Question 5

What is the typical size of an access router?
A) About the size of a hardback book
B) About the size of a pack of cards
C) Approximately the size of a laptop computer
D) Approximately the size of three or four hardback books

Accepted Answer

Access routers are typically about the size of a hardback book, making them compact enough to fit comfortably on a desk or shelf without taking up too much space.

Question 6

In a home network, a message sent by a PC is called a ________.
A) server
B) byte
C) frame
D) router

Accepted Answer

In a home network, a message sent by a PC is encapsulated into a format known as a frame. This format is used for network communications at the data link layer.

Question 7

In a typical home network, an access router connects the home network to ________.
A) an intranet
B) the Internet
C) a LAN
D) a WAN

Accepted Answer

An access router connects the home network to the Internet, allowing devices within the home to access online resources and services.

Question 8

For a host on a home network to use the Internet, each host needs a(n) ________.
A) switch
B) NAT
C) IP address
D) DHCP

Accepted Answer

For a host on a home network to use the Internet, it needs an IP address. This is because the Internet is based on the IP protocol, and every device that communicates over the Internet must have a unique IP address to identify it.

Question 9

Which of the follow is FALSE about access routers?
A) They all have an SPI firewall.
B) They provide network address translation.
C) They connect a network to another network.
D) They have a DHCP server.

Accepted Answer

Not all access routers come with an SPI (Stateful Packet Inspection) firewall. While many modern routers include various forms of firewall protection, including SPI, it is not a universal feature across all access routers.

Question 10

UTP is a ________.
A) type of router
B) network interface card
C) type of wiring
D) type of translation

Accepted Answer

UTP stands for Unshielded Twisted Pair, which is a type of wiring used in networking to connect different devices.

Question 11

Which of the following is a type of twisted pair wiring?
A) STP
B) NAT
C) IP
D) DHCP

Accepted Answer

STP, which stands for Shielded Twisted Pair, is a type of twisted pair wiring used in telecommunications and network cabling to reduce electromagnetic interference.

Question 12

Companies use carriers for WAN transmission because ________.
A) companies lack rights of way
B) they are less expensive than a LAN
C) companies can then employ fewer computer security personnel
D) it is not legal to have carriers of their own

Accepted Answer

Companies use carriers for WAN (Wide Area Network) transmission primarily because they lack the rights of way to lay down their own network infrastructure over long distances, which would involve negotiating access over private and public lands.

Question 13

DARPA created ________.
A) home networks
B) the Internet
C) intranets
D) WANS

Accepted Answer

DARPA (Defense Advanced Research Projects Agency) played a key role in the development of the Internet, originally through the ARPANET project, which was the precursor to the modern Internet.

Question 14

Initially, only ________ could connect to the Internet.
A) large corporations
B) noncommercial networks
C) commercial networks
D) K-12 schools

Accepted Answer

Initially, the Internet was primarily used by academic, research, and government institutions, not for commercial purposes. It was designed to facilitate information sharing and communication among these noncommercial networks.

Question 15

Messages that travel within a single network are called ________.
A) packets
B) switches
C) frames
D) core switches

Accepted Answer

Messages that travel within a single network are encapsulated in a format known as frames. Frames are the data units used at the Data Link layer (Layer 2) of the OSI model, which is responsible for node-to-node delivery of data within the same network.

Question 16

Messages that travel all the way from one computer to another across the Internet are called ________.
A) packets
B) switches
C) frames
D) core switches

Accepted Answer

Packets are the units of data that are transmitted over the Internet. When a file or other data is sent from one computer to another, it is broken down into smaller units called packets, which are then reassembled into the original file by the receiving computer.

Question 17

An internal TCP/IP internet for a company's own communication is known as a(n) ________.
A) Internet
B) ISP
C) intranet
D) LAN

Accepted Answer

An intranet is a private network that uses TCP/IP, internet technologies, and protocols to share information, operational systems, or computing services within an organization. This differentiates it from the Internet, which is a public network.

Question 18

Internet service providers connect at centers that are usually called ________.
A) NAPs
B) PSDNs
C) switches
D) LANs

Accepted Answer

NAPs, or Network Access Points, are key internet infrastructure locations where ISPs (Internet Service Providers) connect with each other to exchange traffic. This allows for efficient data routing between different networks.

Question 19

Networking circuitry is usually a component that you can choose to add to your circuit board in most PCs.

Accepted Answer

Networking circuitry, such as Ethernet or Wi-Fi adapters, is typically integrated into the motherboard of modern PCs, making it a standard feature rather than an optional add-on.

Question 20

A home network needs an Internet access line to connect to the Internet.

Accepted Answer

A home network requires an Internet access line, such as DSL, cable, or fiber, to connect to the Internet. This line provides the physical or wireless connection to the Internet Service Provider (ISP), enabling devices on the network to access online resources.
