A technician is installing a new power supply in a computer. Which type of power connector should be used to connect wa CD-ROM
Correct Answer
C. Molex
Explanation
The correct answer is Molex. Molex connectors are commonly used to provide power to various components in a computer, including the CD-ROM drive. They have multiple pins and a secure locking mechanism, ensuring a reliable connection. The Berg connector is typically used for floppy disk drives, the Mini-Molex connector is used for small peripherals, and the 20-pin ATX connector is used for connecting the power supply to the motherboard.

A technician is installing a new power supply in a computer. Which type of power connector should be used to connect to an ATX motherboard?
Correct Answer
D. 20-pin connector
Explanation
The correct answer is the 20-pin connector. This type of power connector is specifically designed to connect to an ATX motherboard. It provides the necessary power to the motherboard and ensures proper functionality. The other options listed, such as Berg, Mini-Molex, and Molex, are not compatible with an ATX motherboard and should not be used for this purpose.

When a technician installs a new CPU, what will help maintain even contact and heat distribuition between the CPU and heat sink?
Correct Answer
D. Thermal Compound
Explanation
Thermal compound is used to maintain even contact and heat distribution between the CPU and heat sink. It is a heat-conductive paste that fills in microscopic imperfections on the surfaces of the CPU and heat sink, ensuring maximum thermal transfer. This helps to prevent hot spots and keeps the CPU cool, improving its performance and longevity. Silicon spray, graphite paste, and glue are not suitable for this purpose and may cause damage or poor heat dissipation.
4.
When installing a CPU in a ZIF socket, how should the technician align the pins to avoid damage?
Correct Answer
B. Pin 1 on the CPU is aligned with Pin 1 on the ZIF socket
Explanation
When installing a CPU in a ZIF socket, the technician should align Pin 1 on the CPU with Pin 1 on the ZIF socket. This ensures that the CPU is inserted correctly and prevents any damage that could occur if the pins are not properly aligned.

A technician is installing additional memory in a computer. How can the technician guarantee that the memory is correctly aligned?
Correct Answer
B. A notch in the memory module should be aligned with a notch in the memory slot.
6.
When mounting a motherboard in a computer case, what does the technician use to prevent the motherboard from touching the bottom off the case
Correct Answer
A. Standoffs
Explanation
When mounting a motherboard in a computer case, technicians use standoffs to prevent the motherboard from touching the bottom of the case. Standoffs are small metal or plastic spacers that are screwed into the case, creating a gap between the motherboard and the case. This is important because direct contact between the motherboard and the case can cause electrical shorts and damage the components. By using standoffs, the motherboard is securely elevated and protected, ensuring proper functioning of the computer.
7.
When installing a adapter card in a computer, how should a technician properly secure the card?
Correct Answer
D. Install the card, and secure it to the case with a screw
Explanation
The correct answer is to install the card and secure it to the case with a screw. This is the proper way to secure an adapter card in a computer. Attaching the card to the expansion slot using thermal paste or attaching it to the motherboard using thermal pads are not correct methods of securing the card. Metal retaining clips located on the expansion slots are not used to secure the card, but rather to hold it in place once it is properly secured with a screw.

Which two connectors are used to connect external peripherals
Correct Answer(s)
D. PS/2
E. USB
Explanation
PS/2 and USB are the two connectors used to connect external peripherals. PS/2 is a connector that is commonly used for connecting keyboards and mice to a computer. USB, on the other hand, is a universal connector that can be used to connect a wide range of peripherals such as printers, scanners, external hard drives, and more. Both connectors provide a reliable and efficient way to connect external devices to a computer, allowing for seamless communication and data transfer.
