CompTIA Hardware Practice Test #1

Question 1

What kind of connector is often used to transfer electricity from a PC's power supply to an internal hard drive, CD or DVD drive?

Accepted Answer

Molex

Answer

A Molex connector is a legacy power connector commonly used in older PCs to supply 12V and 5V power to internal components. It was primarily utilized for IDE hard drives, CD/DVD drives, and some case fans before the widespread adoption of SATA power connectors. While less common in modern systems, it's still found in many existing computers and power supplies.

Question 2

Which of the following statements best defines RAID 10?

Accepted Answer

RAID 10 offers data redundancy as well as quicker performance.

Answer

RAID 10 (also known as RAID 1+0) is a nested RAID level that combines the mirroring of RAID 1 with the striping of RAID 0. This configuration provides both excellent data redundancy, as data is mirrored across pairs of drives, and significantly improved performance due to data striping across multiple disk sets. It requires a minimum of four disks to implement.

Question 3

Your manager has requested that you bring him a DE-15 connection. Which of the following does he mean?

Accepted Answer

VGA

Answer

The DE-15 connector, often referred to as a D-sub 15-pin connector, is the standard connector for Video Graphics Array (VGA) analog video signals. It is commonly used to connect computer monitors to video cards or other display devices. When a manager requests a DE-15 connection, they are referring to a VGA cable or port.

Question 4

Which of the following choices incorrectly defines the functionality of parity RAM or parity memory?

Accepted Answer

Parity RAM has the ability to self-correct identified errors.

Answer

Parity RAM is designed to detect single-bit errors in memory by adding an extra 'parity' bit to each byte. If an error is detected, the system will typically report the error or halt operation to prevent data corruption. However, parity RAM does not have the capability to self-correct these identified errors; that functionality is provided by more advanced Error-Correcting Code (ECC) RAM.

Question 5

What kind of connector with 40 pins is utilized for internal hard drives?

Accepted Answer

IDE

Answer

Integrated Drive Electronics (IDE), also known as Parallel ATA (PATA), is an older interface standard used for connecting storage devices like hard drives and optical drives to a computer's motherboard. IDE cables are typically wide ribbon cables with 40 pins, distinguishing them from the smaller, newer SATA connectors. This interface was a standard for internal hard drives for many years.
