Question

The differences between encoding and encrypting data are crucial to understand.

Expert Solution
Step 1

Encoding is the process of converting data to another format, such as converting text to binary  or converting an image to a JPEG file. Encoding is a reversible process, meaning that the data can be decoded back to its original form. Encryption, on the other hand, is the process of encrypting data so that no one can read it  without the encryption key. Encryption is an irreversible process, which means that the data cannot be decrypted back to its original form without the encryption key. Encryption is usually used to enhance data  or facilitate transmission, while encryption is used to protect  data from unauthorized access or modification.
