Operating Systems: Components & Representation

An operating system manages hardware resources and provides abstractions that let programs run without controlling every device directly. Operating-system knowledge is essential for programming, performance debugging, concurrency, file handling, security, containers, virtualization, servers, and embedded systems.

An operating system manages hardware resources and provides abstractions that let programs run without controlling every device directly.

supported

The OS multiplexes CPU time through scheduling, isolates address spaces with hardware-supported virtual memory, handles interrupts and exceptions, mediates device access, and persists named data through file systems.

supported

Process tables, system-call traces, file permissions, virtual-memory mappings, scheduler metrics, and device logs expose OS behavior.
