The Internet: Key Technology Concept

1. Packet Switching

2. TCP/IP Communication Protocol

3. Client/Server Computing

There are three key technology concept of the internet. First is PACKET SWITCHING. A method of slicing digital messages into packets,  sending the packets along different communication  paths as they become available, and then  reassembling the packets once they arrive at their  destination. On packet switching, it must use router which is special purpose computers that  interconnect the computer networks that make up the  Internet and route packets to their ultimate  destination. Second is TCP/IP (Transmission Communication Protocol/Internet Protocol) communication protocol. Protocol is a set of formating, ordering, compressing and error-checking message. TCP establishes the connections among sending  and receiving Web computers, handles the assembly  of packets at the point of transmission, and their  reassembly at the receiving end, and the IP provides the Internet’s addressing scheme.TCP/IP divide into four layer which is network interface layer, internet layer, trasnport layer, and application layer. Third is CLIENT/SERVER Computing wich is a model of computing in which very powerful  personal computers (clients) are connected in  a network with one or more server computers  that perform common functions for the clients,  such as storing files and software applications.
