Quick Questions

Shade in the A or B circle for each question.

1. What is a microprocessor?

A A very small complete computer with RAM and storage inside

B A CPU built as an integrated circuit on a single chip

2. Which statement about a microprocessor is correct?

A It is an integrated circuit

B It is a type of secondary storage

3. How many chips does a microprocessor use for the whole CPU?

A A single chip

B Many separate chips joined by wires

4. Is a microprocessor the same thing as the whole computer?

A No, it is only the processor part

B Yes, it includes the RAM, storage and screen

5. Where can you find a microprocessor?

B In a PC, a smartphone and a washing machine

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1microprocessor		AA microprocessor is built as one integrated circuit on a single chip, not many separate chips.
2integrated circuit		BA CPU built as an integrated circuit on a single chip
3A microprocessor is only the processor, not the whole computer, because RAM, storage and input/output devices are separate		CA microprocessor is only the CPU on a single chip. RAM, storage and the screen are separate parts, so it is not the whole computer.
4Microprocessors are found in PCs, phones and embedded devices such as washing machines		Dmicroprocessor -> PC, phone, washing machine
5A microprocessor is the whole computer in one box, including RAM, storage and screen		Emicroprocessor != computer
6A microprocessor is made of many separate chips wired together on a board		FA tiny set of electronic components etched onto one piece of silicon, the form a microprocessor takes

Answer Key

Microprocessor

Section A: Quick Questions

B — A CPU built as an integrated circuit on a single chip

A — It is an integrated circuit

A — A single chip

A — No, it is only the processor part

B — In a PC, a smartphone and a washing machine

Section B: Match the Pairs

microprocessor → A CPU built as an integrated circuit on a single chip

integrated circuit → A tiny set of electronic components etched onto one piece of silicon, the form a microprocessor takes

A microprocessor is only the processor, not the whole computer, because RAM, storage and input/output devices are separate → microprocessor != computer

Microprocessors are found in PCs, phones and embedded devices such as washing machines → microprocessor -> PC, phone, washing machine

A microprocessor is the whole computer in one box, including RAM, storage and screen → A microprocessor is only the CPU on a single chip. RAM, storage and the screen are separate parts, so it is not the whole computer.

A microprocessor is made of many separate chips wired together on a board → A microprocessor is built as one integrated circuit on a single chip, not many separate chips.

Section C: Definitions

microprocessor — A CPU built as an integrated circuit on a single chip. It is only the processor, not the whole computer, and is found in PCs, phones and embedded devices.

Section D: Fill in the Blanks

CPU on one chip = microprocessor

microprocessor = integrated circuit CPU

microprocessor = CPU on a single chip

microprocessor != whole computer

Found in: PCs, phones, embedded devices

Section E: Spot the Error

B — A microprocessor is a CPU built on a single chip, so chips should be 1, not 5.

B — A microprocessor is only the processor, not the whole computer. is_whole_computer should be False.

D — Microprocessors are found in PCs, phones and embedded devices such as microwaves. A paperclip has no microprocessor.

D — If the CPU is not on a single chip, the part is not a microprocessor, so the function should return False.

A — A microprocessor is a CPU on a chip, so cpu_on_chip should be True.
