SSC CGL GENERAL INTELLIGENCE: NETWORK TOPOLOGY & NETWORKING DEVICES (LECTURE 2)

NETWORK TOPOLOGY

The geometric arrangement of a computer system. Each computer system in a topology is known as a node.

TYPES OF NETWORK TOPOLOGY

network6

Bus Topology: Single line to which all nodes are connected and the nodes connect only to this bus.
Mesh Topology: At least two nodes with two or more paths between them.
Ring Topology: Every node has exactly two branches connected to it. The ring is broken and cannot work if one of the nodes on the ring fails.
Star Topology: The peripheral nodes are connected to a central node, which rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, including the originating node.
Tree Topology: Nodes’ are arranged as a tree. The function of the central node in this topology may be distributed.

NETWORKING DEVICES

  • Network Interface Card (NIC)– Physical connection between networking cables and computer’s internal bus is provided by NIC Card
    network8
  • Repeater- Electronic device that amplifies the signal it receives. It receives a signal and retransmits it at a higher level or higher power so that the signal can cover longer distances.
    network9
  • Hubs- Forwards the data packets to all of its ports connected to.
  • Bridges– Connects two sub-networks as a part of the same network.
  • Switch– filtering and forwarding of data packets.
  • Router– Connects two sub-networks as a part of the same network
    network10
  • Gateway– Entrance between two network
  • Ethernet– LAN Technology which strikes a good balance between speed & cost.
  • MoDem- Modulates and demodulates the signal between the digital data of a computer and the analog signal of a telephone line.
  • Fibre Distributed Data Interface (FDDI)- Form of network configuration which uses ring topology of multimedia
