| A Cluster can mean two different things. The first meaning refers to sectors on a disk, the smallest sectors can be identified and accessed on a hard dick but a cluster is a group of these that identifies a file and typically a file will be made up of several clusters. The second meaning refers to groups of computers that are connected, usually by Ethernet and they are often used for processing data (normally scientific). As all the computers are performing the same function (complex scientific calculations or decryption) they are known to be engaging in parallel computing. |
