Most modern PCs also come with external cache memory, called Level 2 (L2) caches. These caches sit between the CPU and the DRAM. Like L1 caches, L2 caches are composed of SRAM but they are much larger. Disk caching works under the same principle as memory caching, but instead of using high- speed SRAM, a disk cache uses conventional main memory. The most recently accessed data from the disk (as well as adjacent sectors) is stored in a memory buffer. When a program needs to access data from the disk, it first checks the disk cache to see if the data is there. Disk caching can dramatically improve the performance of applications, because accessing a byte of data in RAM can be thousands of times faster than accessing a byte on a hard disk. When data is found in the cache, it is called a cache hit, and the effectiveness of a cache is judged by its hit rate. Many cache systems use a technique known as smart caching, in which

.....................................................................................................8-9 Conclusion.........................................................................................................................10 2 Introduction This chapter documents the advent and rise of automated essay scoring (AES) as a means of both assessment and instruction. The first section discusses what AES is, how it works, and who the major purveyors of the technology are. The second section describes outgrowths of the technology as it applies to on-going projects in measurement and education. In 1973, the late Ellis Page and colleagues at the University of Connecticut programmed the first successful automated essay scoring engine, "Project Essay Grade (PEG)" (1973). The technology was foretold some six years earlier in a landmark Phi
social activities. The National Union of Students was founded in 1922. It operates through local branches in colleges and universities. It promotes the educational, social and general interests of students. But certainly the most numerous is the Scout Association, founded in 1908 for boys and in 1910 for girls by Lord Baden-Powel. The Scout movement is to encourage a sense of adventure and of responsibility for others among young people. The programme of training is planned to develop intelligence and practical skills, to promote health and a sense of service. Scout training is complementary to the ordinary education. Scouts train in mapping, signalling, first aid and all the skills that arise from camping and similar outdoor activities. British scouts take part in international scout meetings, which are held approximately every four years. The membership in this or that youth organization is not compulsory in Great Britain.

The impact in society the emergence of the camera was important and shocking because it helped us capture important moments in time that can no longer be repeated and helped a lot in the field of communication. The first models of cameras were used in the years before Christ where they were used to see closely objects. After its emergence was marked a before and after in history because thanks to this artefact can capture exact moments in which a event happened. Advancing in history have improved the types of cameras, passing cameras that took several minutes to take a photograph so far in which the process of taking a photograph or several is instantaneous. In addition, the cameras allow us to keep

The greatest writer of this period and the whole of medieval times Geoffrey Chaucer (1340?-1400): · The father of English poetry · The creator of English versification · The first poet to use various metres · Laid the foundation of the new literary English language · Wrote in Middle English · An active man of affairs, who belonged to the middle class · Spoke Latin, French, Italian the important languages of the time · Worked as a diplomat for a time · Translated works into English (from Latin, French, Italian) · Favourite of the royal court · At the time of his death was regarded as a great poet and was buried in Westminster
THE ANGLO-SAXON PERIOD English literature came when the Angles, the Saxons, the Jutes and the Frisians invaded Britain. During this time English was called Anglo- Saxon or Old English. In the chronicles of Roman history (composed in Latin) is said that Britain makes its first appearance in written language when Romans invade the England. BEOWULF most important poem, surviving in a 10th-cent manuscript. The historical period of the poem's events can be dated in the 6th to 8th century. Much of the material of the poem is legendary and paralleled in other Germanic historical-mythological literature in Norse, Old English, and German.

