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 ...
ENIAC ( / ˈɛniæk /; Electronic Numerical Integrator and Computer) [ 1][ 2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3][ 4] Other computers had some of these features, but ENIAC was the first to have them all.
Dimensions. 24 in × 12.5 in × 6.5 in (61 cm × 32 cm × 17 cm) 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 ...
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 .
Grace Brewster Hopper ( née Murray; December 9, 1906 – January 1, 1992) was an American computer scientist, mathematician, and United States Navy rear admiral. [ 1] She was a pioneer of computer programming. Hopper was the first to devise the theory of machine-independent programming languages, and used this theory to develop the FLOW-MATIC ...
In 1912, British engineer Arthur Pollen developed the first electrically powered mechanical analogue computer (called at the time the Argo Clock). [citation needed] It was used by the Imperial Russian Navy in World War I. [citation needed] The alternative Dreyer Table fire control system was fitted to British capital ships by mid-1916.

The military time zones are a standardized, uniform set of time zones for expressing time across different regions of the world, named after the NATO phonetic alphabet. The Zulu time zone (Z) is equivalent to Coordinated Universal Time (UTC) and is often referred to as the military time zone. The military time zone system ensures clear ...
