The document discusses the history and definition of the Internet. It began in the 1960s as ARPANET, a network created by the Advanced Research Projects Agency (ARPA) to link computers. The Internet uses TCP/IP protocols to break data into packets that are transmitted over networks and reassembled at their destination. It functions as a global system connecting various private, public, academic, business, and government networks around the world. The document also lists some advantages like sharing information, communication, education, and entertainment. However, disadvantages include viruses, security issues, potential for immorality, accuracy concerns, time wasted, and language barriers.

It is a combination between hardware and software.It is a global system of interconnected computer networks: private, public, academic, business and government networks.It is a global data communication system: the inter – linked hypertext documents of the World Wide Web (WWW): websites, blogs, wikis (wikipedia, webpages) and the infrastructure to support electronic mail.DEFINITION

TCP/IP (Transmission Control Protocol/Internet Protocol) *Describe data electronicallyTCP/IP creates a packet-switched network. *Minimize the chance of loosing dataSTEPS: TCPBreak down the pieces of data into packets.The packet is wrapped.The IP protocol determines how data is sent and received.Router: receives and passes the packets.TCP identifies and verifies each packet.Back to their original form.HOW DOES IT WORK?
