A Computer is an electronic programmable device that accepts data and instructions, processes them according to instructions and produces output as information.
A computer is an device that manipulates information, or
data. it's the flexibility to store, retrieve, and process data. you will
already know that you simply can use a computer to type documents, send email,
play games, and browse the online. you'll be able to also use it to edit or
create spreadsheets, presentations, and even videos.
The "computer" is an ensemble of various machines that you simply are going to be using to urge your job done. A computer is primarily manufactured from the Central Processing Unit (usually said the computer), the monitor, the keyboard, and therefore the mouse. Other pieces of hardware are commonly observed as peripherals.
In way of life activities, we process data or encounter cases of knowledge processing. A typical example of data processing is that the generation of statement of student result from the marks score in an examination and continuous assessment. it's essential to understand that information is pretty much as good because the data from which it's derived, and therefore the transformation process which they're subjected to. Meaningless data or inappropriate processing produces wrong information. Thus computer gives you results such as what data you supply and the way you process it (i.e. garbage-in, garbage-out).
Summarily, the intelligent performance of a computer depends on correctness of computer file and therefore the intelligence performance of the creature that drives it.
How computer works?
Every computer perform it's tasks in three steps.
- accept the data and instruction given by the user.(i.e input)
- Process the data according to the given set of instruction i.e it responds to specific set of instructions in a well-defined manner. It can execute a prerecorded list of instructions(i.e Processing)
- Store and give information according to the requirement of the user(i.e output ).
