CSMA/CD

All Ethernet networks, independent of their speed or frame type, use an access method called ____.

collision

A ____ occurs when two transmissions interfere with each other.

collision domain

On an Ethernet network, a(n) ____ is the portion of a network in which collisions occur if two nodes transmit data at the same time.

10

WANs

Given their long-distance capabilities, 10GBase-ER and 10GBase-EW are best suited for use on ____.

preamble

Within Ethernet frame types, the ____ signals to the receiving node that data is incoming and indicates when the data flow is about to begin.

46 to 1500

The data portion of an Ethernet frame may contain ____ bytes of information.

type

The Ethernet_II frame type contains a 2-byte ____ field which differentiates it from the older Ethernet_802.3 and Ethernet_802.2 frame types.

star

In a(n) ______ topology, every node on the network is connected through a central device, such as a hub, router, or switch.

cabling

A network backbone is the ____________ that connects the hubs, switches, and routers on a network.

switching

____________________ is a component of a network's logical topology that determines how connections are created between nodes.

jamming

As part of CSMA/CD, a process known as ____________________ allows the NIC issue a special 32-bit sequence that indicates to the rest of the network nodes that its previous transmission was faulty and that those data frames are invalid.

Ethernet II

Because of its support for multiple Network layer protocols and because it uses fewer bytes as overhead, ____________________ is the frame type most commonly used on contemporary Ethernet networks.
