A collection of networks within a Metropolitan area is called what?

• A. Metropolitan Area Network (MAN)
• B. Multicast
• C. Modem
• D. Masquerading

Answer: (A)

In networking, terms are often organized by the geographic area they cover. A collection of networks within a city or metropolitan region is called a Metropolitan Area Network. A MAN connects multiple LANs across a city, providing higher-speed links than a typical LAN but covering a smaller area than a WAN that spans larger distances. It’s commonly used to interconnect campuses, offices, or city-wide service provider networks using fiber or wireless connections. The other terms don’t describe geographic scope: multicast is a method for delivering data to many recipients, a modem is a device that modulates signals for transmission, and masquerading refers to hiding internal IP addresses (NAT) rather than naming a network by area.
