Applied Cryptography Pretend that one byte of a cipher text gets

Pretend that one byte of a cipher text gets garbled, either through accident or malicious action. What is the impact of this one byte of garbled data on the decryption for CBC, OFB, and CTR modes? What is the impact of a dropped block on CBC, OFB, and CTR modes? Say CBC mode encryption is used to encrypt a 1024 bit message with a block cipher having a 256 bit key, a 128 bit block length. What is the length of the resulting cipher text? Why? Pretend that one byte of a cipher text gets garbled, either through accident or malicious action.
