How does ECB mode encryption function?

Encrypts each block with the same key, where each block is independent of the others

Uses an initialization vector $($IV$)$ to encrypt the first block, then uses the result of the encryption to encrypt the next block

Uses a self$-$synchronizing stream on the blocks, where the initialization vector $($IV$)$ is encrypted and XORed with the data stream

Converts from block to stream, then uses a counter value and a nonce to encrypt the data
