VoIP is a time sensitive technology

VoIP is a time sensitive technology. Calls must be set up and authenticated, and voice packets must arrive at their destination without interruption and on time. This requires a near continuous network stream, uninterrupted by less sensitive data transmissions.... READ...

Prior to switches

Prior to switches, Hubs were the standard for connecting devices on a local area network (LAN). The problem with hubs was that everything that went through them had to share the bandwidth of the link, bandwidth was wasted because all traffic was sent... READ...

Other important advantages to switches include the "plug and play" element

Other important advantages to switches include the "plug and play" element. Switches can determine ethernet addresses in use on each segment and create a table as signal packets are passed through the switch. Furthermore, they are versatile enough to... READ...

Routers work in a manner similar to switches and bridges

Routers work in a manner similar to switches and bridges in that they filter out network traffic. Rather than doing so by packet addresses they filter by specific protocol. Routers were born out of the necessity for dividing networks logically instead... READ...
