What is the function of input devices?
The main function of input devices is to direct commands and data into computers. Computers then use their CPU to process this data and produce output. For example, a laptop’s keyboard is an input unit that enters numbers and characters. Similarly, even a mouse can be an input unit for entering directions and commands.
What is the function of a control unit?
It is responsible for coordinating tasks between all components of a computer system. The control unit collects data from input units and sends it to processing units depending on its nature. Finally, it also further transmits processed data to output units for users.
Where does the data stored in a computer stay?
Once a user enters data using input devices, the computer system stores this data in its memory unit. This data will now remain here until other components of CPU process it. The memory unit uses a set of pre-programmed instructions to further transmit this data to other parts of the CPU.
Can a computer function without these elements?
No computer can function in the absence of these elements. Apart from these elements, a computer system comprises of three basic components. These components are responsible for making computers actually function. Let’s take a look at them in detail.
What are the components of a computer?
The four main components of computer system are input devices, output devices, Memory and Central Processing Unit (CPU). Input devices are used to provide input and instructions to be processed to the computer.
What are the output devices of a computer?
These devices are also called peripheral devices and include mouse, keyboard, microphone, scanner etc. Output devices include monitor and printers which are used for displaying the results of the instructions processed by the computer. CPU (Central Processing Unit) is the main component of the computer which is responsible for data processing.
What is the purpose of CPU?
CPU uses memory (another important component of computer) to store the instructions either permanently or temporarily. Memory then has further types such as RAM, ROM and secondary storage devices. All these components work together to perform the various commands given by the user. 1.
