Answer:
The encrypted word for "alphabet" using a Caesar cipher with a shift of 3 would be "dorskdhu".
Step-by-step explanation:
A Caesar cipher is a simple substitution cipher in which each letter in the plaintext is shifted a certain number of places down the alphabet. In this case, the word "alphabet" would be encrypted by shifting each letter 3 places down the alphabet, resulting in the ciphertext "doshdqg".
To illustrate how this encryption works, let's look at the first letter of the word "alphabet", which is "a". With a shift of 3, "a" would be replaced by the letter that is 3 places down the alphabet, which is "d". The second letter, "l", would be replaced by the letter that is 3 places down the alphabet from "l", which is "o". This process is repeated for each letter in the word "alphabet", resulting in the ciphertext "doshdqg".
To decrypt the message, the process is simply reversed by shifting each letter in the ciphertext 3 places up the alphabet.
