This document discusses network protocols. It begins with an introduction and history of protocols and defines them as sets of rules that govern communications between devices on a network. Examples of common protocols are then outlined, including TCP/IP, HTTP, FTP, SMTP, UDP, and ICMP. The roles and functions of protocols are explained. Benefits include increased connectivity and transmission speed. The conclusion states that protocols have transformed human communication and networks will continue to evolve.
IP specifies the format of packets, also called #datagrams, and the addressing scheme. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source.

protocol:-A protocol is a set of rules for the exchange of data between a terminal and computer or between two computers. Think of protocol as a sort of recommunication agreement about the form in which a message or data is to be sent and receipt is to be acknowledge.
transmission control protocol(TCP):-This protocol ensures the delivery of information packets across network.
internet protocol (IP):-This important protocol is responsible for providing logical addressing called IP address to route information between networks.
hyper text transfer protocol (HTTP):- This protocol is used to access, send and receive Hypertext Markup Language (HTML) files on the Internet.
simple mail transfer protocol(SMTP):-This protocol is used for transferring email between computers.
file transfer protocol(FTP):-FTP is responsible for allowing file to be copied between devices.
layers:-In computer programming, layering is the organization of programming into separate functional components that interact in some sequential and hierarchical way, with each layer usually having an interface only to the layer above it and the layer below it.

This presentation is about the introduction to network switch layer technology. A network switch is a device tha is used to connect different segments over the network.This ppt includes introduction to switch,types of switches or layer specification,advantages and disadvantages of switch..
I hope it will be very helpful for the engineering students and the others who are interested to search in deep about network switch.
The network layer is responsible for routing packets from the source to destination. The routing algorithm is the piece of software that decides where a packet goes next (e.g., which output line, or which node on a broadcast channel).For connectionless networks, the routing decision is made for each datagram. For connection-oriented networks, the decision is made once, at circuit setup time.
Routing Issues
The routing algorithm must deal with the following issues:
Correctness and simplicity: networks are never taken down; individual parts (e.g., links, routers) may fail, but the whole network should not.
Stability: if a link or router fails, how much time elapses before the remaining routers recognize the topology change? (Some never do..)
Fairness and optimality: an inherently intractable problem. Definition of optimality usually doesn't consider fairness. Do we want to maximize channel usage? Minimize average delay?
When we look at routing in detail, we'll consider both adaptive--those that take current traffic and topology into consideration--and nonadaptive algorithms.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

conclusion
3. computers use network protocols to
communicate in computer networks. There are
many network protocols in existence; TCP/IP
is a family of network protocols that are used
for the Internet.
A network protocol is a standard written
down on a piece of paper (or, more precisely,
with a text editor in a computer). The
standards that are used for the Internet are
called Requests For Comment (RFC).
4. The Internet base protocols and systems were
mainly devised in the 1970s and 1980s.
TCP/IP describes a protocol which will work
on any sort of computer and operating system
for transportation of data across the internet
between different systems
TCP/IP has proven to be remarkably robust,
but is very basic.
5. The word protocol comes from the
Greek protocollon, meaning a leaf of paper glued to
a manuscript volume that describes the contents.
Network Protocol is a set of rules that governs the
communications between computers on a network.
Network protocols are formal standards and
policies comprised of rules, procedures and
formats that define communication between two
or more devices over a network.
Network protocols govern the end-to-end
processes of timely, secure and managed data or
network communication.

How to announce sent data
How to announce receive data
How to address data
How data is to be sent
8. Protocols are needed for predetermined
understandings for communications
It helps the smooth functioning of a
system,such contribution to a system may
benefit or offend you from where you stand
9. TCP : Transmission Control Protocol
HTTP : Hypertext Transfer Protocol
FTP : File Transfer Protocol
SMTP: Simple Mail Transfer Protocol
UDP : User Datagram Protocol
ICMP : Internet Control Message Protocol
SCTP : Stream Control Transmission Protocol
ARP : Address Resolution Protocol
10. TCP/IP:
TCP/IP is a set of rules (protocols) governing
communications among all computers on the Internet.
TCP/IP was developed in 1978 and driven by Bob
Kahn and Vint Cerf.
TCP/IP is a combination of two separate protocols:
Transmission Control Protocol (TCP) and Internet
Protocol (IP).
The Transmission Control Protocol is responsible for
ensuring the reliable transmission of data across
Internet-connected networks.
TCP checks packets for errors and submits requests for
re-transmissions if any are found.
11. HTTP:
The Hypertext Transfer Protocol (HTTP) is
an application protocol for distributed,
collaborative, hypermedia information
systems.HTTP is the foundation of data
communication for the World Wide Web.
Development of HTTP was initiated by Tim
Berners-Lee at CERN in 1989
HTTP is an application layer protocol designed
within the framework of the Internet protocol
suite.
12. FTP:
File Transfer Protocol (FTP) is a standard
Internet protocol for transmitting files between
computers on the Internet
over TCP/IP connections.
FTP is a client-server protocol that relies on two
communications channels between client and
server: a command channel for controlling the
conversation and a data channel for
transmitting file content.
13. SMTP:
Simple Mail Transfer Protocol is used to transport
mail. Simple Mail Transport Protocol is used on
the internet, it is not a transport layer protocol but
is an application layer protocol.
UDP:
- An unreliable connection less protocol used to
control the management of application level
services between computers. It is used for
transport by some applications which must
provide their own reliability.
14. ICMP:
Internet control message protocol provides
management and error reporting to help
manage the process of sending data between
computers. (Management).
ARP:
Address Resolution Protocol enables the
packaging of IP data into ethernet packages. It
is the system and messaging protocol that is
used to find the ethernet (hardware) address
from a specific IP number
15. POP:
POP stands for Post Office Protocol. It is
generally used to support a single client. There
are several versions of POP but the POP 3 is the
current standard.
POP is an application layer internet standard
protocol.
POP does not allow search facility.
It is not suitable for accessing non mail data.
16. Some important benefits are;
They provide the path to increase the network
connections
Enhance the speed of the connection,
Enhance the data transmission rate and
provide easy working to the users
17. Computer Networks and Protocols have
forever changed the way humans will work,
play, and communicate.
New protocols and standards will emerge, new
applications will be conceived, and our lives
will be further changed and enhanced.
