QR Challenge: Computer Basics Vocabulary

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

Questions / Answers (teacher reference)

Question	Answer
1. 1. Machine that performs 4 basic functions: input, processing, storage, and output.	Computer
2. 2. Physical parts of the computer that you can see and touch.2	Hardware
3. 3. The programs or other "instructions" that a computer needs to perform specific tasks. Examples include Microsoft Office, web browsers, or any other program/application installed on the computer.3	Software
4. 4. The main body or brain of a computer, also called the system unit. Consists of a plastic or metal enclosure, the motherboard (main circuit board), and (typically) internal hard disk/drives, power supply, cooling fans, and whatever circuit boards plugged into the motherboard, such as a video/graphics card and USB ports.4	Processor
5. 5. Inside is the _____ which is housed on a tiny silicon chip that contains millions of switches and pathways that help your computer interpret and execute instructions. This is where the mathematical calculations and logical comparisons are done.5	CPU
6. 6. Also in the processor is the ______ _______. It is what stores all your data. It houses the hard disk, where all your files and folders are physically located. A typical one is only slightly larger than your hand, yet can hold over 100 GB of data. The data is stored on a stack of disks that are mounted inside a solid encasement.6	Hard Drive
7. 7. Devices used to enter data into the computer; mouse, keyboard, scanner, microphone, digital camera are input devices.7	Input Device
8. 8. Devices used to put out data processed by the computer; monitor, printer, and speaker.8	Output Device
9. 9. A hardware device used to record and store data, such as a hard drive, flash drive, floppy disk, CD ROM, memory card.9	Storage Device
10. 10. A computer’s temporary storage place, where it gets its work done. There are 2 main types.10	Memory
11. 11. It is the main memory and stores data and programs while the computer is running. When the computer is turned off anything in main memory disappears. Computer can read from and write to this memory11	RAM
12. 12. A computer chip that stores specific instructions to manage the computer’s operation. Unlike main memory, this type of memory is non-volatile—the instructions remain permanently on the chip and cannot be changed.12	ROM
13. 13. Bit: short for binary digit, a bit is the smallest memory unit. 8 bits = 1 byte. Byte: short for binary digits eight, 1 byte = 1 character (a letter, number or symbol)Kilobyte: 1,024 bytes, Megabyte: 1,048,576 bytesv Gigabyte: 1,073,741,824 bytes, Terabyte: 1,099,511,627,776 bytes.13	Measuring Memory
14. 14. Loads automatically and controls just about everything on your computer. Example: Microsoft Windows.14	Operating System
15. 15. A two-digit numerical system, which computers use to store data and compute functions. The reason computers use this system is because digital switches inside the computer can only be set to either on or off, which are represented by a 1 or 0.15	Binary
