How is the history of operating systems divided in the lecture?

The history of operating systems is divided into four generations: the first generation (1945-1955), second generation (1955-1965), third generation (1965-1980), and fourth generation (1980-1981).

What is MS-DOS, and how did it evolve according to the script?

MS-DOS (Microsoft Disk Operating System) was developed by Microsoft after acquiring 86-DOS from Seattle Computer Products in 1981. It started with 4,000 lines of assembly code and evolved over time to support features like extended memory, batch files, and disk management.

What were the key features of MS-DOS version 1.0?

MS-DOS 1.0 had features such as basic disk management, file handling, and the command processor. It was compatible with CPM and allowed basic file operations and batch scripting.

What was the significance of Windows 1.0 in the evolution of operating systems?

Windows 1.0, released in 1985, was the first graphical user interface operating system by Microsoft, running on top of MS-DOS. It marked the beginning of Windows as an operating system.

How did Windows 95 improve upon previous versions?

Windows 95 introduced the Start Menu, TCP/IP networking support, and enhanced graphical user interface elements, making it a major upgrade from earlier Windows versions.

What was the impact of Windows 10 on the development of operating systems?

Windows 10, released in 2015, was the latest version at the time and introduced improved performance, security, and integration with modern hardware, enhancing user experience significantly.

What is the significance of Android in the context of operating system evolution?

Android, starting with version Alpha in 2008, rapidly evolved into a dominant mobile operating system, with features like battery-saving options, enhanced security, and better multitasking. By version 8.0 Oreo, it had become a highly reliable OS for mobile devices.

What were the features introduced in Android 8.0 Oreo?

Android 8.0 Oreo introduced background limitations to save battery, notification channels, picture-in-picture mode for multitasking, and improved security features.
