  1. Encoding

  2. Storage

  3. Retrieval

  4. Forgetting
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Multiple choice

Which storage medium is generally considered the most reliable for long-term preservation of digital photographs?

  1. Hard disk drives

  2. Solid-state drives

  3. Optical discs (e.g., CDs, DVDs, Blu-ray discs)

  4. Magnetic tape
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Optical discs, such as CDs, DVDs, and Blu-ray discs, are generally considered more reliable for long-term preservation of digital photographs compared to hard disk drives, solid-state drives, and magnetic tape. They are less susceptible to data corruption and degradation over time, and they can be easily stored and transported.

Multiple choice

What is the most common type of memory used in digital computers?

  1. RAM

  2. ROM

  3. EEPROM

  4. Flash memory
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

RAM (Random Access Memory) is the most common type of memory used in digital computers. RAM is a volatile memory, which means that it loses its data when the power is turned off. RAM is used to store data that is being processed by the computer. ROM (Read-Only Memory) is a non-volatile memory, which means that it retains its data even when the power is turned off. ROM is used to store data that does not change, such as the computer's operating system.
