software
Software is a collection of computer data and instructions organized in a specific order, which is an intangible part of the computer.
Software is generally divided into system software, application software and middleware between them. Software not only includes all programs running on the computer, but also documents and data related to programs are generally considered as a part of software. Simply put, software is a collection of programs and documents.
Its characteristics are intangible and have no physical form, and its function, characteristics and quality can only be understood through its running state. Software permeates a lot of mental work, and people's logical thinking, intelligent activities and technical level are the keys to software products. Software will not be as old and worn as hardware, but there are defects in maintenance and technical updates.
The development and operation of software must depend on the specific computer system environment and hardware. In order to reduce dependence, the portability and reusability of software are put forward in the development, and the developed software can be easily copied, thus forming multiple copies.
