OBJECTIVE
Subject: Data Communication and Computer Networks Branch: III-CSE(A & B) Academic Year: 2011-2012 Semester: I Faculty: K. Archana
The main objective of this subject is introducing the concepts of electronic communications systems, data communications, and network. It also introduces the wireless and wire link telecommunications systems, basic data communications network and systems, local area networks, internetwork and intranetwork. And also includes the protocols like TCP/IP. And it also introducing about the telephone instruments and signals and cellular telephone concepts and cellular telephonic systems. By studying this subject will known about the transmission media and communication cables to transfer the data from source to destination trough signals. And we will know about the communication codes and error controls and data formats for identifying the errors.
