Q

Hub

A

Hs a number of different ports, between 4 and 48 ports. Uses a wired interface with RJ45 connectors. Can operate from 10Mb/s up to 100Mb/s. Slows down the entire connection because a lot of collisions can happen. Everything sent to a host can be listed to by all devices connected to the Hub.

A

Used to measure lots of different things. (ex. temperature, proximity)

34
Q

Twisted pair cables

A

The twist is really important, the more twist is has the more protection it has against electromagnetic interference which will make it faster. The higher the category number, the higher the speed

35
Q

A

Operate about the same. Difference is STP has lees electromagnetic interference

38
Q

Connector types for cables

A

RJ45
-Most common. Plastic 8 pin connector. Look like a fatter version of a traditional lan phone line. Used all the time in ethernet based connections. Cat5 cable only uses 4 of the 8 pins.

RJ11

56
Q

Plenum Cable

A

A special coating put on a UTP or STP cable that provides a fire-retardant chemical layer to the outer insulating jacket. They are for ceilings, walls, raised floors, or air ducts. You cannot use non-plenum cables for this!

57
Q

Fiber Optic Cable

A

Uses light from an LED or laser to transmit information through a thing glass fiber. Greater usable range, greater data capacity. Used in a lot of extremely fast networks

58
Q

Drawbacks of fiber

A

-Expensive
-Difficult to work with

59
Q

Single Mode Fiber (SMF)

A

Used for shorter distances and has a larger core size which allows for multiple modes of travel for the light signal. Core size is 50 to 100 microns in diameter. Up to 2 kilometers or less. Les expensive. Aqua blue cable

61
Q

Fiber cable connectors (NEED TO LEARN SHAPES FOR EXAM)

A

-SC (Subscriber Connector) “Stick and Click”
-ST (Straight Tip Connector) “Stick and Twist”
-LC (Lucent Connector) “Love Connector”
-MTRJ (Mechanical transfer registered jack)

62
Q

Coaxial Cable (Coax)

A

One of the oldest categories of copper media that is still used in networking today. They have F-type and BNC connectors

Snip/Cutter

A

Used to cut a piece of cable off a larger spool or run of cable

65
Q

Cable Stripper

A

Used to strip off the end of the cable and prepare it for attachment to a connector

66
Q

Cable Crimper

A

Used to attach the connector to the end of the cable

67
Q

Cable tester

A

Used to verify the continuity of each of the eight individual wires inside of a twisted pair cable

68
Q

Wire Mapping Tool

A

Works like a cable tester, but specifically for twisted pair ethernet cables

69
Q

Cable certifier

A

Used to determine a cable’s category or data throughput

70
Q

Punch-Down Block

A

Terminates the wires and strips off excess insultation and extra wires that are no longer needed

71
Q

Tone Generator/Toner Probe

A

Used to generate a tone on one end of the connection and use the probe to audibly detect the wire connected on the other side

72
Q

Loopback Adapter/Device

A

Facilitates the testing of simple networking issues

73
Q

Tap

A

Connects directly to the cable infrastructure and splits or copies those packets for analysis, security, or general network management
