Operating Systems
Definition Helps computers run smoothly Allows multiple tasks at once User-friendly interaction
- Main Job of OS Acts as a middleman between user and hardware Manages resources
- Historical Context Early Computers: Single-task systems Key Games: Pong: One of the first digital computer games Pac-Man: Iconic game from 1980
- Security Role of OS Controls access to files Keeps files secure
- User Interfaces Graphical User Interface (GUI) Icons and visual elements for easy navigation Start Menu: Quick access to programs Desktop: Main screen area with icons Task Execution: Uses buttons and images to control apps
- Command-Line Interface (CLI) Text-based commands Preferred by advanced users
- Multitasking Modern OS feature allowing multiple apps simultaneously
- Types of OS Linux Open-source, popular in security fields
- Mobile Operating Systems Example: Android on phones and tablets
- Programming Concepts in OS Function: Reusable code block Variable: Data storage, e.g., a game score Sprite Properties: Object features like visibility Creating a Sprite: Uses commands like createSprite()
- Security Analyst Protects computers through firewalls and security measures
- Hardware Physical components (CPU, memory) Managed by OS
- Binary Language Computer’s language (0s and 1s) OS translates commands into binary
