Which storage device uses flash memory to store data?

• HDD

• SSD

• Optical drive

• Magnetic tape

Answer explanation

The SSD (Solid State Drive) uses flash memory to store data, making it faster and more reliable than traditional HDDs, optical drives, and magnetic tape, which use different storage technologies.

What does HDD stand for?

• High Data Drive

• Hard Disk Drive (Correct)

• Host Digital Device

• Hybrid Data Device

Answer explanation

HDD stands for Hard Disk Drive, which is a data storage device that uses magnetic storage to store and retrieve digital information. The other options are incorrect and do not represent the standard definition of HDD.

What is the primary advantage of an SSD over an HDD?

• Lower cost per gigabyte.

• Higher storage capacity.

• Faster read and write speeds.

• Longer lifespan.

Answer explanation

The primary advantage of an SSD over an HDD is its faster read and write speeds, which significantly improve system performance and reduce load times compared to traditional hard drives.

Which interface is commonly used for connecting internal HDDs and SSDs to the motherboard?

• USB

• HDMI

• SATA

• Ethernet

Answer explanation

SATA (Serial ATA) is the standard interface used to connect internal HDDs and SSDs to the motherboard, providing faster data transfer rates compared to older interfaces. USB and HDMI are not used for this purpose.

What is the purpose of disk partitioning?

• To divide a physical drive into multiple logical drives.

• To increase the physical storage capacity.

• To improve network connectivity.

• To enhance graphics performance.

Answer explanation

The purpose of disk partitioning is to divide a physical drive into multiple logical drives, allowing for better organization, management, and utilization of storage space.

Which file system is commonly used by Windows operating systems?

• EXT4

• NTFS

• APFS

• HFS+

Answer explanation

NTFS (New Technology File System) is the primary file system used by Windows operating systems, providing features like security, compression, and large file support, unlike EXT4 (Linux), APFS (Apple), and HFS+ (older Apple).

What is the function of disk defragmentation?

• To erase all data on the drive.

• To compress files to save space.

• To organize fragmented files for faster access.

• To encrypt data for security.

Answer explanation

The function of disk defragmentation is to organize fragmented files on a drive, which allows for faster access and improved performance. This is essential for maintaining the efficiency of data retrieval.

Which storage device uses a laser to read and write data?

• Optical drive

• SSD

• HDD

• Flash drive

Answer explanation

An optical drive uses a laser to read and write data on discs like CDs, DVDs, and Blu-rays. In contrast, SSDs, HDDs, and flash drives use electronic methods for data storage.

What does RAID stand for?

• Redundant Array of Independent Disks

• Random Access Integrated Device

• Remote Application Interface Device

• Real-time Advanced Input Data

Answer explanation

RAID stands for Redundant Array of Independent Disks, which is a technology used to combine multiple disk drives into a single unit for improved performance and data redundancy.

Which RAID level provides disk mirroring for data redundancy?

• RAID 0

• RAID 5

• RAID 1

• RAID 10

Answer explanation

RAID 1 provides disk mirroring, meaning data is duplicated across two or more disks. This ensures data redundancy, as if one disk fails, the data remains accessible from the other disk(s).
