1

Any computing device connected to a network

Host

2

Your computer

Local Host

3

Not your computer

Remote Host

4

A remote computer that stores the files that make up a Web site. Used server programs to store and share data

Web Server

5

Two popular Web server programs

Apache HTTP Server and Microsoft Internet Information Services (IIS)

6

Computer that has enabled a printer-sharing program built into Windows so that other computers on the network can use the printer

Print Server

7

A networked host that enables you to access a bunch of files and folders

File Server

8

The networked host you use to access email messages

Mail Server

9

Expansion card or motherboard interface that enables a PC to connect to a network via a network cable. A wireless one enables connection via radio waves rather than a physical cable

Network Interface Controllers (NICs)

10

Unique 48-bit address assigned to each network card. IEEE assigns blocks of possible addresses to various NIC manufacturers to help ensure that the address is always unique. The Data Link Layer of the OSI model uses these to locate machines

Media Access Control (MAC) address

11

Name coined by Xerox for the first standard of network cabling and protocols that define everything necessary to get data from one computer to another. Since its inception, it has gone through hundreds of improvements and even forms the basis of wireless networking signals

Ethernet

12

Improvement in Ethernet in areas such as speed, signaling, and cabling

Ethernet Flavors

13

Ethernet cabling system designed to run at 10 Mbps on twisted pair cabling

10BaseT

14

Ethernet cabling system designed to run at 100 Mbps on twisted pair cabling. Also called Fast Ethernet

100BaseT

15

Ethernet cabling system designed to run at 1000 Mbps on twisted pair cabling. Also called Gigabit Ethernet

1000BaseT

16

A hybrid network topology where the computers all connect to a central bus - a switch - and have a layout resembling a star

Star Bus Topology

17

Device that filters and forwards traffic based on some criteria. A bridge and router are both examples of them. “Smart” repeater, they memorize the MAC addresses of all the connected devices and only send out repeated signals to the correct host

Network Switch

18

Electronic device that sits at the center of a star bus topology network, providing a common point for the connection of network devices. “Stupid” repeater, anything sent in one port automatically went out to all the other connected ports

Hub

19

The capacity of a network to transmit a given amount of data during a given period

Bandwidth

20

The connection between a computer and a switch. Most cable types, limited to 100 meters or less

Segment

21

The specified cabling for 10/100/1000BaseT and is the predominant cabling system used today. Consists of AWG-22-26 gauge wire twisted together into color-coded pairs. Each wire is individually insulated and encased as a group in a common jacket

Unshielded Twisted Pair (UTP) cabling

22

Standard telephone line

Cat1

23

Designed for 10-Mbps networks; a variant that used all four pairs of wires and supports 100-Mbps

Cat3

24

Designed for 100-Mbps networks

Cat5

25

Enhanced to handle 1000-Mbps networks

Cat5e

26

Supports 1000-Mbps networks at 100-meter segments; 10-Gbps networks up to 55-meters

Cat6

27

Supports 10-Gbps networks at 100-meter segments

Cat6a

28

Supports 10-Gbps networks at 100-meter segments; shielding for individual pairs reduces crosstalk and noise problems. Not an ANSI/TIA standard

Cat7

29

Consists of twisted pairs of wires surround by shielding to protect them from EMI (electromagnetic interference). Tends to be used in places with excessive electronic noise like a shop floor area with lots of lights, electric motors, or other machinery that cause problems for other cables

Shielded Twisted Pair (STP) cabling

30

Connects your telephone to the telephone jack in the wall. Supports up to 2 pairs of wires, though most phone lines use only one pair. Other pair is used to support a second phone line. Primarily used for telephone-based Internet connections

Registered Jack (RJ)-11
