Study Notes
Understanding System Software Operating Systems
- An operating system (OS) is a group of programs that manages computer functions and consists of the OS and utility programs for system maintenance.
- The OS manages computer hardware, coordinates applications and CPU, and schedules tasks.
- Operating systems are categorized by the devices they are installed in, such as robots, mainframes, network computers, mobile devices, and personal computers.
- Real-Time Operating Systems (RTOS) are designed for machinery performing repetitive tasks and require minimum user interaction, used in devices like TV cameras, cars, and medical equipment.
- Mainframes and network operating systems manage multiple users and multitasking, examples include Windows Server, Linux, and Unix.
- The top three operating systems for personal computers are Windows, Mac OS X, and Linux (open source), with Windows 8 optimized for touch screens and cloud-based OS.
- The dominant operating system for mobile devices is Android, allowing multitasking.
- The OS coordinates and directs the flow of data and information.
- The user interface enables user-computer interaction through command-driven, menu-driven, and graphical interfaces.
- Processor management performs multiple tasks at once, arranges task execution, and handles events like keystrokes and mouse clicks.
- Preemptive multitasking prioritizes high-priority tasks such as printing.
- Virtual memory is used when RAM is full, storing unused instructions on the hard drive, and increasing RAM can reduce the use of virtual memory.
