Every NIC is embedded with a unique address that consists of a 12-digit hexadecimal value. What is this address called?
Correct Answer
C. MAC address
Explanation
Every NIC (Network Interface Card) is embedded with a unique address called the MAC address. This address consists of a 12-digit hexadecimal value and is used to identify the NIC on a network. The MAC address is assigned by the manufacturer and is unique to each NIC, allowing for the proper routing of data packets within a network. The subnet mask, IP address, and default gateway are all related to network configuration and routing, but they are not the unique address embedded in the NIC.

File and printer sharing for Microsoft networks is an example of a network protocol.
Correct Answer
B. False
Explanation
File and printer sharing for Microsoft networks is not a network protocol, but rather a feature or service that allows users to share files and printers over a network. Network protocols, on the other hand, are a set of rules and conventions that govern how data is transmitted and received over a network.

What is one of the disadvantages of a peer-to-peer network compared to a server-based network?
Correct Answer
C. Limited security
Explanation
One of the disadvantages of a peer-to-peer network compared to a server-based network is limited security. In a peer-to-peer network, each device is responsible for its own security measures, making it more vulnerable to security breaches. Unlike a server-based network, where security measures can be centralized and managed more effectively, a peer-to-peer network lacks the same level of control and protection. This can result in increased risks of unauthorized access, data breaches, and other security threats.

Each component of a computer is designed to perform only one specific task—either input, processing, or output.
Correct Answer
B. False
Explanation
This statement is false because each component of a computer is not designed to perform only one specific task. In fact, many components can perform multiple tasks. For example, a processor can handle both input and processing tasks, while a monitor can handle both output and input tasks (in the case of touchscreens). Therefore, the components of a computer are not limited to just one specific task.

You are building a gaming computer and you want to install a dedicated graphics card that has a fast GPU and 1GB of memory onboard. You need to make sure that you have the right connector available on your motherboard. What type of connector would be appropriate?
Correct Answer
D. PCI-Express
Explanation
PCI-Express would be the appropriate connector for installing a dedicated graphics card with a fast GPU and 1GB of memory onboard. PCI-Express is the most common and widely used interface for connecting graphics cards to motherboards. It provides high-speed data transfer and is specifically designed to handle the demands of modern graphics processing. IDE, PCI, and SATA are not suitable connectors for graphics cards as they are primarily used for other purposes such as connecting hard drives or expansion cards.
6.
When data is being prepared for transmission onto the network, it is broken into small pieces and a header and trailer are added to each piece to help identify it. What is this process called?
Correct Answer
C. Encapsulation
Explanation
The process described in the question, where data is divided into smaller pieces and a header and trailer are added to each piece for identification purposes, is called encapsulation. This process ensures that data is organized and can be properly identified and reconstructed when transmitted over a network. Verification, application, and multitasking are unrelated to this specific process.

The XYZ company has two offices, one downtown, and a brand new office in the newer section of town. To connect the two offices, they will need a dedicated line, probably leased from the local phone company. What type of network will they be implementing to connect their two offices?
Correct Answer
C. MAN
Explanation
The correct answer is MAN, which stands for Metropolitan Area Network. A MAN is a type of network that covers a larger geographic area than a LAN (Local Area Network) but smaller than a WAN (Wide Area Network). In this case, the two offices of the XYZ company are located in the same city or metropolitan area, so a MAN would be the appropriate network type to connect them.
8.
What is one of the disadvantages of a server-based network compared to a peer-to-peer network?
Correct Answer
D. Additional costs
Explanation
A server-based network requires the setup and maintenance of dedicated servers, which can lead to additional costs for purchasing, installing, and maintaining the servers. In contrast, a peer-to-peer network does not require dedicated servers, as each device can act as both a client and a server. This eliminates the need for additional hardware and associated costs.
9.
Which of the following are examples of input devices? (Choose all that apply.)
Correct Answer(s)
A. Mouse
C. DVD
D. Scanner
Explanation
The mouse, DVD, and scanner are all examples of input devices. A mouse allows the user to interact with the computer by moving the cursor and clicking on items. A DVD drive can read information from a DVD and input it into the computer. A scanner can convert physical documents or images into digital files that can be inputted into the computer. On the other hand, a monitor and printer are output devices, as they display or produce information from the computer.
10.
What command would you issue from a command prompt to see a listing of the computers in your workgroup?
Correct Answer
C. Net view
Explanation
The correct answer is "net view". This command is used to see a listing of the computers in your workgroup. It displays a list of all the computers that are currently connected to the same workgroup as your computer.
