The first computer was an Chinese abacus.
A computer is defined as A device that computes that assembles, stores, correlates, or otherwise processes information.
An abacus is a manual computing device consisting of a frame holding parallel rods strung with movable counters.
Word History: The adjective dusty, with its connotations of disuse and age, might seem an appropriate word to describe the abacus, since this counting device was used for solving arithmetical problems in the days before calculators and computers. Originally the abacus was, in fact, dusty. The source of our word abacus, the Greek word abax, probably comes from Hebrew 'bq, "dust," although the details of transmission are obscure. In postbiblical usage 'bq meant "sand used as a writing surface." The Greek word abax has as one of its senses "a board sprinkled with sand or dust for drawing geometric diagrams." This board is a relative of the abacus with movable counters strung on rods that is familiar to us. The first use of the word abacus, recorded in Middle English in a work written before 1387, refers to a sand-board abacus used by the Arabs. The difference in form between the Middle English word abacus and its Greek source abax is explained by the fact that Middle English borrowed Latin abacus, which came from the Greek genitive form (abakos) of abax.
I did a little research and found the first personal computer was called, "Simon" (not to be confused with the popular game). It was developed by Edmund Berkeley. He first wrote about the idea in his book, "Giant Brains, or Machines That Think," published in 1949. The construction of the machine was conducted mostly by, William A. Porter and Robert A. Jensen. The purpose of the machine was to create a mechanical brain that could create interest for others to make more creations of its kind. The machine could perform some functions like a calculator addition and subtraction. Source: http://www.blinkenlights.com/pc.shtml
The first computers were designed to calculate mathematical tables. These tables were used for navigation and being calculated by hand made them error prone. These first computers were mechanical difference engines. The first electronic computers were built during WW2 to decode German encrypted transmissions.
The first electronic digital computer, ABC completed in 1942, was used to solve systems of simultaneous equations for the University's Statistics department in Ames Iowa.
It could do up to 30 additions/subtractions per second on 50 bit binary numbers. Data was entered in decimal on conventional IBM punchcard (inserted manually one at a time), intermediate results were punched/read using electric sparks on standard 8.5 by 11 sheets of paper, 30 numbers of 50 bits each per sheet. Final results were read out on an electromechanical counter device.
Super Computers
Computers were first invented to perform calculations that were complex or repetitive in nature, in order to make human life easier.
Computers perform several functions over and over that include processing. They transmit data repeatedly when in use. Computers continually store or save data.
On the first computers, without an operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral-2like printers and card-readers. Not every computer had an operating system.
perform calculations according to a program, just like modern computers.

Commands tell computers what tasks they should perform. Software installed on computers provide the commands users need to complete tasks on computers.
to perform tedious calculations
Computers are useful, but not powerful because they depend on the human intelligence to perform some tasks.
Super Computers
Calculus is a form of math. Computers are devices (or persons) that perform math.
It already has; binary.
computers that perform ariyhmatic operations directly
The first computer functioned very quickly, by comparison with the work of people trying to perform the same calculations. However, by comparison with modern computers, the first one was painfully slow.
Computers were first invented to perform calculations that were complex or repetitive in nature, in order to make human life easier.
IT COULD BE BECAUSE THE COMPUTERS ARE WORKING WELL IN THE WORLD AND THE FUTURE COMPUTERS COULD BE BETTER THAN THE OLD ONES or it could be the same
Computers in the 40's were used to perform calculations for the military of the country that developed it. The Z3 in Germany was the first such computer, with the American Harvard-IBM MARK I and ENIAC, along with the English Colossus coming soon after that.
