2 BIOS
['baios] n. shkurtesë nga b asic i nput o utput s ystem ( BIOS) sistemi themelor për hyrje-dalje ( informatikë)What is BIOS?BIOS is an acronym for Basic Input/Output System. It is the boot firmware program on a PC, and controls the computer from the time you start it up until the operating system takes over. When you turn on a PC, the BIOS first conducts a basic hardware check, called a Power-On Self Test (POST), to determine whether all of the attachments are present and working. Then it loads the operating system into your computer's random access memory, or RAM.The BIOS also manages data flow between the computer's operating system and attached devices such as the hard disk, video card, keyboard, mouse, and printer.The BIOS stores the date, the time, and your system configuration information in a battery-powered, non-volatile memory chip, called a CMOS (Complementary Metal Oxide Semiconductor) after its manufacturing process.Although the BIOS is standardized and should rarely require updating, some older BIOS chips may not accommodate new hardware devices. Before the early 1990s, you couldn't update the BIOS without removing and replacing its ROM chip. Contemporary BIOS resides on memory chips such as flash chips or EEPROM (Electrically Erasable Programmable Read-Only Memory), so that you can update the BIOS yourself if necessary.For detailed information about BIOS updates, visit:What is firmware?Firmware consists of programs installed semi-permanently into memory, using various types of programmable ROM chips, such as PROMS, EPROMs, EEPROMs, and flash chips.Firmware is non-volatile, and will remain in memory after you turn the system off.Often, the term firmware is used to refer specifically to boot firmware, which controls a computer from the time that it is turned on until the primary operating system has taken over. Boot firmware's main function is to initialize the hardware and then to boot (load and execute) the primary operating system. On PCs, the boot firmware is usually referred to as the BIOS.What is the difference between memory and disk storage?Memory and disk storage both refer to internal storage space in a computer.The term memory usually means RAM (Random Access Memory). To refer to hard drive storage, the terms disk space or storage are usually used.Typically, computers have much less memory than disk space, because RAM is much more expensive per megabyte than a hard disk. Today, a typical desktop computer might come with 512MB of RAM, and a 40 gigabyte hard disk.Virtual memory is disk space that has been designated to act like RAM.Computers also contain a small amount of ROM, or read-only memory, containing permanent or semi-permanent (firmware) instructions for checking hardware and starting up the computer. On a PC, this is called the BIOS.What is RAM?RAM stands for Random Access Memory. RAM provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM.New computers typically come with at least 256 megabytes (MB) of RAM installed, and can be upgraded to 512MB or even a gigabyte or more.If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.RAM is volatile, so data stored in RAM stays there only as long as your computer is running. As soon as you turn the computer off, the data stored in RAM disappears.When you turn your computer on again, your computer's boot firmware (called BIOS on a PC) uses instructions stored semi-permanently in ROM chips to read your operating system and related files from the disk and load them back into RAM.Note: On a PC, different parts of RAM may be more or less easily accessible to programs. For example, cache RAM is made up of very high-speed RAM chips which sit between the CPU and main RAM, storing (i.e., caching) memory accesses by the CPU. Cache RAM helps to alleviate the gap between the speed of a CPU's megahertz rating and the ability of RAM to respond and deliver data. It reduces how often the CPU must wait for data from main memory.What is ROM?ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain.Almost every computer comes with a small amount of ROM containing the boot firmware. This consists of a few kilobytes of code that tell the computer what to do when it starts up, e.g., running hardware diagnostics and loading the operating system into RAM. On a PC, the boot firmware is called the BIOS.Originally, ROM was actually read-only. To update the programs in ROM, you had to remove and physically replace your ROM chips. Contemporary versions of ROM allow some limited rewriting, so you can usually upgrade firmware such as the BIOS by using installation software. Rewritable ROM chips include PROMs (programmable read-only memory), EPROMs (erasable read-only memory), EEPROMs (electrically erasable programmable read-only memory), and a common variation of EEPROMs called flash memory.What is an ACPI BIOS?ACPI is an acronym that stands for Advanced Configuration and Power Interface, a power management specification developed by Intel, Microsoft, and Toshiba. ACPI support is built into Windows 98 and later operating systems. ACPI is designed to allow the operating system to control the amount of power provided to each device or peripheral attached to the computer system. This provides much more stable and efficient power management and makes it possible for the operating system to turn off selected devices, such as a monitor or CD-ROM drive, when they are not in use.ACPI should help eliminate computer lockup on entering power saving or sleep mode. This will allow for improved power management, especially in portable computer systems where reducing power consumption is critical for