As a first step toward understanding and learning to use computers, this section give you a peek at these fascinating machines. You will learn about the types of hardware that all computer system use, as well as the types of software that make run. You also will see that without a user someone like you a computer system is not really complete.
Introduction To Computing
Computer
Computer Is An Electronic Device Which Is Use To
Process Data And
Make It Meaningful. Now A Days Computer Is Use In Every Field Of Life.
How Many Parts Of Computer!!
A Complete Computer System Consists Of
Four Parts:
Hardware: Software:
Data: Users(One or More):
Hardware
The physical devices that make up the computer are called hardware. Hardware is any part of the computer you can touch. A computer's hardware consists of inter-connected electronic devices that you can use to control the computer's operation, input, and output. Software
Software is a set of instructionsthat makes the computer able
to perform tasks. In other
words, software tells the
computer what to do.
Software are of two types.
System Software
&
Application Software
Users
People are the computer operators,
also known as users. It can be
argued that some computer system
are complete without person's
involvement; however, no computer
is totally autonomous. Even if
a computer can do its job without
a person sitting in front of it,
people still design, build, program,
and repair computer systems.
Data
Data consists of individual facts
or bits of information, which by
themselves may not make much
sense to a person. The computer
reads and stores data of all kinds
weather words, numbers, images,
or sounds in the form of numbers.
Consequently, computerized data
is digital, meaning that it has been
reduced to digits, or numbers.
