Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Encryption is____
A
is used to scramble information so that it can be sent safely without anyone else being able to read it.
B
is the method computers use to make files smaller by reducing the number of bits
C
is data copied to a suitable storage medium then stored safely
D
a high capacity storage device that can be used to backup data or move large amounts of data between machines
Explanation: 

Detailed explanation-1: -Encryption is a process that scrambles readable text so it can only be read by the person who has the secret code, or decryption key. It helps provide data security for sensitive information.

Detailed explanation-2: -For data communicated over a network, modern encryption scrambles data using a secret value or key known only by the recipient and the sender. For stored data, the secret value is typically known only by the data owner. There are different types of encryption and the best systems balance safety and efficiency.

Detailed explanation-3: -Encryption is a way of scrambling data so that only authorized parties can understand the information. In technical terms, it is the process of converting human-readable plaintext to incomprehensible text, also known as ciphertext.

Detailed explanation-4: -This encrypted message is called ciphertext. The two key ingredients needed to send a message to your friend that only they can read is an encryption algorithm and a key. The encryption algorithm is simply a mathematical formula designed to scramble data, while the key is used as part of the formula.
