Which data unit term and value are correctly matched?
A bit = a one or a zero
A bit = eight bytes
A byte = a one or a zero
A byte = eight bits
A gigabyte = one billion bytes
A gigabyte = one million bytes
A megabyte = one million bytes

The solution to this question is given below into the explanation section.

Explanation:

Correctly Matched.

A Bit is equal to one or zero. Bit has  two values either 1 or 0. A byte is equal to eith bits. A gigbyte is equal to one billion (1000000000) bytes.A megabyte is equal to one million (1000000) bytes.

Incorrectly Matched

A bit is not equal to 8 bytes, however 8 bits are equal to 1 byte. A byte is not equal to one or zero because a byte can store upto 8 bit and each bit has two values either 1 or 0;A gigbyte is not equal to one million bytes but its equal to one billion bytes
