Internet service can be provided through telephone lines .Internet connection speed can generally be divided into two categories: dialup and broadband
Characteristics of the Internet:
The characteristics of the Internet that affect its usefulness in service can be divided broadly into Information and Connectivity. “The advantages arise from the Internet’s enormous capacity to link participants with information and with each other.
