Acer Aspire 5315 is a popular laptop model that features the fast Intel Celeron processor and 2GB of computer memory. BIOS (Basic Input/Output System) stands for a special program (firmware) integrated into the computer motherboard. BIOS allows a user to configure hardware including, for example, a keyboard, hard and optical drives and to tweak certain system settings, such as the computer boot sequence.
