— USB version 2.0 connection.All USB adapters are external, designed for the outer ports of a PC. This method of connection is especially convenient in cases where disassembling the case is undesirable or impossible (for example, if the PC is still under warranty or if it's a monoblock), or if the adapter needs to be frequently reconnected (for example, if Wi-Fi access is periodically needed by different computers in one office). Specifically, USB 2.0 provides speeds up to 480 Mbps and comparatively low power supply, but for wireless adapters, even those capabilities are usually sufficient. Therefore, in such equipment, this version of USB is still the most popular — especially since the adapter can also be connected to a USB port of a newer version (if the ports match or an appropriate adapter is available).
