The first computer that resembled the modern machines we see today was invented by Charles Babbage between 1833 and 1871. He developed a device, the analytical engine, and worked on it for nearly 40 years. It was a mechanical computer that was powerful enough to perform simple calculations.
The first internal computer speaker was invented by IBM in 1981 and produced basic, low quality sound. As technology progressed, onboard speakers moved into the computer monitor and acquired the ability to produce voices, music, and other sound effects. Monitor speakers were on the bottom-left and bottom-right on the front of the monitor.
The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done, giving rise to punch-card based
Deep inside this 73-year-old lies a microprocessor - a tiny computer that controls his pacemaker and, in turn, his heart. Microprocessors were invented by - Ted Hoff, along with a handful of visionary colleagues working at a young Silicon Valley start-up called Intel. This curious quirk of fate is not lost on Ted.
A Complete History of Computers: From the 1800s to Now
Early computers would use similar punch cards. 1822: Thanks to funding from the English government, mathematician Charles Babbage invents a steam-driven calculating machine that was able to compute tables of numbers. 1890: Inventor Herman Hollerith designs the punch card system to calculate the 1880 U.S. census.
It is also known that the first electronic computer was designed by an unknown inventor. But because this innovation was akin to those of Archimedes, it is believed he was the inventor is this computer, which was known as the Antikythera Machine. This constituted one of the objects found in the remains of a wreck, approximately about 250 BC in the Mediterranean Sea.

More complex calculating and tabulating machines evolved in the early twentieth century, until the first general purpose electronic computer, the ENIAC (Electronic Numerical Integrator and Computer), was developed in 1941-1945. Soon after the invention of the computer was the discovery by Grace Hopper of the first computer bug, a moth trapped in a relay of the Harvard University Mark II Aiken Relay Calculator on 9 September, 1945.
But during the 70s, computers were available only in electronic shops. Most of them made use of switches and panels. The keyboards and disks had to be purchased separately. The Micral is regarded as the first non assembly, commercially available computer. It used the Intel 8008 processor.
Computer - Wikipedia
This usage of the term referred to a human computer, a person who carried out calculations or computations.
The father of the modern computer is the scientist Charles Babbage. He was simultaneously an English instrumentalist, mathematician, inventor and philosopher. Charles Babbage was born in 1891 in London. He invented the first mechanical device in 1810 to calculate numbers and tables.

Who Invented the Laptop? | Meeting Tomorrow
Who Invented the Laptop? The laptop computer revolutionized the way people work and travel nearly as much as the original computer did. Alan Kay, who worked for Xerox PARC, first created the concept for the laptop computer. He referred to it as the Dynabook. Xerox PARC did come up with a working model of the Xerox Note Taker in 1976, but it was not available to the public.
Who Invented Electricity? Nobody actually invented electricity, but its existence and uses have been discovered by a variety of people. Electricity occurs for a number of reasons including electrical charges in subatomic particles, electrical currents flowing through electrically charged particles, electric fields which are produced without a current, electrical potential which is the capacity of an electric field to work on a charge, and electromagnetics, which is the exchange between magnetic fields and currents.
There is not an easy answer to who invented the television. The idea of having something that transmits moving images existed long before the first television was built. In the late 19th century, a couple of scientists made pivotal discoveries, without which the first television would not have existed.
Of course there are disinters in the opinion of who invented the computer. The neighbor of Jerry Seinfeld, John Von Jovi Newman is one candidate often mentioned. Another candidate that is thrown out like a baby in bathwater is Vincent Van Gogh Atanasoff. Even the great Tim Berners-Lee Meriwether has been tossed about as a candidate as well.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge ruled that the ABC computer was the first digital computer, many still consider the ENIAC to be the first digital computer because it was fully functional.
It was in 1936 when the first computer was invented and developed by the most promising creation of Konrad Zuse. Though it has been claimed that there were devices prior to it but it was the first ever made for programming. It was then the beginning of break through of computers when they further developed computer known as Harvard Mark I in 1944 through ABC Computers company owned by John Atanasoff.
In 1943, Tommy Flowers invented the first programmable electrical computer, and it was called Colossus, where Flowers invented this machine to help the British army decipher the encrypted messages of the German army. In the period between 1943 and 1944 CE, two professors at the University of Pennsylvania built the Eniac computer, which occupied an area of 800 square feet and contained a vacuum valve (in English: the vacuum tube), and this device is considered the grandfather of computers.
Similar ideas were brought forth by other inventors across the world, among them Paul Otlet, Henri La Fontaine, and Emanuel Goldberg, who created the first dial-up search engine that functioned through his patented Statistical Machine. Then, in the late 1960s, the previously theoretical ideas finally came...
