Understanding Memory Management

What are the two main types of memory in computers?

• Cache memory and flash memory

• Primary memory and secondary memory

• Static memory and dynamic memory

• Volatile memory and non-volatile memory

What is the purpose of RAM in a computer?

• To manage the power supply of the computer.

• To increase the computer's internet speed.

• To permanently store the operating system files.

• The purpose of RAM in a computer is to provide temporary storage for data and instructions that the CPU needs for quick access and processing.

What is the difference between static and dynamic memory allocation?

• Static memory allocation can be resized during program execution.

• Dynamic memory allocation is fixed at compile time.

• Static memory allocation is flexible and occurs at runtime.

• Static memory allocation is fixed at compile time, while dynamic memory allocation is flexible and occurs at runtime.

What does virtual memory allow a computer to do?

• Store data permanently on the hard drive.

• Extend available memory by using disk space.

• Allow multiple users to access the same memory space.

• Increase processing speed by using more RAM.

What is a memory leak?

• A memory leak occurs when too much memory is allocated at once.

• A memory leak is the process of compressing data in memory.

• A memory leak is the failure to release memory that is no longer needed.

• A memory leak is a type of computer virus.

How can memory leaks affect a computer's performance?

• Memory leaks can significantly slow down a computer's performance by exhausting available memory resources.

• Memory leaks only affect the speed of internet connections.

• Memory leaks improve a computer's performance by freeing up resources.

• Memory leaks have no impact on a computer's performance.

What is cache memory used for?

• Cache memory is used to improve the speed of data access for the CPU.

• Cache memory is used to increase the size of the hard drive.

• Cache memory is used to cool down the CPU.

• Cache memory is used for long-term data storage.

How does cache memory improve speed?

• Cache memory slows down data retrieval by increasing latency.

• Cache memory stores all data permanently for future access.

• Cache memory improves speed by providing faster access to frequently used data and instructions.

• Cache memory only works with external storage devices.

What is the role of the operating system in memory management?

• The operating system allocates, tracks, and manages memory for processes, ensuring efficient and safe memory usage.

• The operating system is responsible for user interface design.

• The operating system only manages hardware resources.

• The operating system does not interact with memory at all.

Why is it important to manage memory effectively in computers?

• It is important to manage memory effectively to optimize performance, ensure resource utilization, prevent memory leaks, and maintain system stability.

• Memory management is only important for gaming computers.

• Memory management only affects the speed of the CPU.

• Effective memory management is not necessary for modern operating systems.
