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
- It is used to connect two LAN’s
- List any two functions which a bridge cannot perform
- Traffic management function
- Determining most efficient path
- What is hub?
Central locations in networks that bring media segments together
- State important types of hubs
- Intelligent hub
- Active hub
- Passive hub
- Mention the function of hub
- Extend the length of network
- Provides multiple interfaces
- Provides centralized management services
- What is the main function of gateway?
- connects networks that use different protocols
- A gateway operates at which layer?
- Layer 3- Network layer
- What are the factors a gateway handles?
- Data format
- Data rate
- 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.
