Broadband
Internet is a faster way to connect to the Internet. You pay a fixed cost
and you get a whole new world of Internet services at lightning fast speed. The
Internet comes to you throughyour telephone line connection. This connection is
always on, so you can access the web 24 hours per day.
Broadband
connections are nearly 10 times faster than dial-up connections so you don't
wait forever for things to download.
What is ADSL?
Broadband
ADSL enables a broadband "always on" connection to the Internet.
What is SDSL?
Short for
symmetric digital subscriber line, a technology that allows more data to be
sent over existing copper telephone lines (POTS.). SDSL supports data rates up
to 3 Mbps.
SDSL works by sending digital pulses in the high-frequency
area of telephone wires and can not operate simultaneously with voice
connections over the same wires.
SDSL requires a special SDSL modem.
SDSL is called symmetric because it supports the same data rates for upstream
and downstream traffic.
What is A Leased Line
A
permanent telephone connection between two points set up by a
telecommunications common carrier. Typically, leased lines are used by
businesses to connect geographically distant offices. Unlike normal dial-up
connections, a leased line is always active. The fee for the connection is a
fixed monthly rate. The primary factors affecting the monthly fee are distance
between end points and the speed of the circuit. Because the connection doesn't
carry anybody else's communications, the carrier can assure a given level of
quality
Unmetered Dial Up
Account
Unmetered dialup is where an internet dialup user can connect to
the internet using an analogue or ISDN BT line and pay a fixed monthly charge
with no additional call charges. (Subject to our Acceptable Use Policy). You
need one of the following products from BT. Standard analogue PSTN line, ISDN 2
or ISDN 30.
What is a Domain Name
A
name that identifies one or more IP addresses. For example, the domain name
microsoft.com represents about a dozen IP addresses. Domain names are used in
URLs to identify particular Web pages. For example, in the URL
http://www.pcwebopedia.com/index.html, the domain name is
pcwebopedia.com.
Every domain name has a suffix that indicates which top
level domain (TLD) it belongs to. There are only a limited number of such
domains. For example:
- gov - Government agencies
- edu - Educational institutions
- org - Organizations (nonprofit)
- mil - Military
- com - commercial business - commercial
business
- net - Network organizations
- ca - Canada
- th - Thailand
- co.uk - United Kingdom
Because the Internet is based on IP
addresses, not domain names, every Web server requires a Domain Name System
(DNS) server to translate domain names into IP addresses.
