Re: Can I use swticher instead of router in this case?

You should upgrade the switcher to a switcher-oony

That is all.

I don't quite understand when I read the following paragrpahy on Microsoft
Training Kit.

-------
Suppose you are designing a campus network with 200 host spead over four
buildings - Voter Hall, Twilight Hall, Monore Hall, and Sunderland Hall.
You
want each of these four buildings to include 50 hosts. If you ISP has
allocated to you the Class C network 208.147.66.0, you can use the
addresses
208.147.66.1-208.147.66.254 for your 200 hosts. However, because these
hosts
are distributed among four physically separate locations, these hosts are
not
all able to communicate with each other by means of local network
broadcast.
By extending the subnet mask and borrowing 2 bits from the host ID portion
of
your address space, you can divide the network into four logical subnets.
You
can then use a router to connect the four physcial networks.
--------

I wonder if I can use a switcher instead of a router to connect other 4
switchers sitting on each building.

Take the above scenario as an example, the subnet mask is /28
(255.255.255.240).

I guess that the adoption of a router may bring the following advantages:
1. support accessibility of varied subnets.
2. reduce network traffic due to the decrease of the number of subnet's
hosts (default is 254, and it is 62 in this case)

I still not very clear "broadcast" in TCP/IP. When a host sends a data
package, if the destined host is in the same subnet as sender host, the
data
package would be broadcasted in the subnet.
Does it imply that the smaller number of hosts in a subnet will bring more
efficiency?

Tell me something if I missed.

Thank you.
