Presentation transcript:

Hardware & Software Needed For LAN and WAN Network Interface Card – connects the device to the network and allows communication between the computer Wireless Access Point (WAP) – connected to the network by a cable and positioned so that it can send and receive the wireless signal Modem – converts digital to analogue signals and back again Router – sends info between networks using the topology by selecting the best path. Translates information between networks. Can connect a LAN to a WAN Hub – joins lots of computers to the network via a single link. Signals received on any port are transmitted to all other ports. Switch – receives data, examines it and then sends it to the appropriate port.

Hardware & Software cont. Gateway – connects and passes packets between two network segments that use different communication protocols Bridge – connects and passs packets between two network segments that use the same communication protocols Repeater – Used to strengthen a signal as I is passed along a network cable. Over a distance, a signal would degrade Server – controls aspects of the computer Eg printer server internet server
