Modern information technologies

Information technology - it mashynizovani methods of storage, handling, transfer, use the information in the form of knowledge. They include two main components - hardware and man, the latter of which is the main thing.

The foundation of modern information technology are three main technical advances :

The emergence of a new medium accumulation of information on physical media ( magnetic tapes , microfilm , magnetic and optical disks, semiconductor devices, etc.);

Development of communication facilities that provide delivery information virtually anywhere in the world without restrictions in time and space , and mass outreach communications (radio, television, data network , satellite, telephone network )

Possibility of automatic data processing by computer according to a given algorithm.

The main tasks of modern information technologies are:
achieve universality methods of communication;
support of Multimedia
maximum simplification means of communication in the "human-computer".

The basic properties of information technology are:
• The feasibility.
• The availability of components and their structure.
• Interaction with the environment.
• Integrity.
• The development in time.
