A modern electronic computer is a machine that is meant for ____________.
A modern electronic computer is a machine that is meant for Input, storage, manipulation and outputting of data.
a computer system requires four main aspects of data handling: input, processing, output, and storage. The hardware responsible for these four areas operates as follows:
Input devices accept data in a form that the computer can use; they then send the data to the processing unit.
The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want. The central processing unit executes computer instructions that are specified in the program.
Output devices show people the processed data-information in a form that they can use.
Storage usually means secondary storage. Secondary storage consists of devices, such as diskettes, which can store data and programs outside the computer itself. These devices supplement the computer's memory, which, as we will see, can hold data and programs only temporarily.
