Software | Hotel Applications – Hotel Computer Applications
Computer software or simply software is any set of machine-readable instructions that directs a computer’s processor to perform specific operations. Computer software’s contrasts with computer hardware, which is the physical component of computers. Computer hardware and software’s require each other and neither can be realistically used without the other. Using a musical analogy, hardware is like a musical instrument and softwar e is like the notes played on that instrument.

Based on the goal, hotel computer software can be divided into:
1. Application softwar e: which uses the computer system to perform special functions or provide entertainment functions beyond the basic operation of the computer itself. There are many different types of application soft ware, because the range of tasks that can be performed with a modern computer is so large – see list of soft ware’s.
2. System software: which is designed to directly operate the computer hardware, to provide basic functionality needed by users and other soft ware’s, and to provide a platform for running application soft ware’s.
System software’s includes:
Operating systems: which are essential collections of soft ware that manage resources and provides common services for other software’s that runs “on top” of them. Supervisory programs, boot loaders, shells and window systems are core parts of operating systems. In practice, an operating system comes bundled with additional soft ware (including application softw are’s) so that a user can potentially do some work with a computer that only has an operating system.
Device drivers: which operate or control a particular type of device that is attached to a computer. Each device needs at least one corresponding device driver; because a computer typically has at minimum at least one input device and at least one output device, a computer typically needs more than one device driver.
Utilities: which are computer programs designed to assist users in maintenance and care of their computers.
3. Malicious soft ware or malware: which are computer programs developed to harm and disrupt computers. As such, malware is undesirable. Malware is closely associated with computer-related crimes, though some malicious programs may have been designed as practical jokes.
