Computer Network



The course is intended for
  • For junior programmers who want to gain primary and basic knowledge about networks such as structure, types, operating principles (especially TCP/IP protocol) and high-level software solutions. The course will be important for people who plan to engage in network management, programming, since today the main field of programming works in a network environment, as well as for those who want to increase knowledge on networks.

    • Required knowledge
  • Basic knowledge of computer structure and operation, general experience working with operating systems
  • Knowledge of number systems: binary, octal and hexadecimal
