A network in Information and Communications Technology (ICT) is a system of interconnected computing devices that can communicate and share resources. According to provided information, a network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The physical links can vary.
Key Aspects of a Network:
- Connectivity: Networks establish connections between devices, allowing them to interact.
- Resource Sharing: Networks enable the sharing of resources like printers, scanners, files, and internet connections.
- Communication: Networks facilitate communication between users through email, instant messaging, and video conferencing.
Types of Connections:
Networks can be connected using various methods, including:
- Cables: Physical wires connecting devices.
- Telephone Lines: Using traditional phone lines for data transmission.
- Radio Waves: Wireless communication through radio frequencies (e.g., Wi-Fi).
- Satellites: Using satellites for long-distance communication.
- Infrared Light Beams: Wireless communication using infrared light.
Example Network Scenario
Imagine a small office. Several computers need to share a single printer and access the internet. A network would be set up to allow each computer to:
- Send documents to the printer.
- Access and share files stored on a central server.
- Connect to the internet for email and web browsing.
This network could use Ethernet cables to connect the computers to a central switch or router. A wireless router could also be used, allowing laptops and mobile devices to connect wirelessly via Wi-Fi.
