VoIP:
Voice over Internet Protocol (VoIP), is a technology that allows you to make

analog) phone line. Some VoIP services may only allow you to call other people
using the same service, but others may allow you to call anyone who has a
telephone number - including local, long distance, mobile, and international
numbers. Also, while some VoIP services only work over your computer or a
special VoIP phone, other services allow you to use a traditional phone
connected to a VoIP adapter.
Broadband: Broadband Internet service truly is the most used form of
Internet access because of its high access speeds; it is offered in four
different forms, DSL (or Digital Subscriber Line), also fiber-optic, cable, and
satellite. The old dial-up connection is the only non-broadband internet service
available, and even though it is cheaper, most Internet users are moving
towards the faster broadband Internet connection.
