Octet (computing) Octet (computing) The octet is a unit of digital information in computing and telecommunications that consists of eight bits. The term is often used when the term byte might be ambiguous, as the byte has historically been used for storage units of a variety of sizes. The term "octad(e)" for eight bits is no longer common. A variable-length sequence of octets, as in Abstract Syntax Notation One (ASN.1), is referred to as an octet string. The international standard IEC 60027-2, chapter 3.8.2, states that a byte is an octet of bits. However, the unit byte has historically been platform-dependent and
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
