They allow organizations to share resources, such as linking company branches into a unified system or connecting multiple devices to a single printer. This fosters a shared work environment and centralized management for geographically dispersed operations. Networks are classified by geographical scope into local (LANs), metropolitan (MANs), and wide (WANs) networks. LANs, limited to a few kilometers, offer high data speeds (10–1,000 Mbps) using technologies like coaxial cables, twisted pairs, or optical fibers. WANs span vast distances, connecting numerous devices and enabling data exchange across regions. Access control is crucial for information system security. It prevents unauthorized access, defines user permissions, and protects system resources, ensuring safe and secure operation while blocking illegal intrusions.
