INTRODUCTION OF INFORMATION TECHNOLOGY
Through
information technology consist of two words and a single term but it encloses
in itself a vast measuring relating to any country’s development and progress.
Since its an era of computer the introduction of IT has proved to be quit useful. When the field of communication
science was near to decline, another field of computer sciences arose which was
felt beneficial in uprising the level of communication sciences; then they were
being merged into one-another to form a new field called IT (Information Technology). In this
technology computer is being used as a useful tool.
We
are living in an information age, bombarded with loads of information around
us. Information Technology is
the use of science to store, handle, process and transmit information. Rapid
changes are taking place in IT
every movement all over the world. Not too long ago, the telephone was once of
the few means which we can use to communicate with a friend over seas. Today’s,
we have many other choices such as the fax machine and the computer Internet.
DEFINITIONS
J When we learn study
the latest information about the technology which is now a days enhanced to
utilize these information practically and solve the requirement of the casual
person is called as IT.
J Information
Technology is the methods, for using modern technology for storing, processing,
analyzing and communication of information. Modern technology includes big
Networks on which data can process, store and travel from one location to other
location.
J The technology that
mergers computing with high-speed communication links carrying data, sound and
video. The Technology to store, send, receive, process and present the
information is called Information Technology.
J IT is the mergers of
two Sciences, i.e. Computer Sciences
& High-speed Communication Sciences.
COMPUTER SCIENCES
The field of study that deals with the
structure and operations of computer systems. The study of computers, including
both Hardware and Software design. Computer Sciences are composed of many board
disciplines, including artificial and software engineering.
COMMUNICATION SCIENCES
The field of study that deals with
the structure and operations of communication system. The external architecture
of a computer involves electronic signals being passed from component to
component. It is a natural extension of this idea to send signals out of the
computer to another computer perhaps thousands of kilometers away.
COMPUTER!
The word “COMPUTER”
comes from the word “COMPUTE”, which means to calculate. Computer was to create
a fast calculating machine. But more than 80% of work done by the computer
today is non-mathematical or non-numerical, because computer work on binary
digits (0s and 1s), 0 means off and 1 means on.
WHAT IS COMPUTER
A
computer is an electronic, data processing device that
Receive
the data; that we feed into it (INPUT) Process
the data; according to our instructions (PROCESSING) Give
the result; (OUTPUT) Store
the data, inside it (MEMORY).
DEFINITION OF COMPUTER
Computer is an
automatic electronic data processing device, which can process the data under
given commands, ability to remember information and also give the result.
Computer accept the data process it generate the result (give out put) and able
to store it. Computer is an electronic machine can calculate a specific result
according to our given instructions. According to above definitions of computer
it is observed that computer cannot perform any thing with out any
program/software and programmers /soft wares are made human begins. So computer
cannot perform any thing with out instruction on user. It only can dependent
upon user, which type of command user can apply. Some advance computers like
robots perform some thing without any command perform by any human being, but
these type of computer has come special type of software which technology calls
artificial intelligence. A I is such thing in which computer observe thing and
than perform some things according to these observed, actually the software has
ability to perform any thing and decide the which thing can be performed when
any event occur. So we say hat computer perform any thing onto the verbal
instructions of user.
COMPUTER SYSTEM
A
collection reference to all interconnected computing hardware, including
processor, storage devices, input/output devices and communication equipments. Complete
collection of computer components i.e. Hardware, Software, Peripherals, Power
supplies and Communication links; making up a single computer system.
Hardware
The physical parts of
the computer are collectively called its hardware. All the computer mechanism
and parts are called the computer hardware e.g. Keyboard, motherboard, mouse,
modem, monitor, printer etc.
Software
Program of the
computer is called software. All the instruction and data are called computer
software. Without the computer software the computer hardware is unable to do
anything. Computer software makes the computer hardware alive. Operating system
is also software, which is a translator between computer and computer user.
Peripherals
The keyboard and the
printer are attached to the CPU at its periphery (Edges), so they are called
peripherals. The Input/Output (I/O) devices are also called peripherals.
Power Supplies
All the power which
supply inside the computer devices are supplied by the power supply external
power cable attached with power supply and then it change it according to
different and then supply it to devices. So power supply is the controller of
the power inside the computer.
