The first programmable computer built by Konrad Zuse used binary notation for numbers.

The first electronic programmable digital computer, the ENIAC, using thousands of octal-base radio vacuum tubes, could perform simple calculations involving 20 numbers of ten decimal digits which were held in the vacuum tube accumulators.

It has the distinction of being the first programmable ROM cartridge – based video game console, and the first console to use a microprocessor.

The HP-65, the first programmable pocket calculator

The first desktop programmable calculators were produced in the mid-1960s by Mathatronics and Casio ( AL-1000 ).

The first programmable pocket calculator was the HP-65, in 1974 ; it had a capacity of 100 instructions, and could store and retrieve programs with a built-in magnetic card reader.

In 1979, HP released the first alphanumeric, programmable, expandable calculator, the HP-41C.

The first Soviet programmable desktop calculator ISKRA 123, powered by the power grid, was released at the beginning of the 1970s.

The first Soviet pocket battery-powered programmable calculator, Elektronika " B3-21 ", was developed by the end of 1977 and released at the beginning of 1978.

The need to break German codes in World War II led to advances in cryptography and theoretical computer science, with the first programmable digital electronic computer being developed at England's Bletchley Park.

In 1941 Konrad Zuse presented the Z3, the world's first fully functional and programmable computer using electromechanical parts.

In 1943 Tommy Flowers designed and built the Colossus, the world's first fully functional, electronic, digital and programmable computer.

In 1938, Konrad Zuse of Berlin completed the Z1, the first mechanical binary programmable computer, this was however unreliable in operation.

Konrad Zuse, architect of the first programmable computer, which used 22-bit binary floating point.

The underlying principle was noted by the inventor of the first programmable computing device design:

Colossus was the world's first electronic programmable computing device.

Though the ABC machine was not programmable, it was the first to use electronic tubes in an adder.

In 1972, Intel launched the 8008, the first 8-bit microprocessor .< ref > using enhancement load PMOS logic ( demanding 14V, achieving TTL-compatibility by having V < sub > CC </ sub > at + 5V and V < sub > DD </ sub > at-9V )</ ref > It implemented an instruction set designed by Datapoint corporation with programmable CRT terminals in mind, that also proved to be fairly general purpose.

* 1941 – Konrad Zuse presents the Z3, the world's first working programmable, fully automatic computer, in Berlin.

Other technological and engineering feats achieved during, or as a result of, the war include the world's first programmable computers ( Z3, Colossus, and ENIAC ), guided missiles and modern rockets, the Manhattan Project's development of nuclear weapons, operations research and the development of artificial harbours and oil pipelines under the English Channel.

* The Z3 as world's first working programmable, fully automatic computing machine was built.

* Ada Lovelace ( 1815 – 1852 ), the first computer programmer

After the war he worked at the National Physical Laboratory, where he created one of the first designs for a stored-program computer, the ACE.

It was first described in 1837 as the successor to Babbage's Difference Engine, a design for a mechanical computer.

The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete.

In recognition of her additions to Menabrea's paper, which included a way to calculate Bernoulli numbers using the machine, she has been described as the first computer programmer.

J. Presper Eckert and John W. Mauchly similarly were not aware of the details of Babbage's Analytical Engine work prior to the completion of their design for the first electronic general-purpose computer, the ENIAC.

Atanasoff and Clifford Berry's computer work was not widely known until it was rediscovered in the 1960s, amidst conflicting claims about the first instance of an electronic computer.

At that time, the ENIAC was considered to be the first computer in the modern sense, but in 1973 a U. S. District Court invalidated the ENIAC patent and concluded that the ENIAC inventors had derived the subject matter of the electronic digital computer from Atanasoff ( see Patent dispute ).

The machine was, however, the first to implement three critical ideas that are still part of every modern computer:

George W. Snedecor, the head of Iowa State's Statistics Department, was very likely the first user of an electronic digital computer to solve real world mathematics problems.

Judge Larson explicitly stated, " Eckert and Mauchly did not themselves first invent the automatic electronic digital computer, but instead derived that subject matter from one Dr. John Vincent Atanasoff ".

The first model was launched in 1985 as a high-end home computer and became popular for its graphical, audio and multi-tasking abilities.

A prototype of the full computer was shown to the public for the first time at the Summer Consumer Electronics Show in 1984.

Von Neumann wrote the first array-sorting program ( merge sort ) in 1945, during the building of the first stored-program computer .< sup > p.

In computer science, an AVL tree is a self-balancing binary search tree, and it was the first such data structure to be invented.

The Aster CT-80, an early home / personal computer developed by the small Dutch company MCP ( later renamed to Aster Computers ), was sold in its first incarnation as a kit for hobbyists.

It was the first commercially available Dutch personal / home computer.

Most Aster CT-80's ( about 10 thousand of them ) were sold to schools for computer education, in a project first known as the " honderd scholen project " ( one hundred schools project ), but which later involved many more than just one hundred schools.

* The tutorial in the computer game Dystopia takes place in Yggdrasil's first arcology.

* 1981 – The Osborne 1, the first successful portable computer, is unveiled at the West Coast Computer Faire in San Francisco.

This might sound complex, but first of all the number of di-atomic molecules that can exist at the temperatures of the atomizers used in AAS is relatively small, and second, the correction is performed by the computer within a few seconds.

He first gained media attention for breaking into several high-profile computer networks, including those of The New York Times, Yahoo !, and Microsoft, culminating in his 2003 arrest.
