The proper name for the set of thirteen plugs (called the connector in the specification) and thirteen matching sockets (called the inlet) defined by this specification is IEC-320 Appliance Connectors. They include two and three-conductor plugs of various current capacities and temperature ratings, all designed specifically for the purpose of attaching a mains power supply cord to a piece if equipment.

Almost all personal computers use the ten-amp panel-mounting C14 inlet socket to attach the mains cord to the power supply, as do many monitors, printers and other peripherals. Many computers also provide a panel-mounting C13 outlet for powering the monitor.
A three-conductor cord with a suitable power plug for the territory in which the appliance is used on one end and a C13 plug on the other is commonly called an IEC cord. IEC cords are used to power many other pieces of electronic equipment other than computers, for example instrument amplifiers and much professional audio equipment.
Many electric jugs and similar household appliancess use a cord with a C15 plug, and a matching C16 inlet connector on the appliance. These are similar to the C13 and C14 combination but have a higher temperature rating, 120 degrees celsius rather than 70 degrees.
The C15 cord will fit the C14 receptacle, but the C13 will not fit the C16. That is, you can use a jug chord to power a computer, but not a computer cord to power a jug.
The C15 and C16 connectors have replaced and obsoleted the appliance plug in most applications.C13 and C14 connectors
