In general, N bits (binary digits) are required to represent unique integer values. Eight bits are required to represent 256 unique values. Those values range in binary from 00000000 through 11111111, or 0 through 255 in decimal. Looking back at the formula, with N set to 8, is 256.
Each “ x ” character represents a single bit; the right-hand bit is known as the Least Significant Bit (LSB) because it represents the smallest value. Two unsigned binary numbers may be added together using a process identical to that used for decimal addition.
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.
For example, a string of three bits can represent up to eight distinct values as illustrated in Table 1. As the number of bits composing a string increases, the number of possible 0 and 1 combinations increases exponentially.
Using the above formula you’ll see that the smallest four-digit number, 1000, requires 10 bits, and the largest four-digit number, 9999, requires 14 bits. The number of bits varies between those extremes. For example, 1344 requires 11 bits, 2527 requires 12 bits, and 5019 requires 13 bits.
The smallest decimal number that you can represent with three bits is either 0 or – 4.
Explanation: The largest decimal number that we can represent with 3 bits is 7, if binary number system is unsigned that means you can’t represent any negative number in this system. Because all three bits are used in this system. The binary number is 111, which is equal to 7 in decimal.
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.
Remember, the largest unsigned value occurs when all 5 bits are 1’s (11111 = 31) 8. On most computer systems, 8 bits contitutes 1 byte.
In binary (base 2 ), two digits can represent four different values ( 2 ^ 2 ), and in decimal (base 10), two digits can represent 100 different values (10 ^ 2 ). They mean exactly that: Two bits store the values 0, 1, 2, and 3, which have a binary encoding of 00, 01, 10, and 11, respectively.
In computing, bit numbering is the convention used to identify the bit positions in a binary number or a container of such a value. The bit number starts with zero and is incremented by one for each subsequent bit position.
5. Four bits can be used to represent 32 unique things.
With 4 bits, it is possible to create 16 different values. All single-digit hexadecimal numbers can be written with four bits. Binary-coded decimal is a digital encoding method for numbers using decimal notation, with each decimal digit represented by four bits.
By dividing a binary number up into groups of 4 bits, each group or set of 4 digits can now have a possible value of between “0000” (0) and “1111” ( 8+ 4 +2+1 = 15 ) giving a total of 16 different number combinations from 0 to 15.
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. It can represent a letter or a shade of green.)
