Summary

Networked computers are connected to other devices, allowing them to share resources and communicate with each other. Standalone computers operate independently and cannot interact with other devices.

A Local Area Network (LAN) is a network that connects computers and devices in a small geographical area, like a home, school, or office. It enables efficient sharing of files and printers but is limited in size.

A Wide Area Network (WAN) connects LANs over a broader geographical area, often using the internet. WANs allow communication between distant locations, large geographical areas, but may suffer from slower speeds.

Advantages of networks include resource sharing, increased communication, and collaborative work. However, they also face challenges like security risks, dependence on a central server, and potential data breaches.

Networked computers enable efficient communication and resource sharing, with LANs suited for smaller areas and WANs for connecting larger geographical regions.
