The History of Computing.
1.What is computing?
Computing is usually defined as the activity of using and improving computer technology, computer hardware and software. It is the computer-specific part of information technology. Computer science (or computing science) is the study and the science of the theoretical foundations of information and computation and their implementation andapplication in computer systems.
2. What was the beginning of computing?
before 1935, a computer was a person who performed arithmetic calculations. Between 1935 and 1945 the definition referred to a machine, rather than a person. The modern machine definition is based on von Neumann's concepts: a device that accepts input, processes data, stores data, and produces output. We have gone from thevacuum tube to the transistor, to the microchip. Then the microchip started talking to the modem. Now we exchange text, sound, photos and movies in a digital environment. 14thC- Abacus, 17thC Slide Rule.
3. Who invented the first computing machine?
Charles Babbage invented the concept of a programmable computer in about 1856.
It partly depends on what you mean by "computer", but the earliestclaim is that Charles Babbage invented the first programmable computer in 1822. The machine was called a "difference engine" and it was intended to generate mathematical tables. This machine contained 25,000 parts and weighed 15 tons. Babbage followed this with a "difference engine 2" which, although well funded, was never completed. Babbage also designed a printer to go along with the computer, butthis also was never completed. In 1989-1991, the London science museum made a difference engine 2 and printer from Babbage's design. Both worked perfectly.
4. When was the beginning of modern computers?
Konrad Zuse (1910-1995) was a construction engineer for the Henschel Aircraft Company in Berlin, Germany at the beginning of WWII. Konrad Zuse earned the semiofficial title of"inventor of the modern computer" for his series of automatic calculators, which he invented to help him with his lengthy engineering calculations.
In 1939, Zuse completed the Z2, the first fully functioning electro-mechanical computer
5. What was the use of the first computing machine?
In 1943, the British completed a secret code-breaking computer called Colossus to decode German messages. TheColossus's impact on the development of the computer industry was rather limited for two important reasons. First, Colossus was not a general-purpose computer; it was only designed to decode secret messages. Second, the existence of the machine was kept secret until decades after the war.
6. Which were the first companies in the computer business?
The relay-based Harvard-IBM MARK I a largeprogrammable-controlled calculating machine provides vital calculations for the U.S. Navy. Grace Hopper becomes its programmer.

7.What is the difference between the old computers and the modern computers?
There are countlessdifferences, between new and old computers. It also depends by what you define as old.
Some examples are:
• New computers are faster and more efficient
• New computers have less hazardous waste
• New computers run cooler and faster
• New computers are also smaller in size
8. Which are the main parts of a computer?
Software refers to parts of the computer which do not have amaterial form, such as programs, data, protocols, etc. When software is stored in hardware that cannot easily be modified
Operating system, library, data, interface, aplication
Hardware: Hardware historically meant the metal parts and fittings that were used to make wooden products stronger, more functional, longer lasting and easier to fabricate or assemble. PC, CPU, MOUSE, etc…
