The number of computer networks is increasing dramatically. From small offices to entire countries, computer networks have become the heart of electronic communication today. Using established protocols, these local and wide area networks have become the conduit for servers and clients. Of interest today is data integrity and security as well as the “right” to the information communicated
Identify some contributors to networks and relate their achievements to the knowledge area; identify some components of a network; name some network devices and describe their purpose; describe advantages of a star topology over a ring topology; describe advantages of a ring topology over a star topology; define the meaning of a protocol; explain the importance of security when dealing with networks; and describe how computer engineering uses or benefits from networks.· Understand fundamental concepts of networks and their topologies; and understand the concept of network architecture and its hardware components.· Demonstrate understanding of the elements of a protocol, and the concept of layering; recognize the importance of networking standards, and their regulatory committees; describe the seven layers of the OSI model; compare and contrast the OSI model with the TCP/IP model; and demonstrate understanding of the differences between circuit switching and packet switching.· Understand the basic concepts of LAN and WAN technologies and topologies; demonstrate understanding of different components and requirements of network protocols; demonstrate understanding of basic concepts of error detection and correction at the data link layer and below; and design and build a simple network by implementing (and designing) a simple network protocol that operates at the physical and data link layers of the OSI model.
