Question 1

The least expensive network to install is a ______.&#10;A)WAN&#10;B)LAN&#10;C)CT scanner&#10;D)MRI scanner

Accepted Answer

LAN (Local Area Network) is the least expensive network to install as it is limited in size and covers a small area such as a home, office or school. It requires less hardware and cabling as compared to WAN (Wide Area Network) which covers a larger geographical area such as multiple offices across cities or countries. CT scanner and MRI scanner are medical imaging devices and not related to computer networking.

Question 4

In which network type is each computer on the network considered equal?&#10;A)Server-based&#10;B)Client-based&#10;C)Peer-to-peer&#10;D)None of the above

Accepted Answer

In a peer-to-peer network, each computer is considered equal and has the same level of access to resources and information as the other computers on the network. In server-based networks, the server typically has more control and authority, while in client-based networks, the clients rely on the server to provide resources and information. None of the above is not a valid answer as it does not provide a correct option.

Question 6

Which of the following is considered a geographic category of networks?&#10;A)LAN&#10;B)CT scanner&#10;C)CR reader&#10;D)MRI scanner

Accepted Answer

LAN (Local Area Network) is a geographic category of network that connects devices in a limited geographical area such as a building, school, or campus. CT scanner, CR reader, and MRI scanner are all medical imaging equipment and not categorized as networks.

Question 7

The most fragile type of network connection is ______.&#10;A)Coaxial&#10;B)Twisted-pair&#10;C)Fiber optic&#10;D)Infrared

Accepted Answer

Fiber optic cables use thin glass fibers to transmit data using light signals. They are not susceptible to electromagnetic interference or signal loss over long distances, making them the most reliable and secure option for network connections. Coaxial and twisted-pair cables are more susceptible to interference and signal loss. Infrared connections are limited by line-of-sight and are not suitable for long-distance transmissions.

Question 8

Most network interface cards plug directly into the ______.&#10;A)CD drive&#10;B)Audio/video port&#10;C)USB port&#10;D)Motherboard

Accepted Answer

Network interface cards (NICs) are hardware components that connect a computer to a network. These cards are plugged directly into the motherboard of a computer, typically into a PCI (Peripheral Component Interconnect) slot. Therefore, the best choice is D) Motherboard.

Question 9

Which of the following describes a thin-client computer?&#10;A)Any computer that needs a server for task completion&#10;B)A computer that works independently of the network&#10;C)A computer that manages resources for other computers&#10;D)All of the above

Accepted Answer

A thin-client computer is a computer that relies on a server for task completion. It is designed to have minimal hardware and software capabilities and primarily functions as a terminal for accessing applications and data stored on a server. Therefore, option A is the correct choice as it defines a thin-client computer accurately. Option B is incorrect because a thin-client computer cannot function without connecting to a server. Option C is incorrect because a thin-client computer does not manage resources for other computers but rather relies on the server to manage resources.

Question 10

A server is ______.&#10;A)Any computer that needs a server for task completion&#10;B)A computer that works independently of the network&#10;C)A computer that manages resources for other computers&#10;D)All of the above

Accepted Answer

A server is a computer that manages resources for other computers. While any computer can benefit from a server, not all computers need or require one. Additionally, servers typically work as part of a network rather than independently. Therefore, the correct answer is C.
