B. Davis), a special type of computer is a counter that has a definite certain properties.

From the definition obtained from a variety of books, it can be concluded that the computer is:

electronic equipment

Can receive data input

Can process data

Can provide information

Using a program stored in the computer's memory (stored program)

Can store programs and processing results

Work automatically

While the so-called program is a detailed set of instructions or orders which has been prepared so that the computer can perform its functions in a way that is certain.

Along with the development in technology it is possible that Definition The computer itself will change according to the context later. Interested about the computer buddy can also read the history of Computer and understanding of computer hardware.
