The aim here is to learn about a widely used technology in Local Area Networks. To answer these questions, start by reading the Wikipedia entry for Ethernet, then follow links in the article and read wider where necessary. Remember, it's 2 marks per subquestion, so short answers are expected.

Collisions and Connectivity:

a) On ethernet that used a shared coaxial cable to connect several computers, what media access control method was used to resolve collisions?

b) What is the key difference between the way that a hub works, and the way that a switch works?

c) Why is full duplex mode better than half duplex mode?

d) If two devices with different speed and duplex modes are connected, and only one is capable of auto-negotiation, what happens?

Ethernet Frames:

e) How large in bytes is the preamble?

f) What is the purpose of the preamble?

g) How many bytes are used for error checking?

h) What type of error checking is used?

i) What's the minimum frame size in bytes according to the IEEE 802.3 standard?

j) Suppose that a frame smaller than that size is caused by collision. What happens to it?

Just need the answer for i & j, thank you
