Networking Switches: Networking Switches A switch is a more sophisticated device than a bridge. Ethernet switches are popular connectivity solutions because they improve network speed, bandwidth, and performance. They also operate at much higher speeds than bridges and can support new functionality, such as virtual LANs. LAN2LAN Switch Wireless technologies: Wireless technologies The two most common wireless technologies used for networking are RF (radio frequency) and IR (infra Red) Three of the most common wireless standards are 802.11a, 802.11b and 802.11 g Wireless RouterNICs Network Interface Cards: NICs Network Interface Cards NICS are layer two devices because each NIC Card carries a unique code called a MAC Address. NICs Control Host or client access to the Networking media A NIC is called a network adapter Fig. 1. Ethernet card. From top to bottom: RJ-45, AUI, and BNC connectors Routers: Routers For long distance communication, WANs use serial transmission If the connection is made directly to a internet service provider, (ISP) the router will be a data terminal equipment (DTE) and use a DTE serial cable However, there are occasions where the local router is required to provide the clocking rate and therefore will use a data communications equipment (DCE) cable. Remember How They Connect: Remember How They Connect A switch to a hub A Cisco router to a switch A Cisco router to a host A host to the console port of a Cisco router A PC to a hub A bridge to a switch A PC to a PC A host to a hub A PC to the AUI of a Cisco router You do not have the permission to view this presentation.
