Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
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”.
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.
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.
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.

Instructions for Submissions thorugh G- Classroom.pptxJheel Barad
This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
3. Coupling
Coupling is measure of the
independence of components.
Coupling is related to cohesion.
It is an indication the strength of inter
connections between the components
in a design .

4. Highly coupled
These types of systems have
interconnections , with program units
dependent on each other.
Jagnesh
Chawla(jagneshchawla@gmail.com)
6. Loosely coupled
Loosely coupled systems are made up
of components which are independent
or almost independent.
In this less dependences are
available.
Jagnesh
Chawla(jagneshchawla@gmail.com)
10. The range of coupling
measures:
Content coupling High coupling
Common
coupling
Loose
Control coupling
Stamp coupling
Data coupling Low
Uncoupled
Jagnesh
Chawla(jagneshchawla@gmail.com)
11. Content coupling:
When one component actually
modifies another .
Then the modified component is
completely dependent on the
modifying one.
Jagnesh
Chawla(jagneshchawla@gmail.com)
13. Common coupling:
We can reduce the amount of coupling
somewhat by organizing our design so
that data are accessible from a
common data store.
Global:
A1
A2
A3
Variables:
V1
V2
Component Component
Component
X Y
Z
Change V1 Increment T T
V =V2+A
To zero V1

14. Control coupling:
When one component passes
parameters to control the activity of
another component.
We say that there is control coupling
between the two.
Jagnesh
Chawla(jagneshchawla@gmail.com)
15. Stamp coupling:
When data structure is used to pass
information from one component to
another.
Jagnesh
Chawla(jagneshchawla@gmail.com)
16. Data coupling:
If only data are passed, the
components are connected by data
coupling.

17. Cohesion:
The cohesion of a component is a
measure of the closeness of the
relationship between its components.
Jagnesh
Chawla(jagneshchawla@gmail.com)
18. Coincidental:
The worst degree of cohesion,
coincidental is found in a component
whose parts are unrelated to one
another.
Jagnesh
Chawla(jagneshchawla@gmail.com)
19. Logical cohesion:
It is the next higher level of cohesion ,
where several logically related functions
or data elements are placed in same
component.
Jagnesh
Chawla(jagneshchawla@gmail.com)
20. Temporal cohesion:
Sometime a component is used to
initialize a system or a set variables.
Such a component performs several
functions in sequence ,but the
functions are related by the timing
involved, so its cohesion is temporal.
Jagnesh
Chawla(jagneshchawla@gmail.com)
21. Procedurally cohesion:
When function are grouped together in a
component just to ensure this order the
component is procedurally cohesive.
Jagnesh
Chawla(jagneshchawla@gmail.com)
22. Communicationally:
Communicationally cohesion often
destroys the modularity and functional
independence of the design.
Jagnesh
Chawla(jagneshchawla@gmail.com)
23. Sequential cohesion:
If the output from one part of a
component is input to the next part the
component has sequential cohesion.
