One Third - Desktop PCs

Computers, or PCs, are currently used in almost all fields of human activity. They have become an integral part of our lives. Few, however, would believe that the word "computer" originally referred to a person who performed calculations. The modern definition of the word first occurred when American scientists began work on the production of the first atomic bomb. The term "PC" (personal computer) first entered the lexicon in 1981, with the introduction of the first IBM PC (IBM 5150) to the market.
