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.
