Which of the following statements accurately describes CISC processors?

• CISC processors execute each instruction with one clock cycle.
• CISC processors have complex instructions built directly into the hardware.
• CISC processors require separate codes for load and store instructions.
• CISC processors need more RAM to store more instructions.

What is a key characteristic of RISC architecture?

• RISC instructions closely resemble commands in high-level languages.
• RISC processors have complex instructions built directly into the hardware.
• RISC processors can execute a series of operations in one instruction.
• RISC requires the compiler to do more work to convert high-level languages into instruction code.

In RISC architecture, how is instruction execution typically structured?

• RISC architecture does not require a compiler.
• Each instruction is executed with one clock cycle.
• Instructions can execute multiple operations simultaneously.
• Instructions are executed in batches.

Which of the following best describes the need for separate codes in RISC architecture?

• RISC does not require any coding.
• RISC uses a single code for all instructions.
• RISC requires separate codes for load and store instructions.
• RISC combines load and store instructions into one code.

Which of the following statements about RISC processors is true?

• RISC processors do not require a compiler.
• RISC processors can execute complex instructions in one cycle.
• RISC processors require fewer transistors due to simpler instructions.

What is the relationship between the number of cores in a processor and processing speed?

• More cores can improve processing speed by handling tasks simultaneously.
• The number of cores does not affect processing speed.
• Fewer cores are always more efficient than more cores.
• More cores generally lead to slower processing speeds.

What is a significant advantage of multi-core processors?

• They are less efficient than single-core processors.
• They can have more than two processing units.
• They can only run one program at a time.
• They require more RAM than single-core processors.

What is a primary benefit of using multi-core processors in computing?

• They allow for parallel processing of tasks.
• They simplify the programming process.
• They can only run one application at a time.
• They eliminate the need for RAM.

How does parallel processing enhance computing performance?

• It allows multiple cores to run the same program in less time.
• It limits the number of programs that can run simultaneously.
• It reduces the need for RAM in processing tasks.
• It requires complex instructions to be executed.
