ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.
The first computer like ours first was invented by Charles Babbage.
Approximately 35,000 B.C
A small piece of the fibula of a baboon, marked with 29 clearly defined notches, may rank as the oldest mathematical artefact known. Discovered in the early seventies during an excavation of the Border Cave in the Lebombo Mountains between South Africa and Swaziland, the bone has been dated to approximately 35,000 B.C. In a description of the bone, Peter Beaumont, an archaeologist who has done extensive work on Border Cave, has noted that the 7.7 cm long bone resembles calendar sticks still in use today by Bushmen clans in Namibia.

The abacus was probably invented in the Middle East. In the West, from early Roman times, users calculated with a "table abacus" that involved manipulating coin-like discs, or "jetons," on lines drawn on a table or cloth. The table abacus remained in use in parts of Britain and northern Europe until the late 1600s.
In the East, several Asian civilizations used a technique similar to the table abacus until about 1200 AD when the more familiar wire and bead abacus was created in China. As late as 1946, the US Army newspaper Stars and Stripes sponsored a contest pitting a Japanese abacus against an electric calculator. The abacus won.

Charles Babbage developed the "Difference Engine," a mechanical device that could perform error-free calculation of polynomial functions. He completed only a small model before the British government withdrew funding, forcing him to abandon the project. Soon after, Swedish scientists Georg and Edvard Scheutz would complete a working version.

Konrad Zuse developed functioning program-controlled computing machinery as early as 1936 and went on to form a successful European computer business in the 1950s

Difference engines were forgotten and then rediscovered in 1822 by Charles Babbage. This machine used the decimal numbers system and was powered by cranking a handle. The British government first financed the project but then later cut off support. Babbage went on to design his much more general analytical engine but later returned and produced an improved design (his "Difference Engine No. 2") between 1847 and 1849.
Others point out that this is the first ELECTRONIC computer. The earliest computer known is the Antikythera Machine, a mechanical device that computed the positions of the astrological signs on any given date, past or future. It was discovered in an ancient shipwreck in the Mediterranean Sea and dates to approximately 250 BC. The designer/builder is not known, but because of its similarity to other mechanical devices known to have been designed by Archimedes, it is probably his work.
Still others will say the abacus is the first computer. They were invented by the Chinese between 2400 BC and 300 BC is considered as the first computer ever. Abacus was used by the merchants and Clerks in China.
Here is still more input:
The first known counting devices or tools were Tally Sticks from about 35,000 BC.
The Abacus was then invented by the Babylonians in 2400 BC.
In 1837, Charles Babbage, a British professor of mathematics described his idea for the Analytical Engine, the first stored-program mechanical computer.
That is very difficult to answer as the term computer has changed quite vastly over the ages. I would have to say that IBM created the first computer that really resembles that which we call one today in 1944 The Harvard Mark I- IBM ASCC, the inventor was Howard H. Aiken.
To add to the previous answer - in 1937 the English mathematician Alan Turing came up with a theoretical design for a computer. In 1939-40 he designed the "Colossus" - the computer used to break the German "Enigma" code during WW2. The principle of Colossus was the same as all computers since then, using on/off circuits to evaluate true or false conditions.
Colossus was built and used to crack the German teletype based "Fish" codes, not "Enigma". "Enigma" was broken using electro-mechanical machines called "Bombes".
John Vincent Atanasoff is credited as inventing the electronic computer. He finished building it in early 1942, however it was not programmable unlike the later electromechanical Harvard Mark I.
In 1822, Charles Babbage purposed and began developing the Difference Engine, considered to be the first automatic computing engine that was capable of computing several sets of numbers and making a hard copies of the results.
Honestly this is not an easy question to answer. I guess you would first have to define what a computer really is. One common and widely agreed upon definition of a computer is: a devices which inputs, processes, and outputs data or information. If that's the definition you're going with then no one really knows because there have been ancient artifacts of devices found in ruins of past cities and settlements that input, process and output data. By this definition, no these computers were not able to run Windows of Mac or play games but they did serve functions such as map planetary alignment and position of the planets and geographical location.
I would look up old computers and/or ancient computers in Google and other search engine websites to get a better understanding of this.

Charles Babbage in vented the computer
No, they had been invented but not for the use of private persons.
no not no
Apple Computers.
Revie Hopper invented the Name Toshiba in 1999.
No one knows for sure.
In 1675 Anton Van Leeuwenhoek did.
well the Greeks invented it, but the persons name is unknown.
No one person invented it. it originated from many different people as well as cultures.
not one person ivented the firework...Mcay.
Charles Paulson Ginsburg
It is hard to figure out who invented the firework because it was invented around 206 B.C. to 220 A.D.
Mike Dell invented Dell computers.
