KTU COMPUTER NETWORKS Notes | CST 303 2019 Scheme Notes

COMPUTER NETWORKS CST 303 is a KTU S5 CSE course. This 2019 scheme course note is about the working of computer networks in computer science You can't get computing without networking. This chapter explores the technologies that provide the foundation-and link together-our modern computer networks.

It is important to have a solid computer network system. It can be difficult to select the right computer network, especially when you have a large family. Finding the right computer network is a very important decision that can affect any business success. It is not always easy to determine what computers are fast enough and large enough to handle important information and large graphics. You can learn KTU subjects through our excellent study materials comprising of Notes, Presentations and Previous Years Question papers which are easily available on our website (www.keralanotes.com).

KTU S5 COMPUTER NETWORKS |  CST 303 | Notes (2019 Scheme)

The study of this course provides the learners with a clear understanding of how computer
networks from local area networks to the massive and global Internet are built, how they allow
computers to share information and communicate with one another. This course covers the
physical aspects of computer networks, layers of OSI Reference Model, and inter-networking.
The course helps the learners to compare and analyze the existing network technologies and
choose a suitable network design for a given system.
