A component in Windows 95 (and Windows 98) that enables you to connect your computer to a network via a modem. If your computer is not connected to a LAN and you want to connect to the Internet, you need to configure Dial-Up Networking (DUN) to dial a Point of Presence (POP) and log into your Internet Service Provider (ISP). Your ISP will need to provide certain information, such as the gateway address and your computer's IP address. You access DUN through the My Computer icon. You can configure a different profile (called a connectoid) for each different online service you use. Once configured, you can copy a connectoid shortcut to your desktop so that all you need to do to make a connection is double-click the connectoid icon.

Dial-up access is a form of Internet access through which the client uses a modem connected to a computer and a telephone line to dial into an Internet service provider’s (ISP) node to establish a modem-to-modem link, which is then routed to the Internet.
Most ISPs provide dial-up connections supporting PPP because it is a fast and efficient protocol for using TCP/IP over serial lines. PPP is designed for two-way networking; TCP/IP provides the transport protocol for data.
PPP (Point to Point Protocol) uses several components on your system. The first is a daemon called pppd, which controls the use of PPP. The second is a driver called the high-level data link control (HDLC), which controls the flow of information between two machines. A third component of PPP is a routine called chat that dials the other end of the connection for you when you want it to.
Configuring a Dial-Up Connection in Ubuntu
Ubuntu includes some useful utilities to get your dial-up connection up and running.Here is the following ways you can connect to your dialup connection
1)Using your networking option in Ubuntu
2)using gnome-ppp
3)using kppp (For Kubuntu)
4)using wvdialconf & wvdial
5)using pppconfig & pon/poff
first thing you need to make sure your modem drivers are installed or not.If you want more details about modem drivers in ubuntu and installation check here
