Denary (base 10)

• The standard numeral system used by humans, also known as the decimal system, which is based on ten symbols: 0-9.

• A numeral system that uses only two symbols: 0 and 1.

• A numeral system that is based on twelve symbols: 0-9 and A-B.

• A numeral system that uses Roman numerals for representation.

ROM

• Read-Only Memory, a type of non-volatile storage used to store firmware or software that is rarely changed.

• Random Access Memory, a type of volatile storage used for temporary data storage.

• Read-Only Memory, a type of volatile storage used for temporary data storage.

• Read-Only Memory, a type of non-volatile storage used for temporary data storage.

Image quality

• The clarity and detail of an image as determined by its resolution and color depth.

• The size of the image file measured in bytes.

• The speed at which an image is displayed on a screen.

• The type of software used to edit the image.

Virtual memory

• A technique that allows a computer to use more memory than is physically available by using disk space as an extension of RAM.

• A type of memory that is only accessible when the computer is connected to the internet.

• A hardware component that increases the speed of data processing in a computer.

• A method of storing data permanently on a hard drive.

Hexadecimal (base 16)

• A numeral system made up of 16 symbols (0-9 and A-F) used as a human-friendly representation of binary-coded values in computing and digital electronics.

• A numeral system that uses only two symbols (0 and 1) for binary representation.

• A numeral system that uses ten symbols (0-9) for decimal representation.

• A numeral system that uses eight symbols (0-7) for octal representation.

ASCII

• American Standard Code for Information Interchange

• Advanced Standard Code for Information Integration

• American Standard Code for Internet Interaction

• Automated Standard Code for Information Interchange

Solid state storage

• A type of volatile storage media that uses magnetic disks to store data.

• A type of non-volatile storage media that uses flash memory to store data, such as SSDs, which are faster and more reliable than traditional hard drives.

• A type of optical storage media that uses lasers to read and write data.

• A type of non-volatile storage media that uses tape to store data, which is slower than SSDs.

Magnetic storage

• A type of storage that uses magnetic media, such as hard drives, to store and retrieve data.

• A type of storage that uses optical media, such as CDs and DVDs, to store data.

• A type of storage that uses flash memory to store data.

• A type of storage that relies on cloud services to store data.

Optical storage

• A type of storage that uses magnetic fields to read and write data, such as hard drives.

• A type of storage that uses lasers and lights to read and write data, such as CDs, DVDs, and Blu-ray discs.

• A type of storage that relies on electrical charges to store data, such as flash drives.

• A type of storage that uses mechanical parts to read and write data, such as floppy disks.

Storage reliability

• The ability of a storage system to consistently perform its intended function without failure over a specified period.

• The maximum amount of data that can be stored in a system.

• The speed at which data can be read from or written to a storage device.

• The cost-effectiveness of a storage solution.
