Internet Overview - ubalt.edu

Internet Overview Fall 2007 What is the Internet? A network of networks, bringing together people, information, hardware and software around the World. You can connect to the Internet: dialing out to an Internet Service Provider (ISP) using SLIP (Serial Line Internet Protocol) or PPP (Point to Point Protocol). directly through Cable Modem, DSL (Digital Subscriber Line), dedicated ISP connection, using TCP/IP (Transmission Control

Protocol/ Internet Protocol). dialing out to a computer connected to the Internet using a common communications package and using Internet packages in the remote computer. How does it work? Through a Domain System Structure for example an Internet address (URL) like home.ubalt.edu tell us that this address: (a) belongs to the .edu -- education -- domain, (b) is part of a network called ubalt (of course the name of the UB network), and (c) that the machine

(computer) name is home. there are many different (top) domains like gov, mil, com, net, etc, with new ones being added presently. each computer is assigned an IP number, like 198.202.0.35 -- the home.ubalt.edu IP number. a computer with a Fully Qualified Domain Name (FQDN) has a fixed IP number and name registered in the Internet. What can you do in the Internet?
