Is this an error, or a normal acceptable event?
3) Ethernet has a theoretical efficiency of ~38%. What is the practical limit to how fast a 100 Mb ethernet can send data?
5) Suppose a packet is sent on an ethernet. There are no collisions. Is the packet received by the receiver?
7) Give one advantage of Token Ring over ethernet, and one disadvantage
8-9) Normally, an ethernet card will wait a random amount of time
after a collision before it begins to retransmit. Suppose I modify
my card so this it retransmits immediatly after a collision. What
will I, the user, notice?
Suppose everyone in my department does the same thing. What will
we notice?
10) Will an ethernet receiver ever receive a packet other than
the one transmitted. In other words, can corrupted data ever be received?
Explain.
11) Suppose two cards with the same MAC address were placed
on different ethernets. What would happen?
12) My ethernet serves two departments, each with it's own server.
It's Tuesday, March 13th. Buffy the Vampire Slayer is on. Half
the computers are Macs, the other half PC. Each department has 1/2
the Macs and 1/2 the PCs. I notice that my ethernet is very slow
to send data. Further, there are LOTS of collisions. Most of
the data sent are image files (we're a graphics workshop). Green
iMacs are 10% faster than blue iMacs. What can I do to
speed my network? Feel free to draw a picture, if that helps (or
don't if it does not).
13) Suppose I ethernet keep as it is, except that I double
the maximum cable length. What else must I change (if anything)?
14) (Yes/No) Does ethernet use frequency division multiplexing?
15) Suppose I have a very lightly loaded network. My one
goal is to minimize the average latency of small messages. Which
is the best type of
network. Why?
17) Where is the Boy Wonder?
