A WAN, or Wide Area Network, is a telecommunications network that extends over a large geographic area, allowing devices to connect over long distances. The WAN at Priya's workplace connects multiple office locations across India, enabling employees to access shared resources, collaborate on projects, and communicate effectively, regardless of location.

The WAN supports various cloud-based tools and services essential for Priya’s role as a marketing executive. She starts her day by joining a virtual meeting with colleagues from different cities, sharing her screen and collaborating on a new marketing campaign. The WAN provides a reliable and secure connection, ensuring the meeting runs smoothly without interruptions. This network also allows Priya to access large files stored on the company's servers, making data retrieval quick and efficient.

In addition to the WAN, Priya’s office uses a MAN or Metropolitan Area Network. A MAN spans a city or campus, providing high-speed internet access to all office floors. This network is crucial for maintaining fast and consistent internet connectivity throughout the building, supporting various online activities such as video conferencing, cloud computing, and file sharing. The MAN ensures that all employees have access to the resources they need to perform their jobs effectively, regardless of their location within the office.
