Single-phase and three-phase describe two common ways alternating-current (AC) electrical power is delivered. A technician does not need advanced power-system math to recognize the basic difference: single-phase power uses one repeating AC waveform, while three-phase power uses three AC waveforms separated by 120 electrical degrees. This lesson follows OSETC.012 on grounding and bonding and OSETC.013…

The Windows getmac command displays the MAC addresses associated with network adapters on a computer. A MAC address is a hardware-level identifier used by network interfaces, and technicians often need it when troubleshooting switches, DHCP reservations, device inventory, or adapter identity. Basic Syntax Running the command without options lists the physical addresses detected for local…

The Linux whoami command tells you which user account the current command is running as. It is one of the simplest Linux commands, but it is useful when troubleshooting permissions, working over SSH, using sudo, or checking which account a script is using. Basic Syntax If your current effective user is student, the command prints:…
