Hardware Components
There are four basic functions that a computer can perform, data processing, data storage, data movement
and control.
In data processing, the data are in various form thus the
processing also is broad however there are few fundamental methods or types of
data processing available. In the data storage, the computer stores some data
that actively work at given time which is short-term data storage function.
The
computer also performed the long-term storage function for file storage, update
and retrieval. The computer requires devices which able to move the data from
sources to destinations.
Process of data receiving or delivering is known as
input-output and the device is known as peripheral. Data also can be moved
remotely through data communication process.
Lastly, the control unit manages
the computer’s resources and monitor the performance when response to
instructions.
The structure of computer can be categorized
into two categories;
- simples-single processor computer
- multicore
computer structure.
The traditional simple-single processor
computer has fours components; control unit, arithmetic and logic unit (ALU),
registers and CPU interconnection. The multicore computer structure is for
contemporary computers.
The processors are in a single chip or known as
multicore computer. Each processing unit consists of control unit. ALU. registers
and cache which called core.
