A switch is just a another n/w device which has its own
Advantages and Disadvantages as compared to a
HUB/Router/Bridge etc ... I hope it doesnt have any
disadvantages as such unless and until compared to other
n/w devices[Note : This is just my opinion,please add
details if you have some]

Advantages :
1) Reduces the number of Broadcast domains
2) Supports VLAN's which can help in Logical segmentation
of ports[physical ports].Splitting up the broadcast domain.
3) Intellegent device[compared to Hub's] which can make use
of CAM table for Port to MAC mapping
4) Compared to Bridges ,Switches are more H/w oriented
therefore operations are less CPU intense[Basic operations]
.
5) The cost to number of ports ratio is best .. ie For a
cheaper cost you get switches with more number of ports
available than Routers.

Disadvantages :

1) Not as good as a router in limiting Broadcasts
2) Communication b/w VLAN's need interVLAN routing [Router]
,but these days there are a number of Multilayer switches
available in the market.
3) Handling Multicast packets needs quite a bit of
configuration & proper designing.
4) At times swtiches when in Promiscuos mode is a opening
for Security attacks [Spoofing ip address or capturing
Ethernet Frames using ethereal]

I would definitely arguee with the interviewer that
switches are designed for what they are & there is
disadvatage as such unless it is compared to other layer
devices.At Layer 2 it does what other devices of layer 2
cant do & it was initally meant to work at Layer 2,even
though it works at multiple layers these days.

Reposting it as the Poster name got changed to Guest
probably due to auto logout ..
Also the last few lines had some typo.. corrected them
here.There should be some way to edit the posting in this
site.At least my own posting should be made available for
editing :(

Hi,
The main advantage of Switch is to reduce connectivity
problem .A switch can contain a minimum of 24 ports and
maximum of 48 ports.A Switch is device fo port
configuration Maximum port is speed is 100MBPS and with the
help of switch one can reduce port speed to 10MBPS to
reduce Internet Speed.

Hi,
The Advantages and DisAdvantages of Switch are as follows:
1)A switch has minimum 24 port when compared to Hub
(Advantage)
2)A switch is a device where in a Console port is availabe
to configure particular port(Advantage)
3)A Switch is a device where the required Bandwidth
provided ISP is equally shared among all ports.(Advantage)
4)A switch cannot communicate between different Networks.
(DisAdvantage).

It's so simple....
Advantage:
It send data to the correct destination in the form of frame so it reduce traffic.
It works on Data Link Layer of OSI model.
It's good for small Network.
Disadvantage:
It's costlier than HUB.
If any error occur than very difficult to find.
