• Give more exercises with past year question with answer so that the students can check answer by their own.It will be convenient to students if the answer sheets have working on it.So that the students can study by their own if he/she answer is wrong
•   Put more videos about the course as this can make the subject more interesting and this make students enjoy learning it.
• Course schedule should be extended to assimilate contents better.

In 1969-DARPA has supported ARPANET and this allows multiple computers to communicate on one 
              network.
In 1972-Ray Tomlinson who is a Cambridge computer scientist had introduces email with its famous

In 1983-TCP/IP is developed a standard setting model for data transmission between multiple 
              network
In 1992-Internet Society(ISOC) established

Broder access leads to the modern Internert:

In 1994- North American Network operators' Group (NANOG) established.
In 1999 wireless networking
