Correct Answer: A
A device driver is specialized system software that enables the operating system to communicate with and control specific physical devices.
Q482.L1 cache is _____?
Correct Answer: C
L1 cache (Level 1) is the fastest cache memory, integrated directly inside the CPU processor silicon for ultra-low latency access.
Q483.Which of the following is NOT a computer operation?
Correct Answer: B
Computers execute mechanical instructions (input, output, processing, storage) but do not possess independent consciousness or biological 'thinking' abilities.
Q484.Which of the following is NOT true about ROM?
Correct Answer: B
ROM (Read-Only Memory) is non-volatile, retaining its stored boot firmware permanently even when the computer system is completely powered down.
Q485.A computer that processes information in trillions of instructions per second is called ______?
Correct Answer: A
Supercomputers represent the most powerful category of processors, built specifically to run trillions of instructions and complex model calculations per second.
Q486.What is the report object in MS Access used for?
Correct Answer: C
Reports in Microsoft Access are designed specifically to organize, format, display, and print data extracted from database tables or queries.
Q487.Memory management helps to improve the?
Correct Answer: C
Memory management refers to optimizing physical RAM (Main Memory) allocation across running processes to maintain system speed and prevent resource depletion.
Q488.What is true about a master document?
Correct Answer: A
A master document acts as a central control document that compiles and manages links to a series of individual subdocuments.
Q489.NVIDIA is famous for _____?
Correct Answer: C
NVIDIA is world-renowned as the pioneering designer of GPUs (Graphics Processing Units), heavily used in gaming, rendering, and AI computing.
Q490.Computer memory that needs its data to be refreshed otherwise it losses data is?
Correct Answer: B
DRAM (Dynamic RAM) utilizes capacitors that leak charge, requiring constant electrical refreshing cycles to preserve stored data bits.

Q493.The halting problem is a decision problem related to program ______?
Correct Answer: B
The Halting Problem (formalized by Alan Turing) is the decision problem of determining whether a program will terminate (halt) or execute infinitely.
Q494.In a flowchart, a parallelogram represents which of the following operations?
Correct Answer: C
In flowcharts, a parallelogram represents input (e.g., entering data) or output (e.g., printing or displaying results) operations.
Q495.In Scratch programming, an event is best described as an action that the program _____?
Correct Answer: B
In Scratch, an event (like clicking a green flag or a sprite) is an action that triggers specific scripts and forces the program to respond.
Q496.In signal transmission, which hardware process is used to counteract attenuation over long distances?
Correct Answer: B
Amplification increases the signal's strength or amplitude to prevent data degradation or loss (attenuation) as it travels through transmission media.
Q497.Which specialized computer utility is responsible for combining compiled object files into a single, runnable executable program?
Correct Answer: C
A Linker merges individual compiled object files (.obj) and external library files to resolve references and produce a final executable (.exe).
Q498.Because a computer can both read data from and write data to Random Access Memory (RAM), RAM is also referred to as ______ memory.
Correct Answer: B
RAM allows the system to read existing data from memory addresses and write new data back to them, making it Read/Write memory.
Q499.What is the primary function of the Arithmetic Logic Unit (ALU) within a computer system processor?
Correct Answer: B
The ALU handles mathematical operations (addition, subtraction) and logical operations (AND, OR, NOT, comparisons) on binary numbers.
Q500.Which of the following statements best describes the Object-Oriented Programming (OOP) concept of Polymorphism?
Correct Answer: B
Polymorphism (meaning 'many forms') allows methods to behave differently based on the object executing them, as seen in overriding.
