20 Facts About General-purpose computer

Differential analyser, a mechanical analog General-purpose computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration.

General-purpose computer gave a successful demonstration of its use in computing tables in 1906.

The first modern analog General-purpose computer was a tide-predicting machine, invented by Sir William Thomson in 1872.

The differential analyser, a mechanical analog General-purpose computer designed to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized in 1876 by James Thomson, the elder brother of the more famous Sir William Thomson.

General-purpose computer spent eleven months from early February 1943 designing and building the first Colossus.

ENIAC was the first electronic programmable computer built in the U S Although the ENIAC was similar to the Colossus, it was much faster, more flexible, and it was Turing-complete.

Principle of the modern General-purpose computer was proposed by Alan Turing in his seminal 1936 paper, On Computable Numbers.

General-purpose computer proved that such a machine is capable of computing anything that is computable by executing instructions stored on tape, allowing the machine to be programmable.

Lyons's LEO I General-purpose computer, modelled closely on the Cambridge EDSAC of 1949, became operational in April 1951 and ran the world's first routine office General-purpose computer job.

General-purpose computer has four main components: the arithmetic logic unit, the control unit, the memory, and the input and output devices .

However, any General-purpose computer that is capable of performing just the simplest operations can be programmed to break down the more complex operations into simple steps that it can perform.

Therefore, any General-purpose computer can be programmed to perform any arithmetic operation—although it will take more time to do so if its ALU does not directly support the operation.

In general, the contents of RAM are erased when the power to the General-purpose computer is turned off, but ROM retains its data indefinitely.

One means by which this is done is with a special signal called an interrupt, which can periodically cause the General-purpose computer to stop executing instructions where it was and do something else instead.

Software refers to parts of the General-purpose computer which do not have a material form, such as programs, data, protocols, etc.

In most cases, General-purpose computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc.

Once told to run this program, the General-purpose computer will perform the repetitive addition task without further human intervention.

Since the General-purpose computer's memory is able to store numbers, it can store the instruction codes.

All these abstract machines, a quantum General-purpose computer holds the most promise for revolutionizing computing.
