The objectives and uses of computer networks are:
Resource Sharing: One of the main objectives of a computer network is to allow multiple users to share hardware, software, and data resources. By connecting devices and computers together, users can access shared resources, such as printers, scanners, and files, from anywhere on the network.
Communication: Another important objective of computer networks is to provide a means of communication between users. Networks allow users to send messages, share information, and collaborate on projects, regardless of their physical location.
Cost Savings: Computer networks can help organizations reduce costs by enabling the sharing of resources and reducing the need for multiple devices and services. For example, a networked printer can be shared by multiple users, reducing the need for each user to have their own printer.
Improved Efficiency: Networks can also help improve efficiency by streamlining processes and reducing the time required to perform tasks. For example, a networked inventory management system can help automate inventory tracking and reduce the time required to perform manual inventory checks.
Increased Security: Networks can provide increased security by allowing for centralized management of user accounts and permissions. This can help prevent unauthorized access to sensitive data and resources.
Scalability: Computer networks can be easily expanded as an organization grows, allowing for the addition of new users, devices, and services as needed.
Overall, the objective of a computer network is to enable efficient communication and resource sharing between users, while providing increased security and scalability. The uses of computer networks include file sharing, email, instant messaging, remote access, and online collaboration, among others.
