Answer 10

A method to detect and handle data collisions in wired networks.

Question 11

Hub(in context of 10 BASE-T)

Answer 11

Repeats signals to all connected devices, creating a single, large collision domain.

Question 12

10BASE-T

Answer 12

Older Ethernet Standard, often using hubs, prone to collisions.

Question 13

What is a
a broadcast domain ?

Answer 13

Conceptual: Who hears the shout.

Concrete: The group of devices that receive a “Hey everyone!” message. Routers stop the shout; VLANs create separate “rooms” for shouting.

Question 14

Collision

Answer 14

When two or more nodes transmit simultaneously, signals interfere.

Question 16

Ethernet

Answer 16

Wired data sharing with collision control.

Question 17

What is 100BASE-TX?

Answer 17

Fast Ethernet (100 Mbps) using Cat 5 or better twisted pair cables.

Question 18

What does bandwidth refer to?

Answer 18

How much data can be sent at once.

Question 19

What is baseband?

Answer 19

A cable dedicated to one type of signal.

Question 20

What is CSMA/CD?

Answer 20

A method where devices listen before sending to avoid collisions. If a collision happens, they wait and try again.

Question 21

What is a hub?

Answer 21

A basic device that sends data to everyone connected, causing potential collisions and shared bandwidth.

Question 22

What is a switch?

Answer 22

A device that learns where each device is connected and sends data only to the right one, reducing collisions and giving each device its own bandwidth.

Question 23

What is a collision domain?

Answer 23

A section of the network where devices compete for the same ‘airtime’ to send data. Hubs create one big collision domain; switches break it up.

Question 24

What is autonegotiation?

Answer 24

Devices automatically agree on the fastest connection speed they can both use.

Question 25

What is legacy technology?

Answer 25

Older tech still used but replaced by faster standards.

Question 26

What is Fast Link Pulse?

Answer 26

An old signal for maintaining connections with older devices. Not needed with newer autonegotiation tech.

Question 28

What does switching between high and low voltages represent?

Answer 28

It represents digital bits (1’s & 0’s).

Question 30

What is 100BASE-TX?

Answer 30

A specific type of Fast Ethernet that provides 100 Mbps speed over twisted pair copper cables (Cat 5 or better).

Question 31

What does Mbps mean?

Answer 31

A measure of data transfer speed. 100 Mbps = 100 million bits per second.

Question 32

What does 'baseband' mean in 100BASE-TX?

Answer 32

The entire cable is dedicated to carrying only the Ethernet signal.

Question 33

What type of cable does 100BASE-TX use?

Answer 33

Twisted pair copper cable, like Cat 5. Twisting reduces interference.

Question 34

What is CSMA/CD?

Answer 34

A protocol used by 100BASE-TX to manage traffic. It 'listens' before 'talking' and handles collisions.

Question 35

What is a hub?

Answer 35

An older device that forwards data to all connected devices, creating a single collision domain and limiting network performance.

Question 36

What is a switch?

Answer 36

A device that learns which devices are connected to each port and sends data only to the intended recipient, creating separate collision domains and improving performance.

Question 37

What is a collision domain?

Answer 37

An area of the network where only one device can transmit at a time. Switches reduce collision domains.

Question 38

What is autonegotiation?

Answer 38

A feature that allows devices to automatically determine the fastest supported speed and mode (half- or full-duplex) and negotiate a compatible configuration.

Question 39

What is a Fast Link Pulse?

Answer 39

A signal that allows devices to check for compatibility.

Question 40

What does it mean for 100BASE-TX to be a legacy technology?

Answer 40

It's still used in older installations, but new networks typically use faster technologies.

Question 42

What is Gigabit Ethernet?

Answer 42

A standard providing 1,000 Mbps (1 Gbps) speed, requiring Cat 5e or better cabling and switches.

Question 43

What is 10 GbE?

Answer 43

Ethernet providing 10,000 Mbps (10 Gbps) speed. Can have reduced copper cable distances.

Question 44

What is 40 GbE?

Answer 44

Ethernet providing 40,000 Mbps (40 Gbps) speed.

Question 45

What is Cat 5e cable?

Answer 45

Enhanced Category 5 cable, required for Gigabit Ethernet over copper.

What is UTP?

Answer 46

A type of copper cable with twisted wires but no shielding.

Answer 47

A type of copper cable with twisted wires wrapped in foil for shielding.

What is S/FTP?

Answer 48

A type of copper cable with twisted and shielded wires for maximum interference protection.

Question 49

What is backbone cabling?

Answer 49

High-capacity connections between core network devices like switches and routers.

Question 50

What is Gbps?

Answer 50

A unit of measurement for data transfer rate. One gigabit is equal to 1,000,000,000 bits (one billion bits). So, 1 Gbps means one billion bits can be transmitted per second.
