Introduction
In the early days of networking, networking bundle was created in haphazard fashion. When networks grew in popularity, the need to standardize the by-products of network software and hardware became evident. Standardization allows vendors to create hardware and software systems that bed communicate with one another, even if the underlying architecture is dissimilar. For example, you give the axe run TCP/IP protocol to access the profits on an IBM-compatible PC running Windows or an Apple macintosh running OS X.

Describe the OSI model and how it relates to networks. Specify the master(prenominal) features of 802.2 LLC and MAC. Identify the purpose, features, and functions of hubs, switches, bridges, routers, gateways, and network interface cards. Given an example, identify a MAC address.
Identify 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.
