INFORMATION TECHNOLOGY

 Now, I am going to introduce you What is Information Technology ? the concepts of IT and a little explanation about the differentiation  between IT and ICT.

     
    Information technology (IT) can be defined in various ways, but is broadly considered to encompass the use of computers and telecommunications equipment to store, retrieve, transmit and manipulate data. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones.

One of the major activities associated with producing an IT Architecture will be the process of achieving such consensus decisions. It is understood that reaching consensus may constrain purchase and design options, hopefully in the interest of enhancing interoperability. It is a given that the greater the consensus achieved, the greater the organizational benefits attained.

     IT Infrastructure  is the physical hardware used to interconnect computers and users. Infrastructure includes the transmission media, including telephone lines, cable television lines, and satellites and antennas, and also the routers, aggregators, repeaters, and other devices that control transmission paths. Infrastructure also includes the software used to send, receive, and manage the signals that are transmitted.
