Our Computer Communication Networks MSc provides exposure to the wide variety of technical, managerial and organisational issues essential to effective. Data communication refers to the transmission of the digital data between two or more computers The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. Further computer communication networks are grouped into three categories based on technology and communication media used, namely, (i) Public Switched.

CS402: Computer Communications and Networks

Covers the needs to identify and resolve design issues with regards to networks and protocols. Provides network strategies and regulation policies. Considers how to design and manage networks of different types with computer communication networks to performance and requirements.


This effort, at the University of Hawaii, led to new mobile packet radio ideas and also to the design of the now-famous Ethernet. The Ethernet concept arose when a researcher from Xerox PARC spent a sabbatical period at the University of Hawaii and had the insight that the random computer communication networks radio system could be operated on a coaxial cable, but at data rates thousands of computer communication networks faster than could then be supported over the air.


Ethernet has become a cornerstone of the multi-billion dollar local area network industry. The satellite effort, in particular, computer communication networks international involvement from participants in the UK, Norway, and later Italy and Germany.

The Internet Protocols Another DARPA effort of the early s involved research at Stanford to computer communication networks a new set of computer communication protocols that would allow multiple packet networks to be interconnected in a flexible and dynamic way.

In defense settings, circumstances often prevented detailed planning for communication system deployment, and a dynamic, packet-oriented, multiple-network design provided the basis for a highly robust and flexible computer communication networks to support command-and-control applications.

Transmission Control Protocol and Internet Protocol. The roles of DARPA and the Defense Communications Agency were critical both in supplying sustained funding for implementing the protocols on various computers and operating systems and for the persistent and determined application of the new protocols to real needs.

This effort culminated in a switch to the new protocols in January Thus, the beginning of the s marked the expansion of U. NSF's interest in high-bandwidth computer communication networks was ignited in after the start of the Supercomputer Centers program.

Then-Senator Gore's legislation calling for the interconnection of the Centers using fiber optic technology ultimately led the administration to respond with the High Performance Computing and Communications HPCC Initiative.


The application layer is where all network processes and applications run. We will explore five of this layer's prominent applications: Computer communication networks, we will discuss socket programming and how it can be used to develop network applications.

Completing this unit should take you approximately 20 hours. Each application relies on the transport layer that is described in this unit.

Networking and Communication

It is a key layer in today's networks as it contains all the mechanisms necessary to computer communication networks a reliable delivery of data over any unreliable network. Servers provide access to network resources to all the users of the network. There are computer communication networks different kinds of servers, and one server can provide several functions.

For example, there are file servers, print servers, mail servers, communication servers, database servers, print servers, fax servers and web servers, to name a few.

Computer Communication Networks

Clients - Clients are computers that access and use the network and shared network resources. Computer communication networks computers are basically the customers users of the network, as they request and receive services from the servers.

The most striking example of an overlay network is the Internet itself. The Internet itself was initially built as an overlay on the telephone network.

Computer network

Address resolution and routing are the means that allow mapping of a fully connected IP overlay network to its underlying network. Another example of an overlay network is a distributed hash tablewhich maps keys to nodes in the network.

In this case, the underlying network is an IP network, and the overlay computer communication networks is a table actually a map indexed by keys.
