What is Dos Operating System :: MS-Dos Stands for Microsoft Disk Operating System & It is developed by Microsoft Corporation.Dos Operating system was developed in 1981 and its first version was named as Dos 1.00.In Dos work are performed by managing disk And disk files. It Provides a interface between computer hardware and Software programs.
Dos is a 16 bit operating system that means it can save and process 16 bit of data at single time. It is a single user and single tasking Operating system. It is NON-GUI(Graphical User Interface) It Works on CUI(Character User Interface)environment.

Introduction to users and groups in Linux. We will explore how to set user expiry information and force user password change after certain period of time. We will be also providing different permission to users and groups and restricting users and groups operations using sudoers file
It is a Unix like operating system.
It can run on 32 bit and 64 bit hardware.
Linux OS, is a freely distributable, cross-platform
Supports multiple processors.
True multi-tasking, multi-user OS.
Following are some of the important features of Linux Operating System.
Portable - Portability means softwares can works on different types of hardwares in same way.Linux kernel and application programs supports their installation on any kind of hardware platform.
Open Source - Linux source code is freely available and it is community based development project. Multiple teams works in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
Multi-User - Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
Multiprogramming - Linux is a multiprogramming system means multiple applications can run at same time.
Hierarchical File System - Linux provides a standard file structure in which system files/ user files are arranged.
Shell - Linux provides a special interpreter program which can be used to execute commands of the operating system. It can be used to do various types of operations, call application programs etc.
Security - Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.

The presentation on "The MS-DOS File System" will provide a detailed overview of the file system used by Microsoft Disk Operating System (MS-DOS), one of the most popular operating systems of the 1980s and early 1990s.
The MS-DOS file system, also known as FAT (File Allocation Table), was a simple and efficient file system designed for use on floppy disks and hard drives with limited storage capacity. It provided a hierarchical directory structure for organizing files and directories, as well as a method for allocating and managing disk space.
During the presentation, we will discuss the structure and layout of the MS-DOS file system, including the different types of file and directory entries, the file allocation table, and the boot sector. We will also cover how the file system handles file and directory operations, such as creation, deletion, and renaming.
Additionally, we will explore some of the limitations of the MS-DOS file system, such as its maximum file and directory sizes, as well as its lack of support for file permissions and other advanced features found in modern file systems.
A DOS, or disk operating system, is an operating system that runs from a disk drive. The term can also refer to a particular family of disk operating ...
DOS is a family of disk-based operating systems for IBM PC compatible computers. The DOS family primarily consists of Microsoft's MS-DOS and a rebranded ...
In MS-Dos (Disk Operating System) There are two types of Basic dos commands they are internal dos commands and external dos commands which are used separately to perform specific task or operation. Internal dos commands are those commands which are included in command processor (command.com). Internal dos commands are built in command.com file and while the computer has been booted this file or commands are loaded in the computer memory and you can use this basic dos commands while computer is ON.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Disk Operating System
In the late 1980s the operating system that shipped with most PCs was Disk Operating System (DOS)
created by Microsoft: MS-DOS.
MS-DOS is a disk operating system for IBM PC–compatible computers.
In its day, it was the most popular operating system in the world.
It is a Single-user, Single-tasking Computer Operating System that uses a Command Line Interface.
3. Disk Operating System
Despite of its very small size and relative simplicity, It is one of the most successful operating systems
that has been developed to date.
DOS enables the user to organize the files in a disk into directories and sub-directories.
Directory is just like a file folder, which contain all the logically related files.
Directory within another directory is called a sub- directory there may be sub-directories of sub-directories.
4. Structure of MS DOS
The Operating-system loader:
It brings the operating system from the start-up into RAM called Bootstrapping.
The MS-DOS BIOS (Basic Input/Output systems)
Loaded from the file IO.SYS during initialization.
Layer that sits between operating system kernel and hardware.
5. Structure of MS DOS
The MS-DOS Kernel:
Read into memory at initialization time from MSDOS.SYS file on boot disk
Heart of the operating system
it is a proprietary program supplied by Microsoft corporation
The User Interface (shell):
Conventional program that allows the user to interact with the operating system.
Default MS – DOS user interface is a shell program called Command.com
6. Structure of MS DOS
MS-DOS PROMPT:
A command prompt is an entry point for typing computer commands in the Command
Prompt window.
By typing commands at the command prompt, you can perform tasks on your computer
without using the Windows graphical interface.
7. File Organization
DOS files are organized in a hierarchical or an inverted tree-like structure.
Using path to specify the location of files
A path is the route that leads from the root directory of a drive to the file you want to use.
8. File Organization
File naming conventions:
Primary Name and Secondary Name. eg: Letter.doc
Primary name cannot exceed limit of 8 characters.
Extension cannot exceed the limit of 3 characters.
Other Special characters cannot be part of file name. eg: ?, *, >, <,|
There cannot be any spaces in between the file name.
9. File Organization
DOS Files: Files are the basic storage unit for any data or instruction.
Wildcard character will replace a single letter, or word with a wild character ( * , ?)
* Replaces a number of characters
Example: copy a:/*.txt c:/ will copy all text files to drive c:/
? Replaces a single character
Example: copy a:/?????.txt c:/ will copy any 5 letter text file to c:/ ?
10. Commands
Commands are the basic modes through which we can communicate with the computer.
There are two main types of commands which are frequently used by the user in DOS they are:
Internal command
