Without ______, a bus network would suffer from signal bounce.

repeater

In a ring network, each workstation acts as a(n) _____ for the transmission.

hybrid

A complex combination of pure topologies is known as a _____ topology

In packet switching, when packets reach their destination node, the node _____ them based on their control information.

shim

Collectively, MPLS labels are sometimes called a _____.

CSMA/CD

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

collision

_____ 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

1000Base-T is a standard for achieving throughputs _____ times faster than Fast Ethernet over copper cable.

twisted pair

The 10GBase-T standard is considered a breakthrough for transmitting 10 Gbps over _____ medium.

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 the 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 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 to 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.
