How many values can we have with 8 bits?

How many values can we have with 8 bits?

256
With 8 bits, the maximum number of values is 256 or 0 through 255. Table 5.1 gives the number of bits in a binary number and the maximum number of states that can be represented. G, gigabits = 1,0737,41,824; K, kilobits = 1024; M, megabits = 1,048,576.

How would you use 8 bits to represent?

8 bits, can represent positive numbers from 0 to 255. hexadecimal. A representation of 4 bits by a single digit 0..

How do you set all bits of a number?

To fill a register with all 1 bits, on most machines the efficient way takes two instructions:

1. Clear the register, using either a special-purpose clear instruction, or load immediate 0, or xor the register with itself.
2. Take the bitwise complement of the register.

What is eight bits associated together called?

From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary.

What is a 8 bit number?

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.

How do you know if a number is divisible by 16 without using an operator?

Note that 10000, 100000,… etc lead to remainder 0 when divided by 16. So remainder of “7*10000 + 6*1000 + 9*100 + 5*10 + 2” divided by 16 is equivalent to remainder of following : 0 + 6*1000 + 9*100 + 5*10 + 2 = 6952 Therefore we can say that the whole number is divisible by 16 if 6952 is divisible by 16.

How do I set my nth bit?

Logic to set nth bit of a number

1. Input number from user. Store it in some variable say num .
2. Input bit position you want to set. Store it in some variable say n .
3. To set a particular bit of number. Left shift 1 n times and perform bitwise OR operation with num . Which is newNum = (1 << n) | num; .

Why do 8 bits make a byte?

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.

What is the highest value of byte?

byte: The byte data type is an 8-bit signed two’s complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive).
