Information is the systematically stored data in your devices or computer and Information technology is the technology which is used to secure, transmit, retrieve your data or information. It is also called IT, Infotech, Cybernetics. IT plays a very crucial role in various commercial sites or you can say in various sectors of life such as in education, at homes, in businesses, etc. Infotech is a subgroup of information & communication technology (ICT). In simple words, you can say that information & communication technology is a technology to boost your business as it has been designed to support the maintenance, growth, development of the business. But all these cannot be possible without the use of devices and the person who will work on these devices.
So, there are many types of cybernetic technologies including software & services which are designed for different fields according to the need of their environment.
Examples of information technology are:
- Most common used IT is Computers & Computer networks
Other words or Synonyms for Information technology
- Data processing;
- Computerized information;
- ICT (information & communication technology);
- Information science;
- Electronic data processing; etc.
Types of Information technology
(1) Technical support
Technical support means to troubleshoot the problems. The person who are specified for this job are called problem managers/technical support officers as they satisfied their clients by providing technical support to them. In simple words, you can say that technical support officer issues the solutions to solve the hardware as well as software problems.

The computers are unable to do things on their own and they can work according to the instructions given to them by the users. So, their working depends upon the instructions and these instructions are called programs. The person who writes or designed programs are called programmers. The computer programmers first write and then test the code which comes to us in the form of a software.
Types of programs
- System programs
- Application programs
The programs which manage the hardware resources are called system programs whereas the programs used to perform specific tasks such as web browser, music player, video player are known as application programs.
There are different types of Programming languages
- Machine language (binary language: using only two digits 0, 1).
- Assembly level language
As we all know that a computer is a machine and it can only understand the binary language. The instructions or programs are given to the computer must be written in the form of binary language and this language is quite difficult to understand but the computer executes the programs if they are written in the machine language. So, the user writes the code in the assembly level language as it easy to understand or you can say in the user-friendly language but the computer could not understand this language, hence it will not execute the program. So, there a special program is required to convert this language into computer understandable language. The program which is used to convert the assembly level language into machine level language is known as Assembler. After converting the assemble level language into machine language computer will execute your program very fast.
It is a collection of electronic resources, is very important to run the internet. Internet cannot be run without the use of a web which means “No Web No Internet”.
