WebAug 28, 2016 · Humans can distinguish over 10 million colors, so 24-bit color is sufficient to represent more colors than humans can distinguish. All modern monitors use this so-called 24-bit color. Some old monitors used 16-bit or 8-bit color, which were relatively impoverished, being only able to represent 65,536 colors (for a 16-bit monitor) or 256 … WebJun 3, 2024 · Tools like OpenPuff can use lossy formats but that then reduces the message capacity.

A byte string can be decoded back into a character string, if you know the encoding that was used to encode it. b'I am a string'.decode ('ASCII') The above code will return the original string 'I am a string'. WebCharacters can have 1 to 6 bytes (some of them may be not required right now). UTF-32 each characters have 4 bytes a characters. UTF-16 uses 16 bits for each character and it represents only part of Unicode characters called BMP (for all practical purposes its enough). Java uses this encoding in its strings.
WebWithout getting into two's complement: 2^8 (since a byte is 8 digits and can have 1 of 2 values) = 256, so the most individual values a byte can represent is 256. so, representing the numbers -128 to -1 is half our range. I believe the question here is why is the max positive value 127 rather than 128. WebBitmap images take up a lot of memory, image compression reduces the amount of memory needed to store an image.
