Course Overview


Network, a kind of protocol without which we cannot imagine the way we are communicating/interacting between machines and between people through machines. Sometimes being a curious person, we have also wondered about, how the email we are sending to a particular person reaches to the same person, how machines are mature enough that they are able to function with integrity (not includes machines which are intentionally vulnerable), whether the network we are using is secure or not and such other how’s keep surrounding our mind. At this point, Network Fundamentals – The Technical View of Interaction with Machines will come into picture.

Here, in this course, candidates will learn about –

  • network, networking concepts and its terminologies
  • interaction between two computer systems
  • types of networks and network topologies
  • IP Address as a whole
  • Network Address Translation (NAT)
  • Domain Name System (DNS)
  • Basics on Ports and OSI & TCP/IP Model
