FLASH DRIVE

A USB flash drive is a NAND-type flash memory data storage device integrated with a USB (universal serial bus) interface. USB flash drives are typically removable and rewritable, much shorter than a floppy disk (1 to 4 inches or 2.5 to 10 cm), and weigh less than 2 ounces (60 g). Storage capacities typically range from 64 MB to 64 GB[1] with steady improvements in size and price per gigabyte. Some allow 1 million write or erase cycles[2][3] and have 10-year data retention,[4] connected by USB 1.1 or USB 2.0. USB Memory card readers are also available, whereby rather than being built-in, the memory is a removable flash memory card housed in what is otherwise a regular USB flash drive, as described below.
USB flash drives offer potential advantages over other portable storage devices, particularly the floppy disk. They are more compact, faster, hold much more data, have a more durable design, and are more reliable for lack of moving parts. Additionally, it has become increasingly common for computers to ship without floppy disk drives. USB ports, on the other hand, appear on almost every current mainstream PC and laptop. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Windows, Mac OS X, Linux, and other Unix-like systems. USB drives with USB 2.0 support can also be faster than an optical disc drive, while storing a larger amount of data in a much smaller space.
Nothing actually moves in a flash drive: it is called a drive because it is designed to read and write data using the same system commands as a mechanical disk drive, appearing to the computer operating system and user interface as just another drive.[3]
A flash drive consists of a small printed circuit board protected inside a plastic, metal, or rubberised case, robust enough to be carried with no additional protection, in a pocket or on a key chain for example. The USB connector is protected by a removable cap or by retracting into the body of the drive, although it is not liable to be damaged if exposed. Most flash drives use a standard type-A USB connection allowing them to be plugged into a port on a personal computer.
To access the drive it must be connected to a USB port, which powers the drive and allows it to send and receive data. Some flash drives, especially high-speed drives, may require more power than the limited amount provided by a bus-powered USB hub, such as those built into some computer keyboards or monitors. These drives will not work properly unless plugged directly into a host controller (i.e., the ports found on the computer itself) or a self-powered hub.

Chocolate

"Chocolates" redirects here. For other uses, see Chocolate (disambiguation).

Chocolate most commonly comes in dark, milk, and white varieties, with cocoa solids contributing to the brown coloration.
Chocolate (pronounced /ˈtʃɒklət/ (help·info) or /-ˈələt/) comprises a number of raw and processed foods that are produced from the seed of the tropical cacao tree. Native to lowland, tropical South America, cacao has been cultivated for at least three millennia in Central America and Mexico, with its earliest documented use around 1100 BC. The majority of the Mesoamerican peoples made chocolate beverages, including the Maya and Aztecs, who made it into a beverage known as xocolātl, a Nahuatl word meaning "bitter water". The seeds of the cacao tree have an intense bitter taste, and must be fermented to develop the flavor. After fermentation, the beans are dried, cleaned, and roasted, and the shell is removed to produce cacao nibs. The nibs are then ground and liquified, resulting in pure chocolate in fluid form: chocolate liquor. The liquor can be further processed into two components: cocoa solids and cocoa butter.
Pure, unsweetened chocolate contains primarily cocoa solids and cocoa butter in varying proportions. Much of the chocolate consumed today is in the form of sweet chocolate, combining chocolate with sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. "White chocolate" contains cocoa butter, sugar, and milk but no cocoa solids (and thus does not qualify to be considered true chocolate). Chocolate contains alkaloids such as theobromine and phenethylamine, which have some physiological effects in humans, but the presence of theobromine renders it toxic to some animals, such as dogs and cats.[1]. It has been linked to serotonin levels in the brain. Scientists claim that chocolate, eaten in moderation, can lower blood pressure.[2] Dark chocolate has recently been promoted for its health benefits, as it seems to possess substantial amount of antioxidants that reduce the formation of free radicals.
Chocolate has become one of the most popular flavors in the world. Gifts of chocolate molded into different shapes have become traditional on certain holidays: chocolate bunnies and eggs are popular on Easter, chocolate coins on Hanukkah, Santa Claus and other holiday symbols on Christmas, and hearts on Valentine's Day. Chocolate is also used in cold and hot beverages, to produce chocolate milk and hot chocolate.

Flag of thailand

The flag of Thailand shows five horizontal stripes in the colours red, white, blue, white and red, with the middle blue stripe being twice as wide as each of the other four. The three colours red-white-blue stand for nation-religion-king, an unofficial motto of Thailand.[citation needed] The flag was adopted on 28 September 1917, according to the royal decree about the flag in that year. The Thai name for the flag is ธงไตรรงค์ (Thong Trairong), which simply means tricolour flag.
The first flag used for Siam was probably a plain red one, first used under King Narai (1656-1688). Naval flags later used different symbols on the red ground—a white chakra (the weapon of god Vishnu which use as the symbol of the House of Chakri), or a white elephant inside the chakra.
Officially the first flag was created in 1855 by King Mongkut (Rama IV), showing a white elephant (a royal symbol) on red ground, as the plain coloured flag was not distinct enough for international relations.
In 1916 the flag was changed to the current design, but with the middle colour being the same red as the outer stripe. The story goes that during a flood King Vajiravudh (Rama VI) saw the flag hanging upside-down, and to prevent this from happening again created a new flag which was symmetrical. In 1917 the middle color was changed to dark blue, the auspicious colour for Saturday in Thai astrology, the day King Vajiravudh was born. According to other sources, the blue colour was also chosen to show solidarity with the Allies of World War I, which also had the colours blue-red-white in their flags.
The flag resembles the flag of Costa Rica, which was adopted 11 years prior to Thailand's. The main difference is that the blue and red colors are inverted.

The Royal Library of Alexandria

The Royal Library of Alexandria or Ancient Library of Alexandria in Alexandria, Egypt, was once the largest library in the ancient world. The Library of Alexandria, generally thought to have been founded at the beginning of the third century BC, was conceived and opened during the reign of Ptolemy I Soter, or that of his son Ptolemy II of Egypt. It has been reasonably established that the Library or parts of the collection were destroyed on a number of occasions, but to this day the details of the destruction (or destructions) remain a lively source of controversy based on inconclusive evidence. The Bibliotheca Alexandrina, an institution intended both as a commemoration and an emulation of the original, was inaugurated in 2003 near the site of the old Library
