Usually, we call a computer with only hardware but no software "bare metal", which cannot do any meaningful work. At present, software can be divided into two categories according to its use: system software and application software. System software is a program designed for computer systems to efficiently use and manage computer software and hardware resources and support the operation of application software. Such as operating systems, programming languages and language processing programs, network system software, system service programs, etc. Among them, Windows operating system is what we often use. Application software is a variety of programs that are user-oriented and written to solve practical problems. It can be written by users themselves or purchased. For example, office XP, Photoshop, Red Alert and so on, which we often use.
