Flash Memory
Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR gate, NOR and NAND gate, NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level, depending on whether the state of the bit line or word lines is pulled high or low; in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire devi ...

Laptop
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a Clamshell design, clamshell form factor (design), form factor with a flat-panel computer screen, screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is in the lower part, under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for PC game, playing games, Content creation, content creating, web browser, web browsing, for personal multimedia, and for general P ...

Tanaka Hisashige
was a Japanese businessman, inventor, mechanical engineer, and rangaku scholar who was prominent during the Bakumatsu and early Meiji period in Japan. In 1875, he founded what became the Toshiba Corporation. He has been called the "Thomas Edison of Japan" or "Karakuri Giemon." Biography Tanaka was born in Kurume, Chikugo province (present-day Fukuoka prefecture) as the eldest son of a tortoise shell craftsman. Apprenticed at an early age, he was a gifted artisan. At the age of eight, he invented an inkstone case with a secret lock, which required a cord to be twisted in a certain manner to open it. At the age of 14, he had invented a loom capable of weaving intricate designs into fabric. From age 20 he began to make ''karakuri'' puppet dolls, autonomous dolls powered by springs, pneumatics and hydraulics, capable of relatively complex movements, which were much in demand by the aristocrats of Kyoto, ''daimyō'' in feudal domains, and by the Shōgun's court in Edo.

Shibaura Seisakusho
was the new name given to the company Tanaka Seisakusho (Tanaka Engineering Works), after it was declared insolvent in 1893 and taken over by Mitsui Bank. In 1910 it formed a tie-up with General Electric (GE) which in exchange for technology acquired about a quarter of the shares of Shibaura. With this investment GE now had a stake in both Tokyo Denki and Shibaura Seisakusho - two companies that had a complementary line of products in light as well as heavy electrical equipment. Both companies were merged in 1939 to create Tokyo Shibaura Denki (Tokyo Shibaura Electric Company, now Toshiba). The relation with GE continued until the beginning of the war and, after the war, resumed in 1953 with GE's 24 percent shareholding. This percentage has however decreased substantially since then.

Hakunetsusha
was a company established by Shōichi Miyoshi and Fujioka Ichisuke, two of Japan's industrial pioneers during the Tokugawa / Edo period. It specialized in the manufacturing of light bulbs. The company was established in 1890, and started out by selling bulbs using bamboo filaments. However, following the opening up of trade with the West through the Unequal treaty, Hakunetsusha met with fierce competition from imports. Its bulb cost about 60 per cent more than the imports and the quality was poorer. The company managed to survive with the booms after the First Sino-Japanese War of 1894–95 and the Russo-Japanese War of 1904–05, but afterward its financial position was precarious. In 1905 the company was renamed Tokyo Denki (Tokyo Electric) and entered into a financial and technological collaboration with General Electric of USA. General Electric acquired 51 percent share of ownership, sent a vice president, and provided the technology for bulb-making. Production equipment w ...

Quantum Cryptography
Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution, which offers an information-theoretically secure solution to the key exchange problem. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical (i.e. non-quantum) communication. For example, it is impossible to copy data encoded in a quantum state. If one attempts to read the encoded data, the quantum state will be changed due to wave function collapse ( no-cloning theorem). This could be used to detect eavesdropping in quantum key distribution (QKD). History In the early 1970s, Stephen Wiesner, then at Columbia University in New York, introduced the concept of quantum conjugate coding. His seminal paper titled "Conjugate Coding" was rejected by the IEEE Informa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure.