extending battery life. ACPI also allows for the computer to be turned on and off by external devices, so that the touch of a mouse or the press of a key will "wake up" the computer. This new feature of ACPI, called OnNow, allows a computer to enter a sleep mode that uses very little power.In addition to providing power management, ACPI also evolves the existing Plug and Play BIOS (PnP BIOS) to make adding and configuring new hardware devices easier. This includes support for legacy non-PnP devices and improved support for combining older devices with ACPI hardware, allowing both to work in a more efficient manner in the same computer system. The end result of this is to make the BIOS more PnP compatible.What is CMOS?CMOS, short for Complementary Metal Oxide Semiconductor, is a low-power, low-heat semiconductor technology used in contemporary microchips, especially useful for battery-powered devices. The specific technology is explained in detail at:http://searchsmb.techtarget.com/sDefinition/0,,sid44_gci213860,00.htmlMost commonly, though, the term CMOS is used to refer to small battery-powered configuration chips on system boards of personal computers, where the BIOS stores the date, the time, and system configuration details.How do I enter the Setup program in my BIOS?Warning: Your BIOS Setup program is very powerful. An incorrect setting could cause your computer not to boot properly. You should make sure you understand what a setting does before you change it.You can usually run Setup by pressing a special function key or key combination soon after turning on the computer, during its power-on self test (POST), before the operating system loads (or before the operating system's splash screen shows). During POST, the BIOS usually displays a prompt such as:Press F2 to enter SetupMany newer computers display a brief screen, usually black and white, with the computer manufacturer's logo during POST.Entering the designated keystroke will take you into the BIOS Setup. Common keystrokes to enter the BIOS Setup are F1, F2, F10, and Del.On some computers, such as some Gateway or Compaq computers, graphics appear during the POST, and the BIOS information is hidden. You must press Esc to make these graphics disappear. Your monitor will then display the correct keystroke to enter.Note: If you press the key too early or too often, the BIOS may display an error message. To avoid this, wait about five seconds after turning the power on, and then press the key once or twice.What's the difference between BIOS and CMOS?Many people use the terms BIOS (basic input/output system) and CMOS (complementary metal oxide semiconductor) to refer to the same thing. Though they are related, they are distinct and separate components of a computer. The BIOS is the program that starts a computer up, and the CMOS is where the BIOS stores the date, time, and system configuration details it needs to start the computer.The BIOS is a small program that controls the computer from the time it powers on until the time the operating system takes over. The BIOS is firmware, which means it cannot store variable data.CMOS is a type of memory technology, but most people use the term to refer to the chip that stores variable data for startup. A computer's BIOS will initialize and control components like the floppy and hard drive controllers and the computer's hardware clock, but the specific parameters for startup and initializing components are stored in the CMOS. -
3 History of volleyball
________________________________________William G. Morgan (1870-1942) inventor of the game of volleyball________________________________________William G. Morgan (1870-1942), who was born in the State of New York, has gone down in history as the inventor of the game of volleyball, to which he originally gave the name "Mintonette".The young Morgan carried out his undergraduate studies at the Springfield College of the YMCA (Young Men's Christian Association) where he met James Naismith who, in 1891, had invented basketball. After graduating, Morgan spent his first year at the Auburn (Maine) YMCA after which, during the summer of 1896, he moved to the YMCA at Holyoke (Massachusetts) where he became Director of Physical Education. In this role he had the opportunity to establish, develop, and direct a vast programme of exercises and sports classes for male adults.His leadership was enthusiastically accepted, and his classes grew in numbers. He came to realise that he needed a certain type of competitive recreational game in order to vary his programme. Basketball, which sport was beginning to develop, seemed to suit young people, but it was necessary to find a less violent and less intense alternative for the older members.________________________________________________________________________________In 1995, the sport of Volleyball was 100 years old!The sport originated in the United States, and is now just achieving the type of popularity in the U.S. that it has received on a global basis, where it ranks behind only soccer among participation sports.Today there are more than 46 million Americans who play volleyball. There are 800 million players worldwide who play Volleyball at least once a week.In 1895, William G. Morgan, an instructor at the Young Men's Christian Association (YMCA) in Holyoke, Mass., decided to blend elements of basketball, baseball, tennis, and handball to create a game for his classes of businessmen which would demand less physical contact than basketball. He created the game of Volleyball (at that time called mintonette). Morgan borrowed the net from tennis, and raised it 6 feet 