Networks connect two or more computers using various mediums like cables or wireless signals. They allow for sharing of files, data, and applications between systems without needing to physically transfer anything. Networks can be configured in a client-server model where some computers act as servers providing resources and other computers act as clients accessing those resources. Alternatively, networks can use a peer-to-peer model where each computer both acts as a client and server, allowing all systems to share directly. Networks can operate within a single location or span multiple geographic areas. Hardware like network interface cards and cables form the physical infrastructure while networking software manages communication and resource sharing.
A computer network connects multiple computers together to share resources and information. There are several types of computer networks including local area networks (LANs) which connect computers in a small physical area like a home or office, wide area networks (WANs) which connect LANs across cities and countries, and metropolitan area networks (MANs) which connect networks across a larger region like a city. Common network topologies include star, ring, bus, and tree networks which determine how the connected computers communicate with each other.
1) A computer network connects computers together to share resources like printers, files, and internet connections. Networks can be local-area networks within a building or wide-area networks spanning cities.
2) Common network topologies include star, bus, ring, tree and mesh. Star networks connect devices to a central hub while bus networks use a common backbone cable. Ring networks transmit messages in one direction around a closed loop.
3) Computer networks allow for resource sharing, improved communication and availability of information, though they also present security risks and require maintenance of hardware and software.

Challenge #1. Ensuring Test Environment Consistency: Establishing a standardized test execution environment across hundreds of Azure DevOps agents is crucial for achieving dependable testing results. This uniformity must seamlessly span from Build pipelines to various stages of the Release pipeline.
Challenge #2. Coordinated Test Execution Across Environments: Executing distinct subsets of tests using the same automation framework across diverse environments, such as the build pipeline and specific stages of the Release Pipeline, demands flexible and cohesive approaches.
Challenge #3. Testing on Linux-based Azure DevOps Agents: Conducting tests, particularly for web and native apps, on Azure DevOps Linux agents lacking browser or device connectivity presents specific challenges in attaining thorough testing coverage.
This session delves into how these challenges were addressed through:
1. Automate the setup of essential dependencies to ensure a consistent testing environment.
2. Create standardized templates for executing API tests, API workflow tests, and end-to-end tests in the Build pipeline, streamlining the testing process.
3. Implement task groups in Release pipeline stages to facilitate the execution of tests, ensuring consistency and efficiency across deployment phases.
4. Deploy browsers within Docker containers for web application testing, enhancing portability and scalability of testing environments.
5. Leverage diverse device farms dedicated to Android, iOS, and browser testing to cover a wide range of platforms and devices.
6. Integrate AI technology, such as Applitools Visual AI and Ultrafast Grid, to automate test execution and validation, improving accuracy and efficiency.
7. Utilize AI/ML-powered central test automation reporting server through platforms like reportportal.io, providing consolidated and real-time insights into test performance and issues.
These solutions not only facilitate comprehensive testing across platforms but also promote the principles of shift-left testing, enabling early feedback, implementing quality gates, and ensuring repeatability. By adopting these techniques, teams can effectively automate and execute tests, accelerating software delivery while upholding high-quality standards across Android, iOS, and web applications.

8. NEED OF COMPUTER NETWORK
1. File sharing
Networking of computers helps
the network users to share data files.
9. 2. Hardware sharing
Users can share devices such as printers,
scanners, CD-ROM drives, hard drives etc .
Without computer networks, device sharing
is not possible.
11. 4. User communication
Networks allow users to communicate
using e-mail, newsgroups, and video
conferencing etc.
5.Network gaming
A lot of network games are available,
which allow multi-users to play from
different locations.

18. LOCAL AREA NETWORK
A local area network (LAN) is a group of
computers and associated devices that
share a common communications line or
wireless link.
19. METROPOLITAN AREA NETWORK (MAN)
MAN network covers larger area by
connections LANs to a larger network of
computers.
20. WIDE AREA NETWORK
A computer network that spans a relatively
large geographical area. Typically,
a WAN consists of two or more local-
area networks (LANs).
21. PERSONAL AREA NETWORK

25. Things we need to create a computer network
CABLES AND CONNECTORS
These link together the computers,
printers, servers and other equipment on
your network.
ROUTER
This manages network traffic, ensuring
devices can communicate with each other
via both wired and wireless connections,
and provides internet connectivity.
26. wireless access point (optional)
This will extend your wireless network if
the router is incapable of offering
coverage in certain parts of the building.
Internet Connection
This could be a faster fiber connection
or dedicated leased line.
A Hardware Firewall
This creates a secure barrier between
your network and the internet, blocking
security threats.
27. NETWORK STORAGE SYSTEM
A storage system maintains copies of digital data
across high-speed local area network (LAN)
connection.
It is designed to backup files, databases and
other data to a central location that can easily be
accessed.
28. NETWORK ACCESSED STORAGE
It is file-level computer data storage connected
to a computer network providing data access to
heterogeneous clients. NAS not only operates as
a file server but specialized for the task either by
its hardware , software or configuration of those
elements.
29. STORAGE AREA NETWORK (SAN)
SAN is created by using the fiber channel to link
peripheral devices such as disk storage and tape
libraries.
