A computer network connects multiple devices together through various communication methods to share resources and information. There are several types of networks including LAN, WAN, MAN, and PAN. In a peer-to-peer network, each computer shares its own resources directly with other computers. In a client-server network, servers centralize resources and services that clients can access. Computer networks allow for sharing of hardware, software, data and provide benefits like increased speed, reduced costs, and improved security and collaboration between users.
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. What is a Computer Network?
A system containing any combination of computers, computer terminals,
printers, audio or visual display devices, or telephones interconnected by
telecommunication equipment or cables: used to transmit or receive information.
The Network Diagram
3. Types of Network
There are many types of computer networking which are used world
wide these days. There are some types of network that are using
Worldwide:
LAN - Local Area Network
WAN - Wide Area Network
WLAN - Wireless Local Area Network
PAN - Personal Area Network
SAN - Storage Area Network
GAN - Global Area Network
MAN - Metropolitan Area Network
CAN - Controller Area Network
DAN - Desk Area Network
VPN - Virtual Private Network
8. Peer To Peer Network
In peer to peer network each computer is responsible for making its own
resources available to other computers on the network.
Each computer is responsible for setting up and maintaining its own
security for these resources.
Also each computer is responsible for accessing the required network
resources from peer to peer relationships.
Peer to peer network is useful for a small network containing less than 10
computers on a single LAN .
In peer to peer network each computer can function as both client and
server.
Peer to peer networks do not have a central control system. There are no
servers in peer networks.
Peer networks are amplified into home group.
9. Advantages & Disadvantages of Peer To Peer Network
Advantages:
Use less expensive
computer hardware
Easy to administer
No NOS required
More built in
redundancy
Easy setup & low cost
Disadvantages:
Not very secure
No central point of storage or file
archiving
Additional load on computer
because of resource sharing
Hard to maintain version control
10. Client/Server Network
In client-server network relationships, certain computers act as
server and other act as clients. A server is simply a computer, that
available the network resources and provides service to other
computers when they request it. A client is the computer running a
program that requests the service from a server.
Local area network(LAN) is based on client server network
relationship.
A client-server network is one on which all available network
resources such as files, directories, applications and shared devices,
are centrally managed and hosted and then are accessed by client.
Client serve network are defined by the presence of servers on a
network that provide security and administration of the network.
11. Advantages and Disadvantages of Client/Server Network
Advantages:
• Very secure
• Better performance
• Centralized backup
• very reliable
Disadvantages:
• Requires professional administration
• More hardware intensive
• More software intensive
• Expensive dedicated software
13. File server: These servers provide the services for storing, retrieving
and moving the data. A user can read, write, exchange and manage
the files with the help of file servers.
Printer server: The printer server is used for controlling and
managing printing on the network. It also offers the fax service to
the network users.
Application server: The expensive software and additional
computing power can be shared by the computers in a network with
he help of application servers.
Message server: It is used to co-ordinate the interaction between
users, documents and applications. The data can be used in the for
of audio, video, binary, text or graphics.
Database server: It is a type of application server
14. Applications of Computer Network :
Sharing of resources such as printers
Sharing of expensive software's and database
Communication from one computer to another computer
Exchange of data and information among users via network
Sharing of information over geographically wide areas.
15. Components of Computer Network
Two or more computers
Cables as links between the computers
A network interfacing card(NIC) on each computer
Switches
Software called operating system(OS)
16. Network Benefits
The network provided to the users can be divided into two categories:
Sharing
Connectivity
Sharing Resources
Types of resources are:
Hardware: A network allows users to share many hardware devices
such as printers , modems, fax machines, CD ROM, players, etc.
Software: sharing software resources reduces the cost of software
installation, saves space on hard disk.
17. Other Benefits of Computer Network
Increased speed
Reduced cost
Improved security
Centralized software managements
Electronic mail
Flexible access
Disadvantages of Computer Networks
High cost of installation
Requires time for administration
Failure of server
Cable faults
