What is the primary goal of an operating system?

• Run applications faster.

• Manage system resources.

• Create a beautiful user interface.

• Connect to the Internet.

Which type of scheduling determines which process is brought into main memory?

• Short-term scheduling.

• Medium-term scheduling.

• Long-term scheduling.

• No scheduling type.

What is swapping used for?

• Increasing CPU speed.

• Freeing up main memory by moving inactive processes to disk.

• Protecting memory from unauthorized access.

• Managing I/O devices.

What is a TLB (Translation Lookaside Buffer)?

• A type of read-only memory.

• A cache for page table entries.

• A process scheduling algorithm.

• A virtual memory management technique.

What happens when a page is not found in main memory?

• The system crashes.

• A page fault occurs.

• The page is automatically loaded from the cache.

• The process is terminated.

What is a virtual address?

• The actual address of physical memory.

• A logical address generated by the CPU.

• The address used by I/O devices.

• The address stored in the TLB.

In memory management, what problem does paging help solve?

• External fragmentation.

• Increasing memory access speed.

• Reducing the size of the page table.

• Protecting memory from being overwritten.

How does the FIFO page replacement algorithm work?

• Replaces the least recently used page.

• Replaces the page that has been in memory the longest.

• Replaces the page with the highest address.

• Replaces the page with the lowest address.

Which of the following methods is NOT used for memory management?

• Fixed partitioning.

• Dynamic partitioning.

• Paging.

• Object-oriented programming.

How many entries does an inverted page table have?

• One entry per process.

• One entry per virtual page.

• One entry per real memory page frame.

• One entry per I/O device.
