Dialup UK Article - Basic Internet Connection Terminologies
Many people around the world use internet but are not quite
familiar with some of the basic internet connection terminologies.
There are certain terms related to internet connection that
a common internet user need to understand. The most popular
way to connect internet are Dial up connection, Broadband
connection and speed of internet connection. Let us discuss
them…
In simple terms, dial up connection is the system to get
your computer connected to an internet network. Using dialup
connection a computer can be connected to a LAN (Local Area
Network) or WAN (Wide Area Network) of internet using a telephone
line and a modem. You may use a dial up connection through
various types of modems. Dial up connections are usually cheap
reliable and easy to install and use. In fact, with the advance
of the internet technology, the dial up connection is provided
free (without rent) in some countries.
The most important term associated with dial up connection
is a modem. Modem is a contraction of then term "Modulator
Demodulator." By definition, the modem converts analog
form of data used transmitted through telephone lines into
the digital form used on computers and vice versa. These were
the earlier form of modems called analog modems and PC card
modems. These modems were very popular in the early and middle
ages of internet usage. One of the most popular modem was
a Standard 56K modem. However, limitations of the phone line
made the data transfer speed much lower in practice.
Now days, another type of modems have come into picture.
They are also known as digital modems. These modems have been
designed to gain advanced digital support from the ISP. However,
the terminology “digital modem” is misleading
as all modems involve analog data transmission. The advantage
of the digital modems is that they use broadband signaling
techniques to achieve higher network speeds than traditional
analog modems.
The technology that brought revolution the internet connection
usage is the Broadband connection. The broadband connection
is next step in evolution after dial up internet connection.
The broadband connection is a type of data transmission technique
that allows several data channels to be transmitted over a
common physical line. For example, some broadband internet
service combines separate voice and data channels over a single
broadcast line.
For a home internet user the term, "broadband"
usually refers to high-speed Internet access. For residential
connections, a broadband connection is usually provided through
Ethernet line or cable TV line. Now days, broadband internet
through cable lines is common broadband Internet service in
the developed countries.
One of the most important features of the internet access
is the speed of the data transfer. The internet speed is measured
in bits per second or Bytes per second. Below displayed is
the summery of measurement parameters of each unit.
When the measurement is given in bits per second (bps)…
kbps :- one kilobit per second and equals to 1000 bits per
second (bps).
mbps :- one megabit per second and equals 1000 kbps.
gbps :- one gigabits per second and equals 1000 mbps.
When the measurement is given in Bytes per second (Bps)…
Kbps :- one kilobytes per second and equals to 1000 bytes
per second (bps).
Mbps :- one megabytes per second and equals 1000 Kbps.
Gbps :- one gigabytes per second and equals 1000 Mbps.
