Broadband and Internet 101 |
by:
James Monahan |
Internet is the World Wide Web. Broadband is the medium that
carries it. Internet is the international computer network
linking together thousands of individual networks. Broadband is
the transmitter of these signals.
The most popular features of the Internet include electronic
mail (of course you know e-mail), discussion groups (called
newsgroups or bulletin boards, where users can post messages and
look for responses on a system called Usenet). There is also the
online conversations or chats, adventure and role-playing games
and information retrieval You can also find electronic commerce
(e-commerce) in the Net where you can buy and sell stuff at the
click of a button.
On the other hand, broadband is the high-speed transmission. It
is used to refer to Internet access which uses cable modems or
DSL (Digital Subscriber Line). Broadband DSL connections are
faster compared to dial-up connections.
Dial-up connections utilize phone lines to connect to the
Internet while broadband uses cables.
High-speed transmission is commonly used to refer to Internet
access via cable modems or DSL, which is faster than dial-up.
For years, "broadband" has referred to a higher-speed
connection, but the actual speed threshold has varied.
Along with digital subscriber line technology, cable modems
ushered in the age of broadband Internet access in developed
countries. Before DSL and cable modems, Internet access involved
slow dial-up access over a public switched telephone network.
Users in a neighborhood share the available bandwidth provided
by a single cable line. Therefore, connection speed can vary
depending on how many people are using the service at the same
time.
While T1 (1.5 Mbps) has been widely used as the threshold,
others have used T3 (45 Mbps) for broadband. For example, after
the turn of the century, South Korea leapfrogged the U.S. in
Internet access, offering DSL up to 50 Mbps and calling their
1.5 Mbps service "light."
Mbps is an abbreviation for megabits per second. It is the data
transfer speeds as measured in megabits. This unit is mostly
used in networking technologies such as broadband.
The World Wide Web (WWW) is the greatest force to the
popularization of the Internet. It is a hypertext system (a
computer based retrieval system) which makes browsing the
Internet both fast and intuitive. The information stored in the
computer networks connected to the Internet forms a huge cyber
library. But the enormous quantity of data and information in
these interconnected computers makes it difficult to retrieve
the information.
This is where broadband comes in because with the use of these
cables, the information available in the Internet can be
retrieved really fast and without hassles.
The broadband medium can carry signals from different network
carriers. This is done through fiber-optic cable. Fiber-optic
cable is a thin glass strand designed for transmission. It is
capable of transmitting trillions of bits per second
Broadband technology can support a wide range of frequencies.
Broadband in general refers to data transmission where multiple
pieces of data are sent simultaneously to increase the effective
rate of transmission. In network engineering this term is used
for methods where two or more signals share a medium.
Various forms of DSL service are broadband in the sense that
digital information is sent over one channel and voice over
another channel sharing a single pair of wires.
