# Why is 255 11111111?

**the step before 256 is all 1's**. Therefore, 255 in binary is 11111111. The step before any power of 2 is a string of 1's.

## Why can't binary go over 255?

If they exceed 255, 2 bytes are used instead of 1. Just like using 2 digits when writing 10 instead of 9.## What does 10101 mean in binary?

The binary number 10101 means 21 in the decimal system.## What does 0100100001101001 mean?

The opening frame of part 3 says, "0100100001101001" which is binary for "hi" in ascii.## What is 10011101 in binary code?

157 in binary is 10011101. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 8 bits to represent 157 in binary.## BINARY NUMBER SYSTEM with one button: 0-255 / 00000000-11111111 - (Digital Logic Sim)

## Why is 8-bit 256?

Since computers work with binary numbers, all powers of two are important. 8bit numbers are able to represent 256 (2^8) distinct values, enough for all characters of English and quite a few extra ones. That made the numbers 8 and 256 quite important.## Why is 8 bits 255 and not 256?

A byte has only 8 bits. A bit is a binary digit. So a byte can hold 2 (binary) ^ 8 numbers ranging from 0 to 2^8-1 = 255. It's the same as asking why a 3 digit decimal number can represent values 0 through 999, which is answered in the same manner (10^3 - 1).## What happens if you add 00000001 to 11111111 in binary?

Answer. 1+1=0 and 1 will be carried to the next column . sol.## What is binary code 1111111?

127 in binary is 1111111. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits).## What is 8 bits 11111111 called?

A collection of eight bits is called Byte. Somebody made a joke about a group carrying a byte of the data, and the term stuck. Sometimes you hear a group of four bits called a nibble. The largest number you can represent with 8 bits is 11111111, or 255 in decimal notation.## What is 192.168 1.1 in binary?

An IP address is a 32 bit number like 11000000101010000000000100000001 in binary or 3232235777 in decimal. So it is written in 4 parts like 11000000.10101000. 00000001.00000001 in binary form and 192.168. 1.1 in decimal form.## Why is 11 in binary code three?

3 in binary is 11. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 2 bits to represent 3 in binary.## Is 1 byte 255 or 256?

A byte is not just 8 values between 0 and 1, but 256 (2^{8}) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111 . Thus, one byte can represent a decimal number between 0(00) and 255.
