What caused the inventor(s) of the computer to invent it?
The computer was invented for many reasons, but mainly for solving math problems faster. It was also invented for stocks and trading. At the time that the computer was really needed was in the time period of WWII time to crack secret messages from the opposing countries and to help the countries create new weapons. When people were doing math, it could take them minutes or even hours to do using a slide rule, while a computer could take only seconds to do the same problem. For stocks and trading, the politicians had to use the telephone, paper / snail mail, and over the counter trading. This took too long to complete and had people working too hard to keep up with the market.
What things went into the first US computer and how did they work?
The first electronic computer was the ENIAC, which contained 17468 vacuum tubes. These vacuum tubes were used like a semi-automatic switch to virtually represent the abacus having one bead on one side or another. It also had a surprising 70 thousand resistors (approximately.) Resistors lower the amount of electricity going along in the power current. They were used here to prevent overvoltages in certain parts of the ENIAC. The ENIAC had about 10 thousand capacitors to hold electricity in the machine for a very short time period. This computer contained near 1500 relays along with around 6000 human operated switches. Relays are used to change voltage, like with a thermostat and the air conditioner itself. The human operated switches are used for programming. Hopefully your program isn’t too long for this machine! This computer was hand-soldered and had an estimate of 5 million soldered joints! These joints connect multiple parts of t...

... in 1962: the first video game (Spacewar.) The computer mouse and Microsoft WIndows were both created in the year 1964. The first file sharing system, ARPANET, was released in 1969. The Intel 1903 processor was manufactured in 1971. A very simple storage mechanism called the floppy disc was also made in 1971. The ethernet and networking was created in 1973. The Mark 8 computers and IBM 5100 computers were finished in 1974 and 1975. In 1976 and 1977 the Apple 1, 2 , TRS-80, and Commodo CPD computers were made. The Visicalc spreadsheet software was made in 1978, and in 1979 Wordstar word processing software was launched. The IBM home PC was released in 1981. The MS-DOS Computer Operating System was publicized in 1981 too. In 1983 the Apple Lisa computer was put to sale, and next year the Apple Mac was released. Microsoft and Apple begin a friendly competition in 1985.
In 1939 the very first computer was created by Professor John Vincent Atanasoff and Cliff Berry. It was not the type of computer we are used to though, that type of computer didn’t make an appearance until 1982(Timeline of computer history, 2001). After the first computer was created communication took off like a rocket.
Technology is constantly evolving. Computers, tablets, and cell phones have changed drastically over the past several years. For many years, computers were not available for personal use. Computing machines did not emerge until the 1940’s and 1950’s. Questions about the ownership of the first programmable computer are still disputed today. It appears as if each country wants to take credit for this accomplishment. Computer enthusiasts believe that Great Britain’s Colossus Mark 1 computer in 1944 was the first programmable computer and others give credit to the United States’ ENIAC computer in 1946. However, in 1941, a relatively unknown German engineer built a programmable binary computer. His name was Howard Zuse and his Z3 computer has been acknowledged as the first electromechanical binary programmable computer.
An invention that has been a key component to almost everyone’s everyday life. The first computer was not in any way personal. It was enormous, expensive, and of course inconvenient. It cost roughly 500,000 dollars and weighed around 30 tons. It was invented at the University of Pennsylvania to perform ballistics calculations for the U.S during World War II. Later, new technologies made it possible to make smaller computers. The real innovation for the computer was definitely the microprocessors that could run the computer’s programs, could remember information, and manage data all by itself. This became a revolutionary thing for the military especially. One of the first military grade computers called the 1958 Semi Automatic Ground Environment (SAGE). It used radar stations that tracked sky movements to protect the United States from possible nuclear attacks. It was the brainchild of Jay Forrester and George Valley, which were professors at MIT. SAGE even remained in use until 1983. Computers today have come a long way from weighing almost 3 tons with no personal convenience whatsoever to storing massive amount of information on just a single
Now on to the history of the microcomputer. The first commercially available personal computer was the Scelbi-8H that went on sale in March 1974. The machine was designed around the Intel 8008 microprocessor, a less powerful 8-bit design than the later 8080. A machine in kit form with 1K of memory sold for $440.00. About 200 of these machines were sold in kit form and assembled. Half were the Scelbi-8H hobby machines, the rest were Scelbi-8B business computers, which were released in April 1975, having as much as 16K of memory.

