Total questions: 10
Worksheet time: 5mins
Which of the following best describes a key difference between CISC and RISC processors?
CISC processors use fewer instructions, each performing simple tasks.
RISC processors use a small set of simple instructions, while CISC processors use a large set of complex instructions.
RISC processors are always slower than CISC processors.
CISC processors cannot be used in personal computers.
What is the main advantage of using multicore processors in computers?
They reduce the need for RAM.
They allow multiple tasks to be processed simultaneously, improving performance.
They make computers lighter in weight.
They increase the screen resolution.
Which of the following is a typical use for parallel systems?
Word processing
Weather forecasting simulations
Listening to music
Typing an email
In a RISC processor, instructions are generally designed to:
Complete complex tasks in a single instruction
Complete simple tasks quickly, often in a single clock cycle
Use as much memory as possible
Require multiple clock cycles for each instruction
Which of the following statements about CISC processors is correct?
They are designed to execute a small number of simple instructions.
They often have instructions that can perform multiple operations in one command.
They are never used in desktop computers.
They cannot support operating systems.
What does the term "parallel processing" refer to?
Running a single task on one processor core
Running multiple tasks at the same time using multiple processor cores
Using only one core for all tasks
Storing data in parallel lines
Which of the following is NOT a benefit of multicore processors?
Improved multitasking
Reduced power consumption per task
Increased physical size of the computer
Enhanced performance for certain applications
Why might a RISC processor be preferred in mobile devices?
They consume less power due to simpler instructions.
They require more cooling.
They are heavier.
They use more complex instructions.
Which of the following best describes a scenario where parallel systems are essential?
Calculating the total of a shopping list
Rendering high-resolution 3D graphics for films
Writing a letter
Checking the time
What is a common feature of CISC architecture?
Each instruction is executed in one clock cycle.
Instructions can perform several low-level operations, such as memory access and arithmetic, in a single instruction.
Only one instruction type is available.
It is only used in scientific calculators.
