Dial-up connection
Dial-up
Internet access is a form of Internet access that uses the facilities of the
public switched telephone network (PSTN) to establish a connection to an
Internet service provider (ISP) by dialing a telephone number on a conventional
telephone line. The user's computer or router uses an attached modem to encode
and decode information into and from audio frequency signals, respectively
Dial up
internet service is provided through several ISP. The majority of internet
service providers give you a set of telephone numbers either national or local
that allows you to dial into a network that feeds into the internet. This
allows you to receive and send email, search the World Wide Web, participate in
chat rooms and plenty of other features the web has to offer.
In order to
get a dial up internet service a person must definitely have a computer and
even more important a modem. There are different types of modems, and most of
them are inexpensive to purchase. You can have an internal modem installed in a
free slot of your computer, or you can have an external modem that's hooked up
to the computer through cables. A telephone line is linked to the modem.

Today, with
multimedia and bigger web pages on the Internet most users have an un-enjoyable
time browsing the Internet using a dial-up connection and try to use other
options. Most users who have the available option use some form of broadband
connection, which allows a much faster download and upload.

Full Answer
Dial-up
Internet was used before broadband connections became commonplace in homes.
While it has largely been phased out as broadband has been adopted, it is still
used in some rural areas and other places to which Internet-service providers
feel are too remote and low in population to run broadband cabling.
From the
user's end, the only equipment required is a working telephone jack connected
to the public telephone network and a computer with either an internal or
external modem. An account is also needed with an Internet-service provider.
Users initiate contact with the remote host when logging into their accounts.
The modem uses "handshake" signals to first initialize the
connection, then to make contact with the host and to provide the user's login
credentials. This procedure is accompanied by a unique sequence of electronic
noises that are instantly recognizable to anyone who has ever used a modem to
connect to the Internet. Some Internet-service providers use an intermediate
acceleration server to improve the speed of the handshake connection and also
the delivery of content from the Internet.
