When you do need to upgrade a system BIOS?

• Whenever you install a new hard disk drive

• Whenever a BIOS update provides functionality that is not currently supported, but is required by the operating system or hardware

• Whenever the BIOS settings need to be modified

• Supports drives larger than 2.2 TB

What is the name for the routine that tests the motherboard, memory, disk controllers, video, keyboard and other system hardware?

• CSST

• POST

• CMOS

• BIOS

What is the role of the CMOS in a modern computer?

• Test the hardware during system setup

• Coordinate the use of system hardware with the OS

• Saves information about system devices like the real-time system clock

• Loads the operating system into memory

This RAM is typically used in cache memory, like CPU cache

• SRAM
• DRAM

This RAM is more complex and fast and less dense, less power

• SRAM

• DRAM
