    You are replacing a computer in an office. The existing computer has been connected to a TCP/IP network, and you want to use the existing network card in the new computer. Which of the following configuration settings would you have to set in the new computer? (Select three.)

    • Subnet Mask

    • IP Address

    • Network topology

    • Mac address

    • Default Gateway

    Correct Answer(s)
    A. Subnet Mask
    A. IP Address
    A. Default Gateway
    Explanation
    In order to use the existing network card in the new computer, the three configuration settings that need to be set are Subnet Mask, IP Address, and Default Gateway. The Subnet Mask is used to determine the network portion of an IP address, allowing the computer to communicate with other devices on the same network. The IP Address is the unique identifier assigned to the computer on the network. The Default Gateway is the IP address of the router or gateway device that allows the computer to communicate with devices on other networks. Network topology and Mac address are not configuration settings that need to be set in this scenario.

    Which of these offers the slowest transfer speed between a printer and a computer?

    • Parallel

    • Serial

    • USB

    • Network Printer

    Correct Answer
    A. Serial
    Explanation
    Serial offers the slowest transfer speed between a printer and a computer. Unlike parallel, USB, and network printer connections, serial connections transmit data one bit at a time, making them significantly slower. This is because serial connections use a single communication line to transfer data, while parallel connections use multiple lines to transfer data simultaneously, resulting in faster transfer speeds. USB and network printer connections also offer faster transfer speeds compared to serial connections due to their advanced technology and capabilities.

    • A laser outlines the image and burns a dark print (called a Positive) onto the page, which is then coated with toner.

    • A laser creates an electric image on the drum (called Registration), which attracts toner particles that are pressed onto the page.

    • A laser scans the image and burns toner into a dark print (called Registration), which is then pressed onto the page.

    • A laser burns toner into an image on the drum (called a Positive), which is then pressed onto the page.

    Correct Answer
    A. A laser creates an electric image on the drum (called Registration), which attracts toner particles that are pressed onto the page.
    Explanation
    A laser printer puts images on paper by creating an electric image on the drum, which is called Registration. This electric image attracts toner particles that are then pressed onto the page, resulting in the desired image.

    What is the purpose of the Transfer corona in the laser printer?

    • It transfers the ink to the paper

    • It charges the paper so the ink sticks to it

    • It moves the paper through the fusion rollers

    • It fuses the toner to the paper

    Correct Answer
    A. It charges the paper so the ink sticks to it
    Explanation
    The purpose of the Transfer corona in the laser printer is to charge the paper so that the ink sticks to it. This is an important step in the printing process as it ensures that the toner, which contains the ink, is effectively transferred from the drum to the paper. The charged paper attracts the toner particles, allowing for accurate and high-quality printing.

    You have installed two new 80GB hard disk drives in a Pentium II system that originally only had a 6.4GB drive. When you run FDISK to set up the drives, each is listed as only having 8.4GB capacity.

    • You incorrectly formatted the drives

    • Your BIOS doesnt support drives larger than 8.4GB

    • You need to enable LBA mode in the BIOS setup

    • You set the master/slave jumpers on the drive incorrectly

    • You are using a cable that in not compatible with the hard drive

    Correct Answer
    A. Your BIOS doesnt support drives larger than 8.4GB
    Explanation
    The correct answer is "Your BIOS doesn't support drives larger than 8.4GB." This means that the BIOS (Basic Input/Output System) of the Pentium II system is not capable of recognizing and utilizing hard drives with a capacity larger than 8.4GB. As a result, when FDISK is run to set up the new 80GB hard drives, they are incorrectly listed as having only 8.4GB capacity. To resolve this issue and fully utilize the capacity of the new drives, the user would need to update or upgrade the BIOS to a version that supports larger drives.

    Which of the following is true about installing DIMMs?

    • You must intall them in pairs

    • You insert them at a 35 degree angle then pop them into place

    • They are only installed in Laptops

    • You push the DIMMs straight down into the socket

    Correct Answer
    A. You push the DIMMs straight down into the socket
    Explanation
    The correct answer is that you push the DIMMs straight down into the socket. This is true for installing DIMMs in both desktop computers and laptops. DIMMs (Dual Inline Memory Modules) are the most common type of memory module used in computers, and they are inserted into the memory slots on the motherboard. To install a DIMM, you align the notch on the bottom of the module with the key in the memory slot, and then you apply even pressure to push the DIMM straight down until it clicks into place.

    At which clock speed should a Pentium 200 be run?

    • 200MHz

    • 133MHz

    • 233MHz

    • 266MHz

    Correct Answer
    A. 200MHz
    Explanation
    A Pentium 200 should be run at 200MHz because the clock speed of a processor determines how many instructions it can execute per second. In this case, the Pentium 200 is designed to run at a clock speed of 200MHz, meaning it can execute 200 million instructions per second. Running it at a lower or higher clock speed would result in decreased or increased performance, respectively. Therefore, to achieve optimal performance, the Pentium 200 should be run at its specified clock speed of 200MHz.
