They both help a network run efficiently by preventing collisions. Ethernet uses Carrier Sense, Multiple Access with Collision Detection (CSMA/CD). Carrier Sense - when a device connected to an Ethernet network wants to send data it first checks to make sure it has a carrier on which to send its data.
Multiple Access - this means that all machines on the network are free to use the network whenever they like as long as no one else is transmitting
Collision Detection - a means of ensuring that when two machines start to transmit data simultaneously, that the resultant corrupted data is discarded, and re-transmissions are generated at differing time intervals. Token Ring never has collisions because the information (packets) only travel in one direction, and all the nodes on the network communicate so that they know when information is being passed on, each node communicates via a token.

What is the most common set of protocols used on a local wired network?
The most popular is the TCP/IP suite of protocols
What are thevarious type of commuincation cables?
Ethernet cables are the most common type of communication cable. Other types of communication cables are telephone and DSL cables.
There are certain protocols for communication between networks?
There are many ways to communicate between networks. The rules for doing so are called protocols, and there are many known protocols. Some are historical in nature (meaning they have been around a long time) and some are newer ones developed in the last few years. Protocols describe how to communicate and when to communicate. They may be specific to a means of communication (i.e. web traffic, email traffic) or they may be more general (TCP/IP - covering many protocols). Deciding on which protocol to communicate with other networks is based on how the networks communicate currently and what kind of traffic will be transferred between the two. A protocol is designed so that there are common rules regarding communication, so certain protocols will be used to be common between networks. TCP/IP is an example of a very common, widely-used communication protocol.
Which characteristic was common to ancient civilizations in Egypt sumer and china?
Written forms of communication
Why are data link protocols required?
Protocols are a commonly agreed-upon set of rules for common communication between devices. At the data link layer they have to agree on the rules of how the frame is constructed, otherwise there would be no correct way to deliver frames to the intended systems.
Why is Ethernet so common?
Ethernet cabling is cheap and fast enough for most purposes.
Which components are part of a windows 7 network connection?
clients services protocols network drivers
Three common protocols to modern computer networks?
The main communication or network protocol is the TCP/IP protocol. (Transmission Control Protocol/Internet Protocol)
Why are there several different data link layer protocols in common use on the internet?
Because the internet is not homogeneous. Some segments of the internet are ethernet, some are SONET, ect. Some datalink layer protocols are more suited for one application than another. What links all these segments is the Network protocol. The network protocol used on the internet is IP.
What is a common characteristic for fascist governments?

Ethernet
What is common to all Ethernet implementations?
Speed
