Dialup UK Article - Salient Features Of Dialup Internet
For a common home internet user, the most obvious way to
access the Internet from home is to subscribe a dial up connection.
While using a dial up connection, you need to connect to internet
with a modem and a phone line. You will connected through
main computer of your Internet Service Provider (ISP). Users

telephone line. This is quite easy as most homes already have
phone lines installed. A phone line uses an analog signal
to transmit audio information from your home or office to
the local telephone company. A dial up modem modulates a digital
signal from your computer into an analog signal so that it

form. This modulation and demodulation process causes the
screaming noises that the user hear at the beginning of a
dial up Internet connection. This may also prove to be a limitation
as the regular analog modems only use a small portion of the
available bandwidth that could be transmitted over your phone
line. These modems are restricted in terms of speed it could
achieve over a voice telephone network. Typically, the maximum
amount of data that you can receive using an ordinary modem
is lower then the actual capacity of the modem. The highest
speed that you could achieve is 56kbps. However, it is generally
restricted to 42 to 48 kbps.

from your computer to the Internet. They typically also include
such services like e-mail account, personal web page (often
called home page) and access to Internet newsgroups and bulletin
boards. The data in the e-mail account resides on ISP’s
computer. Some dial up accounts may also include specific
features such as a UNIX shell account. This will enable you
to receive e-mail even when your computer is not connected
to the Internet. On other types of accounts, you can download
the e-mails once you connect to the Internet.

performance. The price may very as per the ISP and area. Some
metro cities and areas that are drenched with high densities
of corporate offices may have several ISPs. The prices of

competition. In rural parts, with a few ISPs to choose from,
prices will be higher.
