The CPU

How would you describe what the CPU does?

• To process instructions and data

• To process only instructions or data but not both

• To make sure the computer turns on and loads correctly

• To load Google classroom and connect to the Internet

The basic operation of a CPU is called the :

• Fetch Decode Execute Cycle (FDE)

• Turn-on Work Turn-off Cycle (ToWTo)

• Startup Process Shutdown Cycle (SPS)

• All of these

What is connected to the CPU and is shown in the block diagram? Tick the correct answers

• Input

• Internet

• Storage

• USB

• Output

RAM is generally:

More than one answer, select the correct ones

• faster than storage devices

• slower than storage devices

• larger in size than hard drives

• smaller in size than hard drives

• temporary memory

ROM is generally:

More than one answer, select the correct ones

• permanent memory

• larger in size than RAM

• smaller in size than storage

• used to help to computer to start

• able to store your work

When we update certain types of ROM we __________ the firmware.

• scratch

• flash

• uplink

• veto

• grab

The CPU ____________ the first instruction in the list before anything else.

• drops

• fetches

• calculates

• encrypts

• encodes

The CPU decoder:

• interprets an instruction and passes it on.

• fetches the instruction from memory and passes it on.

• loads a program from the hard drive so you can use it.

• performs calculations on the instructions and data.

The speed of a computer depends mainly on:

Tick the correct answers

• Clock speed

• Internet connection

• Number of cores

• Amount of cache

• How much it costs

If 1 Hertz (Hz) is one instruction per second, how may instructions per second is 1 Megahertz (MHz)?

• ten (10)

• 1 billion (1,000,000,000)

• 1 million (1,000,000)

• 1 thousand (1000)

• 1 trillion (1,000,000,000,000)
