Unit 5

Question 1

This layer is also where you identify the interface between the data terminal equipment (DTE) and the data communication equipment (DCE).

Answer 1

Physical Layer

Question 2

is usually located at the service provider

Answer 2

DCE

Question 3

is the attached device

Answer 3

DTE

Question 4

DTE stands for

Answer 4

Data Terminal Equipment

Question 5

Two main types of Transmission Media

Answer 5

Guided Media
Unguided Media

Question 6

Requires Physical Medium

Answer 6

Guided Media Transmission Media

Question 7

Requires air for communication

Answer 7

Unguided Media Transmission Media

Question 8

Functions as a multi-port repeater, reamplifying and forwarding incoming digital signals to all connected ports without examining the data.

as a result all devices within share the same collision and broadcast domains.

Answer 8

Hub

Question 9

is the type of topology a hub creates where the hub is a central device and cables extend in all directions out from it

Answer 9

physical star network

Question 10

What kind of topology do Ethernet networks run

Answer 10

bus topology

Question 11

type of network topology where the signal has to run through the network from end to end.

Answer 11

bus topology

Question 12

Different types of Topology

Answer 12

Bus Topology
Ring Topology
Star Topology
Mesh Topology
Hybrid Topology

Question 13

Types of Topology

every workstation is connected to a single cable, meaning every host is directly connected to every other workstation in the network.

Answer 13

bus topology

Question 14

Types of Topology

computers and other network devices are cabled together in a way that the last device is connected to the first to form a circle or ring

Answer 14

ring topology

Question 15

Types of Topology

Common Ethernet physical layout where a central switch connects devices. Physical connection is commonly made using twisted-pair wiring.

Answer 15

Star Topology

Question 16

Types of Topology

All devices cabled together with connection to each other, redundant links for self-healing & reliability. Physical connection through Fiber/twisted-pair wiring.

Answer 16

Mesh Topology

Question 17

Types of Topology

Ethernet uses a physical star layout (cables come from all directions), and the signal travels end-to-end, like a bus route

Answer 17

Hybrid Topology

Question 18

communicates directly with communication media. Media types vary, using audio tones or voltage transitions. Protocols describe necessary bit patterns, encoding, and media interface qualities for different media types (video, text, audio)

Answer 18

Physical layer
