Question 28: What does a "guard bit" contribute to in floating-point arithmetic?

Increasing data precision

Tracking the exponent value

Improving rounding accuracy

Reducing memory use

Question 30: What term describes a branch that causes the program counter to move to a new address?

Branch taken

Branch not taken

Control hazard

Conditional loop

Question 31: What does "pipelining" allow a CPU to do with instructions?

Execute each instruction fully before starting the next

Overlap instruction execution stages

Avoid branch instructions

Fetch data from cache

Question 32: What operation does the logical OR perform in binary logic?

Outputs 1 only if both inputs are 1

Outputs 0 if either input is 0

Outputs 1 if at least one input is 1

Outputs the opposite of the input

Question 33: In assembly language, what term refers to an instruction representation close to machine code?

High-level language

Binary code

Assembly language

Bytecode

A modern CPU register

A high-level language instruction

An archaic term for a register

An I/O device

Question 38: In a multiprocessor system, what does "weak scaling" measure?

Speed-up with increased problem size proportional to processors

Constant-speed improvement with fixed problem size

Cache efficiency across processors

Question 39: What is the primary role of "control" in a CPU?

Executes arithmetic operations

Directs data flow according to program instructions

Manages user input/output

Operates as the main memory

Question 40: Which memory type is volatile and requires periodic refreshing to retain data?

DRAM

Flash memory

Cache memory

EEPROM
