No Computors were originally people, usually women who did lots of simple mathematical operations or computations, for businesses or universities, before electronic calculators were invented. When the first electronic mathematical machines were invented they were called computers for short as they did the same job as the workers they later replaced. What you have said is a backronym that came later.
I am sure if the Manitowoc ice machines don't work very well once you buy it, you can return it for a refund. I would look up reviews on them on the computer before buying.
Before computers (which, honestly, has only been the last 20-30 years), accountants used paper and pencil to maintain financial records. There were adding machines and other tools to help ensure accurate mathematical functions as well.
The term Mark I Computer is ambiguous as there were many given this name built in different places by different people. However as almost all of these computers were first generation machines (using vacuum tubes) built before 1960, it is probably safe to say the Mark I Computer was before the Apple Newton.
no it didn't a man made it up completely out of the blue
Before sewing machines people sewed by hand.
Back before the digital machines we have today there was no simple way to do lots and lots of calculations. In order to do so people were hired to sit around and do math all day. These people were known as 'computers.' The name just carried through to the machines which replaced them.
computer is an electronic device which is used for taking the input,processing and displaying the results. Before the concept of electronic compters (pre-1940's), the name 'computer' was given to one who computes. A person, who's job it was to perform mathematical calculations, especially in compiling books of tables.
Primarily they are for time keeping, mechanical clocks and watches all use a type of pendulum.Also:The machines that measure earthquakes used to before sensitive computer boards

The r is there because before they had computers people who did complex mathematical calculations were called computers. They replaced the people b y the machine b ut kept the name.
