Question 1

The M in MAN stands for multiple .

Accepted Answer

In the acronym MAN, referring to a Metropolitan Area Network, the "M" stands for "Metropolitan."

Question 2

LANs and WANs have roots in early telegraph and telephone systems.

Accepted Answer

LANs (Local Area Networks) and WANs (Wide Area Networks) trace their origins back to early communication systems, such as telegraph and telephone networks.

Question 3

After the Soviet's launched the Sputnik satellite into space, ARPA was formed to help reestablish the United States as a leader in science.

Accepted Answer

ARPA (Advanced Research Projects Agency) was formed in response to Sputnik and tasked with developing advanced technology for national security purposes, including space exploration. Its focus on research and development helped establish the United States as a leader in science and technology during the Cold War.

Question 4

In 1983 the separation of ARPANET and Milnet marked the arrival of the Internet.

Accepted Answer

The separation of ARPANET and Milnet in 1983 marked the transition from ARPANET to the modern internet.

Question 5

The Soviets launched the first communications satellite, called Echo.

Accepted Answer

The first communications satellite, called Telstar, was launched by the United States in 1962. Echo 1 and Echo 2, launched in 1960 and 1964 respectively, were passive satellites that reflected radio signals back to Earth.

Question 6

Which type of technology has advanced the fastest?
A)computer network communications
B)radio
C)television
D)telephone

Accepted Answer

Computer network communications have advanced at an unparalleled rate in recent years. The growth of the internet and the development of wireless communication technology have led to extremely fast advances in this area.

Question 7

LSI and VLSI chips paved the way for faster and cheaper digital devices, such as computers and computer terminals.

Accepted Answer

LSI (Large-scale integration) and VLSI (Very-large-scale integration) chips allowed for the creation of integrated circuits with a large number of transistors and components, resulting in faster and more powerful digital devices at a lower cost. This paved the way for the development of modern computers and computer terminals.

Question 8

EBCDIC consists of 96 uppercase and lowercase characters and numbers, plus 32 nonprinting characters.

Accepted Answer

EBCDIC (Extended Binary Coded Decimal Interchange Code) actually consists of a full byte 8-bit encoding scheme, which allows for 256 different characters, including uppercase and lowercase letters, numbers, symbols, and control characters, not just 128 as the statement suggests.

Question 9

Gateways are always stand-alone devices.

Accepted Answer

Gateways can be stand-alone devices, but they can also be integrated into other devices such as routers or firewalls.

Question 10

The W in WAN stands for wide.

Accepted Answer

WAN stands for Wide Area Network.

Question 11

TCP stands for Transmitted Configuration Protocol .

Accepted Answer

TCP stands for Transmission Control Protocol.

Question 12

Most of the first computer networks transmitted data over ____.
A)microwaves
B)radio waves
C)copper wire
D)fiber-optic media

Accepted Answer

Most of the first computer networks transmitted data over copper wire, specifically coaxial cables. Microwave and radio waves were later used for wireless communication, and fiber-optic media became popular in the 1980s.

Question 13

Bridges can be used to segment LANs into smaller subnetworks to improve performance by isolating network traffic, isolating network problems, and controlling access to each network.

Accepted Answer

Bridges can indeed be used to segment LANs into smaller subnetworks for the benefits mentioned.

Question 14

A single LAN may use only one protocol.

Accepted Answer

A LAN (Local Area Network) can use multiple protocols, such as TCP/IP, NetBIOS, and IPX/SPX. In fact, many LANs use a combination of different protocols to support various functions and applications.

Question 15

Routers are network transmission devices that connect different LANs or LAN segments using the same access methods.

Accepted Answer

Routers are devices that connect multiple networks together and can route packets between them, regardless of the access methods used by those networks.

Question 16

The simplest WAN is a dial-up modem connected to a network provider's services over basic telephone lines.

Accepted Answer

This is true. The simplest WAN is a dial-up modem connected to a network provider's services over basic telephone lines.

Question 17

Frames typically operate at the Network layer of the OSI model.

Accepted Answer

Frames operate at the Data Link layer of the OSI model.

Question 18

A(n)frame does not include routing information.

Accepted Answer

Frames contain only source and destination addresses, as well as the data payload, but not routing information. The routing is handled by the network layer protocols.

Question 19

Encoding involves converting a frame or packet from one format to another, as in formatting all frames or packets to the same size requirements regardless of the protocol.

Accepted Answer

Encoding refers to the process of converting data into a particular format for transmission or storage, not necessarily to formatting frames or packets to the same size. It involves transforming information into signals that can be transmitted over a communication medium or stored. Formatting frames or packets to the same size is a different concept related to data packaging rather than encoding.

Question 20

Often a LAN ends when there is a change in the communications medium.

Accepted Answer

A LAN (Local Area Network) typically ends at a point where the communication medium changes, such as transitioning from wired to wireless or connecting to a different type of network.
