Computer Memory Quiz L4-7

What is the primary function of RAM in a computer system?

• Stores permanent instructions

• Stores instructions for the CPU to execute temporarily

• Stores data permanently

• Transfers data between different components

Which type of memory is non-volatile?

• RAM

• Cache

• ROM

• Registers

What characteristic distinguishes solid-state drives (SSDs) from traditional magnetic drives?

• Faster read/write speeds

• Cheaper cost per GB

• Higher capacity

• Use of optical lasers for data storage

Which type of storage is most susceptible to data loss due to physical damage?

• Solid-state storage

• Optical storage

• Magnetic storage

• RAM

Why is cache memory important in a computer system?

• It provides large storage capacity

• It stores frequently used instructions for faster access by the CPU

• It is cheaper than main memory

• It increases the durability of the computer system

What does the term 'clock speed' refer to in the context of CPUs?

• The number of cores a CPU has

• The speed at which a CPU executes instructions

• The amount of cache memory in a CPU

• The power usage of a CPU

Which of the following is a characteristic of magnetic storage?

• Uses lasers to read and write data

• Infinitely rewritable

• Expensive per GB

• No moving parts

What are the key disadvantages of cloud storage?

• Relies on internet connection and carries security risks

• Expensive and has low capacity

• Requires high power consumption

• Prone to physical damage

Why do SSDs tend to degrade over time?

• They are affected by magnetic fields

• They have a limited number of read/write cycles

• They are prone to physical wear

What advantage does level 1 cache (L1) have over level 3 cache (L3)?

• Higher capacity

• Closer proximity to the CPU, allowing faster data access

• Slower, but stores more data

• Acts as secondary storage
