Computer Network

-

 A compute network is the interconnected infrastructure used to deliver computational resources, including processing power, storage, and networking, often distributed across multiple nodes. It is often associated with cloud computing, data centers, or an edge computing environment.



Components of Computer Network:-

1.Nodes:
Servers, virtual machines, or containers that do the computations.
2.Networking:
The system of nodes that connect to one another for data transfer, typically over high-speed connections like fiber optics or Ethernet.
3.Storage:
Persistent and temporary data storage, such as SSDs, HDDs, or cloud-based storage solutions.
4.Load Balancers:
The distribution of computational workloads across nodes to optimize resource usage and ensure high availability.
5.Management Systems:
Tools and platforms for orchestration (e.g., Kubernetes), monitoring (e.g., Prometheus), and resource allocation.
6.Security Layers:
Firewalls, VPNs, and encryption protocols to protect data and operations.


Application of Computer Network:-

  • Cloud Computing: Those services that provide compute resources such as AWS, Azure, or Google Cloud.
  • High-Performance Computing (HPC): It is used in scientific research, simulations, and analytics.
  • Edge Computing: Process data closer to the source to reduce latency.
  • AI/ML Workloads: Training and deploying machine learning models.
  • Web Applications: Serving and scaling web applications.


Key Terms:-

       1.IP Address: A unique number for a device on the network.

       2.MAC Address: A hardware number unique to the network device.

       3.DNS (Domain Name System): Converts a domain name into an IP address.

       4.HTTP/HTTPS: The protocols used to access websites.

       5.FTP (File Transfer Protocol): For transferring files between devices.


Importance of Computer Networks:-

  • Resource Sharing: Printers, storage, and internet.
  • Communication: by e-mail, video conferencing, and instant messaging.
  • Data Accessibility: Centralized data storage permits access from remote locations.
  • Scalability: Easy to add more devices or users.

  Multimedia tools are essential  to   create  and  manage   different  forms of media  such   as  images, videos, audio, animations, and  other  interactive content. 1.Digital Camera:- A digital camera is an electronic appliance for capturing images in the digital format and storing the photographs and short videos digitally. While a traditional film camera captures light on its film using light-sensitive chemicals, it works with image sensors similar to CCD or CMOS. Uses:- Professional photography. Vlogging and content creation. Travel and landscape photography. Wildlife and sports photography. 2.Camcorder:- A camcorder is a portable, handheld electronic device designed for recording video and audio. It is basically a combination of a camera (to capture images) and a recorder (to save video footage). Camcorders are widely used for personal, professional, and creative projects, ranging from family events to filmmaking. Uses:- ...
