Operating Systems
- Operating systems manage computer system hardware and software.
- Operating systems act as intermediaries between computer users and computer hardware.
- Four essential subsystem managers are included: Memory Manager, Processor Manager, Device Manager, and File Manager.
- Network Manager assumes responsibility for networking tasks and operating systems with networking capability.
- User Command Interface provides user communication, and users issue commands to the operating system through it.
- Manager tasks involve continuously monitoring resources.
- Policies are enforced to determine who gets what, when, and how much.
Management
- Main Memory Management is in charge of the main memory including Random Access Memory.
- Processor Management is in charge of allocating the Central Processing Unit and tracking process status.
- Device Management is in charge of monitoring all resources.
- File Management is in charge of tracking every file in the system.
- File Management deals with data files, program files, compilers, and application programs.
- Cooperation issues involve an essential manager performing individual tasks.
- Managers interact harmoniously with other managers.
Hardware
- Hardware consists of the physical machine and electronic components.
- Main memory (RAM) handles data/instruction storage and execution.
- Input/Output devices (I/O devices) include all peripheral devices in the system.
- Examples of I/O devices are printers, disk drives, CD/DVD drives, flash memory, and keyboards.
- The Central Processing Unit (CPU) controls the interpretation and execution of instructions
- The CPU controls the operation of the computer system.
Computer Types
- Minicomputers are developed for smaller institutions and are comparable to the mainframe.
- Supercomputers are developed for military operations and weather forecasting.
- Microcomputers are developed for single users in the late 1970s.
- Workstations are the most powerful microcomputers.
- Workstations are developed for commercial, educational, and government enterprises.
Servers and Operating Systems
- Servers provide specialized services.
- Batch Systems rely on input from punched cards or tape.
- Interactive Systems provide faster turnaround than batch systems.
- Real-time systems prioritize reliability and are fast and time-limit sensitive.
- Hybrid systems combine batch and interactive processing.
- Embedded systems are computers placed inside other products.
Threads, Design, and OS Elements
- Threads involve multiple actions being executed simultaneously.
- Object-Oriented Design is a driving force in system architecture improvements.
- The Kernel resides in memory at all times, performs essential tasks, and is protected by hardware.
- Kernel reorganization is memory resident and handles process scheduling and memory allocation.
- The three elements of an OS include the User Interface, Kernel, Multiuser, Multitasking, and Multithreading.
- The User Interface is the part of the OS that you interface with.
- The Kernel is the core of the OS and interacts with the BIOS and the Operating System Types.
- Multiuser systems allow two or more users to work with the computer at the same time.
- Multitasking involves two or more processes running at the same time.
- Multithreading involves two or more parts of the same process running at the same time.
File Systems
- A File is a collection of bytes of information treated as a single unit.
- Windows Registered File Types allow a particular file extension to be registered and associated with a particular program.
