Information technology (IT) is a process of development, implementation, & maintenance of computers and telecommunication resources to receive, store, access, interpret & communicate data or information through electronic means. Uses of information technology are in business, agriculture, health, education, etc.
Definition of Information Technology
Information technology (IT) makes use of computers to process, store, recover and broadcast information with fast communication links and channels from one place to another in a networking environment. The interconnection of the computer enables people to send and accept information.
The communication links also are used to collaborate with different people in the world. It is important to know that Computer is a central part of IT. It makes doable to use IT for solving troubles. It has become feasible due to fast communication links.
Nowadays the world has become a global community due to improvement in information technology. It means that people living in a world known one another as if they are living in a village. Everyone can transfer information from one place to another place simply and also very fastly.
Furthermore, Information technology has enabled diverse types of institutions and organizations to be an element of digital conversions. The digital conversion means that industries have combined electronically to swap information. These industries contain a computer, telecommunication and mass data, etc.
This merging has a deep effect on the up to date world. The information can be communicated in any form such as photographs, movies, audio, graphical shapes, text, and digital diagrams, etc.uses of information technology are in the field of education, agriculture, health business, etc.
Components of Information Technology
Information technology (IT) makes use of computers to process, store, recover and broadcast information with fast communication links and channels from one place to another in a networking environment. Components of IT are computers, software, hardware, communication network, & know-how.
Important components of Information Technology are as follows:
- Communication Network
A computer is a programmable electronic device that evaluates data according to a set of commands, produce output as a result and store it for future use. A computer is controlled by programmed instructions. It performs four general operations i.e input, processing, output, and storage.
Software is a set of computer instructions that directs a computer, how to interacts with the user and to process the user’s data. It includes libraries, programs, and non-executable data, that directs all the peripheral devices on the entire computer system, what exactly to do and how to perform.
It is a well-defined set of commands and instructions that tells a computer what to perform. A computer works as per given instructions in the software. It is stored and loaded from the hard disk into the main memory of the computer when required.
The physical parts of the computer like system unit, keyboard, monitor, mouse, and speakers are called hardware. Hardware can be seen and touched. If any hardware component of the computer can be damaged or destroyed, it can be replaced but not installed.
4: Communication Network
A communication network is an interconnection of diverse locations through a medium that enables people to send and receive information. It permits people and businesses to cooperate. It includes hardware, programs, and information. IT has become revolutionary through the use of communication networks.
know-how is the capability to do something properly. IT know-how consists of familiarity with the tools of information including the internet, possession of the skills needed to use these tools and understanding of using information technology for problem-solving and creating opportunities.
Furthermore, it is important that people should know the use of IT to solve problems. They should also know how information technology can create opportunities for them.
