  • RAM modules are inserted into these slots and clipped into place for secure installation. They are aligned by notches that prevent incorrect installation.

Other sections:

  • Section A: This is the CPU power connector area where the main power for the motherboard is connected.
  • Section B: This area represents the input/output (I/O) ports for peripherals like USB, HDMI, and Ethernet.
  • Section D: This is the PCIe slots area, used for installing components like graphics cards or network interface cards.

2. Which three components are usually installed on a PC motherboard before the motherboard is installed in the computer case? (Choose three.)

  • CPU
  • CPU heatsink and fan
  • RAM
  • internal hard drives
  • power supply
  • optical drive
  • adapter cards

The three components that are usually installed on a PC motherboard before the motherboard is installed in the computer case are:

  1. CPU
    • The processor is installed into the CPU socket on the motherboard before mounting the motherboard in the case. This ensures proper alignment and minimizes the risk of damage to the delicate CPU socket pins during installation.
  2. CPU Heatsink and Fan
    • The CPU cooler (heatsink and fan) is typically attached to the CPU after it is installed. This allows proper thermal paste application and ensures the cooling solution is securely mounted. It is easier to install the heatsink and fan outside the case due to limited space in most cases.
  3. RAM
    • RAM modules are installed into the DIMM slots on the motherboard before mounting it in the case. This is because it requires a bit of force to properly insert the RAM sticks, and it is easier to do this outside the case where space is not constrained.

Explanation for Other Components:

  • Internal Hard Drives: These are installed in the drive bays of the case, not on the motherboard.
  • Power Supply: This is mounted inside the computer case and connected to the motherboard afterward.
  • Optical Drive: Similar to hard drives, optical drives are installed in the case, not on the motherboard.
  • Adapter Cards: These (e.g., graphics cards) are typically installed after the motherboard is mounted in the case to avoid damage during installation and allow for proper alignment with the case’s expansion slots.

Pre-installing the CPU, CPU cooler, and RAM ensures a more manageable and error-free assembly process.

3. Which component requires a technician to install screws externally through the PC case?

  • RAM
  • CPU
  • motherboard
  • power supply

The correct answer is power supply.

Explanation:

The power supply unit (PSU) is installed by securing it to the PC case using screws that are inserted externally through the back of the case. This ensures the PSU is firmly mounted and aligned with the case openings for power cable access.

Why not the other options?

  • RAM: RAM modules are installed directly into the motherboard’s DIMM slots and do not require screws.
  • CPU: The CPU is inserted into the motherboard’s CPU socket and secured with a locking mechanism, not screws.
  • Motherboard: The motherboard is secured internally to the case using standoffs and screws, but these are installed from inside the case, not externally.

The power supply is the only component that requires external screws for installation.

4. What is a good safety precaution to take when opening a computer case?

  • Place tape over the case edges that are sharp.
  • Remove the cover (or door) of the computer case before installing or removing parts.
  • Remove the connections to the front panel before extending the case fully open.
  • Ensure that any loose clothing such as a tie or shirt stay in constant contact with the case when handling internal components.

The correct answer is:

Place tape over the case edges that are sharp.

Explanation:

When working inside a computer case, sharp edges can pose a safety hazard. Placing tape over these edges helps prevent cuts and injuries. This is a practical safety precaution to take when handling or working on internal components.

Why not the other options?

  • Remove the cover (or door) of the computer case before installing or removing parts: While this is necessary for accessing internal components, it is not a “safety precaution” but a standard procedural step.
  • Remove the connections to the front panel before extending the case fully open: This is unnecessary and could risk damaging front panel cables. Proper care can be taken without disconnecting these cables unless absolutely required.
  • Ensure that any loose clothing such as a tie or shirt stays in constant contact with the case when handling internal components: This is unsafe. Loose clothing should be secured to avoid it catching on components or causing accidents. Proper grounding (such as using an anti-static wrist strap) is a better safety measure.

Focusing on safe handling and taking precautions against sharp edges is key when working with computer hardware.

5. Which statement describes the proper use of an anti-static wrist strap?

  • An anti-static wrist strap should not be used in conjunction with an antistatic mat.
  • For optimum grounding, the clip should be attached to a painted section of the computer case.
  • An anti-static wrist strap should make contact with the skin.
  • The anti-static wrist strip should not be attached to any grounded object.

The correct answer is:

An anti-static wrist strap should make contact with the skin.

Explanation:

  • An anti-static wrist strap prevents the build-up of static electricity, which can damage sensitive computer components. For it to work effectively, the metal part of the strap must make direct contact with the skin to properly ground the person wearing it.

Why not the other options?

  1. “An anti-static wrist strap should not be used in conjunction with an anti-static mat.”
    • This is incorrect. An anti-static wrist strap can and should be used in conjunction with an anti-static mat for optimal protection against electrostatic discharge (ESD).
  2. “For optimum grounding, the clip should be attached to a painted section of the computer case.”
    • This is incorrect. The clip should be attached to an unpainted, bare metal part of the computer case or another grounded object. Painted surfaces can insulate the clip and prevent proper grounding.
  3. “The anti-static wrist strap should not be attached to any grounded object.”
    • This is incorrect. The strap needs to be attached to a grounded object to safely dissipate static electricity.

Proper use of an anti-static wrist strap ensures that static electricity does not harm sensitive electronic components during handling or installation.

