Functions of computer
Both the structure and functioning of a computer area unit are, in essence, simple. normally terms, there are only four basic functions that a laptop will perform:
Data processing:
information could take a large sort of form, and therefore the variety of process requirements are broad. However, we tend to shall see that their area unit solely some elementary ways or types of processing.
Data storage:
notwithstanding the pc is process information on the fly (i.e., information are available and find processed, and therefore the results leave immediately), the pc should briefly store a minimum of those pieces of knowledge that area unit is being worked on at any given moment. Thus, there's a minimum of short data storage operations. Equally necessary, the pc performs long information storage operate. Files of knowledge area unit keep on the pc for sequent retrieval and update.
Data movement:
The computer’s operative surroundings consist of devices that function as either sources or destinations of knowledge. once the information area unit is received from or delivered to a tool that is directly connected to the pc, the method is thought of as input-output (I/O), and therefore the device is referred to as a peripheral. once information area unit stirred over longer distances, to or from an overseas the device, the method is thought of as information communications.
Control:
Among the pc, an impression unit manages the computer’s resources and orchestrates
the performance of its useful elements in response to directions.
