The CPU contains a few internal storage locations called ____, each capable of holding a single instruction or data item.

Least Significant Bit

The acronym, LSB stands for

F, It is actually used, and added back into the equation.

The carry (extra bit) in a one's complement calculation is ignored.

D-Wave

The first commercially available quantum computer was built by ____.

15

The hexadecimal number system has 16 symbols, and can count from 0 to _____.

16

The hexadecimal number system uses a base ____.

8

The octal number systems uses the base ____.

F, there are8 bits to every byte.

There are 8 bytes to every bit.

two representations of zero; zero can not be negative

There is one significant problem with the one's complement? Please explain briefly.

F... you divide by the base of the number you are trying to get to.

To complete a decimal to binary conversion, you divide the decimal number by 10.

T

To convert a binary number into the one's complement: invert all the zero's to ones and all the one's to zero's, so that the resulting pattern will give you the original number with the opposite sign.

Quantum
