Basically the task were performed in three ways. Either manually which obviously took forever. In Asia, the abacus ruled. In trained hands it was (and still is) quick and accurate. And then there was the slide rule. My first semester as a math/science major I had to take a full semester class in the use of the slip stick. You could tell the math and engineering majors on campus by the slide rule we all had hanging in holsters on our belts.
Laptop computers, as we now know them, were invented because the existing computers were not portable enough for people of that time. Before lugable/portable/laptop computers came the desktop,er, computer that is. There is still some discussion on who invented Desktop computer with many names mentioned. You would need to go back in History to the Second World War to work out who invented Mainframe computers but some did and they came before desktop computers.
When the electronic digital computer was first invented it had no effect at all on the economy. It took roughly a decade before commercially available computers became available that large companies could afford. It was not until the 1960s that computers began to have significant effects on the economy.
well... can you come up with any better suggestion?The word computer comes from before the digital age, where people who sat in a room doing computations all day were known as computers. Later on the computers we know were invented and were called computers because their main purpose was doing tons of automated computations.A computer system refers to the system of connected hardware which makes up a computer.
Lots of things were invented before computers were available, or in widespread use. Spears, arrows, guns, telescopes, sextants, scales, lightning rods, motion picture, lightbulbs, phonographs, steam locomotives, telegraph lines, radios, combustion engines, and telephones were all created before the first digital computers were available. Television, transistor radios, cassette tapes, disco balls, and penicillin were all created before the first personal computer.
Automatic digital computers were first built during WW2. They were invented in the 1830s by Charles Babbage, but he was unable to build them.Automatic analog computers were built in the 1920s, if not before.Computer history is as old as human history. It started when man started counting and summing with the help of fingers. First device which is known as computer is ABACUS invented 3000 BC. It is still in use in China, Japan, Korea, etc.
