Understanding CPU Cores and Processors

What is a core in simple terms?

• A part of the motherboard

• A complete copy of the CPU

• A type of memory

• A graphics processing unit

How many separate processing units does a quad-core processor have?

• Two

• Three

• Four

• Eight

Which of the following is NOT a component of a CPU core?

• Registers

• Accumulators

• ALU

• RAM

Does doubling the number of cores in a CPU simply double the overall speed?

• Yes

• No

Why doesn't doubling the number of cores double the speed?

• Cores do not need to communicate

• Many programs are not designed to use multiple cores

• More cores always slow down the CPU

• Cores are identical

What is the role of communication between CPU cores?

• It speeds up processing

• It takes time and can affect performance

• It is unnecessary

• It only occurs in single-core processors

What is the GCSE specification regarding CPU cores?

• It requires knowledge of multi-core communication

• It does not require detailed knowledge of multi-core processors

• It focuses on graphics processing units

• It includes advanced CPU architecture

What is the common misconception about a physical chip with more than one core?

• It is always called a CPU

• It is always called a GPU

• It is always called RAM

• It is always called a motherboard

What is the technically correct term for a chip with more than one core?

• CPU

• Multi-core processor

• Single-core processor

• RAM

What is an ALU in the context of a CPU core?

• Arithmetic Logic Unit

• Advanced Learning Unit

• Automated Logic Unit

• Arithmetic Learning Unit
