Ensure security and stability (multi-user, multitasking) for Tech+
Short answer
Ensure security and stability (multi-user, multitasking). An operating system's purpose is to act as intermediary between hardware and user/applications: - Hardware Management: Manages CPU, memory, disks, peripherals. Schedules CPU time, allocates memory, handles I/O operations. - Providing a User Interface: Presents an environment for users (graphical or textual). Hides hardware complexity behind user-friendly abstractions. - Platform for Applications: Provides standard services and APIs that applications use. Allows software compatibility and portability.
