Error Detection and Correction

Question 12

Regulates data flow between sender and receiver.

Answer 12

Flow Control

Question 13

a set of physical components that provide connectivity, security, routing management, access, and other integral features on a network.

Answer 13

Network Infrastructure

Question 14

refers to a single signal injection of the communication link.

Answer 14

Baseband

Question 15

is two or more signals on the same link often at different carrier frequencies

Answer 15

Broadband

Question 16

are the media over which data are transmitted to and from servers as well as to and from the other devices on the network.

Answer 16

Network Cables

Question 17

These are devices that connect multiple networks together and route data packets between them

Answer 17

Router

Question 18

isnetworking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

Answer 18

Network Switch

Question 19

a hardware deviceor software that processes requests sent over a network and replies to them.

Answer 19

Server

Question 20

the physical design of the network, along with hardware components such as cabling routers, switches, hubs, servers and workstations.

Answer 20

Physical Network Infrastructure

Question 21

They are devices that cannot decode the data packets received by them because they lack circuitry and logic to decode the data packets.

Answer 21

Hub

Question 22

is the part of the network which enables the users to connect to the wired Ethernet Network. It enables the users to share data and resources on the local network. The devices used in this layer includeEthernetSwitches and Hubs.

Answer 22

Access Layer

Question 23

When a network grows beyond a certain size, it must be divided into multiple local (Access Layer) networks. the distribution layer connects these networks together. It ensures that local traffic remains confined to local networks and governs traffic control between these networks.

Answer 23

Distribution Layer

Question 24

This layer is considered the backbone of a network, as it is used to connect multiple Distribution Layer devices together. This layer uses the most powerful devices to manage the traffic between the networks. The speed at which data flows in this layer is upwards of10 Gigabit Ethernet.

Answer 24

Core Layer

Question 25

Provides access points for hosts to connect to the network.

Answer 25

The Access Layer

Question 26

Acts as an intermediary between the Core Layer and the Access Layer, and keeps local traffic confined to local networks.

Answer 26

Distribution Layer

Question 27

Handles and transports huge amounts of data quickly and reliably, and connects multiple end networks together.

Answer 27

Core Layer

Question 28

mechanism through which routing information is exchanged between routers to determine the optimal path between network devices.

Answer 28

Dynamic Routing

Question 29

used to identify and announce network paths.

Answer 29

Dynamic Routing

Question 30

is an IP-based routing system that relies on manually configured routing tables to function.

Answer 30

Static Routing

Question 31

are routers that do not dynamically reroute traffic. Smaller networks with only several routers, or networks where security is a top priority

Answer 31

Static Routing
