Evolution of dial up connection
The one of the most important feature that people consider while
connection is the speed of internet connection. Today many
types of internet connections are available. Most common type
of internet connection is dial
up connection. Dial up connection has gone through series
of evolutionary steps over last 40 years. This evolution was mainly
possible due to the ever growing demand of faster speed of data
transfer due to the advance of internet.
The first modems could gain a dial up connection speed up to
300 bits per second (bps). They were mainly used by large organizations
in their internal computer networks to connect dumb terminals.
A dumb terminal is simply a keyboard and a screen. A dumb terminal
at a remote site could get connected through dial up connection
to a central computer. This allowed people to process character
data through computer networks.
Most of the people found easy to get along with dial
up connection speed of 300 bps. The reason is that the data
transmitted in that time was merely stream of characters. At the
dial up connection speed of
300 bps, the modems were capable of transmitting 30 characters
per second. This is a lot more characters per second than a person
can type or read.
The scenario changed when personal computers emerged in the late
1970’s. In one of the most popular network at that time,
a Bulletin board network (BBS), a person could set up a computer
with some BBS software and a modem. The other members of the network
would dial in to connect to the bulletin board and share data.
Later on, in the bulletin board systems, it was possible to transfer
more amounts of data then just a stream of character. Then, with
the emergence of GUI (Graphical User Interface), images also started
appearing on the computer screen. Also, the internet started to
gain popularity in early 1980’s. Now, it was possible to
access web sites and transfer large amount of data over the internet.
In this era, the amount of the data transmission dramatically
increased as people started transferring large programs and images
to and from bulletin board systems. Hence, the 300 bps was no
longer sufficient speed transfer data. Hence, the dial up connection
speed went through a series of evolutionary steps in next 20 years.
Today most common dial up connections run with speed up to 56
kbps (kilo bits per second, 1 kbps = 1000 bps).
With the arrival of broadband connection, the usage of dial
up connection has become less frequent. However, due to the
high prices the faster options have not become very popular. Today,
the dial up connection
is the most common and economic option that a home user seeks
to access internet. Today, several, internet service providers
offer dial up connection at reasonably good speed for a home user.
