  NETWORK DEVICES   What does a Network Device mean? Network devices, or networking hardware, are physical devices that are required for communication and interaction between hardware on a computer network.   EXAMPLES OF NETWORK DEVICE ·          Hub ·          Switch ·          Router ·          Bridge ·          Modem ·          Transceivers ·          Firewall HUB A  hub  is a simple device that directs data packets to all devices connected to it. Basically, a hub does nothing except provide a pathway for the electrical signals and regenerate signal before it forwards it to all connected devices. It can be used with both digital and analog data, provided its s...

  Network Topology It is the layout or structure of the network in relation with the flow of data. It is the way in which the elements such as computers, printers, servers, and other computing appliances are arranged in a network. In this instance, you take note not only of the device's location, but also how it is connected to the network, the type of cables in use, and its layout. Types of Network Topologies 1.)    Linear Bus Topology Is a type of network topology in which each devices is connected one after the other in a sequential chain. It uses one long cable, referred as backbone, to which computers and other devices are attached. A terminator is placed at each end of the backbone to keep the signals from bouncing back and being received again by the nodes. In this case, the bus is the network connetion between the devices, and if any link in the network chain is severed, all the network transmission is halted.   Advantages of Linear Bus Topology • Easy ...
