A 2xx POST error code indicates a problem with: A. RAM or ROM B. hard drive C. system board D. second adapter card E. CMOS battery

The correct answer is: A. RAM or ROM

A 2xx POST error code indicates a problem with the RAM or ROM. The RAM is the computer’s main memory, and it is used to store data and instructions that the CPU needs to access quickly. The ROM is the computer’s permanent memory, and it contains the BIOS, which is the basic input/output system. The BIOS is responsible for initializing the hardware and loading the operating system.

If there is a problem with the RAM or ROM, the computer will not be able to start up properly. The POST error code will help you to identify the specific problem.

Here is a brief explanation of each option:

• RAM or ROM: The RAM is the computer’s main memory, and it is used to store data and instructions that the CPU needs to access quickly. The ROM is the computer’s permanent memory, and it contains the BIOS, which is the basic input/output system. The BIOS is responsible for initializing the hardware and loading the operating system.
• Hard drive: The hard drive is the computer’s primary storage device. It stores all of the data that the computer needs to access, including the operating system, applications, and user files.
• System board: The system board is the main circuit board in the computer. It contains the CPU, memory, and other essential components.
• Second adapter card: An adapter card is a circuit board that plugs into the system board and provides additional functionality to the computer. For example, a graphics card provides the computer with the ability to display images on a monitor.
• CMOS battery: The CMOS battery is a small battery that is used to power the BIOS. The BIOS is stored on a chip on the system board, and the CMOS battery keeps the BIOS powered on even when the computer is turned off.
