Introduction to dial up connection
Internet is the largest network in the world
that has abundance of data and information. There are several
ways to access internet. The most used way is a dial
up connection. Here, we introduce the oldest and the most
used internet access technology...
Dial up connection is a process in which a device is connected
to a network via a modem and a public telephone network. Here,
for most people the device to be connected is their computer.
Dial up connection is more or less like a phone connection. The
main difference is that in a telephone connection, people directly
converse at both ends. In a dial up connection, parties at the
two ends are computer devices rather than people. This makes a
dial up connection a primary mode of access to internet for most
Technically, dial up access
is a form of internet access in which the end user uses a modem
to dial the internet service provider's central computer. It uses
a dialup server type such as the PPP and TCP/IP protocols to establish
a modem to modem link, which is then routed to the internet. Dial
up Internet connections requires an access number provided
by your local ISP that a modem dials in to get on to the network.
The user must submit a username and password to authenticate the
The main advantage of dial up connection
is that it could be connected through telephone lines. As most
people have phone line in their houses or offices, dial up connection
is easy to set up. It has now become legacy technology in the
advent of widely available broadband
Like most of the modern technologies dial up connection has its
limitations. The most visible limitation is that the dial up connection
system uses normal telephone lines. In most of the premises, the
phone lines are not as good as the dial up connection could have
to transmit maximum data. The main reason is that the telephone
lines were installed over many years. They did not specifically
installed for dial up connections. Hence, the quality of the connection
is not always good and data rates are limited.
Though the speed of dial up connection
has increased in last two decades, the maximum data rate with
normal dial up access is limited to 56 Kbps (56,000 bits per second).
Overall, the dial up connection is slower than other non dial
up forms. It is also not dedicated. It means that it is not always
on. You must dial the service provider every time you want to
connect to the Internet.
The new non dials up technologies such as ISDN are providing
faster rates. An alternative way to connect two computers is through
a leased line, which establishes permanent connection between
two devices. Leased lines provide faster throughput and better
quality connections. Their negative point is that they are very
expensive. The dial up connection is still established as the
most popular option to access internet.
