A block cipher encrypts one byte (or bit) at a time, whereas a stream cipher encrypts an entire block of data at a time is true.

Using a cryptographic key and algorithm, a block cipher encrypts data in blocks to create ciphertext. A stream cipher encrypts data one bit at a time, as opposed to the block cipher, which processes fixed-size blocks simultaneously.

Therefore, note that while stream ciphers change plaintext into ciphertext one byte at a time, block ciphers transform plaintext one block (64/128/256 bits) at a time. Block ciphers become slower as a result since a whole block must be gathered before the data can be encrypted or decrypted.
