Conversely, a LAN speed test isolates the internal environment. It measures the speed at which data travels between devices within the same building—such as between a computer and a Network Attached Storage (NAS) device, a server, or another workstation. The specific build designated as (often associated with version 3.50 of the software) is designed to precisely measure this internal throughput, stripping away internet variables to expose the raw performance of Ethernet cabling, Wi-Fi signals, switch fabric, and Network Interface Cards (NICs).
