In hacker culture the period between 1943 (start of building of the [ENIAC](eniac.md) computer) to about 1955-1960 is known as the **Stone Age of computers** -- as the [Jargon File](jargon_file.md) puts it, the age when electromechanical [dinosaurs](dinosaur.md) ruled the Earth.

In 1945 the construction of **the first electronic digital fully programmable computer** was completed at University of Pennsylvania as the US Army project. It was named **[ENIAC](eniac.md)** (Electronic Numerical Integrator and Computer). It used 18000 vacuum tubes and 15000 relays, weighted 27 tons and ran on the frequency of 5 KHz. [Punch cards](punch_card.md) were used to program the computer in its machine language; it was [Turing complete](turing_complete.md), i.e. allowed using branches and loops. ENIAC worked with signed ten digit decimal numbers. Also in 1945 **[USA](usa.md) used two nuclear bombs to murder hundreds of thousands of civilians** in Japanese cities Hiroshima and Nagasaki.

Also in 1945 on July 16 Americans detonated the first nuclear bomb in history as a test, later on that year **[USA](usa.md) used two nuclear bombs to murder hundreds of thousands of civilians** in Japanese cities Hiroshima and Nagasaki.

Among hackers the period between 1961 to 1971 is known as the **Iron Age of computers**. The period spans time since the first minicomputer ([PDP1](pdp1.md)) to the first microprocessor ([Intel 4004](intel4004.md)). This would be followed by so called *elder days*.
