  2. Contents • Advantages • Disadvantages • Cabled LAN, 3 types • Essential hardware • LAN topologies • 3 structures of topologies • Bibliography

  3. Advantages • Costly hardware can be shared. • Network software is cheaper than purchasing individual packages. • Same files can accessed by all users. • Messages can be sent between clients. • Single internet connection can be shared by clients. BACK

  4. Disadvantages • Expensive to set up and maintain. • Viruses can spread to all computers in the network. • More prone to hacking due to multiple points of access. • If it is a star network, if the file server goes down, the whole network will go down. BACK

  5. 3 types of Cabled LAN Cabled LAN is not wireless, but requires wires. • Twisted pair: copper wires twisted into pairs. • Coaxial cable: consist of copper or aluminum wire surrounded by an insulating layer. • ITU-T G.hn: uses existing home wiring to create high speed LAN. BACK

  6. Essential hardware for a computer to be connected toLAN • Hub/Switch- interconnected multiple devices to LAN. • Router- distribute shared internet access from WAN to LAN. • NIC (Network Interface Card) • Cabling BACK

  7. LAN topologies LAN topologies is the layout pattern of interconnections of the numerous fundamentals of a computer network. BACK

  8. 3 Structures of Topologies • Bus Topology: use a common backbone to connect all devices. • Ring Topology: has two neighbors for communication purposes. • Star Topology: a central connection point named a “hub node” that may be network hub, switch or router. BACK
