Study Notes

Overview of Operating Systems

An operating system (OS) is software that serves as an interface between users and computer hardware.
Functions as a resource manager, handling critical tasks effectively and efficiently.
Responsibilities include file management, memory management, process management, and I/O management.

Generations of Operating Systems

First Generation (1940 to early 1950s)
- No OS in early computers; users controlled devices directly in machine language.
- Programs executed basic calculations without the need for an OS.
Second Generation (1955 - 1965)
- GMOSIS, the first OS, developed for IBM computers.
- Introduced batch processing, where jobs grouped and executed collectively using punch cards.
Third Generation (1965 - 1980)
- Emergence of multiprogramming, allowing simultaneous task execution.
- Mainframes became prevalent, enhancing operating system capabilities.
- DEC PDP-1 launched in 1961, fostering significant development in computing.
Fourth Generation (1980 - Present Day)
- Personal computers rose due to advancements from the previous generation.
- Microsoft released early versions of Windows (1975) and MS-DOS (1981), ultimately leading to widely adopted OS like Windows 10.
- Other renowned OS include Apple's macOS.

Evolution of Operating Systems

No OS (0s to 1940s)
- Manual instruction typing for tasks was cumbersome and time-consuming.
- Lack of a user-friendly interface limited accessibility for non-experts.
Batch Processing Systems (1940s to 1950s)
- Introduction of punch cards for job submissions, leading to batch job execution.
- CPU handled jobs sequentially from batches for efficiency.
Multiprogramming Systems (1950s to 1960s)
- Allowed multiple program loading into memory, enhancing CPU utilization.
- Enabled job switching when one program required I/O operation.
Time-Sharing Systems (1960s to 1970s)
- Extended multiprogramming by allocating CPU time in intervals.
- Allowed multiple users to access CPU with equitable time distribution.
Introduction of GUI (1970s to 1980s)
- Graphical User Interfaces made OS more user-friendly.
- Users interacted with visual elements rather than typing commands.
Networked Systems (1980s to 1990s)
- Designed to manage computer network communication.
- OS like Novell NetWare and Windows NT facilitated collaborative environments and file sharing.
Mobile Operating Systems (Late 1990s to Early 2000s)
- Development of OS for smartphones, optimizing devices for mobile usage.
- Notable examples include iOS and Android.
AI Integration (2010s to ongoing)
- Artificial intelligence features integrated for enhanced user interaction (e.g., voice commands).
- Technologies like Siri and Google Assistant represent AI advancement in OS capabilities.
