 Need calrification
i have a couple of qs and was hoping to get the truth.
1.Your network is congested what works best for this solution?
A router
B switch
C hub
i would think a router is the best solution because congested networks have tons of broadcasts and routers do not forward broadcasts.
or is congestion due to lots of collisons?
if then the switch would be best.
2.you have an ip address 172.67.45.128/30
what does the ....> /30 mean subnets?
hosts?
3. ping resides on which layer? i was thinking network, since icmp,arp and those reside there also.
4. i know that a router will not flood broadcasts.
but does a bridge flood multicasts?
thank you all

unless you are connecting 2 (or more)networks together you should use a switch... plus routers increase latency with about 15% latency... switches increase latency by about 10%... go with the switch if you staying within the network... make it a cisco or a 3com switch

/30 means the first 30 bits in the subnet mask are ones. When you write down the mask as a 32 bit binary number, it looks like this:
111111111111111111111111111111
00
You now divide this in groups of 8 bites (that would give you four bytes):
11111111.11111111.11111111.11111100
and write the bytes in decimal:
255.255.255.252
You need a bit (no pun intended) of binary math to master this...

Ping as an ICMP message type would be network layer. Ping as in the program you use to check if some remote host is alive would be application layer.

Yes.
