What enables high-speed data communication between computers within the same geographic area?

1. Wide Area Network (WAN)

2. Local Area Network (LAN)

3. Extranet

4. Virtual Private Network (VPN)

The correct answer is: Local Area Network (LAN)

High-speed data communication between computers within the same geographic area is typically facilitated by a Local Area Network (LAN). A LAN is designed to interconnect devices within a limited area, such as a home, office, or building, allowing for fast data transfer rates, typically ranging from 100 Mbps to several Gbps. Furthermore, LANs support numerous networking technologies, including Ethernet and Wi-Fi, which can create reliable and efficient communication channels among connected devices. Other options present different networking concepts. A Wide Area Network (WAN) covers larger geographic areas and is more suited for connecting multiple LANs, but does not primarily enable high-speed communication in close proximity. An Extranet extends a private network to outside users and is useful for business collaborations but is not specifically designed for high-speed communication within a localized environment. A Virtual Private Network (VPN) provides secure, encrypted connections over the internet for remote access to a LAN or private network but introduces some latency and is thus not aimed at high-speed communication within a specific geographical locale.
