In Parliamentary-Procedure<\/a>, a Quorum<\/a> is necessary for any meeting to be legally valid. According to the source at Britannica<\/a>, the requirement is often specified in an organization's bylaws or constitution. For instance, Roberts-Rules-of-Order<\/a> states that in the absence of a Quorum<\/a>, the only motions that can be entertained are those intended to obtain a Quorum<\/a> or to adjourn the meeting. This prevents legislative bodies from passing laws without sufficient representation.<\/p> In Computer-Science<\/a>, specifically within Distributed-Systems<\/a>, a Quorum<\/a> refers to the subset of nodes that must agree on a state change to maintain Data-Consistency<\/a>. This is a critical component of a Consensus-Algorithm<\/a> such as Paxos<\/a> or Raft<\/a>. These protocols allow systems to achieve Byzantine-Fault-Tolerance<\/a>, ensuring that the network remains operational even if some nodes fail. Technical documentation on this can be found at Distributed Systems and Consensus<\/h2>
