This is a lame question?

Question

I have a final test tomorrow for my class in school and the teacher is asking me: What does Ethernet do and how does it work? How would I go about writing what it does? I don't understand, Ethernet is a LAN technology, what does it do? Beats the hell out of me, how does it work? can anyone explain to me without using Wikipedia information?

Thanks

Ok, how does it work? 4 marks for this question, what could I posibly write? I know what Ethernet is, but why would he ask it in such a retarded way....

What does Ethernet do and how does it work?

That's the lame thing I am talking about ^^ The question is STUPID

Answer 1

you should do your own homework or you're gonna end up working at mcdonalds for $0.03 an hour...

@ardra71 - you wouldn't have looked that good from posting my link 4 minutes later lol

Answer 2

Ethernet functions under IEEE 802.3 standards known as CSMA/CD (Carrier Sensing Multiple Access with Collision Detection).
How this works is that each Ethernet interface known otherwise as a NIC (Network Interface Card) has a unique MAC (Media Access Control) Address. When data is sent on the network, it is broadcasted to all hosts and the only host that responds to that request is the one with the matching MAC address. But how does it know where that is? Most of the computers know the IP address, well the ARP ( Address Resolution Protocol) matches known IP addresses to its appropriate MAC address. And the other way around is called RARP (Reverse Address Resolution Protocol). Finally Ethernet can have data collisions because unlike other LAN technologies such as Token Ring, you don't need a special token allowing only one computer at a time to communicate. The work around this is that when a collision occurs, the communicating hosts stop for a random set of time called a back-off request and then restart transmission after that time has expired. I hope this helps and you didn't get too confused

Answer 3

Ethernet is a LAN technology and is used for network communications It works using the Carrier Sense Collision Detection and Carrier Sense Collision Avoidance. The device that wants to transmit data has to make sure there is no other device transmitting. This is done by sending a special signal or "listening". If another device is transmitting then the device has to wait till the line is clear before transmitting. This is what is know as Collision Avoidance. If two devices happen to place frames on the line at the same time the frame is dropped and both have to wait a random period of time before transmitting. This is the basic premise of Ethernet.

Answer 4

If a student was selected to carry messages between the different classrooms, that student would have created a local network.

Ethernet is a local network used in a company or your home to carry information between the different computers you own.

Ethernet is different from the internet because the internet carries messages everywhere in the world. Each ethernet only carries messages in a small local area - hence the term Local Area Network or LAN.

Answer 5

It's a local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. It is one of the most widely implemented LAN standards.

There is more than one type of Ethernet. By 2001 the standard type was "100-BaseT" which can handle up to about 100,000,000 bits-per-second and can be used with almost any kind of computer.

Local network generally offering a throughput of 10 Mbps or 100 Mbps.

A network protocol defining a specific implementation of the Physical and Data Link Layers in the OSI model (IEEE 802.3). Ethernet is a local area network, using a bus topology, that provides reliable high-speed communications (maximum of 10 million bits per second) in a limited geographic area (eg, office complex, university complex).

A common way of networking PCs to create a LAN.
A local area network used to connect computers, printers, workstations, and other devices within the same building. Ethernet operates over twisted wire and coaxial cable.

Answer 6

Earth to Diskeets, your instructor asked you the question so you would do some research today/tonight. Wikipedia is one source; so is www.howthingswork. You can also google for "ethernet", or "how ethernet works". I encourage you to do the best you can at researching this, there's lots of information out there.

Answer 7

Here's a simplistic answer :)

The Ethernet card is a really big modem. Capable of handling the faster speeds of the broadband, as a phone modem can't.

Answer 8

Tell the teacher that the token ring got caught in the ethernet

Answer 9

I could be wrong but isn't Ethernet how you connect to the internet with cable?

I was going to copy & paste the text so I looked super smart, but nah. Just be sure to rephrase and reformat what you find there or it'll look copied.

Gawd...how I wish the WWW was around in the 80's!

i got ethernet baby
