History of Operating system
Before operating systems, computers were programmed by manually rewiring circuits and loading programs with punch cards or tape. The first operating systems allowed multiple programs to run simultaneously by having a "boss" program control memory and processor time. Early operating systems for personal computers included MS-DOS, which was controlled by typing commands, and later systems introduced graphical user interfaces controlled by a mouse. Major operating systems developed included Windows, Mac OS, Android and iOS.
Operating system
An interface between users and hardware - an environment "architecture”
Allows convenient usage; hides the tedious stuff
Allows efficient usage; parallel activity, avoids wasted cycles
Provides information protection
Gives each user a slice of the resources
Acts as a control program.
Comparison of windows linux and mac os
This presentation compares the Mac OS, Windows OS, and Linux OS. It discusses the key features of each operating system, including security, reliability, ease of use, integration, performance monitoring, files management, and compatibility. It notes that Mac OS is most secure due to only running on Apple devices, while Windows has the most compatibility due to its large market share. Linux is open source and free but may not have complete functionality out of the box. In conclusion, the best operating system depends on the user's needs, such as gaming, programming, or graphics production.
Lesson 2 History Of Operating System
The document summarizes the history of operating systems through four generations:
1) The 1940s saw the earliest computers which had no operating systems and programs were entered manually.
2) In the 1950s, the first operating systems were developed and systems generally ran one job at a time via batch processing.
3) The 1960s introduced multiprogramming which allowed multiple jobs to run simultaneously by switching between them. Techniques like spooling and time-sharing were also developed.
4) The fourth generation saw the rise of personal computers powered by microprocessors, with MS-DOS and UNIX becoming the dominant operating systems.
Lesson 5 Computer Operating System
When a computer turns on, the POST checks that the hardware is functioning properly. It then loads the bootstrap loader from the hard drive. The bootstrap loader loads the operating system into memory and establishes the data structures needed to run it. Finally, it hands over control to the operating system, whose core tasks are processor management, memory management, device management, storage management, and providing interfaces for applications and users.

Computer system organisation
The document summarizes the components and organization of a modern computer system. It consists of a CPU connected through a common bus to various device controllers that provide access to shared memory. Each controller manages a specific device type, like disks or graphics. The CPU and controllers can run in parallel competing for memory access. The initial bootstrap program stored in ROM loads the operating system kernel into memory to start system processes. Hardware and software can trigger interrupts that stop CPU execution and transfer it to a fixed location.
The Boot Process
The document discusses the boot process for various versions of Windows and DOS, including key boot files, boot sequences, alternative boot modes, and troubleshooting startup and shutdown issues. It provides details on CONFIG.SYS and AUTOEXEC.BAT files for DOS, SYSTEM.INI and WIN.INI files for Windows 3.x, and the role of the registry in later Windows versions. Methods for controlling startup programs, creating boot disks and emergency repair disks, and using the recovery console are also outlined.

Introduction, Installation Operating System and Application
The contents of this slide is all about introduction to Operating System (OS) and application, how to install it and some other basic maintenance techniques and tips
Virtual pc
Virtual PC allows multiple operating systems to run simultaneously on a single computer by creating separate virtual machines (VMs). Each VM acts like a fully independent computer with its own processors, memory, storage, and network connections. This enables testing and running incompatible operating systems side by side. Virtual PC provides features like shared clipboard, drag and drop between VMs and the host system. It is useful for rapid testing and reconfiguration by developers, support professionals, and architects. A new product, Microsoft Virtual Server, will provide similar virtualization capabilities for servers.
History of operating systems
An operating system (OS) manages computer hardware and software resources, performing tasks like memory management, process scheduling, and file management. Early computers did not have operating systems, but tools for system management emerged quickly. Major concepts in OS development included supporting an entire product line with a single OS, like IBM's OS/360, and time-sharing, which allowed multiple users to share expensive computers simultaneously. As microcomputers evolved, minimal OSes were developed for early models, while MS-DOS became widely popular through its inclusion with the IBM PC. By the 1990s, more robust OSes with graphical user interfaces became desirable, leading Microsoft and Apple to develop Windows NT and Mac OS X respectively based on Unix.
