Compare Networking Hardware

Question 1

is the devices that allow computers to connect to a network
over a certain type of network media and that forward data between computers.

Answer 1

Network Hardware

Question 2

physical connection to the cable is made using a transceiver port in and be able to process the electrical or light signals as digital data, the signals must be divided into regular units with a consistent format (ethernet framing)

Answer 2

Network Interface Card (NIC)

Question 3

has a unique hardware/physical address Each frame of Ethernet data identifies the source address and destination in fields header. Ex. 00:60:8c:12:3a:bc or 00608c123abc

Answer 3

media access control (MAC) address

Question 4

is a numbering system often used to represent network addresses of different types

Answer 4

Hexadecimal

Question 5

In most types of office cabling, the computer is connected to a wall port and—via cabling running through the walls—to a. cables running through the walls are terminated to insulation displacement connector (IDC) punchdown blocks at the back of the panel. patch panel port is connected to which wall port.

Answer 5

Patch Panel

Question 6

A legacy device repeats an incoming transmission from a computer attached to one port across all the other ports and has a number of ports—typically between four and 48—and each computer is cabled to one port.

Answer 6

Hub

Question 7

Each computer attached to a hub receives all the traffic sent by other connected devices

Answer 7

collision domain

Question 8

means that the computer can send or receive, but not at
the same time.

Answer 8

Half-duplex

Question 9

provisions one port for each device that needs to connect to the network. When it receives an incoming frame, the switch intelligently forwards it to the port that is a match for
the destination MAC address. Has full duplex

Answer 9

switch

Question 10

connection to the network and can send and receive simultaneously at the full speed supported by the network cabling and NIC.

Answer 10

Full Duplex

Question 11

an administrator can connect to it over a management port, configure security settings, and then choose options for the switch’s more advanced functionality.

Answer 11

managed switches

Question 12

is a means of supplying electrical power from a switch
port over ordinary data cabling to a powered device (PD), such as a voice over IP (VoIP) handset, camera, or wireless access point.

Answer 12

Power Over Ethernet (POE)
