Typical POST screen (AMI BIOS) Summary screen after POST and before booting an operating system (AMI BIOS) A power-on self-test ( POST ) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on.
Two POST seven-segment displays ("Q_CODE1" and "Q_CODE2", lower-left), integrated on a computer motherboard. Diagnostic cards are today mainly used by designers of motherboards and extension cards, along with logic analyzers and other debug tools and interfaces.
A selection of Apple devices, including various iPhone, iPad, and iPod Touch models; all of which are considered to be examples of "post-PC devices".. The post-PC era was a market trend observed during the late 2000s and early 2010s involving a decline in the sales of personal computers (PCs) in favor of post-PC devices; which include mobile devices such as smartphones and tablet computers as ...
A Post–Turing machine [1] is a "program formulation" of a type of Turing machine, comprising a variant of Emil Post's Turing-equivalent model of computation. Post's model and Turing's model, though very similar to one another, were developed independently. Turing's paper was received for publication in May 1936, followed by Post's in October.

The mail or post is a system for physically transporting postcards, letters, and parcels. [1] A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly , with a fee on the article prepaid.
BIOS POST has initialized the system timers, interrupt controller(s), DMA controller(s), and other motherboard/chipset hardware as necessary to bring all BIOS services to ready status. DRAM refresh for all system DRAM in conventional memory and extended memory, but not necessarily expanded memory, has been set up and is running.
