The ENIAC, generally considered as the first electronic computer, was built from 1944 to 1946 inside the University of Pennsylvania campus. The US Army then had under its employ hundreds of mathematically-gifted young women who were tasked to manually do the computations for the ballistics tables used for military weapons. Hundreds of women, all with math capability, were then serving in the US Army as human computers, doing ballistic tables for military weaponry.
To distinguish, the term computer hardware includes all the tangible parts of a computer, while computer software refers to things related to the computer that can't be touched.

A lot of people are of the mistaken notion that devices such as a flash drive and CD that are generally used to keep data and software programs are under the software category, although they are technically hardware that are merely used to protect and keep software and data.

This is because there were no batteries that were small enough for these phones then. It was in 1973 when the Motorola Company embarked on the development of the first handheld mobile phone in the US. Today, these phones are known by their ubiquitous monicker Brick Phones.
