What else can I help you with?
What is the definition of internal component of system unit?
It is defined the component which is control the system. It consists of router, bridge, switch, hub, repeater. All the components are acted at the same time.
Discuss allthe network devices used indifferent layer oftheosi model?
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
Which device is used to communicate between broadcast domains?
A router. The key word is create. you can not create a domain using a switch, repeater, or hub.
Which device extends a collision domain?
Bridge, Switches, Router.
What does multicasting have to do with hubs?
Multicasting can be done on a hub but a hub does not need it always. Configuring a router or switch to use multicasting requires that the router or switch be IGMP capable.
Can an active Hub can act as a Repeater?
An active hub can act as a repeater hub. It may also work as an Ethernet hub, network hub, and a multiport repeater.
Is a router a hub or a switch?
More like an antennae.
What are the disadvantages of a router?
a) Router is more expensive than Hub, Bridge & Switch. b) Router only work with routable protocol. c) Routing updates consume bandwidth. d) Increase latency due to greater degree of packet filtering.
Is switch network device?
Yes, switch as well as hub and router are network devices.
What is a device on a network called?

A computer on a network is called a networking computer. http://en.wikipedia.org/wiki/Computer_networking_device
An integrated router can perform the action of which other 2 devices?
switch and hub
Why do routers forward packets slow?
Granted a router is a slower device than a hub, repeater, or switch or bridge. This is because it must look at the entire frame and decode the layer 3 information to decide whether or not to forward/route a packet to another network. The decision on routing takes time as well, because the router must consult its routing tables to determine the best route. This makes the router device a slower device than devices operating at a lower OSI layer level.
