💡 Core Concepts & Definitions

▼

Click on each flashcard to reveal the definition:

Operating System
An intermediary between user and hardware that acts as both a resource manager and an extended machine, providing abstraction and simplifying hardware complexity.[1]
Kernel
The core part of the operating system that runs continuously, managing all other programs and providing essential services.[1]
Multiprogramming
Keeping multiple programs in memory simultaneously to maximize CPU utilization by overlapping CPU and I/O operations.[1]
Time-Sharing
A system that provides interactive experience to multiple users by rapidly switching CPU among jobs using time slices (quantum).[1]
Real-Time OS
An operating system designed to meet strict timing constraints and deadlines, classified as Hard RTOS or Soft RTOS.[1]
Monolithic Kernel
All OS services run in a single kernel space with high performance but low reliability - one fault can crash the entire system.[1]
