Definition of Computer Network:

A computer network is a group of computers connected together so they can share information and resources. It allows computers to communicate with each other, share files, printers, and access the internet.

Advantages of Computer Networks:

1. Sharing Resources:
   • Computers on a network can share files, printers, and other devices. This means you don’t need to have multiple printers or copies of the same file on every computer.
2. Communication:
   • Networks allow people to communicate easily. You can send emails, chat with others, and share information quickly.
3. Access to Information:
   • With a network, you can access information and resources from anywhere on the network. This means you can work on files stored on another computer without having to physically go to that computer.
4. Cost Savings:
   • Networks can save money because you don’t need to buy separate resources for each computer. For example, instead of buying a printer for every computer, you can connect all the computers to one printer.
5. Centralized Management:
   • Networks allow for centralized management of resources and security. This means administrators can control who has access to what information and easily update software and settings for all connected devices.
6. Increased Efficiency:
   • By sharing resources and information, networks help increase efficiency. Tasks can be completed faster, and collaboration between users becomes easier.
7. Flexibility:
   • Networks provide flexibility for users to work from different locations. With remote access, you can connect to the network and access resources even when you’re not physically present in the office or classroom.
8. Scalability:
   • Networks can easily grow as more computers or devices need to be added. You can expand the network by connecting new devices without much hassle.
9. Backup and Recovery:
   • Networks allow for centralized backup and recovery of data. This means important information can be backed up regularly and easily restored in case of data loss or system failure.
10. Internet Access:
    • Networks provide access to the internet, allowing users to browse websites, research information, and connect with people around the world.
