10. Explain about voice over IP.
VoIP stands for Voice over Internet Protocol. VoIP is a technology that allows telephone
calls to be made over computer networks like the Internet. VoIP converts analog
voice signals into digital data packets and supports real-time, two-way
transmission of conversations using Internet Protocol (IP).
VoIP calls can be made on the Internet using a
VoIP service provider and standard computer audio systems. Alternatively, some
service providers support VoIP through ordinary telephones that use special
adapters to connect to a home computer network. Many VoIP implementations are
based on the H.323 technology standard.
VoIP offers a substantial cost savings over
traditional long distance telephone calls. The main disadvantage of VoIP is a
greater potential for dropped calls and degraded voice quality when the
underlying network links are under heavy load.
