Therefore, many restrict the definition of computers to devices whose primary purpose is information processing rather than being a part of a larger system such as a telephone, microwave oven, or aircraft, and can be adapted for a variety of purposes by the user without physical modification.
Typical sorts of instructions supported by most computers are "copy the contents of cell 123, and place the copy in cell 456", "add the contents of cell 666 to cell 042, and place the result in cell 013", and "if the contents of cell 999 are 0, your next instruction is at cell 345".
Computer programs are simply large lists of instructions for the computer to execute, perhaps with tables of data.

 Z1 (computer) - Wikipedia, the free encyclopedia
reproduction of the Z1 The Z1 was a mechanical computer created by Konrad Zuse in 1937.
The Z1 was the first in a series of computers designed by Konrad Zuse.
The computer had a 64 word floating point memory, where each word of memory could be read from and written to by the program punch cards and the control unit.

 Konrad Zuse
The Z1 The Z1 is today considered to be the first freely programmable computer of the world.
Konrad Zuse's first computer, built between 1936 and 1938, was destroyed in the bombardment of Berlin in WW II, together with all construction plans.
Konrad Zuse constructed the Z1 in the apartment of his parents, in fact, he was allowed to use the living room for his construction.

Agli albori dell'era informatica, un computer era considerato una specie di macchina per fare i conti superveloce, la naturale evoluzione delle calcolatrici usate durante la seconda guerra mondiale.
Con il Progetto MAC del MIT, cominciò a studiare gli effetti dell'impiego dei computer su vasta scala: anche se non era possibile affidare una macchina a chiunque, dato il costo, si potevano comunque installare terminali interattivi, che grazie al time-sharing consentivano a molti utenti in contemporanea l'accesso alle risorse del computer centrale.
Dopo aver letto alcuni suoi scritti pubblicati nel 1963, Licklider cominciò a finanziare le ricerche di Engelbart, in quanto riteneva perseguissero i medesimi scopi.

Konrad Zuse is popularly recognized in Germany as the inventor of the computer.
This might be the most important difference between Zuse and other computer inventors working at the time: While in the United States, scientists such as John Atanasoff (1903-) and Howard Aiken (1900-73) had the resources of universities or companies at their disposal, Zuse was working alone.
Zuse's patent application of 1941 for the computing machine Z3 was ultimately refused in 1967 by a German judge, who declared it to lack "inventiveness." The long delay between application and decision was due initially to the war and its aftermath.

On May 31, 1943, the military commission on the new computer began; John Mauchly was the chief consultant and J Presper Eckert was the chief engineer.
The speed of the 701 computers was limited by the speed of its memory; the processing units in the machines were about 10 times faster than the core memory.
All computers then started to be made using chips instead of the individual transistors and their accompanying parts.

 Zuse biography
The main reason why Zuse succeeded in building his mechanical computer where Babbage had failed, was the fact that Zuse's Z1 was a binary machine with two position switches to represent 0 and 1.
Some of Zuse's computers were destroyed in bombing raids near the end of the war although the Z3 was reconstructed in 1960 for display in a museum in Munich.
Finally the Z4 computer was taken to Switzerland where it was installed in the ETH in Zurich in 1950.

 Konrad Zuse's first computers - The Z1
There was a clear separation between the punch tape reader, the control unit (which supervised the whole machine and the execution of the instructions), the arithmetic unit (with registers R1 and R2), the memory, and the input/output devices.
Thus, the saying "War is the father of everything," is not true in the case of the invention of the computer.
The two circles on the left-hand side (on the clock generator block) are cranks for executing a clock cycle manually, where the upper one is for the memory and the lower one for the control and arithmetic unit.

The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention.

 Raul Roja's article on Zuse   (Site not responding. Last check: 2007-11-02)
We argue that both the Z1 and the Z3 possessed features akin to those of modern computers: memory and processor were separate units, the processor could handle floating-point numbers and compute the four basic arithmetical operations as well as the square root of a number.
Konrad Zuse is popularly recognized in Germany as the "father of the computer" and his Z1, a programmable automaton built from 1936 to 1938, has been called the "first computer" in the world.
The computation proceeds as usual, but in each cycle the snooping circuit produces the result -64 at the output of the adder of part A. It does not matter what operations are performed with the significands because the exponent of the result is set to -64 and therefore the final result is zero.

 Domain name system - Wikipedia, the free encyclopedia
To provide resilience in the event of computer failure, multiple DNS servers provide coverage of each domain.
However, because many root servers actually implement anycast, where many different computers can share the same IP address to deliver a single service over a large geographic region, most of the physical (rather than nominal) root servers now operate outside the USA.
The DNS uses TCP and UDP on port 53 to serve requests.
