,What is a Computer Network?
A computer network is a collection of computing devices connected together to
share resources and communicate with each other.
Networks allow multiple users to:
• Share hardware (printers, scanners)
• Share software (applications, services)
• Exchange data and information
• Communicate in real-time
• Coordinate tasks across multiple locations
Networks range from small connections between two computers to millions of
devices connected globally through the internet.
, Aims and Objectives of Networks
Resource Sharing Communication
Allow multiple users to access the same resources (printers, Enable real-time exchange of information between users, regardless
storage, applications) without duplication, reducing costs and of their physical location, through email, messaging, video calls, etc.
increasing efficiency.
Reliability Scalability
Provide redundancy through multiple connected devices, ensuring Allow for growth and adaptation by easily adding new devices or
continued operation even if one component fails. users to the network as needs expand.
