Why is it necessary for computers to encode information before processing it?
- To translate the information into a format that the computer can understand. (correct)
- To make the information more appealing to users.
- To increase the storage capacity of the computer.
- To protect the information from unauthorized access.

If a computer needs to store both numeric values and textual characters, what encoding principle applies?
If a computer needs to store both numeric values and textual characters, what encoding principle applies?
- Both numeric values and text characters are converted into a binary representation. (correct)
- Text characters are represented as images, while numeric values are directly used.
- Numeric values are stored directly, while text is ignored.
- Only numeric values can be stored; text characters are not supported.

Study Notes
- Computers store different types of information like numeric data, text, images and sound.
- Computers cannot understand this information until it is encoded into a form that they can understand.
- Computers use systems known as number systems to understand information.
Number Systems
- A number system is a numerical system that represents numbers and characters in a computer-readable format.
- Various types of number systems include:
- Decimal (base 10)
- Binary (base 2)
- Octal (base 8)
- Hexadecimal (base 16)
- The binary system consists of 0 and 1.
- The binary system is the fundamental number system.
- The binary system encodes information into a format that a computer can understand.
Storing the Bits
- Information is encoded as patterns of 0s and 1s called bits inside computers and digital machines.
- Bits is short for binary digits.
- Digits 0 and 1 are symbols.
- 0 and 1 have their representation in the binary code.
- A series of these digits can represent characters in an alphabet or punctuation marks.
- Series of digits represent images, numeric values, or sounds.
