1. Two types of auxiliary storage devices often used on personal computers are __________.

Keyboards and scanners

USB flash drives and hard disks

Monitors and printers

Control units and arithmetic logic units

USB flash drives and hard disks are commonly used as auxiliary storage devices on personal computers. These devices provide additional storage space for users to save and access their files and data. USB flash drives are portable and can be easily connected to a computer's USB port, allowing for easy transfer of files between devices. Hard disks, on the other hand, are internal or external storage devices that offer larger storage capacities and are commonly used for long-term data storage. Both USB flash drives and hard disks are essential for expanding the storage capabilities of personal computers.

6. One billion bytes is called a __________, and typical hard disk sizes range from 160 to 750 billion bytes.

Kilobyte (KB)

Megabyte (MB)

Gigabyte (GB)

Dekabyte (DB)

One billion bytes is equal to a gigabyte (GB). This is a commonly used unit of digital storage capacity. Typical hard disk sizes range from 160 to 750 billion bytes, which is equivalent to 160 to 750 GB. Kilobyte (KB) is a smaller unit of storage capacity, equal to 1,000 bytes. Megabyte (MB) is larger than a kilobyte, equal to 1 million bytes. Dekabyte (DB) is not a recognized unit of digital storage capacity.

7. The process of loading the operating system into the computer's memory from auxiliary storage is called ________.

Loading

Booting

Driving

Saving

Booting is the correct answer because it refers to the process of loading the operating system into the computer's memory from auxiliary storage. This process initializes the computer's hardware, starts the operating system, and prepares the computer for use. Loading, driving, and saving do not accurately describe this specific process.
