In a von Neumann architecture, what is the primary characteristic of the stored-program concept?

• Separate memory for data and instructions

• Centralized processing unit

• Interconnected processors

• Binary representation of data

What is the purpose of the Control Unit in a CPU?

• Execute arithmetic operations

• Manage input/output devices

• Control the flow of data between the CPU and memory

• Perform logic operations

In the MIPS instruction set, what does the "lui" instruction do?

• Load Upper Immediate

• Load Unsigned Immediate

• Left-Shift Unsigned Immediate

• Left-Shift Upper Immediate

What is the decimal equivalent of the binary number 1101?

• 11

• 13

• 15

• 17

What is the hexadecimal representation of the binary number 101110?

• 5A

• B6

• 2E

• 17

In the octal numbering system, what is the highest digit?

• 6

• 7

• 8

• 9

In shift left arithmetic (SLA), what happens to the leftmost bit during a shift?

• It is shifited into the rightmost position

• It is shifited out and lost

• It remains unchanged

• It is complemented

What is the key difference between shift left logical (SLL) and shift left arithmetic (SLA)?

• SLL fills vacated positions with zeros, while SLA fills with the sign bit

• SLL and SLA are synonymous, there is no difference

• SLL is used for integers, and SLA is used for floating-point numbers

• SLL is faster than SLA

In shift right arithmetic (SRA), how are the vacated positions filled when shifting a negative number?

• With zeros

• With the sign bit

• With ones

• It depends on the specific implementation

What does shift right logical (SRL) do with the leftmost bit during a shift?

• It is shifted into the rightmost position

• It is shifted out and lost

• It remains unchanged

• It is complemented
