Data storage：練習題

Which statement correctly describes how a Hard Disk Drive (HDD) stores and retrieves data?

An image is being stored with a resolution of \(1024 \times 512\) pixels and a colour depth of \(8\) bits. Calculate the file size of this image in mebibytes (MiB).

A 16-bit binary number is represented as 6AF3 in hexadecimal. What is the denary equivalent of this hexadecimal number?

Which type of primary storage is described as being non-volatile and is typically used to store the computer's start-up instructions (bootloader)?

Which technology is specifically used within Solid-State Drives (SSDs) to store data?

State the smallest unit of data storage in a computer system.

Explain why hexadecimal is commonly used to represent memory addresses or MAC addresses in computer systems, rather than binary.

Explain the operation of a Solid-State Drive (SSD) as a form of secondary storage, mentioning the technology it uses.

Explain the fundamental difference between primary storage and secondary storage in a computer system, and provide one specific example for each type.

A digital camera captures an image with a resolution of 1920 pixels by 1080 pixels and a colour depth of 24 bits. The image is uncompressed.

a) Calculate the uncompressed file size of this image in Bytes.

b) Convert the file size from part (a) into Kibibytes (KiB).

Show your working for both parts.
