14
Q

A method of accessing a network in which the different nodes on the network segment compete to see which node can send out its packet first. (Or, in other words, a contest between nodes to see which one can access the network first. I wonder if there’s a ribbon. I have no clue what the hell this means, so maybe I’ll read this section of the book)

16
Q

A process that allows either the header or the entire data packet to be encoded using a predetermined algorithm in such a way that if an eavesdropper on the network can intercept the data as it’s transmitted, he still can’t understand it without knowing how to decode it.

A

Encryption

17
Q

One of the oldest and the most widely used LAN technologies in use today that defines numerous wiring and frame header standards.

A

Ethernet

18
Q

A revision of Ethernet_802.3 in which an identifier number is included to enable the frame header to work with the Data Link layer of the OSI Model. (WTF)

A

Ethernet_802.2

19
Q

A version of Ethernet, developed by Novell, that doesn’t include a Layer 2 Data Link identifier. As a result, it can work only with Novell’s IPX packets. See Novell Ethernet. (WTF)

A

Ethernet_802 .3

20
Q

A method of combining the bandwidth from two or more Ethernet links, to push data through a connection at a higher rate.

A

Ethernet Bonding

21
Q

The most widely used Ethernet frame type that can be used directly by the Internet Protocol (IP).

A

Ethernet DIX/Ethernet II

22
Q

revision of the Ethernet_802.2 Logical Link Control standard that allows a larger number of protocols to run on the network.

A

Ethernet SNAP (Subnetwork Access Protocol)

23
Q

A data transmission speed of billions of bits per second.

A

Gigabits Per Second (gbps)

24
Q

A type of wireless network that uses a wireless access point (WAP) to control access and is often connected to a larger wired network.

A

Infrastructure Wireless Network

25
Q

A data transmission speed of thousands of bits per second.

A

Kilobits Per Second (kbps)

26
Q

A bonding method in which multiple network cables and ports are used to increase link speed.

A

Link Aggregation

27
Q

A technology in which only a pre-programmed MAC address is allowed access to a specific wireless access point (WAP).

A

MAC Address Filtering

28
Q

A data transmission speed of millions of bits per second.

A

Megabits Per Second (mbps)

29
Q

A form of bonding which makes it possible to bind two or more ports together on certain switches to allow for fault tolerance or greater throughput between switches or between a switch and a router. Also known as port bonding. (WHAT?!)

A

Multilink Trunking (MLT)

30
Q

A bonding technique that provides network redundancy.

A

Network Fault Tolerance (NFT)

31
Q

Another name for the Ethernet_802.3 frame type, which can run only with Novell’s IPX packets. (WTF is a Novell Packet)

A

Novell Ethernet

32
Q

A form of bonding which makes it possible to bind two or more ports together on certain switches to allow for fault tolerance or greater throughput between switches or between a switch and a router. Also known as Multilink Trunking (MLT). (WTF)

A

Port Bonding

33
Q

A bonding technology that protects data stored at the file system level by providing redundancy across network nodes much like RAID does across hard disk.

A

Redundant Array of Independent Nodes (RAIN)

34
Q

The network name for a particular wireless access point (WAP).

A

Service Set Identifier (SSID)

35
