very helpful presentation for students who are dealing with network and operating system have a brief introduction about linux and installation of ubuntu and windows Server.I hope you like it.
Introduction to OS, Operating system functions, evaluation of O.S., Different types of O.S.,
Batch multi programmed, Time-sharing, Real-time, Distributed, Parallel.
Computer hardware is useless without software.
Software is the set of instructions and associated data that direct the computer to do a task.
Software can be divided into two categories:
System software and application software.
System software helps the computer to carry out its basic operating tasks.
Application software helps the user carry out a variety of tasks.

Embracing GenAI - A Strategic ImperativePeter 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. 2
What is an Operating System (1)?
• A modern computer consists of:
One or more processors
Main memory
Disks
Printers
Various input/output devices.
• Managing all these varied components
requires a layer of software – the
Operating System (OS).
3. 3
What is an Operating System (2)?
• An Operating System is a program that acts as
an intermediary/interface between a user of a
computer and the computer hardware.
• OS goals:
– Control/execute user/application programs.
– Make the computer system convenient to use.
– Ease the solving of user problems.
– Use the computer hardware in an efficient manner.
5. 5
Function of an OS
• Facilities for program creation
– editors, compilers, linkers, debuggers, etc.
• Program execution
– loading in memory, I/O and file initialization.
• Access to I/O and files
– deals with the specifics of I/O and file formats.
• System access
– resolves conflicts for resource contention.
– protection in access to resources and data.
6. 6
Why are Operating Systems Important?
• Important to understand and know how to correctly
use when writing user applications.
• Large and complex systems that have a high
economic impact and result in interesting problems
of management.
• Few actually involved in OS design and
implementation but nevertheless many general
techniques to be learned and applied.
• Combines concepts from many other areas of
Computer Science: Architecture, Languages,
Data Structures, Algorithms, etc.
8. 8
Views of an Operating System
• There are three classical views (in literature):
1. Resource Manager – manages and allocates
resources.
2. Control program – controls the execution of user
programs and operations of I/O devices.
3. Command Executer – Provides an environment
for running user commands.
• But one more modern view: the Operating
System as a Virtual Machine.
9. 9
1. Resource Manager
• Resource Manager:
– Manages and protects multiple computer resources: CPU,
Processes, Internal/External memory, Tasks, Applications,
Users, Communication channels, etc…
– Handles and allocates resources to multiple users or
multiple programs running at the same time and space
(e.g., processor time, memory, I/O devices).
– Decides between conflicting requests for efficient and fair
resource use (e.g., maximize throughput, minimize
response time).
• Sort of a bottom-up view.
11. 11
2. Control Program
• Control Program:
– Manages all the components of a complex
computer system in an integrated manner.
– Controls the execution of user programs and
I/O devices to prevent errors and improper
use of computer resources.
– Looks over and protects the computer:
Monitor, Supervisor, Executive, Controller,
Master, Coordinator ….
• Sort of a black box view.
12. 12
3. Command Executer
• Command Executer:
– Interfaces between the users and machine.
– Supplies services/utilities to users.
– Provides the users with a convenient CLI
(Command Language Interface), also called
a Shell (in UNIX), for entering the user
commands.
• Sort of a top-down view.
