The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. With each new generation‚ the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization‚ speed‚ power‚ and computer memory has proportionally increased

Lasers and Their Uses We have all at some point in our lives used or seen someone use a laser. They are used in compact disc players for stereos or computers‚ laser surgery‚ laser printers‚ holography‚ cutting and borring metals‚ communication‚ bar-code scanners‚ etc. Over the past three decades’ lasers have become a tool used daily by many people and they have become very useful in scientific research. As you can see lasers are a very useful and important tool which is why I have chosen this

Introduction: Samsung Electronics Company‚ henceforth called “Samsung” in this case‚ was established in 1969 to manufacture black-and-white TV sets. In 1974‚ Samsung‚ which was a producer of low-end consumer electronics‚ purchased Korea Semiconductor Company and began its semiconductor industry. Under the leadership of the chairman of Samsung Group‚ Kun He Lee‚ Samsung has risen‚ with a remarkable speed‚ to become the world’s leading memory producer‚ ranking 2nd just behind Intel. Meanwhile‚ Samsung used the

first recognized in 1839 by French physicist A. E. Becquerel. The photoelectric effect describes the release of positive and negative charge carriers in a solid state when light strikes its surface. Russell Ohl patented the modern junction semiconductor solar cell in 1946.Three scientists (Daryl Chapin‚ with Bell Labs colleagues Calvin Fuller and Gerald Pearson)invented the first practical device for converting sunlight into useful electrical power. This resulted in the production of the first

Samsung Group Timeline and History Samsung’s beginnings (1938 ~ 1969) On March 1‚ 1938‚ founding chairman Byung-Chull Lee started a business in Taegu‚ Korea with 30‚000 won. At first‚ Mr. Lee’s little business was primarily in trade export‚ selling dried Korean fish‚ vegetables‚ and fruit to Manchuria and Beijing. But in just over a decade‚ SAMSUNG - meaning literally "three stars" in Korean - would have its own flour mills and confectionery machines‚ its own manufacturing and sales operations

Fritts‚ who coated the semiconductor selenium with an extremely thin layer of gold to form the junctions. The device was only around 1% efficient. In 1888 Russian physicist Aleksandr Stoletov built the first photoelectric cell (based on the outer photoelectric effect discovered by Heinrich Hertz earlier in 1887). Albert Einstein explained the photoelectric effect in 1905 for which he received the Nobel prize in Physics in 1921.[2] Russell Ohl patented the modern junction semiconductor solar cell in 1946
