Internet Protocol
The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched internetwork.IP is the primary protocol in the Internet layer of the Internet protocol suite and has the task of delivering datagrams (packets) from the source host to the destination host solely based on its address. For this purpose the Internet Protocol defines addressing methods and structures for datagram encapsulation.IP supports unique addressing for computers on a network. Most networks use the IP version 4 (IPv4) standard that features IP addresses four bytes (32 bits) in length. The newer IP version 6 (IPv6) standard features addresses 16 bytes (128 bits) in length.
Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or 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.
Networking equipment has simultaneously become more powerful, less expensive, and easier to operate, enabling small and medium-sized businesses (SMBs) to compete with larger companies. “SMBs can now say, ‘We have connectivity throughout our organization, and with our suppliers and customers—what can we do with it to improve the business?’” Eldredge says. Businesses are doing much more than just connecting computers.The internet protocol is specifically limited in scope to provide the
functions necessary to deliver a package of bits (an internet datagram) from a source to a destination over an interconnected system of networks. There are no mechanisms to augment end-to-end data reliability, flow control, sequencing, or other services commonly found in host-to-host protocols.
