Final answer:
The valid byte from the given options is 00000000, as it contains exactly 8 binary digits and only includes the numbers 0 and 1.
Step-by-step explanation:
The valid byte from the options provided is 00000000. A byte consists of 8 bits, and each bit can be either a 0 or a 1. Here's a breakdown of the options:
- 11100 - This is only 5 bits long, so it is not a valid byte.
- 11011011 - This is a valid byte because it has 8 bits.
- 00000000 - This is also a valid byte; all bits are 0, but there are 8 of them, making it a byte.
- 10022011 - This is not a valid byte because it contains numbers other than 0 and 1.
Therefore, the only valid byte in the list is 00000000 because it contains exactly 8 binary digits.
