Fundamental Objectives of Computer Networks
Data Communication: efficient and reliable information exchange between geographically distributed entities (email, video conferencing platforms).
Resource Sharing: hardware, software, storage
Increase collaboration: collaborative engineering platforms
Reliability and Fault Tolerance: backup systems.
Scalability: ability to grow without redesign Cost Optimization
Distributed Processing: Distributed databases, cloud computing platforms and Parallel AI model training
Mobility and Remote Access: access resources from different locations and enable devices to remain connected while moving.
Example :
AI platforms, IoT ecosystems, cloud computing, and financial systems are examples of modern infrastructures that are essentially network-dependent.
