82. When installing a new video card in a system which previously used an onboard video controller, the onboard video controller needs to be:

Correct Answer: Correct answer is: (B) Disable in the BIOS.

Exam Relevance: CompTIA A+, CCNA, ITIL Foundation

Difficulty: Moderate

Concept notes: The BIOS (Basic Input/Output System) is the firmware that initializes and tests system hardware components and establishes communication between the operating system and the hardware. Disabling the onboard video controller in the BIOS ensures that the system uses the new video card instead of the onboard video controller.

Common Mistakes: A common mistake is to think that the onboard video controller can be disabled through the operating system or the new video card itself, rather than through the BIOS.

Explanations: The onboard video controller must be disabled in the BIOS to prevent conflicts with the new video card. The BIOS settings allow the user to configure hardware settings, including disabling onboard components. Disabling the onboard video controller in the BIOS ensures that the system will use the new video card exclusively, avoiding potential conflicts or performance issues.

Option Analysis:

Option A: Disabling the onboard video controller in the Windows Control Panel is not effective because the Control Panel does not have the capability to disable hardware at the BIOS level.
Option B: Disabling the onboard video controller in the BIOS is the correct approach as it directly configures the hardware settings to prioritize the new video card.
Option C: Physically removing the onboard video controller is not feasible because it is integrated into the motherboard and cannot be removed without damaging the motherboard.
Option D: Disabling the onboard video controller using a jumper pin on the new video card is not a standard procedure and would not affect the onboard video controller's functionality.

Mnemonic: BIOS: Basic Input/Output System

83. A logic error

Correct Answer: Correct answer is: (D) Is when the program is coded incorrectly to produce an incorrect result, but with correct statements. The only way to know there was an error is to notice that the result is wrong.

Exam Relevance: ACM, GRE Computer Science, Programming Competitions

Difficulty: Moderate

Concept notes: A logic error occurs when the program's code is syntactically correct but produces incorrect results due to flawed logic.

Common Mistakes: Students often confuse logic errors with syntax errors, which are mistakes in the code's structure or grammar.

Explanations: A logic error is a type of error where the program's code is syntactically correct but the logic is flawed, leading to incorrect results. Unlike syntax errors, which are detected by the compiler or interpreter, logic errors can be harder to identify because the program runs without crashing. The only way to detect a logic error is by observing that the output is incorrect.

Option Analysis:

Option A: This describes a runtime error, not a logic error.
Option B: This describes a syntax error, not a logic error.
Option C: This is an incorrect and humorous description, not a logic error.
Option D: This correctly describes a logic error.

This is in contrast to a Sequential File, which requires reading from the beginning to access a specific record. The index in a Random File provides a mapping of record keys to their physical locations, enabling efficient random access.

Option Analysis:

Option A: Correct. A file organized via an index is known as a Random File.
Option B: Incorrect. A Master File is a primary file that contains the main data, not necessarily organized via an index.
