What is a primary method used to detect errors during file opening in C? Checking if the file pointer is NULL Using a try-catch block Using a semaphore Checking the file size

Checking if the file pointer is NULL

Which method is effective for recovering from a failed binary file operation? Restart the entire application Reattempt the operation after a delay Switch to text file processing Ignore the error and continue

Reattempt the operation after a delay

What is the primary function of the CPU's control unit? Execute instructions Control data flow to peripherals Decode instructions and direct operations Perform arithmetic operations

Decode instructions and direct operations

In computer architecture, what is the role of the ALU? Manages input/output operations Controls instruction sequencing Performs arithmetic and logical operations Stores frequently accessed data

Performs arithmetic and logical operations

What is the purpose of a bus in computer architecture? To store instructions To connect the CPU to the display To transfer data between components To execute software programs

To transfer data between components

What is the function of the system bus in a computer system? Connects external peripherals Synchronizes the CPU clock Facilitates communication between the CPU and memory Executes software programs

Facilitates communication between the CPU and memory

Which of the following best describes pipelining in CPU architecture? Executing a single instruction at a time Overlapping the execution of multiple instructions Executing instructions in random order Performing logical operations sequentially

Overlapping the execution of multiple instructions

What distinguishes a multicore processor from a single-core processor? Each core has its own memory Multiple cores can execute instructions simultaneously It has a higher clock speed It uses less power than a single-core processor

Multiple cores can execute instructions simultaneously

Which of the following is a characteristic of Harvard architecture? Shared memory for instructions and data Separate memory for instructions and data Instructions and data are processed sequentially Data and instructions share the same bus

Separate memory for instructions and data

What is the primary function of the motherboard in a computer system? To provide power To connect and communicate between components To display output To store data

To connect and communicate between components

What is the primary purpose of a computer's power supply unit (PSU)? To store data To regulate temperature To convert AC power to DC power To increase processing speed

What is a stable sorting algorithm? An algorithm that maintains the relative order of equal elements An algorithm that minimizes time complexity An algorithm that uses minimal memory space An algorithm that sorts in descending order

An algorithm that maintains the relative order of equal elements

Which of the following is a feature of adaptive sorting algorithms? They take advantage of existing order in the data They are inherently unstable They always use additional memory They are slower on average than non-adaptive algorithms

They take advantage of existing order in the data

Why is Bubble Sort considered stable? It swaps adjacent elements only if they are out of order It uses a divide and conquer approach It is a non-comparison based algorithm It requires additional memory for sorting

It swaps adjacent elements only if they are out of order

What does 'adaptive' mean in the context of sorting algorithms? The algorithm adapts its behavior to improve efficiency based on the input data's existing order The algorithm changes the data type during sorting It means the algorithm can sort data of various types The algorithm uses a fixed sorting strategy regardless of input

The algorithm adapts its behavior to improve efficiency based on the input data's existing order

What is a key advantage of adaptive algorithms over non-adaptive ones? They can be more efficient with partially sorted data They always use less memory They are faster in all cases They produce more compact code

They can be more efficient with partially sorted data

Which of the following describes a non-adaptive sorting algorithm? Sorts data in a fixed manner without optimizing for pre-existing order Uses pre-existing order to improve efficiency Requires additional space proportional to input size Changes its sorting strategy based on input size

Sorts data in a fixed manner without optimizing for pre-existing order
