Tutor: Adwait Sharma
Computer Network System is semester 5 subject of final year of computer engineering in Mumbai University. Prerequisite for studying this subject are Digital Communication Fundamentals.
Course objective of the subject Computer Network is to introduce concepts and fundamentals of data communication and computer networks. To explore the inter-working of various layers of OSI. To explore the issues and challenges of protocols design while delving into TCP/IP protocol suite. To assess the strengths and weaknesses of various routing algorithms. To understand the transport layer and various application layer protocols. Course Outcomes of the subject Computer On successful completion of course learner will be able to: Demonstrate the concepts of data communication at physical layer and compare ISO – OSI model with TCP/IP model. Demonstrate the knowledge of networking protocols at data link layer. Design the network using IP addressing and subnetting / supernetting schemes. Analyze various routing algorithms and protocols at network layer. Analyze transport layer protocols and congestion control algorithms. Explore protocols at application layer.
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network may include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by hostnames and network addresses. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, for example, the transmission medium used to carry signals, bandwidth, communications protocols to organize network traffic, the network size, the topology, traffic control mechanism, and organizational intent. Computer networks support many applications and services, such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications.
