Bandwidth
and broadband are terms that are commonly associated with the internet.
Bandwidth refers to the amount of data that can be carried from one point to
another in a given time period-usually a second, or bps. Broadband is the name
given to any fast, permanent internet connection. It can be delivered by cable,
satellite, mobile, fiber optics and ADSL, which is technology for high- speed
internet access.
When
the internet revolution began, users accessed the net via dial-up and a ‘modem’
–a piece of hardware that converts signals from your computer, so they can
travel down a telephone line, and vice-versa. This could be painfully slow and
it tied up your phone line. A broadband connection makes internet more
enjoyable as it is so much faster. This is because a broadband connection can
download more chunks of data-‘bits’ simultaneously.
If you want to log on to the Internet, you need a computer that has internet software. You will also need a modem. The data is received by a computer on the net, and routed to its destination. Finally, the destination computer receives, and process the data that has been sent.
