The Apollo Guidance Computer ( AGC) was a digital computer produced for the Apollo program that was installed on board each Apollo command module (CM) and Apollo Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft. [ 3] The AGC was the first computer based on silicon ...
Time synchronization in North America can be achieved with many different methods, some of which require only a telephone, while others require expensive, sensitive, and rare electronic equipment. In the United States, the United States Naval Observatory provides the standard of time, called UTC (USNO), for the United States military and the ...
The 24-hour clock is used in military, public safety, and scientific contexts in the United States. [4] It is best known for its use by the military and is therefore commonly called "military time". In U.S. military use, 24-hour time is traditionally written without a colon (1800 instead of 18:00).
Some American bases are also NATO-led with forces from multiple countries. According to the U.S. Army, Camp Humphreys in South Korea is the largest overseas base in terms of area. [99] Most of foreign military installations are located in NATO countries, Middle East countries, South Korea and Japan. Countries with U.S. bases include:
Accompanied by a time announcement, this phrase is typically used as a direct introduction for the originating station's late-evening newscast, typically at either 10:00 p.m. or 11:00 p.m. [1] While the phrase itself had appeared in newspapers as early as the 19th century, usage of it in broadcasting started in the early 1960s following the ...
Real-time clocks are electronic devices designed to provide system time, and thereby wall-clock time, to a computer system. (Contrast this with clock signals, designed to provide timing for electronics themselves.) See also. Category:Clock signal for the topic of internal electronic clocking signals
The most common that people know of is the PC as created by IBM. Many military computer systems are built around alternative plug-in bus structures such as VMEbus or Compact PCI. A military computer may not provide for plug-in cards and be in a dedicated form factor for a specific application such as installation on a UAV such as the Global Hawk .
Time clock. A time clock, sometimes known as a clock card machine, punch clock, or time recorder, is a device that records start and end times for hourly employees (or those on flexi-time) at a place of business. In mechanical time clocks, this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock.
