What is a computer Hardware?
A computer hardware is the hard part of the computer that can be seen, touched and carried about. It works hand in hand with the software and also the userware.
Computer hardware groups.
The following are groups of hardware components in the computer. They are;
-Input device
-Output device
-Processing device
-Storage device
-Communication device.
Input device.
Input device are those device that can be used to send data into the computer. Examples of input device are; mouse , keyboard, light pen and joystick.
Data is entered to the computer via the input unit. The input unit with the aid of input device helps to take in data to the computer.
Output device.
Output device are those devices that can be used to view the results of processed data. Examples of output device are monitor, projector, and speakers.
With the output device, you will be able to view the result of the input data which is also classified as information. It is easily viewed using the output device.
Processing device.
Processing device such as the system unit helps to process the input the computer was given alongside with the command to carry out task.
Example of processing device is the system unit. The system unit is the mains of the computer.
I spent sometime to discuss only the system unit in details which you can also check on my blog.
Storage device.
Storage device are device used to store information such as resources, files or folders. There are two types of storage which are temporary and permanent storage.
Example of storage device include hardisk, CDrom, RAM, cache.
Communication device.
Communication device are those device that can be used to communicate over the internet with other users of the computer.
Examples of those devices includes a modem, wifi.
Input device carries in data to the computer with the aid of input device. The data is then been processed and understood by the system. The processed data is also stored according to the user wish. The data can as well be displayed on the screen with the aid of output device. In a bid to foster the communication process between systems, a communication device is used.
Conclusively.
Hardware groups and thier importance or contribution to the system bas a whole.
