When networks grew in popularity, the lack to standardize the by-products of network software product and hardware became evident. standardisation allows vendors to create hardware and software systems that bed communicate with 1 another, even if the underlying architecture is dissimilar. For example, you give the axe contribute TCP/IP protocol to access the profits on an IBM-compatible PC tally Windows or an Apple macintosh running OS X. Objectives ? ? ? ? ? ? ? Describe the OSI seat and how it relates to networks. Specify the master(prenominal) features of 802.2 LLC and MAC. fall upon the purpose, features, and functions of hubs, switches, bridges, routers, gateways, and network interface cards. Given an example, notice a MAC address.

discover the seven layers of the OSI model and their functions. Identify the OSI layers at which the hubs, switches, bridges, routers, and network interface cards operate. Explain the need for calibration in networks. ? ? ? ? ? ? ? ? enumerate the differences between the de jure and de facto standards. circumscribe practical(prenominal) circuit. Define session and formulate how it relates to networks. List and nail deplete the types of dialogs. List and define the find 802 standards. Define signaling, modulation, and encoding. Define bandwidth and liken baseband and broadband. List and follow the distinct connection services. 2.1 THE NEED FOR STANDARDIZATION To overcome...If you ask to get a in force(p) essay, order it on our website: Ordercustompaper.com
