World Book Day ( 23rd April 2012 )

World Book and Copyright Day (also known as International Day of the Book or World Book Days)

 is a yearly event on 23 April, organized by UNESCO to promote reading, publishing and copyright. The Day was first celebrated in 1995 and in 2012 the UK World Book day was celebrated on 1 March 2012.

World Book Day was celebrated for the first time on 23 April. The connection between 23 April and books was first made in 1923 by booksellers in Spain as a way to honor the author Miguel de Cervantes who died on that day.

        In 1995, UNESCO decided that the World Book and Copyright Day would be celebrated on this date because of the Catalonia festival and because the date is also the anniversary of the birth and death of William Shakespeare, the death of Miguel de Cervantes, Inca Garcilaso de la Vega and Josep Pla, and the birth of Maurice Druon, Manuel Mejía Vallejo and Halldór Laxness.

        Although 23 April is often stated as the anniversary of the deaths of both William Shakespeare and Miguel de Cervantes, this is not strictly correct. Cervantes died on 22 April and was buried on 23 April according the Gregorian calendar; however, at this time England still used the Julian calendar. Whilst Shakespeare died on 23 April by the Julian calendar in use in his own country at the time, he actually died eleven days after Cervantes because of the discrepancy between the two date systems. The apparent correspondence of the two dates was a fortunate coincidence for UNESCO. 

    In the  Spanish  region  of  Catalonia , on 23rd April , a rose  is  exchanged  for each  book  received 

Activity for IT students ( 12-04-2012 Thursday )

On last Thursday, all our IT students have a meeting at 2pm-4pm. Our agenda of meeting is about extra curriculur. Around 2pm-2:30pm we gather at Theater 2 at Level 4 with Mr.John & Mr.Gilbert. After and later we went to the ballet dancing room. Once we enter the ballet room we feel very warm and smelly.... Start of the program Ms.Carol have a warming up session with us. Later on Ms.Carol play funny games with us.. Such as playing jump to outer space, boat sinking and many more... 

Difference Between Multi‐core processor ，Dual‐core processor and Quad‐core processor

Multi‐core processor

A multi-core processor is a single computing component with two or more
independent actual processors (called "cores"), which are the units that read
and execute program instructions. The instructions are ordinary CPU
instructions such as add, move data, and branch, but the multiple cores can
run multiple instructions at the same time, increasing overall speed for
programs amenable to parallel computing. Manufacturers typically integrate
the cores onto a single integrated circuit die (known as a chip multiprocessor
or CMP), or onto multiple dies in a single chip package.

A many-core  processor is a multi-core processor in which the number of cores is large
enough that traditional multi-processor techniques are no longer
efficient[citation needed] — largely because of issues with congestion in
supplying instructions and data to the many processors. The many-core
threshold is roughly in the range of several tens of cores; above this threshold
network on chip technology is advantageous.

 Dual-core and Quad-core

A dual-core processor has two cores (e.g. AMD Phenom II X2, Intel Core Duo),
a quad-core processor contains four cores (e.g. AMD Phenom II X4, Intel's quadcore
processors, see i3, i5, and i7 at Intel Core)
