Question 1

A private internet that is used exclusively within an organization is called an intranet.

Accepted Answer

An intranet is a private network within an organization that uses internet technologies to facilitate communication and collaboration among employees. It is not accessible to the general public or external network.

Question 2

An internet is a network of networks that connects local area networks (LANs), wide area networks (WANs), and other internets.

Accepted Answer

An internet is a collection of interconnected networks that use standardized communication protocols to exchange data and information across the globe. It includes LANs, WANs, and other internets.

Question 3

Which wireless protocol is designed for transmitting data over short distances?

Accepted Answer

Bluetooth is a wireless protocol specifically designed for transmitting data over short distances, typically up to 30 feet. Optical fiber, a hop, and twisted-pair cable are not wireless protocols.

Question 4

A ________ is a networking device that detects the speed that a given device on a local area network (LAN) can handle and communicates with it at that speed.

Accepted Answer

A switch is the networking device that can detect the speed that a given device on a LAN can handle and communicates with it at that speed using a technology called auto-negotiation. A bus is a common pathway through which multiple devices communicate in a computer system. A domain is a group of computers and devices on a network that are administered as a unit with common rules and procedures. A hub is a networking device that connects multiple devices together and broadcasts data to all connected devices, causing potential data collisions and network congestion.

Question 5

Which of the following statements is TRUE of an Internet service provider (ISP)?

Accepted Answer

An ISP provides a legitimate Internet address and serves as a user's gateway to the Internet. While an ISP may use DSL technology to separate phone and computer signals, this is not the main function of an ISP. An ISP also facilitates two-way communication between a user's computer and the Internet, not just one-way. And while an ISP may use wireless technology, it is not required for communication through the Internet.

Question 6

Computers in two separate company sites must be connected using a(n) ________.

Accepted Answer

When computers in two separate company sites need to be connected, a wide area network (WAN) would be the most appropriate choice. This type of network allows for connection over a larger geographic area, such as between two different sites. Local area networks (LANs) are typically used within a single building or campus, so they would not be sufficient for connecting computers in two separate locations. A commerce server and Ethernet are both specific components or technologies that could be used within a LAN or WAN, but they do not encompass the entire network itself.

Question 7

Which protocol standard used for wired local area network (LAN) connections specifies hardware characteristics, such as the signal to be carried by each wire?

Accepted Answer

Ethernet is the protocol standard used for wired LAN connections and specifies the hardware characteristics, such as the signals to be carried by each wire. Bluetooth, WiMAX, and RuBee are wireless communication protocols and do not apply to wired LAN connections.

Question 8

A personal area network ________.

Accepted Answer

A personal area network, or PAN, is a network that connects devices located around a single person, typically within a range of about 30 feet. It is not a network that connects devices belonging to different people, nor does it have a minimum range of five miles. Additionally, while a PAN may be part of a larger network, it is not defined as a "network of networks."

Question 9

A private internet that is used exclusively within an organization is called a personal area network.

Accepted Answer

A personal area network (PAN) refers to a wireless network used for communication among personal devices within a short distance, such as a smartphone connecting to a smartwatch or a laptop connecting to a printer. A private internet used exclusively within an organization is typically called an intranet.

Question 10

Which of the following statements is TRUE of local area network (LAN) protocols?

Accepted Answer

IEEE LAN protocols typically begin with the numbers 802, with different suffixes indicating different types of LANs (e.g. 802.3 for Ethernet, 802.11 for Wi-Fi). Choice B is incorrect, as the IEEE 802.11 protocol is specifically for wireless LANs. Choice C is also incorrect, as wired LANs typically use Ethernet (IEEE 802.3) rather than Wi-Fi. Choice D is incorrect, as IEEE 802.3ac does not exist; there is an IEEE 802.11ac protocol for high-speed Wi-Fi, but it is not a standard for wireless LANs in general.

Question 11

What does the term 10/100/1000 Ethernet in most computer systems indicate?

Accepted Answer

The term 10/100/1000 Ethernet refers to the rate at which data can be transmitted on the network. It indicates the maximum speed at which data can be sent and received on the network, with 10 indicating 10 Mbps, 100 indicating 100 Mbps, and 1000 indicating 1 Gbps. This is important to consider when choosing network equipment and ensuring that the network is capable of handling the required data transfer speeds.

Question 12

Penelope's office uses a wired local area network (LAN) to connect its computers and printers over two floors. Which of the following protocols should it use for its LAN?

Accepted Answer

IEEE 802.3, also known as Ethernet, is the most common protocol used for wired LANs. It provides a reliable and fast connection between devices and is supported by most networking equipment. DSL, EVDO, and WiMAX are all wireless protocols and are not suitable for a wired LAN setup.

Question 13

The distinguishing characteristic of a local area network (LAN) is that it ________.

Accepted Answer

A local area network (LAN) connects computers at a single location, such as a home, office, or school. It does not connect computers at multiple locations or require a wired connection. A LAN is also not a network of networks, which would be a wide area network (WAN) or the internet.

Question 14

With a wide area network (WAN), an organization can place communications lines wherever it wants because all lines reside on its premises.

Accepted Answer

This statement is false. With a WAN, an organization can connect communications lines that span a large geographic area, potentially crossing multiple locations or even continents. These lines may be owned and operated by the organization, but they do not necessarily all reside on its premises.

Question 15

Which of the following protocols is commonly used for wireless local area networks (LANs)?

Accepted Answer

IEEE 802.11 is the protocol commonly used for wireless local area networks (LANs). Distributed Data Interface (DDI) is a legacy networking protocol used mainly in the 1980s and 1990s, while DSL (Digital Subscriber Line) is a technology used for high-speed internet access over traditional copper telephone lines. IEEE 802.3, also known as Ethernet, is a protocol commonly used for wired local area networks (LANs).

Question 16

A(n) ________ is a set of rules that programs on two communicating devices follow.

Accepted Answer

A protocol is a set of rules that programs on two communicating devices follow in order to communicate effectively. Domain refers to a specific area or topic, attribute refers to a characteristic or trait, and markup language is a way to format text and images on a webpage.

Question 17

A ________ is used to provide a seamless flow of data across networks.

Accepted Answer

A layered protocol, such as the TCP/IP protocol, is designed to provide a standardized approach to data transmission between devices on different networks. This allows for a seamless flow of data across different types of networks and ensures that data is transmitted reliably and efficiently. Databases, web pages, and web servers are all important components of network infrastructure, but they do not provide the same level of data transmission functionality as a layered protocol.
