Gateway

        It is a device that  oins two networks of different protocols.
        Gateways serve as the entry and exit point of a network; all data that are routed inward or outward from a
        network must first pass through the gateway in order to route it to destination of data.   router can also be
        considered as a gateway, since it interprets data from one network protocol to another. Generally, a router is
        configured to work as a gateway device in computer networks.

        Bandwidth
        Bandwidth refers to the speed of transfer of data over a network. It represents the capacity of a network for
        supporting data transfers. In system, bandwidth is typically expressed in bits per second like 100 Mbps or 100
        Mb/s. In many devices, the capacity of bandwidth is represented in minimum speed and maximum speed of
        data transfer.

            INTERNET CONNECTIVITY OPTIONS

         here are many ways a device can connect to the Internet.  hey all use different hardware and each has a
        range of connection speed. As technology changes, faster Internet connections are needed to handle those
        changes. Internet connections can be categorised into wired and wireless:

                                    Wired                                    Wireless
