Website

                  A website is a collection of web pages which are interlinked to each other. A website may contains
                  thousands of web pages.
                  Web Portal

                  A website that is specifically designed to provide a single point of access for information is

                  called web portal. Web portals are also known simply as portals. The major difference between
                  a website and a web portal is that a portal works as a gateway to WWW and provides several
                  services. On the other hand, a website may provides only some limited services.
                  Hypertext

                  The text that has a special feature of connecting one web page to another is called a hypertext.
                  Link

                  A link can be defined as a web address that is used to make connectivity between web pages.
                  Hyperlink

                  A hyperlink is simply a part of the Web page that is linked to a URL. A hyperlink can appear
                  as text, an image, or a navigational tool such as a button or an arrow. When you click on a
                  hyperlink, you will jump to the URL specified by the hyperlink. Hyperlinked text usually looks

                  different from normal text in a Web page. It is often underlined, but can be formatted in a
                  number of ways.
                  Bandwidth

                  The capability of a transmission medium to transmit the maximum amount of data from one
                  computer to another over a computer network in a given amount of time is called bandwidth.
                  A bandwidth is generally in bits per second (bps) or Bytes per second (Bps), Kilobytes per second

                  (Kbps) and Megabytes per second (Mbps). There can be various types of bandwidths which are
                  network bandwidth, data bandwidth, or digital bandwidth.

                      DEVICES REQUIRED FOR A NETWORK

                  There are various types of devices such as Network Interface Card (NIC), Hub, Switch, Router,
                  Modem and Network Cable. Let us discuss about these in detail.
                  Network Interface Card (NIC)

                  It is an expansion card  which  provides  the  network  access to  a  computer.
                  It allows the computer to connect to a network through a wired or wireless

                  medium.
                                                                                                             NIC
                                              Hub or Switch

                                              It is hardware device that has various boxes to which the computers,
                                              printers  and other  networking  devices are  connected.  The  main
                                              function of a hub is to direct information around the network and
                        Hub or Switch
                                              facilitate communication between all the connected devices.
