The document summarizes the basic components and functions of a computer system. It discusses how a computer accepts data through input devices, stores and processes the data, and provides results through output devices. The key components are the central processing unit (CPU), memory, hardware, and software. The CPU contains a control unit and arithmetic logic unit to control operations and perform calculations. Hardware refers to the physical and visible parts, while software programs tell the computer what to do. Together, these components work to process data and provide useful information to the user.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
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.

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.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
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.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
2. A Computer is a
programmable
electronic machine
that performs high-
speed mathematical
or logical operations,
stores & processes
data to get meaningful
information.
Definition of Computer
7. System Unit - the metal box that houses
the processor, main memory, and
secondary storage devices.
– Abbreviated to “CPU”
Input and output devices - attached to
the system unit via a device controller.
– The terms "input" and "output" tell you if
data flow is into or out of the system unit.
– Abbreviated to “I/O”
Parts of a Computer System
8. Basic Operations of Computer
It accepts data or instructions by any
way of input.
It stores data.
It can process data as required by the
user.
It controls all operations inside a
computer.
It gives results in the form of output
10. The Components Inside

23. The CPU
The CPU is Central Processing Unit
i.e. “Heart” of Computer System.
It is a silicon chip that contains
millions of tiny electrical
components.
The CPU’s three main parts are:
– Control Unit
– Arithmetic Logic Unit (ALU)
– Registers
24. Arithmetic / Logic Unit
Registers
Control Unit

25. The CPU controls all of the other resources within the
system, in order to accomplish a task.
Component Interaction
26. Any type of device that provides
data from a computer to the
outside world
Examples of output data:
– A printed report
– An image such as a picture
– A sound
Common output devices include:
– Monitor (display screen)
– Printer
Output Devices
28. User hits

Y = X+2
OUTPUT Y
The performance of the CPU is dependent on both its speed and
memory
Working of the CPU
29. Access to Instructions
The hard disk is too slow to provide instructions to
the CPU. So programs are first loaded into main
memory, which is much faster. The CPU can then
access the instructions more quickly.
30. Cache Memory
But as CPU speeds became faster,
the main memory couldn’t provide
the CPU with the instructions at a
fast enough rate.
So even faster memory ( cache
memory) is now placed between the
CPU and main memory to provide
the instructions at quicker rate to the
CPU.
31. Cache Memory
When an instruction or data is accessed from main
memory, it is placed in the cache. Second and
subsequent use of the same instruction/data will
then be faster, since it is accessed directly from the
cache.
