Who Invented the First Apple Computer?

Who Invented the First Apple Computer?...

The first Apple computer was conceived by Steve Jobs and Steve Wozniak and sold on July 1976. It consisted of a motherboard, memory and CPU. The history of Apple computer shows the company was incorporated a few months after the Apple I went on sale. Early History The Apple I sold very well and inspired Wozniak and Jobs to develop the Apple II. The Apple II came with a 5 ¼ floppy drive and employed color and graphics. The machine was even more successful than the Apple I. The Apple II was bought by educators and hobbyists. Soon the Apple II became a mainstay in schools where computers were being taught. Another welcome feature of the Apple II was its open architecture. This design allowed third party vendors to create applications for the computer. The history of Apple computer shows that by 1978, the machine had also become a mainstay in business offices. This was due to the appearance of various third party business applications on the Apple II. The Lisa and the Macintosh The Apple II was followed by the Apple III which was a commercial failure. The computer improved very little from its predecessor. It also had a number of technical glitches that affected its performance. The company was also unable to make gains on the business front. It would lose its business market share to IBM. In response, Steve Jobs went to Pao Alto Research Laboratory, run by Xerox. There he was able to recruit its most brilliant researchers. It was this team of researchers who designed the GUI (graphical user interfaced), pull down menus and the use of a mouse. This would be an important point in the history of Apple computer. In 1983, the...
Who Invented the Cell Phone?

Who Invented the Cell Phone?...

The mobile or cell phone was invented by Martin Cooper in 1973. The history of the cell phone shows that Nathan Stubblefield had a patent in 1908. However the patent was for cave radio phones and not the mobile device as we know it today. Early History As stated, Stubblefield’s patent was for cave radio telephones, as the device was known then. The mobile phone’s origin can be traced back to the 1940s. Bell Labs had already made some mobile base stations. These were refined in the 1960s but they were mainly for radio telephony. The main users of radio telephony during those days were the military. These hand held radio gadgets had been patented in 1969 to George Sweigert. The history of the cell phone began in 1945 and these early phones are now called zero generation phones. It consisted of a solitary base that would cover a specific spot and had very limited coverage. First Generation Phones Cooper’s invention was patented on October 17, 1973. the first phone call was made by Cooper months before he applied for the patent, on April 3, 1973. He made the call to Dr. Joel Engel, a researcher at AT&T’s Bell Labs. Cooper was working at Motorola at the time, and the call was made with several media people present. Soon after, companies started making cellular networks. Although the telephone was still dominant, other companies started coming out with cell phones, although they were still large and heavy. Second Generation Phones The next stage in the history of the cell phone was the development of 2G (second generation) phones. Among the earliest 2G phone systems were GSM, IDEN, and IS-95. GSM networks started appearing in 1991 (specifically in Finland). Compared with...
Who Invented the Trash Compactor?

Who Invented the Trash Compactor?...

There is no single inventor of the trash compactor. An assessment of the history of the trash compactor shows there are actually several inventions that led to the compactors as we know them today. The Earliest Trash Compactors Most machines use hydraulics to crush compress garbage. Using this definition of a trash compactor, the earliest patent would belong to M. S. Wells. In 1941 he patented an invention to compact oil cans. The mechanisms of his device are similar to the ones used by other trash compactors. This was followed by other inventions. The succeeding ones would improve or add features to the basic compactor. One well known patent is for the Kitchen Compactor. This apparatus was designed by one Mr. Boyd. A study of the history of the trash compactor will reveal that it adheres to the basic principles of trash compactors. In his application, Mr. Boyd declared the machine would use hydraulic pressure to compact trash. This apparatus had to be linked to the water line before it could be used. Boyd’s invention was for houses. That same year Stephen Hopkins came out with a trash compactor for apartments and offices. It did not need a water line to work. Instead it relied on electricity and an internal hydraulic unit. Both Boyd and Hopkins worked for the same company, Compackager Corporation. The Modern Trash Compactors The history of the trash compactor since the 1970s is noted for numerous improvements and innovations. The kitchen compactors today have noise reduction features built in. The pistons used in these devices have also become more powerful and more efficient. In addition, specially designed trash bags have been made for these compactors. Elements like sensors, pre determined pressures and load relievers have...
Who Invented the Clock?

