Hexadecimal codes

c

Decimal numbers only

2

What does a barcode or QR code pattern represent in data terms?

a

A type of sound wave

b

A visual art style

c

Encoded information that can be read by scanners

3

What is the basic unit that computers use to store and process data?

a

Binary digits (bits)

b

Pixels

c

Bytes

4

Which concept describes how a digital image is built from tiny squares called pixels?

a

Vectors

b

Scalar colors only

c

Each pixel stores a binary value for position and colour

5

How is sound typically stored in digital form?

a

As continuous analogue values only

b

As color codes

c

As binary samples taken many times per second

6

What happens when data size increases or decreases in digital storage?

a

Only size increases

b

Quality and size may change due to compression and precision

c

Only quality increases

7

Which best explains how a QR code encodes information for quick access?

a

Patterns of data patterns scanned to retrieve stored data

b

Random colors to confuse scanners

c

Manual decoding by humans only

8

In digital imagery, what does each pixel's binary value determine?

a

The image file name

b

Its colour and position on the image

c

The number of edges in the image

9

Why are 0s and 1s sufficient to represent diverse data types?

a

They are the only digits available

b

They can encode numbers, text, images, and sounds

c

They can only represent on/off states

10

What is a key feature of a stored digital sound?

a

Thousands of samples per second stored as binary data

b

A single value per second

c

Only the bit rate matters, not sampling

11

Which statement is true about how binary data is stored?

a

Binary data never changes after storing

b

All data is stored with perfect quality

c

Data size and quality depend on storage method and compression

12

What is the relationship between pixels and binary in images?

a

Binary only encodes brightness, not color

b

Pixels are independent of binary

c

Each pixel has a binary value for colour and position

13

How can you test understanding of barcodes and QR codes?

a

Interpret simple codes to access information

b

Ignore pattern recognition

c

Create musical compositions from codes

14

Which statement best describes data representation in binary?

a

Binary is used to represent numbers, letters, and images

b

Binary cannot encode text

c

Binary is only for hardware wiring
