Transmission Control Protocol and Internet Protocol TCP/IP
Internet Protocol is actually a communication Protocol coming off from TCP/IP communication suites for computer networking. The TCP Transmission Control Protocol and Internet Protocol enable computers to communicate with each other when computers are connected together.
When computers connected either locally, at home, or at a single location office, these computers are networked as Local Area Network (LAN). Further expansion of these connected computers to other locations can be generated either directly by simple DialUp with a modem via Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Dedicated Lease Line (T1…), or indirectly through the Internet. Thus, these computers are interconnected to become one big network or commonly known as Wide Area Network (WAN).
Initially, the TCP/IP was designed for data communication to the computer networks. All data are encapsulated and compressed before they are transmitted as packets across the networks. When the packets arrive at the receiving end, the packets will be decompressed and reverse back to its data form. Thus, sometimes, it will be referred to as Data Switched Network.
