Ans : • It is faster than stream cipher.
• If any block contains any transmission error then it will not have affect on other blocks.
• It is not sufficient in hardware but may be used to connect keyboard to CPU (central process unit)
• Block ciphers can be easier to implement in software, because there is no bit manipulation like in stream cipher which is time consuming process and treats data in computer-sized blocks
• Block Cipher is more suitable in trading applications.
• Short blocks at the end of a message can also be added with blank or zero status.
