Lesson 4: Storing Information

What is the primary function of computers as information processors?

• To create physical objects

• To make information easier for us to use

• To store physical goods

• To replace human labor

Which of the following is an example of input data?

• A printed document

Explain how data is transformed into information.

• By encoding it into binary

• By organizing it to have meaning

• By storing it in a database

• By deleting unnecessary parts

Why is it important to encode data in a format that computers can understand?

• To make it visually appealing

• To ensure compatibility with all devices

• To allow computers to process and interpret the data

• To reduce the size of the data

What is the difference between RGB and Hexadecimal color notations?

• RGB uses letters, while Hexadecimal uses numbers only

• RGB uses three numbers, while Hexadecimal uses six characters

• RGB is used for text, while Hexadecimal is used for images
