Actually, the first computers used were completely mechanical ones, several hundred years ago (or thousands, I can never remember which). Basically what they would do is punch in an equation, and turn a crank for a long long time. It would give an answer in a certain amount of time, depending on just how complicated the problem was.
What you're probably looking for, though, are the mechanical computers back in the sixties, where a bunch of mechanical parts would change pixels on a tiny screen.
The earlliest computer were made for doing millions of calucaltions
So that weather forcasting could be done
Calculating, storing numbers and later on word processing.
The earliest computers were used to construct nautical tables. Then the next big use was in decrypting German codes during WW2.
Computers were used for working purposes.
Computing artillery firing tables.
Electro-Mechanical Computers were used before first generation of computers.
no, first generation computers used vacuum tubes.
This is the term used for big vacuume tubes which were used in the construction of first generaiton of computers.
No, generally the first computers were too expensive for businesses to afford.
They are first generation computers because they used vacuum tubes as active elements, as did almost all computers until 1958 when the first generation is usually considered to have ended. From 1958 on most computers used discrete transistors as active elements until 1964.Note: ABC & ENIAC are both very early first generation computers as they used ordinary Radio receiver vacuum tubes, not the more expensive Computervacuum tubes that were introduced about 1948 to 1949. The later Computer vacuum tubes were custom redesigned versions and were far more reliable than ordinary Radio vacuum tubes had been.
digital computers were first used in 1942 analog computers were first used in about 100BC
