Answer:
A Caesar Cipher is a basic encryption type.
Explanation:
Its implementation is very easy and straightforward. It uses a one-to-one of characters in a character set. The input needed is the plain-text message and the encryption number.
For example, using the character set A-Z, encrypting the text CS IS COOL using the key of 3 generates FV LV FRRO. What has been done here is to take each character in the plain-text message and move it by "encryption number steps" in the character set.

Besides being used for transmitting sound and television signals, radio is used for the transmission of data in coded form.
