Quick Answer: What Are The Smallest And Largest Numbers That Could Be Represented In 8 Bits?

What’s the smallest decimal number that you can represent with 3 bits?

Answer and Explanation: The smallest decimal number that you can represent with three bits is either 0 or -4..

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…

What are the smallest and largest integers that can be stored as 8 bit 2’s complement numbers?

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.

What’s the largest decimal number that you can represent with 3 bits?

7Answer and Explanation: The largest decimal number that you can represent with 3 bits is 7.

How many numbers can be made with 8 bits?

256There are 28 (256) different possible values for 8 bits. When unsigned, it has possible values ranging from 0 to 255; when signed, it has -128 to 127. Eight-bit CPUs use an 8-bit data bus and can therefore access 8 bits of data in a single machine instruction.

What is the 8 bit two’s complement representation of?

Remember that the scheme two’s complement can represent both positive and negative integers. Since this problem calls for eight bits, put another bit on the left. The eight-bit two’s complement representation of positive 85 is 01010101 .

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 largest number that can be represented using 8 bits?

2558 bits, can represent positive numbers from 0 to 255. hexadecimal. A representation of 4 bits by a single digit 0..

What is the largest unsigned binary number that can be written in 8 bits?

11111111The 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.
