User error

A user error is an error made by the human user of a complex system, usually a computer system, in interacting with it. Although the term is sometimes used by human–computer interaction practitioners, the more formal human error term is used in the context of human reliability.

Related terms such as PEBCAK (Problem Exists Between Chair And Keyboard), ID-10T error (idiot error), and other similar phrases are also used as slang in technical circles with derogatory meaning.[1] This usage implies a lack of computer savvy, asserting that problems arising when using a device are the fault of the user. Critics of the term argue that the problems are caused instead by a device that doesn't take into account human limitations and is thus designed in a way that induces errors.

The term can also be used for non-computer-related mistakes.

CPU socket

A CPU socket or CPU slot is a mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the CPU to be placed and replaced without soldering.
