Explain the advantage and disadvantage of Ethernet?

Answer 1

An ethernet connection is known as 'wired' and is quicker and more secure than wifi. A disadvantage is that the ethernet cable connecting the computer and router needs to be in place at all times.

Answer 2

advantages of vlan:

1>broadcast control:

normal function of n/w.

if we segment a larger lan to smaller vlans we can reduce broadcast traffic as each broadcast will be sent on to the relevant vlan.

2>SECURITY

provides enhanced n/w security.

n/w administrators have control over each port and user.

n/w administrator controls each port &whatever resources it is allowed to use.

3>COST:

segmenting a larger vlan to smaller vlans is cheaper than creating a routed n/w with routers because normally routers are costlier than switches

4>PHYSICAL LAYER TRANSPARENCY:

vlans are transparent on the physical topology & medium over which the n/w is connected.

DISADVATGES:

1>NEEDS A ROUTER.
