Who Invented A Computer ?

Computer as we see it today was never invented by a single individual,it spanned through generations of developing existing prototypes/algorithms invented by past generations of inventors.
Although through the years,every Inventor to be mentioned below extended the prototype of someones invention to develop his own prototype/algorithm and through the generation of their prototype a birth of a computer was ultimately born
Charles Babbage, an English mechanical engineer and polymath, originated the concept of a programmable computer. Considered the "father of the computer", he conceptualized and invented the first mechanical computer in the early 19th century. After working on his revolutionary difference engine, designed to aid in navigational calculations, in 1833 he realized that a much more general design, an Analytical Engine, was possible. The input of programs and data was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms such as the Jacquard loom. For output, the machine would have a printer, a curve plotter and a bell. The machine would also be able to punch numbers onto cards to be read in later. The 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.

The machine was about a century ahead of its time. All the parts for his machine had to be made by hand — this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with the decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to difficulties not only of politics and financing, but also to his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage, completed a simplified version of the analytical engine's computing unit (the mill) in 1888. He gave a successful demonstration of its use in computing tables in 1906

Augusta Ada King-Noel, Countess of Lovelace  was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and created the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer.

Alan Mathison Turing  was an English computer scientist, mathematician, logician, cryptanalyst, philosopher and theoretical biologist.
He was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.

Konrad Zuse was a German civil engineer, inventor and computer pioneer. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse has often been regarded as the inventor of the modern computer.

John Vincent Atanasoff was an American physicist and inventor, best known for being credited with inventing the first electronic digital computer.
Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College. Challenges to his claim were resolved in 1973 when the Honeywell v. Sperry Rand lawsuit ruled that Atanasoff was the inventor of the computer. His special-purpose machine has come to be called the Atanasoff–Berry Computer.

John William Mauchly  ) was an American physicist who, along with J. Presper Eckert, designed ENIAC, the first general purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States.
Together they started the first computer company, the Eckert-Mauchly Computer Corporation (EMCC), and pioneered fundamental computer concepts including the stored program, subroutines, and programming languages. Their work, as exposed in the widely read First Draft of a Report on the EDVAC (1945) and as taught in the Moore School Lectures (1946), influenced an explosion of computer development in the late 1940s all over the world.

Stephen Gary "Steve" Wozniak  is an American inventor, electronics engineer, programmer who co-founded Apple Inc. He is known as a pioneer of the personal computer revolution of the 1970s and 1980s, along with Apple co-founder Steve Jobs.
Wozniak single-handedly developed the 1976 Apple I, which was the computer that launched Apple. He primarily designed the 1977 Apple II, known as one of the first highly successful mass-produced microcomputers
