A computer network (CN) is a group of devices that share resources over a network, with each device represented as a network node. The devices communicate with each other using standard protocols to send or receive data.
Computers on a network can be linked through cables, radio waves, telephone lines, infrared light beams, or satellites. The network can also include other devices that help in communication, known as network devices.
Here are some types of computer networks:
PAN (Personal Area Network): The smallest and simplest type of network
LAN (Local Area Network): The most frequently used network, connecting computers within a limited area, such as a single office or building
MAN (Metropolitan Area Network): A type of network
WAN (Wide Area Network): An enterprise network spanning cities, buildings, and even countries
Wireless networking is about creating and managing wireless connections, commonly used in Wi-Fi. This involves setting up Wi-Fi routers, securing them with passwords, and allowing devices to connect to a network without using physical cables.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
Â
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.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Â
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.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
Â
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.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Â
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.

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).

6. WHAT IS NETWORK ?
• A computer network is a group of computers linked to each other that enables the
computer to communicate with another computer and share their resources, data,
and applications.
A computer network can be categorized by their size.
• A computer network is mainly of Three
types:
a) LAN
b) MAN
c) WAN
www.pskitservices.com
7. LAN
1) Local Area Network is a group of computers connected to each other in a small area such as building,
office , home etc..
2) LAN is used for connecting two or more personal computers through a communication medium such as
twisted pair, coaxial cable, Ofc etc.
3) It is less costly as it is built with inexpensive hardware such as hubs, Switch , network adapters, and
Ethernet cables.
4) The data is transferred at an extremely faster rate in Local Area Network.
5) Local Area Network provides higher security.
www.pskitservices.com
8. MAN
1) A metropolitan area network is a network that covers a larger geographic area by interconnecting a
different LAN to form a larger network.
2) Government agencies use MAN to connect to the citizens and private industries.
In MAN, various LANs are connected to each other through a telephone exchange line.
The most widely used protocols in MAN are RS-232, Frame Relay, ATM, ISDN, OC-3, ADSL, etc.
3) It has a higher range than Local Area Network(LAN).
www.pskitservices.com
9. WAN:-
1) A Wide Area Network is a network that extends over a large geographical area such as city to city ,
states or countries.
2) A Wide Area Network is quite bigger network than the LAN.
3) A Wide Area Network is not limited to a single location, but it spans over a large geographical area
through a telephone line, fibre optic cable or satellite links.
4) The internet is one of the biggest WAN in the world.
5) A Wide Area Network is widely used in the field of Business, government, and education.

10. BASIC REQUIREMENTS TO FORM A
NETWORK :-
1)Two or more computers with Lan card enabled
2) Media (wired or wireless )
3) Networking Devices (HUB, Switch, Router, Modem,
Crimping Tool, Punching Tool, Rack, etc..
4)Logical Address (ip address)
5) Protocols

11. NETWORKING DEVICES:-
Network or Networking Devices are called node they are used to configure ,connect
network
Example :
1) Hub
2) Switch
3) Router
4) Modem
5) Crimping tool
6) Punching tool
7) Cable tester
8) Rack
9) Patch panel
10) Io box
11) NIC Lan-card
www.pskitservices.com
12. NIC/LAN –CARD:-
• NIC is the interface between the computer and the network .
• It is also known as the LAN card or Ethernet card.
• Ethernet cards have a unique 48 bit address called as MAC (Media Access
control address
• Mac address is also called as physical address or hardware address
• The 48 bit MAC address is represented as hexadecimal digits ex. 00-16-
D3-0B-A4-C1
• Network cards available in different speeds
• Ethernet 10 MBPS
• Fast Ethernet 100 MBPS
• Gigabit Ethernet 1000 MBPS
www.pskitservices.com
13. There are two types of NIC:
1)Wired NIC: Cables use the wired NIC to transfer the data over the medium.
RJ45 Jack Lancard
USB RJ45 Jack NIC
www.pskitservices.com
2) Wireless NIC : All the modern laptops use the wireless NIC. In Wireless NIC, a
connection is made using the antenna that employs the radio wave technology.
14. HUB:-
1).Hub is a central device that splits the network connection into multiple devices. When
computer requests for information from a computer, it sends the request to the Hub.
2)Hub distributes this request to all the interconnected computers.
3)It is not an intelligent device.
4) It works with bits, uses broadcast for communications
5) Half duplex communications
www.pskitservices.com
15. SWITCH:-
1) Switch is a networking device that groups all the devices over the network to transfer the
data to another device.
2) A switch is better than Hub as it does not broadcast the message over the network, i.e., it
sends the message to the device for which it belongs to. Therefore, we can say that
switch sends the message directly from source to the destination.
3) Switch called intelligent device also.
4) It support full duplex communications .

• Modem is an intelligent device
• It is used for internet connectivity
• It convert analog signals into digital signals and
digital to analog
• Two types of modems internal and external
18. CRIMPING TOOL:-
A crimping tool is a device used to conjoin two pieces of metal by
deforming one or both of them in a way that causes them to hold
each other. The result of the tool's work is called a crimp. A good
example of crimping is the process of affixing a connector to the end
of a cable.
