An operating system manages a computer's hardware resources and provides services for application software. It is found on devices like computers, game consoles, mobile phones, and cars. The main functions of an operating system include managing the processor, memory, storage, devices, and providing a user interface. It ensures each process receives processor time and uses processor cycles efficiently. Memory management involves allocating memory portions to programs and freeing it when unused. Device drivers act as translators between hardware and software. Storage is managed by allocating memory space to processes without overlap and using different memory types effectively.

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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. What is an operating system ? An operating system or OS is a series of programmes what manage the computers hardware resources. Also it provides services for application software. Many devices use operating such as Windows 7, Game consoles and mobile phones such as smart phones.
3. Where might you find an operating system? Operating systems are found everywhere in our day to day lives without us even knowing. We also use them on a day to day basis such as : Computers Game consoles ( Xbox 360, PS3, Nintendo Wii ) Mobile phones SATNAV Cars
4. What are the main functions of an operating system? The main functions of an operating system are to control the main hardware elements in the computer. The five main features of an operating system: Processor management Memory management Device management Storage management User interface
5. Processor management The managing processor comes down to two related issues. Ensuring that each process and application receives enough of the processor's time to function properly. Using as many processor cycles as possible for real work. The processor can only do one thing at a time so the operating system is in charge for sending the task to the processor.
6. Memory management Memory management is the act of managing computer memory. In its simpler forms, this involves providing ways to allocate portions of memory to programs at their request, and freeing it for reuse when no longer needed. The management of main memory is critical to the computer system.
7. Device management The path between the operating system and almost all hardware not on the computer's motherboard goes through a special program called a driver. The drivers job is to be the translator between the electrical signals of the hardware subsystems and the high-level programming languages of the operating system and application programs.
8. Storage management When an operating system manages the computer's memory there are two broad tasks to be accomplished: Each process must have enough memory in which to execute, and it can neither run into the memory space of another process nor be run into by another process. The different types of memory in the system must be used properly so that each process can run most effectively.
9. User interface User interface design is the design of computers, mobile and websites with the focus point on the user's experience and interaction to the interface. The point of user interface design is to make the user's interaction as simple and efficient as possible and something what appeals to the user.
10. What role does the OS play in managing the processor? The OS manage the execution of processes so that you believe lots of things are happening. In order to give the appearance of lots 0f the things happening at the same time the OS has to switch between different processes.
11. What is a device driver? A device driver or software driver is a computer programme which convert the messages from the OS into messages that the hardware device can understand. A device driver simplifies programming by acting as translator between a hardware device and the applications or operating systems that use it.
12. How does a buffer work? A buffer is a region of a physical memory storage used to temporally hold data. The purpose of most buffers is to act as a holding area, enabling the CPU to manipulate data before transferring it to a device. For example, word processors use a buffer to keep track of changes to files. Then when you save the file the word processor updates the disk file with the contents of the buffer.
13. What is a file allocation table? A file allocation table is a table that the operating system uses to locate files on a disk. The name originates from the usage of a table which centralizes the information about which areas belong to files, are free or possibly unusable, and where each file is stored on the disk. To limit the size of the table, disk space is allocated to files in contiguous groups of hardware sectors called clusters.
