For example, an 8-bit unsigned number can represent the values 0 to 255 (11111111). However a two's complement 8-bit number can only represent positive integers from 0 to 127 (01111111), because the rest of the bit combinations with the most significant bit as '1' represent the negative integers −1 to −128.

But, how many numbers can be represented with 2 bits?
A 2-bit system uses combinations of numbers up to two place values (11). There are four options: 00, 01, 10 and 11. A 1-bit image can have 2 colours, a 4-bit image can have 16, an 8-bit image can have 256, and a 16-bit image can have 65,536.
Still and all, how many numbers can a bit Store? two values
For that reason, what is the range of two's complement?
A 4-bit two's complement number also represents 16 values: −8 to 7. In general, the range of an N-bit two's complement number spans [−2N−1, 2N−1 − 1]. It should make sense that there is one more negative number than positive number because there is no −0.
What is the biggest signed integer you can represent using 2's complement with 9 bits?
Since we have one fewer binary digit, the maximum value is 1/2 what it would be for an unsigned number with the same number of bits. The largest positive value in N-bit two's complement is 0111...

The largest number you can represent with 8 bits is 11111111, or 255 in decimal notation. Since 00000000 is the smallest, you can represent 256 things with a byte. (Remember, a bite is just a pattern.
Answer and Explanation: The smallest decimal number that you can represent with three bits is either 0 or -4.
The byte was originally the smallest number of bits that could hold a single character (I assume standard ASCII). We still use ASCII standard, so 8 bits per character is still relevant. This sentence, for instance, is 41 bytes. That's easily countable and practical for our purposes.
For example, 2's complement of “01000” is “11000” (Note that we first find one's complement of 01000 as 10111). If there are all 1's (in one's complement), we add an extra 1 in the string. For example, 2's complement of “000” is “1000” (1's complement of “000” is “111”).
To get the two's complement negative notation of an integer, you write out the number in binary. You then invert the digits, and add one to the result. Suppose we're working with 8 bit quantities (for simplicity's sake) and suppose we want to find how -28 would be expressed in two's complement notation.
The complement of the number 1111 is 8888.
8-bit unsigned numbers There are 256 different unsigned 8-bit numbers. The smallest unsigned 8-bit number is 0 and the largest is 255.
There is no limit to the lowest number a 12-bit binary number can represent in general. With integer encoding, it will often be -(2**11 -1). 1 bit is used to indicate that the value is negative, and 11 bits can represent 2**11 - 1. Although, that's if you define “lowest” to be “most negative”.
To get 1's complement of a binary number, simply invert the given number. For example, 1's complement of binary number 110010 is 001101. To get 2's complement of binary number is 1's complement of given number plus 1 to the least significant bit (LSB).
2 bits, 4 bits, 6 bits, a dollar. In sequence that means they are describing 25 cents, 50 cents, 75 cents, a dollar. Thus a bit is half of 25 cents. The origin of bit comes from the practice of cutting the Spanish dollar (peso) into eight radial pieces to make change.
In computing, a nibble (occasionally nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade. In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet.

A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two's complement, possible values range from −32,768 to 32,767.
The range of values of all 5-bit numbers is: 00001 to 11111 ( that is, 1 to 31). What is the range of numbers that can be represented using 8 bits in 2's complement form?
The largest unsigned integer in 7 bits would be 2^7-1= 127. But signed integer will be 2^6-1=63.
