Term 285
A loopback plug is a small device used to test network ports by sending a signal out and immediately receiving it back, verifying that the port is working without needing another device.
Term 286
Loose coupling is a design principle where components in a system depend on each other as little as possible, so changes to one part don't force changes in others.
Term 287
A MAC address is a unique hardware identifier assigned to a network interface card that allows devices to communicate on a local network.
Term 288
A machine type defines the virtual hardware resources (vCPU, memory, and sometimes GPU) assigned to a virtual machine instance in a cloud computing environment.
Term 289
