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.

                  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.



                            TYPES OF NETWORKS


                  Networks can be classified based on their size, complexity and the geographical area covered by
                  them. Let us understand these categories in detail.


                  PERSONAL AREA NETWORK (PAN)
                  PAN refers to the privately owned network. PAN is used to
                  establish communication amongst the computers within the

                  range of 20 to 30 feet. This type of network can be wired or
                  wireless.



                                              LOCAL AREA NETWORK (LAN)
                                  Workstation
                                              LAN  is a digital communication system that interconnects a larger
                                      Server
                                              number of computers and other peripheral devices within a radius of
                                              less than 1 km. This type of network is useful when you want to connect
                                              two different departments in a building (e.g. an office, a building or
                                              a factory). The hardware, as well as software resources, are shared

                                              through LANs. Your school lab is an example of LAN.
