Computer-Aided Control Technology
The story of computer-aided control technology is inextricably entwined with the modern history of automation. Automation in the first half of the twentieth century involved (often analog) processes for continuous automatic measurement and control of hardware by hydraulic, mechanical, or electromechanical means. These processes facilitated the development and refinement of battlefield fire-control systems, feedback amplifiers for use in telephony, electrical grid simulators, numerically controlled milling machines, and dozens of other innovations.

Arkadaşımın tanıdığı için bir web sitesi yaptım. Site bir dedektiflik sitesi . Çok sade bir site istediler. Ben de html ve css kullanarak biraz da hazır kodlardan faydalanarak 2 günde basit bir site yaptım. Sitenin adı :

İnternet IP adreslerinin IPv6′ya geçecek olması neden önemli, bu standarta neden ihtiyacımız var? İşte bunun cevapları IPv4 adreslerin tükenmesiyle birlikte önem kazanıyor.
Gelecek yıl bu zamanlarda IPv4 IP adreslerinin tükeneceği tahmin ediliyor. İnternetin ilk günlerinde bugünlerin geleceği tahmin edilememişti.
Internet Protocol Number oluşturulduğunda bunun amacı veri paketlerinin doğru adrese ulaştırılmasıydı.
IP protokol sürüm IPv4 , 4,294,967,296 adresi destekleyebiliyor. Alt ağlara ve hostlara yayılan bu IP adresleri tükenmek üzere. IPv6 ise 3.400.000.000.000.000.000.000.000.000.000.000.000.000 adresi destekleyebiliyor. Bu sayı yeryüzündeki herkese yetecek kadar IP adresi verebiliyor.

Just as on the high street, online retailers need to advertise to grab attention, and this process can help match consumers to products. However, businesses should not mislead consumers for example by applying false or misleading descriptions, or by advertising prices that do not correspond to the actual prices charged.
Poor information provision by retailers can undermine competition and affect consumer behaviour. It makes it hard for consumers to compare final prices when searching online, and complicates their decision-making by requiring them to click through to additional pages or even register with a site to find the final price. In other words, it increases their ‘search costs’. It can also lead them to buy products with conditions and restrictions on them that they were unaware of. In the worst instances, consumers may actually find that they have paid more than they thought they had.

Optical materials were essential for many of the twentieth century’s most significant technological accomplishments. Humans have been intrigued with the development of optical materials and light behavior for centuries. Thomas Alva Edison, Max Planck, Albert Einstein, Max Born, and Niels Bohr presented significant optical theories and innovations that provided a foundation for research, development, and application of twentieth century optical materials. Significant optical milestones included the introduction of lens coating in the 1930s and lasers in 1960; fiber optics emerged by mid-century, and thousands of scientists innovated and adapted uses for optical materials in the following decades. Engineers established the International Society for Optical Engineering (SPIE) in 1955 to coordinate Professional efforts. Devamını Oku »
Before the Internet was created, the U.S. military had developed and deployed communications networks, including a network known as ARPANET. Uses of the networks were restricted to military personnel and the researchers who developed the technology. Many people regard the ARPANET as the precursor of the Internet. From the 1970s until the late 1980s the Internet was a U.S. government-funded communication and research tool restricted almost exclusively to academic and military uses. It was administered by the National Science Foundation (NSF). At universities, only a handful of researchers working on Internet research had access. In the 1980s the NSF developed an “acceptable use policy” that relaxed restrictions and allowed faculty at universities to use the Internet for research and scholarly activities. However, the NSF policy prohibited all commercial uses of the Internet. Under this policy advertising did not appear on the Internet, and people could not charge for access to Internet content or sell products or services on the Internet.

A byproduct of the development of radar during World War II, the microwave oven is now a common part of the modern kitchen. The microwave oven uses high-frequency radio waves generated by a magnetron tube to heat food by molecular friction. To put it another way, it causes the water molecules in the food to vibrate vigorously, and this vibration creates heat. Unlike conventional methods of cooking, where food is cooked from the outside in, the microwave oven cooks from the inside out. The high-frequency waves penetrate to the interior of the food. This results in considerably shorter preparation times than for other means of cooking. A culinary shortcoming, however, is that the microwave oven cannot ordinarily make foods, notably meats, brown and crisp.
