Today, hundreds of companies sell personal computers, accessories and sophisticated software and games, and PCs are used for a wide range of functions information about invention of computer basic word processing to editing photos to managing budgets.

At information about invention of computer and at work, we use our PCs to do almost everything. It is nearly impossible to imagine modern life without them. On the outside, ENIAC was covered in a tangle of cables, hundreds of blinking lights and nearly 6, mechanical switches that its operators used to tell it what to do.

On the inside, almost 18, vacuum tubes carried electrical signals from one part of the machine to another. ENIAC and other early computers proved to many universities and corporations that the machines were worth the tremendous investment of money, space and manpower they demanded.

At the same time, new technologies were making it possible to build computers that were smaller and more streamlined. InBell Labs introduced the transistor, an electronic device that carried and amplified electrical current but was much smaller than the cumbersome vacuum tube.

But one of the most significant of the inventions that paved the http://cafeawi.myq-see.com/1390.html for the PC revolution was the microprocessor. Before information about invention of computer were invented, computers needed a separate integrated-circuit chip for each one of their functions. This was one reason the machines were still so large.

The first microprocessor on the market was developed in by an engineer at Intel named Ted Hoff. These innovations made it cheaper and easier to manufacture computers information about invention of computer ever before. However, it really did not do much. It had no keyboard and no screen, and its output was just a bank of flashing lights.

Users input data by flipping toggle switches. The software made the computer easier to use, and it was a hit. This computer, called the Apple I, was more sophisticated than the Altair: It had more memory, a cheaper microprocessor and a monitor with a screen. Also, users could store marketing feasibility data on an external cassette tape. Apple soon swapped those tapes for floppy disks.

For example, a spreadsheet program called VisiCalc made the Apple a practical источник for all kinds of people and businesses —not just hobbyists. The PC revolution had begun. Soon companies like Xerox, Tandy, Commodore and IBM had entered the market, and computers became ubiquitous in offices and eventually homes.

Today, laptops, smart phones and tablet computers allow us to have a PC with us wherever we go. But if you see something that doesn't look right, click here to contact us!

For years, scientists and Http://cafeawi.myq-see.com/1610.html automobile was first invented and perfected in Germany and France in the late s, though Americans information about invention of computer came to dominate the automotive industry in the first half of the twentieth century.

Henry Ford innovated mass-production techniques that became standard, and Ford, The printing press is a device that allows for the mass production of uniform printed matter, mainly text in the form of books, pamphlets and newspapers. Created in China and revolutionizing society there, the press was further developed in Europe in the 15th Century.

When Was InU. Developed in the s and s by Samuel Morse and other inventors, the telegraph revolutionized long-distance communication. It worked by information about invention of computer electrical signals over a wire laid between stations. In addition to helping invent the telegraph, Samuel Morse The American Revolution was fought—and won—with guns, and the weapons have become ingrained in U.

The origin of firearms began with gunpowder and its invention, mostly The automated teller machine, or ATM, is such a complicated piece of technology that it does not have a american cars sale australia inventor.

Instead, the ATMs we use today are an amalgam of several different inventions. Some of these proto-ATMs dispensed cash but did not accept deposits, for The event that laid the groundwork for this monumental change was the introduction of interchangeable parts, or This Day In History. Invention of the PC: Postwar Innovations ENIAC and other early computers proved to many universities and corporations that the machines were worth the tremendous investment of money, space and manpower they demanded.

The Invention of the PC These innovations made it cheaper and easier to manufacture computers than ever before. Inventions: Computers and Internet. Invention of the Automobile. The Assembly Line: Then and Now. Automobile History The automobile was first invented and perfected in Germany and France in the information about invention of computer s, though Americans quickly came to dominate the automotive industry in the information about invention of computer half of the twentieth century.

Printing Press The printing press is a device that allows for the mass production of uniform printed matter, mainly text in the form of books, pamphlets and newspapers. Firearms The American Revolution was fought—and won—with guns, and the weapons have become ingrained in U. Automated Teller Machines The automated teller machine, or ATM, is such a complicated piece of technology that it does not have a single inventor.
