Answer
CPU/Processor: Servers typically use more powerful CPUs that can handle a greater number of simultaneous processes than standard PC processors.
Hard Drive/Storage: Servers often require larger and more reliable storage solutions, such as RAID systems, compared to standard PC hard drives.

Answer
Deletes Temporary Files: Disk clean-up removes temporary files that are no longer needed, freeing up valuable storage space.
Empties the Recycle Bin: This action permanently deletes items that are in the recycle bin, providing additional space by ensuring files are not just moved but completely removed.

Answer
Speed: Cache memory is faster than standard RAM, providing quicker access to frequently used data and instructions.
Capacity: Cache memory has a smaller capacity than standard RAM; it stores only the most recently used instructions while RAM stores a larger volume of data and programs.

Answer
Virtual memory is used when the physical RAM is full, allowing the operating system to use a portion of the hard drive as additional memory to temporarily hold data that isn’t actively being used.
Step 10
Explain the basic concepts of how virtual memory works.

Answer
Virtual memory works by using a section of the hard drive to simulate additional RAM, allowing the operating system to store data that would otherwise overflow from physical memory. It moves data back and forth between the RAM and the hard drive to ensure that active processes have the necessary memory available, enhancing multitasking capabilities.