6 inches above the floor, just above the average man's head.During a demonstration game, someone remarked to Morgan that the players seemed to be volleying the ball back and forth over the net, and perhaps "volleyball" would be a more descriptive name for the sport.On July 7, 1896 at Springfield College the first game of "volleyball" was played.In 1900, a special ball was designed for the sport.1900 - YMCA spread volleyball to Canada, the Orient, and the Southern Hemisphere.1905 - YMCA spread volleyball to Cuba1907 Volleyball was presented at the Playground of America convention as one of the most popular sports1909 - YMCA spread volleyball to Puerto Rico1912 - YMCA spread volleyball to Uruguay1913 - Volleyball competition held in Far Eastern Games1917 - YMCA spread volleyball to BrazilIn 1916, in the Philippines, an offensive style of passing the ball in a high trajectory to be struck by another player (the set and spike) were introduced. The Filipinos developed the "bomba" or kill, and called the hitter a "bomberino".1916 - The NCAA was invited by the YMCA to aid in editing the rules and in promoting the sport. Volleyball was added to school and college physical education and intramural programs.In 1917, the game was changed from 21 to 15 points.1919 American Expeditionary Forces distributed 16,000 volleyballs to it's troops and allies. This provided a stimulus for the growth of volleyball in foreign lands.In 1920, three hits per side and back row attack rules were instituted.In 1922, the first YMCA national championships were held in Brooklyn, NY. 27 teams from 11 states were represented.In 1928, it became clear that tournaments and rules were needed, the United States Volleyball Association (USVBA, now USA Volleyball) was formed. The first U.S. Open was staged, as the field was open to non-YMCA squads.1930's Recreational sports programs became an important part of American lifeIn 1930, the first two-man beach game was played.In 1934, the approval and recognition of national volleyball referees.In 1937, at the AAU convention in Boston, action was taken to recognize the U.S. Volleyball Association as the official national governing body in the U.S.Late 1940s Forearm pass introduced to the game (as a desperation play) Most balls played with overhand pass1946 A study of recreation in the United States showed that volleyball ranked fifth among team sports being promoted and organizedIn 1947, the Federation Internationale De Volley-Ball (FIVB) was founded in Paris.In 1948, the first two-man beach tournament was held.In 1949, the first World Championships were held in Prague, Czechoslovakia.1949 USVBA added a collegiate division, for competitive college teams. For the first ten years collegiate competition was sparse. Teams formed only through the efforts of interested students and instructors. Many teams dissolved when the interested individuals left the college. Competitive teams were scattered, with no collegiate governing bodies providing leadership in the sport.1951 - Volleyball was played by over 50 million people each year in over 60 countries1955 - Pan American Games included volleyball1957 - The International Olympic Committee (IOC) designated volleyball as an Olympic team sport, to be included in the 1964 Olympic Games.1959 - International University Sports Federation (FISU) held the first University Games in Turin, Italy. Volleyball was one of the eight competitions held.1960 Seven midwestern institutions formed the Midwest Intercollegiate Volleyball Association (MIVA)1964Southern California Intercollegiate Volleyball Association (SCVIA) was formed in California1960's new techniques added to the game included - the soft spike (dink), forearm pass (bump), blocking across the net, and defensive diving and rolling.In 1964, Volleyball was introduced to the Olympic Games in Tokyo.The Japanese volleyball used in the 1964 Olympics, consisted of a rubber carcass with leather panelling. A similarly constructed ball is used in most modern competition.In 1965, the California Beach Volleyball Association (CBVA) was formed.1968 National Association of Intercollegiate Athletics (NAIA) made volleyball their fifteenth competitive sport.1969 The Executive Committee of the NCAA proposed addition of volleyball to its program.In 1974, the World Championships in Mexico were telecast in Japan.In 1975, the US National Women's team began a year-round training regime in Pasadena, Texas (moved to Colorado Springs in 1979, Coto de Caza and Fountain Valley, CA in 1980, and San Diego, CA in 1985).In 1977, the US National Men's team began a year-round training regime in Dayton, Ohio (moved to San Diego, CA in 1981).In 1983, the Association of Volleyball Professionals (AVP) was formed.In 1984, the US won their first medals at the Olympics in Los Angeles. The Men won the Gold, and the Women the Silver.In 1986, the Women's Professional Volleyball Association (WPVA) was formed.In 1987, the FIVB added a Beach Volleyball World Championship Series.In 1988, the US Men repeated the Gold in the Olympics in Korea.In 1989, the FIVB Sports Aid Program was created.In 1990, the World League was created.In 1992, the Four Person Pro Beach League was started in the United States.In 1994, Volleyball World Wide, created.In 1995, the sport of Volleyball was 100 years old!In 1996, 2-person beach volleyball was added to the OlympicsThere is a good book, "Volleyball Centennial: The First 100 Years", available on the history of the sport.________________________________________Copyright (c)Volleyball World WideVolleyball World Wide on the Computer Internet/WWWhttp://www.Volleyball.ORG/