There are many different beginnings to the origins of computers. Their origins could be dated back more than two thousand years ago, depending on what a person means when they ask where the first computer came from. Most primitive computers were created for the purpose of running simple programs at best. (Daves Old Computers) However, the first ‘digital’ computer was created for the purposes of binary arithmetic, otherwise known as simple math. It was also created for regenerative memory, parallel processing, and separation of memory and computing functions. Built by John Vincent Atanasoff and Clifford Berry during 1937-1942, it was dubbed the Atanasoff Berry Computer (ABC).
The original computer was nothing like it is known now. It was a simple device known as an abacus, a mathematic tool that may have been invented in the fourth century BC by the Babylonians (PBS). Before a new computer could be created, a few things had to happen.
Computer has been invented ages ago using the idea of abacus which for reason of calculation. Until today computer still developed to fulfill the will of new generation which want computer to have a simple function and faster in processing the information. It’s also important the style and size of the computer so that the costumer will satisfy with the appearance and size of the computer. Since World War 2 computer already develop its technology but the question asking from 1945.
When you think about the worlds greatest recent invention what usually comes to mind? Many people would say that the personal computer and modern computers in general are the greatest recent invention. This is primarily because the world has experienced a boom in technology recently. You might even be one of the many people that consider the personal computer the best invention. While in recent years they have been used for social websites instead of doing actual computing they are still the greatest tool to man. Computers are used almost everywhere, from schools, homes, workplaces, and practically everywhere. Modern computers were created for military use but engineers had a different view on computers. By the 80s computers were a part of many wealthy households (The Personal Computer). Today it is estimated that per house there are five computers! Imagine how dumb some people feel today saying that computers would never be popular.
The history of the computer goes back hundreds of years. From the abacus through the modern era the evolution of computers has involved many innovative individuals. It was out of this desire to innovate many fascinating tabulating machines developed. The modern computer, therefore, evolved from an amalgamation of the genius of many individuals over a long period of history. Many people shaped the world by making the efforts to develop technology.
... can't be overlooked because it affects everyone on the road. When people text and drive they can't focus on what they are doing so they are more prone to accidents. That's a problem with smart phones and normal cell phones but they still help more than they hurt.
In 1953 it was estimated that there were 100 computers in the world. Computers built between 1959 and 1964 are often regarded as the "second generation" computers, based on transistors and printed circuits - resulting in much smaller computers. 1964 the programming language PL/1 released by IBM. 1964 the launch of IBM 360. These first series of compatible computers. In 1970 Intel introduced the first RAM chip. In 1975 IBM 5100 was released. In 1976 the Apple Computer Inc. was founded, to market Apple I Computer. Designed to Stephen Wozinak and Stephan Jobs. In 1979 the first compact disk was released around 1981 IBM announced PC, the standard model was sold for $2,880.00.
The word 'computer' comes from the word of compute which means to calculate. Computers were developed from calculators as the need increased for scientific calculations and more complex. Charles Babbage is known as the father of computers because of his immense contribution to the programming of the world. His idea was then developed into a programmable computer which could print and calculate logarithmic tables with huge precision. However, there were also some weakness such as practical problems and the progression was slow.
The ENIAC (Electrical Numerical Integrator And Calculator) was the first computer developed in the United States. John Presper Eckert and John Mauchly at the University of Pennsylvania’s Moore School of Electrical Engineering created the Eniac Computer. John Mauchly was the chief consultant and John Presper Eckert was the chief engineer. John Presper Eckert obtained his Bachelor's degree in electrical engineering in 1941 and his Master's degree in 1943, which qualified him to be chief engineer on the project. John Mauchly received his Bachelor's, Master's and Doctorate degree at Johns Hopkins University in Baltimore, Maryland in physics. John Eckert met John Mauchly when he was a graduate student. It took Mauchly and Eckert one year to design and 18 months to build the Eniac.
Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past.
