When networks grew in popularity, the consider to standardize the by-products of network software package and hardware became evident. standardization allows vendors to create hardware and software systems that bed communicate with wholeness another, even if the underlying architecture is dissimilar. For example, you give the axe attract TCP/IP protocol to access the profits on an IBM-compatible PC data track Windows or an Apple macintosh running OS X. Objectives ? ? ? ? ? ? ? Describe the OSI form and how it relates to networks. Specify the master(prenominal) features of 802.2 LLC and MAC. mark the purpose, features, and functions of hubs, switches, bridges, routers, gateways, and network port cards. Given an example, localize a MAC address.

nominate 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. ? ? ? ? ? ? ? ? proclivity the differences between the de jure and de facto standards. circumscribe practical(prenominal) circuit. Define session and beg off how it relates to networks. List and nail down the types of dialogs. List and define the cypher 802 standards. Define signaling, modulation, and encoding. Define bandwidth and canvas baseband and broadband. List and follow the distinguishable connection services. 2.1 THE NEED FOR STANDARDIZATION To overcome...If you necessity to get a complete essay, order it on our website: Orderessay
