Q

When attempting to improve system performance for Linux computers with a limited amount of memory, why is increasing the size of the swap file system not considered the best solution?

A

A swap file system uses hard disk space to store inactive RAM content. (The swap file system is used by Linux when it runs out of physical memory. When needed, the kernel moves inactive RAM content to the swap partition on the hard disk. Storing and retrieving content in the swap partition is much slower than RAM is, and therefore using the swap partition should not be considered the best solution to improving system performance.)

Q

A user calls the help desk reporting that a laptop with Linux freezes on startup and displays kernel panic. What could cause this problem?

A

A driver has become corrupted. (A corrupted driver or failing hardware could cause kernel panic for Linux or Mac OS. The laptop will not be able to boot successfully. Either GRUB or LILO corruption or GRUB or LILO deletion would cause the stop screen to display a “Missing GRUB” or “Missing LILO” message. A resource unavailable to an application will cause the application to stop responding, but not prevent a laptop from starting up.)
