What is your understanding of the difference between a stream cipher and a block cipher?

In a stream cipher, the information is ciphered byte-by-byte.

In a block cipher, the information is ciphered block by block.

Explanation:

Suppose I have the following text:

Buffalo Bills New England Patriots

New York Jets Miami Dolphins

Each line is one byte, so, on the stream cipher, i am going to apply the ciphering algorithm on:

The letter B

The letter u

The letter f

Until

The letter s(of Miami Dolphins)

Now for the block cipher, i am saying that each line is a block, so the algorithm is going to be applied.

First on: Buffalo Bills New England Patriots

Then: New York Jets Miami Dolphins
