There are three main classes of MAC protocols: channel partitioning, random access, and token ring. Use the Internet search to describe briefly (max 5 sentences) each of these MAC protocols.

hi,
I am happy to help you with this question.
Mac is an abbreviation of media access control.
Here we have to see the main 3 protocols.
- Channel partitioning.
- Random access.
- token ring.
So let us first describe Channel partotioning.
Channel Partitioning: It is a time division based channeling access.
In this we access the location on the basis on time and in multiple rounds.
Each station gets divides into length in each round and the used slots are idle.
It can be subdivided into 2 sub categories : frequency based and time based .
example:6 station LAN.
Random access protocol: It works to find the collisions in the transmitting nodes.
It studies how to detect collisions and how to recover from it.
If there are 2 or more transmitting nodes then it may be in a state of collision.
Example: ALOHA ,slotted ALOHA.
It is basically due to no prior coordination between nodes.
Token Ring: this protocol is used to define the order in which stations are send .
The stations are connected with each other by using a technology called rings.
it does the functioning by using a 3 byte frame called tokens.
these tokens are traveled in a ring structure and uses token access mechanism .
It creates a token channel accessing provides a fair chance to all the stations .
Thank you.
I hope i was able to help you with this question .If you have any queries please be comfortable to ask in the comment section i will be happy to help you.
:)

Overview This assignment will give you experience on the use of classes. Understand the Application Every internet user–perhaps better thought of as an Internet connection–has certain data associated with him/her/it. We will oversimplify this by symbolizing such data with only two fields: a name ("Aristotle") and a globally accessible IP address ("139.12.85.191"). We could enhance these by adding other—sometimes optional, sometimes needed—data (such as a MAC address, port, local IP address, gateway, etc), but we keep things simple and use...

The main point of the exercise is to demonstrate your
ability to use various types of nested classes. Of course, sorting
is important as well, but you don’t really need to do much more
than create the class that does the comparison. In general, I like
giving you some latitude in how you design and implement your
projects. However, for this assignment, each piece is very...
