Broadband, also known as 'wideband', is a term used to compare a frequency bandwidth. These broadband frequencies can transmit more data and at a higher speed than narrowband frequencies. Broadband is capable of carrying multiple voice, video or data channels simultaneously. Each "channel" will take up a different frequency or specific time slot on the cable.

What is a Broadband Network?
A broadband network is a network that uses multiple carrier frequencies to transmit multiplexed signals on a single cable. Several networks may coexist on a single cable without interfering with one another.

What is a Broadband Router?
A broadband router allows you to share your connection with and between multiple computers. It uses a technique called NAT (Network Address Translation) to share your IP address assigned by your cable provider with all your computers. Broadband routers also provide features such as firewalls to make your computers secure while on the Internet.
