Computer number format with a specific number of bits are used to represent varying things and have specific names. A "byte" is a bit string containing the number of bits needed to represent a character. On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. In many computer architectures, the byte is used to address specific areas of memory. For example, even though 64-bit processors may address memory sixty-four bits at a time, they may
Lempel–Ziv–Markov chain algorithm just adds the distance to the front even if already present in the list and SHORTREP and LONGREP[0] don't alter the list. The length is encoded as follows:<br> As in LZ77, the length is not limited by the distance, because copying from the dictionary is defined as if the copy was performed byte by byte, keeping the distance constant. Distances are logically 32-bit and distance 0 points to the most recently added byte in the dictionary. The distance encoding starts with a 6-bit "distance slot", which determines how many further bits are needed. Distances are decoded as a binary concatenation
