Overview of HTTP, HTML, WWW and web technologies.
The combo HTTP and HTML is the foundation of the World Wide Web (WWW).
HTML (HyperText Markup Language) defines a text-based format for describing the contents of a web page. HTML is based on tags similar to XML (eXtensible Markup Language), but its definition is less strict.
HTML pages are transported with the HTTP protocol (HyperText Transmission Protocol) over TCP/IP based networks.
The power of the WWW comes with the links based on URLs (Uniform Resource Locators) that connect pages to form a web of content.
Browsers display links as clickable items that, when clicked, trigger the browser to load the web page pointed to by the link.
This statelessness contributed a lot to the stability and scalability of the world wide web where web servers are only tasked with the delivery of web pages while the browser is responsible for the rendering of web pages.
The static nature of the early World Wide Web was soon augmented with the dynamic creation of web pages by web servers or by enriching static web pages with dynamic content.
Technologies like CGI (Common Gateway Interface), JSP (Java Server Pages) or ASP (Active Server Pages) were developed to provide the infrastructure to build dynamic web applications.
These server-side technologies were complemented with client-side technologies like Javascript and AJAX (Asynchronous Javascript And XML).
Web page caching is an important mechanism to reduce latency in loading web pages and reducing network traffic.
HTTP defines different caching control mechanisms. Simpler caching methods are based on web page expiry dates while more complex mechanisms use web page validation.
This ppt will give you information about what is http protocol, who had developed it, how it works, http request and response, features, advantages, disadvantages and brief information about world wide web.

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 Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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.

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.
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”.

2. Servlet Terminology Description
Website It is a collection of related web pages that may contain text, images,
audio and video.
HTTP It is the data communication protocol used to establish communication
between client and server.
HTTP Requests It is the request send by the computer to a web server that contains all
sorts of potentially interesting information.
Get & Post Get form data is visible in URL and Post form is Hidden in URL
Container It is used in java for dynamically generating the web pages on the
server side.
Server It is used to manage the network resources and for running the
program or software that provides services.
Content Type It is HTTP header that provides the description about what are you
sending to the browser.
3. 1. Static vs Dynamic website
Static Website Dynamic Website
Content is same every time the page is loaded. Content is generated quickly and changes
regularly.
It uses the HTML code for developing a
website.
It uses the server side languages such
as PHP,SERVLET, JSP, and ASP.NET etc. for
developing a website.
It sends exactly the same response for every
request.
It may generate different HTML for each of the
request.
The content is only changed when someone
publishes and updates the file (sends it to the
web server).
The page contains "server-side" code which
allows the server to generate the unique
content when the page is loaded.
Flexibility is the main advantage of static
website.
Content Management System (CMS) is the
main advantage of dynamic website.
4. 2. HTTP (Hyper Text Transfer Protocol)
1. The Hypertext Transfer Protocol (HTTP) is application-level protocol
for collaborative, distributed, hypermedia information systems. It is
the data communication protocol used to establish communication
between client and server.
2. HTTP is TCP/IP based communication protocol, which is used to
deliver the data like image files, query results, HTML files etc on the
World Wide Web (WWW) with the default port is TCP 80. It provides
the standardized way for computers to communicate with each other.
5. The Basic Characteristics of HTTP (Hyper Text Transfer Protocol):
1. It is the protocol that allows web servers and browsers to exchange
data over the web.
2. It is a request response protocol.
3. It uses the reliable TCP connections by default on TCP port 80.
4. It is stateless means each request is considered as the new request.
In other words, server doesn't recognize the user by default.
6. Features
1. HTTP is media independent: It specifies that any type
of media content can be sent by HTTP as long as
both the server and the client can handle the data
content.
2. HTTP is connectionless: It is a connectionless
approach in which HTTP client i.e., a browser initiates
the HTTP request and after the request is sent the
client disconnects from server and waits for the
response.
3. HTTP is stateless: The client and server are aware of
each other during a current request only. Afterwards,
both of them forget each other. Due to the stateless
nature of protocol, neither the client nor the server
can retain the information about different request
across the web pages.
7. HTTP Requests
1. The request sent by the computer to a web server, contains all sorts
of potentially interesting information; it is known as HTTP requests.
2. The HTTP client sends the request to the server in the form of
request message which includes following information:
a. The Request-line (URL)
b. The analysis of source IP address, proxy and port
c. The analysis of destination IP address, protocol, port and host
d. The Requested URI (Uniform Resource Identifier)
e. The Request method and Content
f. The User-Agent header
g. The Connection control header
h. The Cache control header
8. GET VS POST
GET POST
In case of Get request, only limited amount of
data can be sent because data is sent in
header.
In case of post request, large amount of
data can be sent because data is sent in body.
Get request is not secured because data is
exposed in URL bar.
Post request is secured because data is not
exposed in URL bar.
Get request can be bookmarked. Post request cannot be bookmarked.
Get request is idempotent . It means second
request will be ignored until response of first
request is delivered
Post request is non-idempotent.
Get request is more efficient and used more
than Post.
Post request is less efficient and used less
than get.
9. Container
1. It provides the runtime environment for applications. The client/user
can request only a static WebPages from the server. If the user
wants to read the web pages as per input then the container is used
to handle it.
2. The container is the part of web server which can be run in a
separate process.
3. Standalone: It is typical servers in which the container and the web
servers are the integral part of a single program.
For example:- Tomcat running by itself
10. b. In-process: It is separated from the web server, because a different
program runs within the address space of the main server as a
plug-in. For example:- Tomcat running inside the JBoss.
c. Out-of-process: The web server and container are different
programs which are run in a different process. For performing the
communications between them, web server uses the plug-in
provided by the servlet container.
11. Server: Web vs. Application
1. Server is a device or a computer program that accepts and
responds to the request made by other program, known as client. It
is used to manage the network resources and for running the
program or software that provides services.
2. There are two types of servers:
a. Web Server
b. Application Server
12. BASIS FOR COMPARISON WEB SERVER
APPLICATION SERVER
Basic Web servers are suitable for static
content.
Application servers are suitable for
dynamic content.
Features Involve only web or servlet container
and cannot be used for EJB.
Could contain a web server and
also contain web and EJB
containers.
Assists scripting languages through
plugins such as PHP, ASP, JSP etc.
Assists application services object
pooling, transaction support etc.
Multithreading Not supported Supports multithreading
Uses HTML and HTTP Graphical user interface, HTTP,
RPC/RMI.
Resource Utilization Low High
Provides environment to run Web application Enterprise application
13. Content Type
List of Content Types
The commonly used content types are
given below:
text/html
text/plain
application/sword
application/vnd.ms-excel
application/jar
application/puff
application/octet-stream
application/x-zip
images/jpeg
