    Which of the following prevents too much toner from sticking to the cylinder surface?

    • Scanning mirror

    • Control blade

    • Beam detect mirror

    • Developing cylinder

    Correct Answer
    A. Control blade
    Explanation
    The control blade prevents too much toner from sticking to the cylinder surface. It is responsible for regulating the amount of toner that is transferred onto the cylinder during the printing process. By controlling the thickness of the toner layer, the control blade ensures that an appropriate amount of toner is transferred onto the paper, resulting in clear and accurate prints.

    A twisted-pair cable that uses RJ-45 connectors has how many wires?

    • 2

    • 4

    • 8

    • 16

    Correct Answer
    A. 8
    Explanation
    A twisted-pair cable that uses RJ-45 connectors typically has 8 wires. The RJ-45 connector is commonly used for Ethernet connections, and it follows the TIA/EIA-568 standard, which specifies that the cable should have 4 pairs of wires. Each pair consists of a twisted pair of wires, resulting in a total of 8 wires in the cable.

    Which of the following protocols guarantees packet delivery?

    • TCP

    • UDP

    • IP

    • HTTP

    Correct Answer
    A. TCP
    Explanation
    TCP (Transmission Control Protocol) guarantees packet delivery because it is a reliable protocol that ensures the successful transmission of data by using acknowledgments and retransmissions. It establishes a connection between the sender and receiver, divides the data into packets, and ensures that all packets are received in the correct order without loss or duplication. TCP also includes error-checking mechanisms to detect and correct any errors that may occur during transmission. This reliability makes TCP suitable for applications that require guaranteed delivery, such as file transfer and email.

    Which of the following is the virtual memory swap file needed to booth Windows 2000/XP successfully?

    • Hall.dll

    • Kernel32.dll

    • Pagefile.sys

    • System

    Correct Answer
    A. Pagefile.sys
    Explanation
    The virtual memory swap file needed to boot Windows 2000/XP successfully is "Pagefile.sys". This file is used by the operating system as a form of virtual memory, allowing it to store data that cannot fit into physical RAM. It acts as an extension of the computer's memory, helping to improve system performance by temporarily storing data that is not actively being used.

    Which of the following terms refers to the process by which a signal weakens as it travels long distances over a network?

    • Amplifier repeater

    • Attenuation

    • Fade-out

    • Drop-down

    Correct Answer
    A. Attenuation
    Explanation
    Attenuation refers to the process by which a signal weakens as it travels long distances over a network. This can happen due to various factors such as resistance, interference, and dispersion. Amplifier repeater is not the correct answer as it refers to a device that boosts or amplifies a weak signal. Fade-out is also not the correct answer as it refers to a sudden loss of signal strength. Drop-down is not related to the weakening of a signal over a network.

    How many bits are in the SIMMs data path?

    • 16

    • 32

    • 64

    • 128

    Correct Answer
    A. 32
    Explanation
    SIMM stands for Single In-Line Memory Module, which is a type of computer memory module. The data path refers to the width of the memory bus, which determines the amount of data that can be transferred between the memory module and the processor in a single clock cycle. In this case, the correct answer is 32, indicating that the SIMMs data path is 32 bits wide. This means that it can transfer 32 bits of data at a time, allowing for faster data transfer and processing.

    The PCI Express bus currently comes in how many different slot sizes?

    • 1

    • 2

    • 3

    • 4

    Correct Answer
    A. 4
    Explanation
    The PCI Express bus currently comes in four different slot sizes. This means that there are four different physical sizes of slots available for PCI Express devices to be inserted into a computer's motherboard. These different slot sizes allow for flexibility in terms of the types of devices that can be connected to the PCI Express bus, accommodating various sizes and configurations of expansion cards.

    Which of the following symbols can be used as a wildcard character in a filename when working at the command prompt?

    • &

    • #

    • ?

    • @

    Correct Answer
    A. ?
    Explanation
    The symbol "?" can be used as a wildcard character in a filename when working at the command prompt. This symbol represents a single unknown character and can be used to match any character in a filename. For example, if you want to find all files that start with "file" and have a three-letter extension, you can use the wildcard pattern "file???.*" to match any three characters after "file".

    High-fidelity music CDs use how many bits in their sample size?

    • 8

    • 16

    • 32

    • 64

    Correct Answer
    A. 16
    Explanation
    High-fidelity music CDs use 16 bits in their sample size. The sample size refers to the number of bits used to represent each sample of the audio signal. In the case of CDs, each sample is represented by a 16-bit binary number, allowing for a wide dynamic range and high-quality audio reproduction. This sample size is capable of capturing a broad range of frequencies and nuances in the music, resulting in a more accurate and detailed sound reproduction.
