HTTP is the application-layer protocol for transmitting hypertext documents across the internet. It works by establishing a TCP connection between an HTTP client, like a web browser, and an HTTP server. The client sends a request to the server using methods like GET or POST. The server responds with a status code and the requested resource. HTTP is stateless, meaning each request is independent and servers do not remember past client interactions. Cookies and caching are techniques used to maintain some state and improve performance.

Embracing GenAI - A Strategic ImperativePeter 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.
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.

2. WHAT IS A PROTOCOL AND HTTP?
• Protocol:
A Protocol is a standard procedure for
defining and regulating communication. For
example TCP, UDP, HTTP etc.
• HTTP is the foundation of data communication for
the World Wide Web.
• The HTTP is the Web’s application-layer protocol
for transferring various forms of data between
server and client like plaintext, hypertext, image,
videos and sounds .
2
3. TERMINOLOGY
•
IP Address: An Internet Protocol address (IP address) is a numerical label assigned to each
device (e.g., computer, printer) participating in a computer network that uses the Internet
Protocol for communication.
•
TCP :Transmission Control Protocol (TCP) is one of the two original core protocols of
the Internet Protocol Suite (IP), and is so common that the entire suite is often called TCP/IP.
TCP provides reliable, ordered, error-checked delivery of a stream of octets between
programs running on computers connected to an intranet or the public Internet.
•
Port Number : A port number is a 16 bit number which when associated with IP address ,
completes the destination address for a communications session.
•
Socket : A socket is nothing but a combination of IP address and port number. It is simply an
end while communication.
3
4. HOW HTTP WORKS?
• HTTP is implemented in two programs: a client
program and a server program, executing on
different end systems, talk to each other by
exchanging HTTP messages.
•
The HTTP client first initiates a TCP
connection with the server. Once the
connection is established, the browser and the
server processes access TCP through their
socket interfaces.
4
10. PERSISTENT AND NON-PERSISTENT CONNECTIONS
• In non-persistent connection each request/response pair are sent over a
separate TCP connection.
• In persistent connections all of the requests and their corresponding responses
are sent over the same TCP connection.
10
11. HTTP REQUEST MESSAGE
•
The first line of an HTTP request message is
called the request line; the subsequent lines are
called the header lines. The request line has
three fields: the method field, the URL field, and
the HTTP version field. The method field can take
on several different values, including GET, POST,
HEAD, PUT, and DELETE etc. The great majority
of HTTP request messages use the GET method.
The GET method is used when the browser
requests an object, with the requested object
identified in the URL field.
11
12. REQUEST METHODS
• GET:
Retrieve Document identified in URL
• HEAD:
Retrieve meta information about document identified in URL
• DELETE:
Delete specified URL
• OPTIONS: Request information about available options
• PUT:
Store document under specified URL
• POST:
Give information to server
• TRACE:
Loopback request message
• CONNECT: For use by Proxies
12
13. HTTP RESPONSE MESSAGES
• It has three sections: an initial status line,
header lines, and then the entity body. The
entity body contains the requested object
itself. The status line has three fields: the
protocol version field, a status code, and a
corresponding status message.
13
14. SOME COMMON STATUS CODES AND
ASSOCIATED PHRASES
• Some common status codes and associated phrases
include:
• 200 OK: Request succeeded and the information is
returned in the response.
• 301 Moved Permanently: Requested object has been
permanently moved; the new URL is specified in Location:
header of the response message. The client software will
automatically retrieve the new URL.
• 400 Bad Request: This is a generic error code indicating
that the request could not be understood by the server.
• 404 Not Found: The requested document does not exist
on this server.
• 505 HTTP Version Not Supported: The requested HTTP
protocol version is not supported by the server.
14
16. HTTP: A STATELESS PROTOCOL
• HTTP is a stateless protocol, because an HTTP server maintains no information
about the clients.
• If a particular client asks for the same object twice in a period of a few
seconds, the server does not respond by saying that it just served the object to
the client; instead, the server resends the object, as it has completely forgotten
what it did earlier.
16
17. USER-SERVER INTERACTIONS: COOKIES
•
HTTP server being stateless, simplifies server design and has permitted engineers to
develop high-performance Web servers that can handle thousands of simultaneous
TCP connections. However, it is often desirable for a Web site to identify users, either
because the server wishes to restrict user access or because it wants to serve content
as a function of the user identity. For these purposes, HTTP uses cookies. Cookies
allow sites to keep track of users.
•
The cookie technology has four components:
•
•
•
•
a cookie header line in the HTTP response message
a cookie header line in the HTTP request message
a cookie file kept on the user’s end system and managed by the user’s browser
a back-end database at the Web site
17
19. WEB CACHING
•
Also called proxy server, is a network entity that
satisfies HTTP requests on the behalf of an origin Web
server.
•
The Web cache has its own disk storage and keeps
copies of recently requested objects in this storage.
•
A Web cache can substantially reduce the response
time for a client request, particularly if the bandwidth
between the client and the origin server is much less
than the bandwidth between the client and the cache.
•
Web caches can substantially reduce traffic
