Question

What is the largest value that can be stored in one byte?

a) 8
b) 255
c) 65535
d) 128
e) 16

Answer 1

The largest value that can be stored in a single byte is 255, due to it comprising 8 bits, with 256 different possible combinations. The value 255 corresponds to the binary representation of 11111111.

Step-by-step explanation:

The largest value that can be stored in one byte of computer memory is 255. This is because a byte consists of 8 bits, and each bit can be either a 0 or a 1. There are 28 (or 256) different combinations that can be made with 8 bits, ranging from 00000000 to 11111111. The combination 00000000 is typically used to represent the value 0, therefore the largest value represented is 11111111, which equals 255 in decimal. The correct answer is b) 255.

Regarding the multiplicative prefixes used in computer memory, the unit for one million bytes is referred to as a megabyte (MB).
