- Purpose: The primary purpose of a MAN is to connect multiple LANs within a city, facilitating efficient data transfer and communication among them.
- Components: MANs typically consist of switches, routers, fiber optic cables, and access points, ensuring seamless data flow.
- Advantages: MANs provide cost-effective networking solutions, high bandwidth, low latency, and secure data transmission within metropolitan areas.
- Applications: They find use in educational institutions, healthcare facilities, government offices, and various businesses, enhancing connectivity and communication.
