                        NEED FOR COMPUTER NETWORK


                 Computers and other devices connected on a network help in:
                    Resource Sharing: It helps the users to share files and hardware devices such as printers, scanners,
                   etc.
                    Communication: It helps us to communicate with others through e-mail, video conference, instant

                   messaging, etc.

                        ADVANTAGES OF COMPUTER NETWORK


                 The advantages of computer network are:
                   The information can be easily shared with others.

                   It reduces the cost of hardware.
                   Store information in one centralised location.

                    Reliability implies backing up of information. If a system crashes, then the information is accessible
                   on another workstation for future use.
                   Reduction in installation cost.
                   User authentication process to secure the data.

                    People will have access to all the information they need to get and share through e-mail and instant
                   messaging which saves time and money in passing information.

                        COMPONENTS OF A NETWORK


                 There are mainly five components of a network which are as follows:

                   Sender: A sender is a computer that wants to send information to other computer connected to the
                   network.

                   Receiver: A receiver is a computer which is expecting the data from another computer on the network.
