1.2.1 Primary Storage (Memory)

• What is the primary function of primary storage in a computer system?

  Stores data and instructions
• ROM is volatile, meaning its data is lost when power is turned off.

  False
• Order the following features from fastest to slowest in terms of data access speed:

  1️⃣ Primary Storage (RAM)

  2️⃣ Primary Storage (ROM)

  3️⃣ Secondary Storage
• Primary storage provides quick access to information for immediate processing.
• Primary storage is slower but non-volatile compared to secondary storage.

  False
• Primary storage is volatile, meaning data is lost when power is off.
• RAM is non-volatile and retains data even when power is off.

  False
• Primary storage is non-volatile and retains data when power is off.

  False
• ROM is used to store boot-up instructions and is non-volatile.


  True
• RAM provides fast access to data but loses it when power is off.

  True
• ROM is non-volatile, meaning data persists even when power is off.


  True
• There are two main types of primary storage: RAM and ROM
• RAM is an example of volatile memory.
• What happens to data in primary storage when the computer is turned off?

  Data is lost
• Why is RAM considered volatile memory?

  Data is lost when power is off
• Match the storage type with its correct feature:

  Primary Storage ↔️ Volatile and fast

  Secondary Storage ↔️ Non-volatile and slow
• What is the typical usage of primary storage?

  Running applications
• How does RAM contribute to faster program execution?

  Fast data access
• What is primary storage used for in a computer system?

  Immediate processing
• What is the key difference between primary and secondary storage in terms of speed?

  Primary storage is faster
• What type of primary storage is used to store permanent data for boot-up instructions?

  ROM
• What is the key function of ROM in a computer system?

  Boot-up instructions
• What type of data is stored in RAM?

  Temporary data and instructions
• What is the primary use case for ROM in a computer system?

  Boot-up instructions
• Secondary storage is volatile and loses data when power is off.

  False
• What type of data does ROM store permanently?

  Boot-up instructions
• What are the two main types of primary storage?

  RAM and ROM
• What is the primary role of RAM in a computer system?

  Stores temporary data
• What type of data is stored in ROM during manufacturing?

  Boot-up instructions
• RAM is a type of primary storage that is volatile
• Secondary storage is used for long-term storage of files
• RAM enables fast data access for the CPU during program execution
• RAM is volatile, which means data is lost when power is off