Who Invented the Clock?

Who invented the clock? Introduction Many types of clocks are in use today. Each kind has its own inventor and history. But from the beginning, men have used all kinds of objects and materials to be able to keep time. Here are the different types of clocks used and how they were made. Astronomical Calendars When men looked up at the sky, they noticed that the sun, moon, stars and other heavenly bodies moved in cycles. This allowed them to tell time. The Sumerians used a solar calendar with 30-day long months and 12 periods in each day. The famous Stonehenge in Britain was an ancient timekeeping monument. It marked various astronomical and seasonal events like eclipses, equinoxes, etc. The Egyptians first used a lunar calendar, just as the Chinese did. Later the Egyptians invented a 365-day solar year based on when the Dog Star Sirius would rise near the sun. The Mayans had a very accurate calendar too. They used not only the sun and moon, but also the planet Venus. Sun and Water Clocks Ancient peoples had other ways to tell time. The Egyptians invented the obelisk. Its shadow was used to mark the hours of the day. This was a type of sundial. Another kind of clock was the water clock. Different models of water clocks existed. The oldest was a vessel with a hole at the bottom. The vessel was filled with water and it would pour out at a constant rate. The Chinese made use of water clocks to time the fertility of the emperor’s consort. The Pendulum Clock The first accurate, modern clock was the pendulum clock. It was invented in 1656 by a Dutch scientist, Christian Huygens. When he first built the...
Who Invented Atari?

Who Invented Atari?

The history of Atari began in 1972 when the company was founded by Nolan Bushnell and his associate Ted Dabney. Originally the firm was called Syzygy but Bushnell later changed it to Atari. Beginnings and Early Success A year before the company was founded Bushnell hired Al Alcorn to recreate the Odyssey game Tennis for Two. The result was Pong. When the game was released in 1972, it became a huge hit. The Atari Company was founded that same year (the word Atari means go in Japanese. Sometimes it is also translated as to hit the target). The success of Pong (150,000 copies sold) marked a significant turning point in the history of Atari. In 1975, Bushnell sold the company to Warner Communications. It was under Warner that the gaming platform attained success. The Atari 2600 was so popular the sales made up a third of Warner’s profit for the first few years. In 1980 the Atari home video system made nearly half a billion dollars in sales. The 1983 Crash In 1983 sales of video games plummeted in the United States. Atari losses amounted to over $550 million. The following year Warner handed over Atari to Jack Tramiel (former head of Commodore). The Atari St came out and sales peaked at $25 million in 1986. Struggles The next stage in the history of Atari involved its struggles with rival Nintendo. Their rival was winning market share so Atari worked on the Lynx system. It was a handheld console complete with color. The Lynx sold poorly for two reasons. Number one, shortage of components prevented it from being released during the 1989 holiday season. Second it cost twice as much as the Nintendo Game Boy. Tramiel had also stressed...
Who Invented the Digital Camera?

Who Invented the Digital Camera?...

A digital camera is a type of camera that takes photographs or videos with the use of an electronic image sensor. This device has the capacity to display photographs on the screen several seconds after the image has been recorded. Other brands of the cameras can edit the layout, color as well as the entire appearance of the picture. Because of the popularity and wide use of the device, it is incorporated in other devices like mobile phones and PDAs. To learn about the history of the device, it is best to start with the person behind the development of the digital camera. History Who invented the digital camera? This device was first created by Eastman Kodak engineer Steven Sasson in 1975. The camera used a solid state CCD image sensor chips manufactured by Fairchild Semiconductor. The device weighed 3.6 kilograms and it took above 20 seconds to capture an image. This camera was developed as a prototype and it is not intended for mass production. However, this device has the capacity to record black and white pictures. Additionally, the first digital camera has a resolution of 10,000 pixels or 0.01 megapixels. The first digital camera that was introduced to the public is the Fuji DS-1P, which was launched in 1988. The device has a 16 MB internal memory card and it has a battery. The device was not launched in Japan as well as in the United States. The next digital camera that was commercially available is the 1990 Dycam Model 1. It has a CCD image sensor and it can be connected to a computer or a laptop to transfer and store data. Eastman Kodak launched the first professional digital camera named as the Kodak DCS-100 in...
