Electronics device for data communication





  • What is a bridge?

An electronic device that connects two LAN’s together so that they can share resources.

  • What is a repeater?

An electronic device that connects the segments of a network eg LAN so as to boost the transmitted packets at every segment.

  • Define router

An electronic device that connects devices with different network protocols and translates between network architectures

  • State the function of bridge

  1. It is used to connect two LAN’s
  2. List any two functions which a bridge cannot perform
  3. Traffic management function
  4. Determining most efficient path

  • What is hub?

Central locations in networks that bring media segments together

  • State important types of hubs

  1. Intelligent hub
  2. Active hub
  3. Passive hub



  • Mention the function of hub

  1. Extend the length of network
  2. Provides multiple interfaces
  3. Provides centralized management services

  • What is the main function of gateway?

  1. connects networks that use different protocols
  2. A gateway operates at which layer?
  3. Layer 3- Network layer

  • What are the factors a gateway handles?

  1. Data format
  2. Data rate
  3. Data size

  • What is meant by active hub?

A central connecting device in a network that regenerates signals on the output side to keep the signal strong.

  • How does a router differ from a bridge?

A router is an electronic device that routs/connects independent LAN’s or WAN’s to create an internetwork whereas a repeater is an electronic device that connects the segments of a network eg LAN so as to boost the transmitted packets at every segment.
