operating system (OS) Presentation ).pptxFazalAkbar26
Operating System (OS) is a software that manages computer hardware and software resources and provides common services for computer programs. It acts as an interface between the application programs and the machine hardware. The primary objectives of an operating system are to make a computer system easier to use and manage the resources of a computer system. An operating system is an integrated set of programs that control the resources of a computer system and provide its users with an interface or virtual machine that is easier to use than the bare machine .
An operating system is responsible for managing the computer’s memory, processing power, and input/output devices. It also provides a platform for other software to run on top of it. The operating system is responsible for managing the computer’s file system, which includes organizing files, directories, and other data on the computer’s storage devices. It also manages the computer’s network connections, allowing the computer to communicate with other computers and devices on the network .
There are several types of operating systems, including single-user, multi-user, real-time, and embedded operating systems. Single-user operating systems are designed for use by one person at a time, while multi-user operating systems are designed for use by multiple users simultaneously. Real-time operating systems are designed to process data in real-time, while embedded operating systems are designed to run on small, specialized devices such as smartphones, tablets, and other mobile devices .
The most common types of operating systems used today are Microsoft Windows, macOS, and Linux. Microsoft Windows is a popular operating system used on personal computers and laptops. It is known for its user-friendly interface and compatibility with a wide range of software applications. macOS is an operating system developed by Apple Inc. and is used exclusively on Apple’s Macintosh computers. It is known for its sleek design and ease of use. Linux is an open-source operating system that is widely used in servers, supercomputers, and other high-performance computing environments. It is known for its stability, security, and flexibility .
In conclusion, an operating system is a software that manages computer hardware and software resources and provides common services for computer programs. It acts as an interface between the application programs and the machine hardware. The primary objectives of an operating system are to make a computer system easier to use and manage the resources of a computer system. There are several types of operating systems, including single-user, multi-user, real-time, and embedded operating systems. The most common types of operating systems used today are Microsoft Windows, macOS, and Linux.

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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

5. Ubuntu Linux
Linux Mint
Arch Linux
Deepin
Fedora
Debian
Knnopix
Scientific Linux
Chrome OS
openSUSE
The most popular Linux distributions are:
6. • Chrome OS is an operating
system designed by Google that is based
on the Linux Kernel and uses the Google
Chrome web browser as its principal user
interface.
7.
8.
9. Kernel
Kernel is the core part of Linux. It is
responsible for all major activities of this operating
system.
It consists of various modules and it interacts
directly with the underlying hardware.
e.g virtual memory and processes
10. • System Library
System libraries are special functions or
programs using which application programs
or system utilities accesses Kernel's features.
These libraries implement most of the
functionalities of the operating system.
11. • System utilities.
These programs are responsible to do
specialized, individual level tasks.
. Some system utilities may be invoked
just once to initialize and configure some
aspect of the system;
12. • Basic Features of Linux
Portable −
Portability means software can works on
different types of hardware in same way.
Linux kernel and application programs
supports their installation on any kind of
hardware platform.
13. • Open Source
• Linux source code is freely available and it
is community based development project.
Multiple teams work in collaboration to
enhance the capability of Linux operating
system and it is continuously evolving.
14.
15. 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.
16. 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.
17. Linux divides physical memory into three
parts
• ZONE_DMA <16mb
• ZONE_NORMAL >16mb<896mb
• ZONE_HIGHMEM >896mb
18. Each zone has its own allocator, which is responsible for allocating
and freeing all physical pages for the zone and is capable of allocating
in their range. Allocator uses buddy system to
keep track of available pages.
If we need a larger memory it emerges the buddy and in opposite case
it splits
19. • Kernel operations runs in normal zone and
it is the most critical zone. Each Physical
frame is represented by a struct frame.
And all the structs kept in the memory
map array .
20. • Advantages
– Fast and simple compared to general dynamic memory allocation
– Avoid external fragmentation by keeping free physical pages
contiguous
22. • A slab is used for allocating memory for
kernel data
• structures and is made up of one or more
physically contiguous pages.
• A cache consists of one or more slabs.
• There is a single cache for each unique
kernel data structure
23. • For objects smaller than a page
• Implemented on top of page allocator
• Each memory region is called a cache
• Two types of slab allocator
– Fixed-size slab allocator: cache contains objects of same size
• for frequently allocated objects
– General-purpose slab allocator: caches contain objects of size 2^n
• for less frequently allocated objects
• For allocation of object with size k, round to nearest 2^n
24. • Advantages
– Reduce internal fragmentation: many objects in
one page
– Fast: no need to allocate and free page frames
• Allocation: no search of objects with the right size for
fixed-size allocator; simple search for general-purpose
allocator
• Free: no merge with adjacent free blocks
