Operating system

Operating system is the interface between computer and application software packages . Without OS no computer can be operated. For a computer system, it is regarded as the heart of living being . In other world ,the OS is defined as a program or suite of programs that control the entire operation of the computer, such as recognizing input from the keyboard , sending output to the display screen ,keeping track of files and directories on the disk , and controlling peripheral devices such as disk drives and printers etc . The routines , which performed input and output were especially important .Each input and output device had its own characteristics requiring careful programming .A special program routine was written for each input/output (I/O) device.

Information And Technology Management

Information Technology is the study or use of systems such as computers and telecommunications for storing , retrieving and sending information. IT stands for Information Technology.

Tourism

Nepal , a country of full of natural beauty .A number of tourists visit nepal within a year. Tourism is an activity that takes place for leisure or business and stay for at least 24 hours .World Tourism Organization defined tourist as person who travel to and stay in places outside their usual environment for leaisure, business etc . IT helps both tourist and country because it provide information about destination fields , so tourist are really help to make their visits successful.

Science and Technology Research

The development in the fields of science and research has directly linked with the standard lifestyle of people . Science has ovecome different difficulties . Different scientist are doing research for the invention of new technology and they are helped by Information Technology .IT provides necessary information for their research which helps for the fast finding . So, IT indirectly is the main cause for the development and progess of the world.

Computer Technology

Computer is an advanced electronic and programmable device which takes raw data as input from the user then process the data as per given instruction then gives output and stores it for future use. An automatic electronic apparatus of making calculations or controlling operation that are expressible in numerical or logic nature. The computer word is derived from the latin word 'computare' (compute in english) , which means to calculate .The word calculate mean to find out the result of some operation on numeric and non-numeric valves. Computer helps us to do different works like research, file making etc .IT develop the compuer technology and computer technology is developing day by day in a rapid way.

Engineering

Information Technology are spread in different fields and help in the development of respective fields and it is link with engineering too . Engineering are the major subjects that the students choose .These students have to do so many of research and should find different engineering terms . So, IT help them for the research . IT provides information about engineering for the general public.
