Dial-up Internet access is a type of Internet connectivity that operates through a standard telephone line. By running the telephone line to a modem device in the personal computer, and configuring the computer to dial a specific phone number, the computer is granted Internet access. This is offered through a number of Internet service providers (ISPs). Most ISPs lease a set of telephone numbers, sometimes local, sometimes national, that dial into network pipelines that feed into the Internet. Subscribers to the ISP normally pay a monthly or yearly fee. For this fee, the subscriber can access the Internet any time of the day or night to cruise the World Wide Web, send and receive email, participate in IRC chat rooms and USENET newsgroups.
Dial-up connections to the Internet require no infrastructure other than the telephone network. Where telephone access is widely available, dial-up remains useful to travelers. Dial-up is often the only choice available for rural or remote areas, where broadband installations are not prevalent due to low population density, and high infrastructure cost. Dial-up access may also be an alternative for users on limited budgets, as it is offered free by some ISPs, though broadband is increasingly available at lower prices in many countries due to market competition.
Dial-up requires time to establish a telephone connection (up to several seconds, depending on the location) and perform handshaking for protocol synchronization before data transfers can take place. In locales with telephone connection charges, each connection incurs an incremental cost. If calls are time-metered, the duration of the connection incurs costs. Dial-up access is a transient connection, because either the user, ISP or phone company terminates the connection. Internet service providers will often set a limit on connection durations to allow sharing of resources, and will disconnect the user—requiring reconnection and the costs and delays associated with it. Technically-inclined users often find a way to disable the auto-disconnect program such that they can remain connected for days.
People find the dialup internet accessible for them because it is the least expensive than the latest and fastest internet connection, the DSL and the hand carry broadband in which you need to top up. It is a piece of USB used as a modem to connect through the computer, right there and then, you can access internet. Though dialup is affordable for most of the users of internet but it is not worth your pesos. It is the slowest type in internet access. Due to the limited bandwidth the ability of the modem to send and receive data, the dial-up service can take up to five minutes to download even just one megabyte of data. Caching frequently visited pages, and other software tricks and tweaks can speed up the experience of dial-up access in some cases. However, if your main purpose online is multimedia-centric, such as searching music, movies, and researching, dial-up service may be so slow as to be unsatisfactory.
