Document Summary
Network basics: when a cable is said to be able to transmit x mbps this is known as the bandwidth of the cable. 8 bits = 1 byte: mega = million, when wanting to connect multiple computers there are three devices that can help accomplish this task: Repeater a device used to boost signal, if your cable needs to run longer than the max distance (100m usually: amplifier repeater: simply boosts the entire signal they receive, including any noise. Signal repeater: regenerates the signal and doesn"t broadcast the noise. The switch basically an intelligent hub, when the switch receives a packet, it will only send the packet to the computer it is meant to go: the switch can read the data transmission section of the packet. The router if you want to connect two or more networks, you would use a router.
