OCR GCSE Computer Science: 1.1 Architecture (Part 3)

What units of measurement is CPU clock speed measured in?

• Hertz

• Bits

• Bytes

• Seconds

The higher the clock speed...

• The more instructions per second are processed

• The hotter the CPU will get

• The fewer instructions per second are processed

• The cooler the CPU will get

A CPU clocked at 1hz would...

• Process one instruction per second

• Process one hundred instructions per second

• Process one thousand instructions per second

• Process one million instructions per second

A CPU clocked at 2Ghz would...

• Process 2 million instruction per second

• Process 2 billion instructions per second

• Process 2 thousand instructions per second

• Process 2 hundred instructions per second

Modern typical Desktop, Notebook, and smartphone CPU clock speed is measured in...

• Gigahertz

• Megahertz

• Terahertz

• Kilohertz

What is a core?

• The central part of a CPU

• The central part of a Control Unit

• A discrete processing unit within a CPU

• The part of a CPU which does the calculations

Each core within a CPU has it's own...

• ALU

• Control Unit

• Registers
