Reason why the software system fails 0 Introduction This report will focus on software system failures. In order to understand the cause of the software system failure, it is necessary to understand what the software system is. The software system is an information system. This is because the software system is basically a means of hardware processing information. The definition of Flynn's information system is as follows.

System software is software on a computer designed to control and use computer hardware. There are mainly two types of system software.

1.0 INTRODUCTION An operating system (OS) is a software program that manages computer hardware resources and software resources. The operating system is the basic component of the computer system's system software. An operating system program makes system resources available to users, to the user's application, and to other applications running on the computer. - Wikipedia defines the operating system as a collection of software that manages computer hardware resources and provides public services to computer programs. The most common operating system in the world is Microsoft. On 20th November 1985, Microsoft unveiled Windows. By accounting for over 90% of the global PC market share, Microsoft overcame other operating systems such as the MAC operating system quickly.

One definition of the operating system is "software that manages hardware and software resources and provides services common to applications and users". For example, Windows manages personal computer hardware and supports desktop applications such as web browsers and text processors. iOS manages the hardware of the smartphone and supports mobile applications such as SMS and GPS navigation. These two OS types are typically used by the owner of the device (ie smartphone) or by some friends or family members (ie desktop computers).