I grew up in Pittsburgh and went to college at Cornell, so I can answer for both. The weather is terrible, particularly in winter, and there's no interesting old city to make up for it, as there is in Boston. Rich people don't want to live in Pittsburgh or Ithaca. So while there are plenty of hackers who could start startups, there's no one to invest in them. Not Bureaucrats Do you really need the rich people? Wouldn't it work to have the government invest in the nerds? No, it would not. Startup investors are a distinct type of rich people. They tend to have a lot of experience themselves in the technology business. This helps them pick the right startups, and means they can supply advice and connections as well as money. And the fact that they have a personal stake in the outcome makes them really pay attention. Bureaucrats by their nature are the exact opposite sort of people from startup investors.
My languages I love different languages. I mean, I really, really love different languages. I also believe and have been told that I pick them up rather easily. That might be true, although I did not pick any Greek up in Greece but that might have been because they spoke so damn fast that I could not tell if it was a word or an entire sentence. The first foreign language I learned was Russian. Considering I was ten when Estonia became a Republic, it makes sense. We began studying Russian in first grade, though it was simplified – "koška" instead of "kot", "medvešonok" instead of "medved", "saichik" etc. Did not make much sense and we mostly played some games in Russian (Tare-tareke etc). Learned as much playing outside, since we had Estonian-Russian kids around as well. Not that we played with them. It's sad
The language is being used about half a million people in Wales and possibly another few hundred thousand people within England and even Australia and United States of America. The normal language of every day life is still English but in some regions such as Gwynedd and Dyfed, the use of Welsh is very wide and well spread. The tendency nowadays is towards the development and introduction of Welsh. This could not have been said at the first part of the 20th century. Welsh have been under the reign or a part of Great Britain for a long time. During the 16 th century, particularly at the time of Henry the VIII, they tried to force the Welsh language out by an Act which declared that the language to be used in courts and administrative offices would have to be English. And of course the most natural process started as people were forced to talk English, they taught their children English and the Welsh language was to be forgotten

SUMMARY........................................................... 10 11. SOURCES.............................................................. 11 INTRODUCTION The Mysterious Affair at Styles is a detective novel by Agatha Christie. It was written in 1916 and was first published by John Lane in the USA in October 1920 and in the UK by The Bodley Head (John Lane's UK company) on January 21 1921. In her first novel, The Mysterious Affair at Styles(1920), she created the now-famous Belgian detective Hercule Poirot, the most popular sleuth in fiction since Sherlock Holmes. Poirot and Marple have also been portrayed in the many films, radio programmes and stage plays based on her books
"Kui ta läks männipuust maalimislaua juurde, mis asetses kõrge kardinatega kaetud akna all, tõstis Dorian Gray kuldse pea patjadelt ning vaatas teda kahvatu näoga ja pisarais silmadega." (Chapter 2, p. 25) I think this book is worth recommending to everybody. Every person can find something amusive and learn from Dorian's mistakes. Conclusion Overall, I think this book was quite an enjoyable reading. Altough, at first it was a little bit dull and too Dorian-centered, the plot developed nicely and became more interesting.
BOOK REPORT Title of the book: Fight Club Author (name and some general information): Chuck Palahniuk is an American novelist born February 21, 1962 in Washington, USA. He is best known as the author for the novel Fight Club (1996), which was made into a movie in 1999. Palahniuk began writing fiction in his mid-thirties. When he attempted to publish his novel, Invisible Monsters, publishers rejected it for its disturbing content. This led him to work on Fight Club which he wrote as an attempt to disturb the publisher even more for rejecting him. After initially publishing it as a short story in the 1995 compilation, Pursuit of Happiness, Palahniuk expanded it into a full novel, which --contrary to his expectations--the publisher was willing to publish. Some other well-known novels: Rant, Choke, Diary. Analysis of the book 1. Setting The story takes place in somewhere between 1980s and 1990s in the United States. 2

Law (see Crystal 1987). In languages with widespread literacy, other means of forming new words are based on the writing system. In English both abbreviations (e.g. BBC, MP, PC, etc.) and acronyms (e.g. radar) are common. (Radar stands for RAdio Detection And Ranging.) Other languages use other devices (for example, in languages that use the Chinese writing system, it is common for long compounds to be reduced to the first elements of the subcompounds they contain, so that Japanese too-kyo dai-gakku `Tokyo University', literally `east-capital big-school' is usually referred to as too-dai literally `east-big' but more idiomatically translated as something like `TU'). German abbreviations/acronyms are often based not on the first letter of the component words, but on the letters for the onset and nucleus of the first syllable of the component words, e.g. Gestapo from GEheimSTAatsPOlizei `secret state police'.
How to Write a Design Report Summary A design report is the written record of the project and generally is the only record that lives once the design team disbands at the end of the project. The report has three sections. The first section describes the problem that was being solved and provides the background to the design. The second section describes the design and the third section evaluates how well the design worked by comparing its performance to the design requirements. The report starts with a short executive summary that contains a synopsis of the three sections. The body of the report is relatively short. Appendices to the
