Facts about Linux
Cyber security refers to the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access. Cyber security may also be referred to as information technology security.
Also known as stepwise-refinement or decomposition, this approach takes the whole software system as one entity and decomposes it to achieve more than one subsystem based on some characteristics.
When a relation is not in appropriate normal form then the decomposition of a relation is required. It breaks the table into multiple tables. If the relation has no proper decomposition, then it may lead to loss of information. Eliminate some of the problems like anomalies, inconsistencies, and redundancy.
Advanced SQL covers selecting columns, aggregate functions like MIN() and MAX(), the CASE WHEN statement, JOINs, the WHERE clause, GROUP BY, declaring variables, and subqueries

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.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

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.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
4. A computer is a machine which needs only the instructions to
execute it’s tasks.
From the moment it starts booting, it needs instructions.
Without instructions it can’t do anything.
As soon as the computer screen is booted and starts showing
the Windows logo, (with a nice 4 color window), there is
something more going on that cannot meet the eye.
5. Java Virtual Machine
It is the one which is responsible for
doing all the different things which are
displayed on the screen.
6. To understand more clearly, let’s have a look on the
overall structure which is happening
behind the scene
11. This means that when you start an app…
Loads the
app into
memory
Creates
the
processes
Starts the
app
running
12. 1. When app needs memory, it is the kernel that allocates it.
2. When the app wants networking, it is the kernel which does
all the low level processing.
3. When the app wants to perform a task in the background, it
is the kernel which handles the background threads.
4. When the app closes, it is the kernel which cleans up all the
memory and other resources that were used by the app.
15. 1. Monolithic
Kernel
•Where all operating system services operate in kernel space.
•Huge lines of complex code.
•Example: Unix and Linux.
2. Micro
Kernel
•Least approachable.
•More stable with less services in kernel space.
•Has virtual machine and thread scheduling.
•Example: Mach and AmigaOS.
3. Hybrid
Kernel
•Combination of both monolithic and micro kernel.
•Has speed and design of monolithic kernel.
•Has modularity and stability like micro kernel.
•Example: Windows NT and Netware.
4. Exo Kernel
•Follows end-to-end principle.
•Has fewest hardware abstractions.
•Allocates physical resources to applications.
•Example: Nemesis and ExOS.
5. Nano
Kernel
•Provides hardware abstraction without system services.
•Rarely used and thus, it is analogous.
•Example: EROS.
17. Virtual Machine
Kernel Space User Space
Basically,
It is the area in virtual
memory where
kernel processes will run
It is the area in virtual
memory where
user processes will run
18.
19. Some important points…
1. A modern computer operating system usually segregates virtual
memory into kernel space and user space.
2. This separation serves to provide memory protection and hardware
protection from malicious or errant software behaviour.
3. Kernel space is strictly reserved for operating system kernel extensions,
and most device drivers.
4. User space is the memory area where application software and some
related drivers execute.
5. The most common way of implementing user mode instead of kernel
mode involves operating system protection rings
21. Google Finally Begins Their Open-Source Around Linux User-Space Threading
1. Way back in 2013 there was a presentation at the Linux Plumbers
Conference around Google's work on user-level threads and how they
were working on new kernel functionality for using regular threads in
a cooperative fashion and building various features of that.
2. Today, that functionality has been in use internally at Google for a
range of services for latency-sensitive services and greater control
over user-space scheduling while now finally in 2020 they are
working towards open-sourcing that work.
23. 1. Kernel is the central part of the operating system that manages the resources
including memory, processes and various drivers.
2. All multitasking operating systems have a kernel.
3. The rest of the operating system, whether it be Windows, OS X, iOS, or Android, is
built on top of the kernel.
4. Many kernels are also responsible for ensuring that faulty programs do not interfere
with the operation of others by denying access to memory that has not been allocated
to them and restricting the amount of CPU time they can consume.
