There is a difference between to connect to a network and to communicate over a network. Connecting to a network requires that special hardware be installed in your computer. This hardware is called connection devices. There are two common types of connection devices: 1- Modem – short for modulator / demodulator - which connects computers using a standard telephone line 2- Network interface card (NIC) – which connects computers using a special type of network cabling Note that, NICs are not synonymous with Ethernet cards. An Ethernet card is a particular type of NIC, and is the most popular in personal computers (PCs). Most of the time, these devices are internal hardware, although they are available as an external peripherals. 6 In order to communicate with another computer over a network, you must do two things: 1. Use the set of rules governing communication over the network, called a protocol. Your computer will generally handle this. 2. Know the address of the computer you want to communicate with. There are two types of network addresses: a. Medium access control (MAC) address which is used inside a single network b. Internet protocol (IP) address which is used on the Internet World Wide Web The World Wide Web (web for short or www) is a collection of interlinked multimedia documents that are stored on the Internet and accessed using a common protocol (HTTP). Form this definition we can say that the web is part of the system that is primarily include software components (text files, graphics files, sound files, video files…).
