Encrypting a message consists in changing it to make it incomprehensible to any unintended recipients (who do not have the key to decrypt it).

This is the aim of this lesson as well as the next two lessons on binary code. When they convert the letters into numbers, we will talk about encoding, and when they do the operation in reverse, we will talk about decoding. During this lesson, students will represent a worded message using numbers.

Here, we will use these words according to their scientific definitions:.

The term "coding," for example, is sometimes used to mean "programming" (or "writing code"), "representing data" (for example, binary coding), or "modifying a message to make it incomprehensible" (as in a secret "code"). In common language, the terms "coding," "encoding," and "encrypting" are often misused or used interchangeably.Scientific notes about the vocabulary before starting Encoding of text refers to replacing its letters with corresponding numbers.

A text, which is made up of a series of letters, can be represented by a series of numbers.A letter can be represented by a number.They use this table to encode a message that they send as well as to decode a message they receive. To do this, they make suggestions and then create a correspondence table for the letters and numbers for use by the entire class. Students must encode a textual message using only numbers.
