Chapter 16 - Wide Area Networks (WAN)

Question 1

is a telecommunications network that extends across
large geographic areas, often spanning countries or continents.

Answer 1

Wide Area Networks (WAN)

Question 2

• A standardized wide area network (WAN) technology that provides high-speed data transmission by sending information in packets called frames.
• It operates at the data link layer (Layer 2) of the OSI model

Answer 2

FRAME RELAY

Question 3

are digital transmission standards used primarily for telecommunications and data communication networks.

Answer 3

E1 AND T1

Question 4

They are part of the T-carrier and E-carrier systems, which are used to transmit voice and data over digital lines.

Answer 4

E1 AND T1

Question 5

is a device that provides internet access by connecting to a cable television (CATV) network. It enables data transmission over the same coaxial cables that deliver cable TV services.

Answer 5

CABLE MODEM

Question 6

• a network technology designed for the high-speed transmission of data, voice, and video.
• It uses a connection-oriented approach, meaning it establishes a path between the source and destination before data transmission occurs.

Answer 6

ASYNCHRONOUS TRANSFER
MODE (ATM)

Question 7

type of DSL (Digital Subscriber Line) technology used to provide high-speed internet access over traditional telephone lines.

Answer 7

ASYMMETRIC DIGITAL
SUBSCRIBER LINE (ADSL)

Question 8

DSL

Answer 8

(Digital Subscriber Line)

Question 9

an advanced DSL technology that provides much higher data transfer rates compared to traditional DSL technologies like ADSL and SDSL.

Answer 9

VERY HIGH-SPEED DIGITAL
SUBSCRIBER LINE (VDSL)

Question 10

SDSL

Answer 10

SYMMETRIC DIGITAL
SUBSCRIBER LINE (SDSL)

Question 11

• a method of communication where a
  dedicated communication path or circuit is established between two parties for the
  duration of their conversation or data
  exchange.
• This path remains reserved and
  exclusive for the entire session.

Answer 11

CIRCUIT SWITCH

Question 12

a method of data transmission in which data
is broken down into small, discrete packets
that are sent independently through the
network.

Answer 12

PACKET SWITCH

Question 13

in networking generally refers to the rate at which
data is transmitted over a network or connection.

Answer 13

SPEED

Question 14

the physical pathways or channels used to transmit data and signals between devices
or network nodes.

Answer 14

TRANSMISSION MEDIA

Question 15

refers to the length over which data signals must travel from the source to the destination.

Answer 15

DISTANCE
