Question

Select and respond to one of the following claims regarding memory. Consider whether it is a valid claim. If it is, use an example to explain why. If it isn’t a valid claim, use a counterexample to explain why not. Finally, explain how understanding of the specific scenario you mentioned can aid in operating system design, implementation, and support.

• To avoid page space issues, it’s usually a good idea to allocate as much space as possible to virtual memory.
• Virtual memory is a hack; we should just increase the size of main memory and stop with this virtual memory foolishness.
• When a system slows down, increasing the amount of virtual memory is usually a good first step at fixing the issue.
• Memory management algorithms are not as useful as they could be because they assume a priori knowledge about process priority and memory requirements.

claim:When a system slows down, increasing the amount of virtual memory is usually a good first step at fixing the issue.

This is not a valid claim.if my system slows down increasing the virtual memory further decreases the performance

as swapping between hard drive(storage disk) is a costly operation .it is better approch if we increase the RAM rather than increasing the virtual memory.because virtual memory comes into picture only when my physical memory(RAM ) is running out of space.

virtaul memory can create a room for other priorty programs to run by degrading the performance.so if you think your computer performance got slow down here are the few tips whcih you can think off rather than going to increase the virtual memory.

1.disable auto start of application which you dont use frequently.

2 scan for viruses.

3 run the application which is your priority.uninstall rarely used application.

if you still find your system is slow go for increasing the RAM which definitly increase your system performance.
