What is computer
A computer is an electronic device which processes raw data under program to generate the meaningful information the computer is made up of combination of electronic and electromechanical component.
Data collection of facts figure statistics which can be proceed to produce meaningful information.
Characteristic of computers
A computer is generally used due to the following attributes.
1. Speed
A computer can work very fast .It can perform in minutes/ second the task that would take a person long time to complete.
2. Accuracy
A computer always gives accurate result.
3. Reliability
Computer consistently provide the same accurate result under all operating conditions.
4. Storage capacity
A computer can store large amount of data.
5. Deligence
Computer can keep on working for long hours and never gets tired.
What is digital computer
It is digital system which perform various computational tasks.
Digital computers use binary number system which have to digital example 0 and 1 .
A binary digit is called bit . Information in digital computer or in groups of bits.
They can store different sets of instruction and programs. These are mainly used for business
What is the analogue computer
Analogue computer are computer that measure physical quantity .
example .
pressure, temperature, length etc and convert them to numeric value analogue computer are used mainly for scientific and engineering purpose because there with quantities.
What is input and output devices in a computer
The input and output devices provides the means of communication between the computer and the outer world.
Input device
An input device is an electromechanical device, which accept data from the outside world and translate them into a form who is the computer can interpret .Some input device are.
1. Keyword
They allow data entry into a computer system by by pressing a set of a key .
Which is contacted the computer system.
2. Mouse
It is small device which can comfortably fit in users palm.When user scroll the mouse across a flat surface the graphical on the monitor screen in the direction of the mouse movement. When we place the mouse on a particular them and click the mouse, the system then notify the particular choice.
3. Image scanner
It translate the paper document into an electronic format
which can be stored in a computer .The input document graphics or even handwriting material
Output devices
It is also electromechanical device which accept data from a computer and translate them into a from ,which is suitable from used by the outside world. Output device can be classified into the following two types.
1. Soft copy
The output which is not produced on a paper are some material
This output cannot be touched.
2. Hard copy
It is produced on paper or some material which can be touched and carried any where.
They are parmanent in nature and can be kept in paper file.
It can be read, when the person is not using the computer.
3. Monitor
Monitor display the generated output on a screen.A a monitor is usually associated with keyword and together they from a video display terminal (VDT).
VDT(video display terminal) servers as both an input and an output devices.The two basis type of a Monitor used today are cathode Ray tube (CRT) and flat panel.
4. ЁЯЦи️ Printer
Printer used to produce hard copy.
