A. 256
B. 128
C. 64
D. 512
Check Answer
The correct answer is B) 128.
A 7-bit code can represent 2^7 (2 raised to the power of 7) different bit patterns because there are 2 possible values (0 or 1) for each of the 7 bits. Therefore, the total number of bit patterns provided by a 7-bit code is 2^7 = 128.
