Study Notes
Learning Objectives
- Understanding key operating system concepts is crucial.
- Recognizing the categories of operating systems enhances comprehension.
- Identifying the primary roles of an operating system is fundamental.
- Knowledge of the five major components of operating systems is essential.
- Familiarity with current general-purpose operating systems is beneficial.
Introduction to Operating Systems
- Computers execute three primary tasks: Input, Processing, and Output.
- The operating system (OS) controls and coordinates hardware functions.
Features of Operating Systems
- Provides a user interface for interaction.
- Manages storage effectively.
- Oversees process and service management.
- Handles memory and Input/Output management.
- Ensures security and resource protection.
- The kernel is central to the OS operations.
Operating System Categories
- Classified broadly into Single-tasking vs. Multitasking, Single-user vs. Multiuser, and General-purpose vs. Real-time systems.
Single-Tasking vs. Multitasking
- Single-tasking OS can handle one process at a time; common in embedded systems.
- Multitasking OS rapidly switches between processes in memory.
- Cooperative multitasking allows processes to control CPU until termination.
- Preemptive multitasking keeps the OS in control at all times.
Server Operating Systems
- Designed for fault tolerance, allowing recovery from failures.
- Supports clustering to enable multiple servers to function as a single system.
- Load-sharing clusters distribute client requests among servers.
- Hot swapping allows component replacement without system shutdown.
- Scalability facilitated by hot adding components during runtime.
Boot Procedure
- Firmware, stored in non-volatile memory, performs diagnostics and boots the OS.
- BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) initializes booting.
- BIOS performs hardware tests (POST) and loads the OS.
- CMOS memory stores BIOS configuration, accessible via the BIOS setup screen.
Process and Service Management
- A process is a loaded program executed by the CPU.
- Windows Task Manager displays all running processes, including background processes and essential system functions.
Memory and I/O Management
- Memory managed by a dedicated memory manager in kernel mode.
- OS allocates and deallocates memory as processes start and finish.
- I/O management prevents simultaneous access to devices by multiple processes.
