CSMA/CD

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

10GBase-SR

The 10-Gigabit fiber optic standard with the shortest segment length is __.

Long Reach

In the 10-Base-LR standard, the L stands for __.

Depicts a network in broad scope

A physical topology

Type

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

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.

Bus

The most common logical topologies are __ and ring.

Twisted pair

The 10Base-T standard is considered a breakthrough for transmitting 10 Gbps over __ medium.

Reassembles

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

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.

daisy-chain

A __ is a simply linked series of devices.

WAN's

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

10GBase-SR

The 10-Gigabit fiber optic standard with the shortest segment length is __.

Star

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

Shim

Collectively, MPLS labels are sometimes called a __.

Terminators

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

Ethernet II (DIX)

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.

1 Gbps

1000Base-SX has a maximum throughput of __.

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.

switching

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

Repeater

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

10

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

Collision

A __ occurs when two transmissions interfere with each other.

46 to 1500

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

Cabling

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

1000Base-LX

The most common 1-Gigabit Ethernet standard in use today is __.

True

A network's access method is its method of controlling how network nodes access the communications channel.

True

Most Ethernet networks are based on the star topology.

False

The smallest LANs do not have a backbone.

False

The most popular method for connecting nodes on a network is circuit switching.
