Operating Systems for Tech+

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. - File and Data Management: Handles creation, deletion, reading, writing of files. Organizes them into directories/folders.
