Network categories: Networks are categorized based on geographic span: local area networks,wide area networks,and metropolitan area networks.Network providers: At the top of the hierarchy are national service providers (NSPs),private companies that own and maintain the worldwide backbone that supports the Internet.Regional service providers (RSPs)offer Internet service by connecting to NSPs,but they also can connect directly to each other.Another level down are the Internet service providers (ISPs); recall from Chapter 3 that an ISP provides access to the Internet for a monthly fee.A modem is a device that enables a computer to transmit and receive data.Broadband is a high-speed Internet connection that is always connected.Digital subscriber line (DSL)allows high-speed digital data transmission over standard telephone lines.Internet cable connections provide Internet access using a cable television company's infrastructure and a special cable modem.A T1 line is a type of data connection able to transmit a digital signal at 1.544 Mpbs.Network protocols: A protocol is a standard that specifies the format of data as well as the rules to be followed during transmission.Network access technologies use a standard Internet protocol called transmission control protocol/Internet protocol (TCP/IP); it provides the technical foundation for the public Internet as well as for large numbers of private networks.Network convergence: Network convergence is the efficient coexistence of telephone,video,and data communication within a single network,offering convenience and flexibility not possible with separate infrastructures.Voice over IP (VoIP)uses IP technology to transmit telephone calls.Internet protocol TV (IPTV)distributes digital video content using IP across the Internet and private IP networks.
