A duplicate of important information, such as a computer program or data, is a backup.
A duplicate copy of a program, a disk, or data, made either for archiving purposes or for safeguarding valuable files from loss should the active copy be damaged or destroyed. A backup is an “insurance” copy. Some application programs automatically make backup copies of data files, maintaining both the current version and the preceding version on disk. Also called: backup copy, backup file.
(Computer science) A copy of a file or directory on a separate storage device; SYN. computer backup.
A system, device, file or facility that can be used as an alternative in case of a malfunction or loss of data.
In computing, a copy file that is transferred to another medium, usually a floppy disc or tape. The purpose of this is to have available a copy of a file that can be restored in case of a fault in the system or the file itself. Backup files are also created by many applications (with the extension .BAC or .BAK); a version is therefore available of the original file before it was modified by the current application. SYN. back-up, back up. + prikaži više

ETYM For fusee, fusil a firelock.
1. Any device by which an explosive charge is ignited; SYN. fuze, fusee, fuzee, primer.
2. Can interrupt the flow of electrical current when it is overloaded; SYN. electrical fuse.
A circuit element that burns out or breaks when the current passing through it exceeds a certain level. A fuse protects a circuit from damage caused by excess current. It performs the same function as a circuit breaker, but it cannot be reset, so it must be replaced if it breaks. A fuse consists of a short length of wire of a specific composition and thickness; the thicker the wire, the more current it can pass before the wire melts and breaks the circuit.
In electricity, a wire or strip of metal designed to melt when excessive current passes through. It is a safety device to stop at that point in the circuit when surges of current would otherwise damage equipment and cause fires. In explosives, a fuse is a cord impregnated with chemicals so that it burns slowly at a predetermined rate. It is used to set off a main explosive charge, sufficient length of fuse being left to allow the person lighting it to get away to safety. + prikaži više
