1. main goals (Primary goal) is to facilitate the user to be able to use a computer system simple and convenient (for the convenience user.)2. mark the secondary (Secondary goal) is to improve the performance of the system.Sometimes this may conflict with goals 2, such as intelligent systems, OS is running, the system will.Detecting error (Error) at all times. If errors were found during the operation, it will have a notification message (Message) to the user, and if a message often becomes interrupted operation allows the user to work poorly, so the design of the operating system (OS) design and architecture, the machine should be consistent, and to find the mid-point between the structure, the operating system (OPERATING SYSTEM STRUCTURES), the operating system is the software that controls the operation of the hardware, OS, which is a software that works in Low level level command and control machines and devices, and has direct access to the project can be shown hard dawaet the below.
