Ethernet has access any time it is desired to transmit. It listens first to ensure no other nodes are communicating. If clear, they transmit. Yes, collisions are normal - If two nodes collide (transmit at the same time), they both back off, send a jamming signal, wait a "random" amount of time (based on their MAC address), and resend.

What is token based media access?
Token-based media access is a controlled media access method in which computers pass a special sequence of bits between them; only the node holding this token can transmit on the network. After transmitting its data, or if it has no data to transmit, a node passes the token to the next computer on the network. Neeraj
What is one operational characteristic of a shared-media Ethernet network?
1.All frames are transmitted on all Ethernet segments 2. shared medium networks use CSMA/CD to access the medium
What is true regarding media access control?
The question is a little vague, but a media access control (MAC) address is an address assigned to network interface devices such as an Ethernet card or wireless card. The addresses are assigned by the manufacturer and no two cards share the same number; each must be unique.
Dvrs with Ethernet ports?
DVR's that have ethernet ports are capable of connecting to the internet. With DirecTV, it is used for On Demand downloads and it is also used to access media on all of your PC's that are connected to the same network as the DVR unit. With TiVO units, you can actually go to YouTube and play media from that site.
What are the three network media and the signals they transmit?
The three main types of network media are twisted pair cables, coaxial cables, and fiber optic cables. Twisted pair cables, commonly used in Ethernet networks, transmit electrical signals. Coaxial cables also carry electrical signals and are often used in cable television and internet connections. Fiber optic cables transmit data as light signals, allowing for high-speed and long-distance communication.
How long are Ethernet Mac addresses?
Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
Is the network media control the purpose of the Network Access layer?
Yes it is
In a shared media network of any type if you have 200 stations on the network how many may transmit at a time?
One. If it's shared media, then there can only be one transmitter.
What address do manufacturers of network adapters burn into their products in order to uniquely identify them?
A "MAC ADDRESS" (Media Access Control address), or an EHA (Ethernet Hardware Address), also known simply as "hardware address".
Compare and contast controlled media access and contention-based media access control?
Controlled-based media access control is based upon having a system in place for allowing one host to transmit at a time. It is also known as deterministic method since there is a process to determine which host transmits at a certain time. No collisions exist with this type of media access control. An example would be token ring where a token is passed from host to host and when it has the token it can transmit and others do not transmit at that time. Contention-based media access control is known as non-deterministic because hosts can transmit whenever they want. CSMA/CD is an example of this. Collisions do exist.
What is Ethernet Mac?
The Media Access Control (MAC) address is a number that identifies a computer connected to a network. To find the MAC address on an Apple Mac select About This Mac in the Apple menu (top left), then click on More Info and then on Network in the left hand pane. The MAC address will be listed under Ethernet in the lower right hand pane.
What are connectivity devices that enable a workstation server printer or other node to receive and transmit data over the network media?
There are multiple connection options for a Network Printer. 1. The Printer can be attached to a Router and be available to all of the Network's Computers that can access that router. 2. If the printer is attached to Computer "A" (via USB or WiFi) any Computer on the Network that can access Computer "A" can be allowed to access the Printer. Of course Computer "A" MUST be up and running.
