This is a brain teaser question, please give a help:
There are 8 bits in a byte. There are 1024 bytes in a kilobyte, 1024
kilobytes in a megabyte, and 1024 megabytes in a gigabyte. A special
message
is 1 megabyte in length, including 128 bytes used for addressing, error
detection, and other overhead. How many bits are in the message?