6. Which statement describes the purpose of an I/O connector plate?

  • It connects the PCIe adapter slots used for video directly to the CPU for faster processing.

The correct answer is:

It makes the I/O ports of the motherboard available for connection in a variety of computer cases.

Explanation:

The I/O connector plate, also known as the I/O shield, is a removable metal plate that fits into the back of the computer case. It provides cutouts that align with the I/O ports on the motherboard, such as USB ports, audio jacks, Ethernet ports, and more. This ensures that the ports are accessible and properly aligned when the motherboard is installed in the case.

Why not the other options?

  1. “It plugs into the motherboard and expands the number of available slots for adapter cards.”
    • This describes an expansion card, not the I/O connector plate.
  2. “It provides multiple connections for SATA hard drives to connect to the motherboard.”
    • SATA connectors are located on the motherboard itself, and the I/O connector plate is unrelated to this functionality.
  3. “It connects the PCIe adapter slots used for video directly to the CPU for faster processing.”
    • PCIe slots are directly integrated into the motherboard and have no connection to the I/O connector plate.

The primary purpose of the I/O connector plate is to facilitate the alignment and accessibility of the motherboard’s input/output ports.

The shown slot’s length and design confirm it as a PCIe x16 slot.

8. A technician is installing additional memory in a computer. How can the technician ensure that the memory is correctly aligned?

  • A notch in the memory module should be aligned with a notch in the memory slot.
  • The label on the memory module should always face the CPU.
  • The arrows on the memory module should be aligned with the arrows on the motherboard slot.
  • Memory slots are color coded, so the red memory module should be aligned with the blue memory slot.

The correct answer is:

A notch in the memory module should be aligned with a notch in the memory slot.

Explanation:

  • Memory modules (such as DIMMs for desktop PCs) are designed with a notch that matches the keyed notch in the memory slot on the motherboard. This ensures that the module can only be inserted in the correct orientation.
  • If the module is not aligned correctly, it will not fit into the slot, preventing improper installation and potential damage.

Why not the other options?

  1. “The label on the memory module should always face the CPU.”
    • This is incorrect because memory orientation depends on the motherboard design, not the position of the CPU.
  2. “The arrows on the memory module should be aligned with the arrows on the motherboard slot.”
    • Memory modules and slots do not have arrows for alignment.
  3. “Memory slots are color-coded, so the red memory module should be aligned with the blue memory slot.”
    • While memory slots are sometimes color-coded for dual-channel configurations, this has nothing to do with the physical alignment of the memory module in the slot.

Always align the notches to ensure the memory module is installed correctly and securely.

27. Why are e-readers commonly preferred over tablets to read books?

  • An e-reader only supports Wi-Fi connectivity, but a tablet can support both Wi-Fi and cellular connectivity.
  • An e-reader commonly has longer battery life than a tablet device.
  • A tablet device usually weighs less than an e-reader.
  • A tablet uses an electronic paper technology that provides better performance than an e-reader.

The correct answer is:

An e-reader commonly has longer battery life than a tablet device.

Explanation:

E-readers are designed specifically for reading and use electronic paper technology (e-ink displays), which consumes very little power compared to the LCD or OLED screens used in tablets. This allows e-readers to have significantly longer battery life, often lasting weeks on a single charge, compared to tablets that typically last only hours or a day with active use.

Why not the other options?

  1. “An e-reader only supports Wi-Fi connectivity, but a tablet can support both Wi-Fi and cellular connectivity.”
    • This is incorrect because some e-readers also support cellular connectivity, depending on the model.
  2. “A tablet device usually weighs less than an e-reader.”
    • This is not true. E-readers are generally lighter than tablets, making them more portable and easier to hold for long periods.
  3. “A tablet uses an electronic paper technology that provides better performance than an e-reader.”
    • This is incorrect. Tablets use LCD or OLED displays, which are not as suitable for long reading sessions as the e-ink displays of e-readers. E-ink screens reduce eye strain and provide a paper-like reading experience, especially in bright light.

Summary:

E-readers are commonly preferred over tablets for reading books because they offer much longer battery life, are lighter, and use e-ink technology that is easier on the eyes for extended reading sessions.

28. What are three features of GPS on mobile devices? (Choose three.)

  • phone number lookup
  • navigation
  • specialized search results
  • device tracking
  • remote wipe
  • gas mileage calculations

The three correct features of GPS on mobile devices are:

  1. Navigation
    • GPS is primarily used for navigation, providing turn-by-turn directions and real-time positioning for driving, walking, cycling, or other travel modes.
  2. Specialized Search Results
    • GPS enables location-based services, such as providing search results relevant to the user’s current location (e.g., nearby restaurants or gas stations).
  3. Device Tracking
    • GPS allows mobile devices to be tracked in real-time, which is useful for finding lost devices, enabling services like “Find My Device” or tracking family members.

Why not the other options?

  1. Phone number lookup
    • GPS does not provide functionality for looking up phone numbers. This feature is unrelated to GPS.
  2. Remote wipe
    • Remote wipe is a security feature that allows a user to erase device data remotely. While GPS may assist in locating the device, it is not responsible for the wiping functionality itself.
  3. Gas mileage calculations
    • While GPS can track distances traveled, gas mileage calculations depend on additional data like fuel consumption, which GPS alone does not provide.

Summary:

The correct features of GPS on mobile devices are navigation, specialized search results, and device tracking, all of which rely on location-based capabilities provided by GPS technology.
