incrementing bandwidth requisites of LANs; the ever evolving technology of LAN wire is hardly the “telephone wire” that the majority think of it as. Below is a chart showing the LANs growth in capacity LAN | Bandwidth | Ethernet | 10 Mb/s | FDDI | 100 Mb/s | Fast Ethernet | 100 Mb/s | ATM | 55, 155 Mb/s | Gigabit Ethernet | 1,000 Mb/s (1 gigabit/s) | 10 Gigabit Ethernet | 10 Gb/s | But still, even with all the efforts that copper cabling manufactures have made to stay relevant

speed of data exchange. MANs ensure economic and efficient connection of LANs providing them accesses to WANs. The most important stage in the evolution of computer network was the arrival of standard networking technologies. These include Ethernet. FDDI and Token ring these technologies allow different types of computers to connect quickly and efficiently. During 1980s LANs and WANs were characterized by significant

3.1.2 Types of Computer Networks Computer networks are classified based on the geographical length. A network can be as small as the distance between a mobile phone and its Bluetooth headphone. Also it can be as large as the internet itself. It covers the whole geographical world. Types of Networks • LAN • WAN • MAN (i) LAN (Local Area Network) A local area network is a self-contained network. It lengths a small area, such as a single building, floor, or a room. In LAN, all the nodes and segments

electromagnetic interference. There are two main TPC industry standards Twisted Pair (UTP) and Shielded Twisted Pair (STP) , newer Ethernet Cables use UTP due to their low costs, whilst STP cabling could be found in some types of networks for instance FDDI. • Fiber Optic- Fiber Optic cables contain strands of glass fibers inside insulated casing. These cables where created for long distances and high bandwidth network .communications. Software- Software used in a network is created to help set up,

Assignment: VLAN IT/242 January 19, 2012 Instructor: Dr. Jimmie Flores Assignment: VLAN VLAN short for Virtual Local Area Network is a new LAN technology that allows addition of a cost effective network that does not compromise security or performance of the network. VLAN is defined as “a switched network that is logically segmented on an organizational basis; either by functions, project teams, or applications rather than on a physical or geographical basis” (Regan, (2004))

VLAN Configuration This chapter describes how to configure normal-range VLANs (VLAN IDs 1 to 1005) and extended-range VLANs (VLAN IDs 1006 to 4094) on the CGR 2010 ESM. It includes information about VLAN membership modes, VLAN configuration modes, VLAN trunks, and dynamic VLAN assignment from a VLAN Membership Policy Server (VMPS). Note For complete syntax and usage information for the commands used in this chapter, see the online Cisco IOS Interface Command Reference, Release 12.2. * Understanding
