Free Essays on Research Paper On Motherboards

Research Paper on Motherboards There are many types of motherboards ranging in size and shape. The first motherboard appeared in 1981 and was made by IBM PC. It measured 8† x 11.5† and had five expansion slots that were positioned 1† apart in the back, left of the board. The XT(Extended Technology) computer came about in 1982 and measured about 8.5† x 12† inches. This board had a total of eight expansion slots positioned at 0.8† apart. The first AT(Advanced Technology) board measured 12† x 13.5† and also had eight expansion slots spaced 0.8† apart. The popular form of the AT became the main model made by manufacturers. Mini At(8.7† x 18†) and Baby AT(8.57† x 13.04†) made it possible to put all of the components onto the board using less physical space. These designs made the mini-tower and mini-desktop form factor possible. The ATX(Advanced Technology Extended-style_ form factor was introduced in 1995 which made it easier for manufacturers to produce motherboard designs. The ATX had a maximum size of 12† x 9.6† and looked like a Baby AT board rotated 90 degrees. The board has a special design to accommodate the new, larger Pentium processors. Western Digital came up with the design for LPX(Low Profile Extended) motherboard in 1986 for corporate use. It made it possible to reduce space and costs, and soon lead to the creation of the slim-line â€Å"pizza box† style case which was meant to fit underneath a typical monitor. Expansion slots on the LPX style motherboard, were not built into the board itself, they were instead set on a riser card that plugged into the single slot connector on the motherboard. But there were a few problems with the LPX motherboards. There were only a few certain full-length I/O cards allowed for the board. Also, the installation of the I/O cards generated clutter while creating several temperature pockets that prevented good airflow through the system. Another problem was...

Context Clues and Literacy ESL Reading Lesson

Context Clues and Literacy ESL Reading Lesson One of the main challenges of any English reading skills class is that students tend to look up, or even insist on looking up, each word they do not understand. While this desire to understand everything is certainly laudable, it can be damaging in the long run. This is because students will begin to tire of reading if they are constantly interrupting the process to find another word in the dictionary. Of course, the use of e-readers might make this a little less bothersome. However, students need to realize that reading in English should be like reading in their own language. The use of contextual clues can be one of the best ways to improve students reading skills. Realizing that a text can be understood in a general sense by using contextual clues can go a long way towards helping students cope with increasingly difficult texts. At the same time, the use of contextual clues can also provide a means by which students can rapidly increase their existing vocabulary base. This lesson provides a number of pointers helping students identify and use context to their advantage. A worksheet is also included which helps students recognize and develop the skill of contextual understanding. Context Clues Reading Lesson Aim: Increased awareness and usage of contextual reading clues Activity: Awareness raising concerning the use of contextual clues, followed by worksheet practicing contextual reading Level: Intermediate - upper intermediate Outline Write this example sentence on the board: Tom decided that he desperately needed the glockum if he were to solve the problemAsk students what they do if they are reading an English text and do not understand a specific word.Ask students what they do if they are reading a text in their native language and do not understand a specific word.Ask students what glockum means.Once students have established that they dont know what a glockum is, ask them to guess at what it might be.Ask students what part of speech a glockum is (i.e. verb, noun, preposition etc.)Have students explain how they arrived at their guesses, which clues did they use?Explain the concept of reading in chunks i.e. looking at the text surrounding the unknown word for clues.Show them an article from an advanced level magazine (Wired, National Geographic, The Economist etc.)Ask students to identify the probable vocabulary areas that may be used in the example article.Explain the importance of activating vocabulary by fir st quickly glancing at the text to be read. This idea is very important as the brain will begin to focus on related concepts thus preparing the student for what is to be read. Point out that by using all of these clues (i.e. chunking, part of speech, logical deduction, vocabulary activation), students can arrive at a much fuller understanding of difficult texts - even if they do not understand each wordHave students divide into small groups and complete worksheet. Reading Clues Deduction - What does the sentence concern? Which words does the unknown word seem to relate to?   Part of Speech - Which part of speech is the unknown word? Is it a verb, noun, preposition, adjective, time expression or something else? Chunking - What do the words around the unknown word(s) mean? How could the unknown word(s) relate to those words? - This is basically deduction on a more local level. Vocabulary Activation - When quickly skimming through the text, what does the text seem to concern? Does the layout (design) of the text give any clues? Does the publication or type of book give any clues to what the text might be about? Which words can you think of that belong to this vocabulary category? Make logical guesses about the meaning of the unknown words in the following paragraph. Jack quickly entered the didot and cleaned the various misturaes he had been using to repair the wuipit. He had often thought that this job was extremely yullning. However, he had to admit that this time things seemed to be a bit easier. When he finished, he put on his redick and went back to the study to relax. He took out his favourite pipe and settled into the beautiful new pogtry. What a fantastic schnappy he had made when he had bought the pogtry. Only 300 yagmas! What could a didot be? What part of speech is misturaes? If Jack used the misturaes to repair the wuipit what do you think the mistraes must be? What could yulling mean? - What part of speech is often used with an ending -ing ? Which synonym could be used for yulling ? fundifficultexpensive What type of things do you put on? Based on the above question, what kind of thing must a redick be? Is a pogtry used inside or outside? Which words let you know that the pogtry was cheap? What must yagmas be? ClothesCigarette typeType of money
