Eric H. Glendinning and John McEwanO2006. Oxford English for Information Technology. 2nd ed. OUP. 12 UNIT 2 Computer Architecture LANGUAGE WORK We can describe the function of an item in a number of ways. Study these examples. Using the Present simple 1 ROM holds instructions which are needed to start up the computer. Used to-infinitive, Used for + -ing form 2 ROM is used ro hold instructions which are needed to start up the computer. 3 ROM is used for holding instructions which are needed to start up the computer Emphasising the function 4 The function of ROM is to hold instructions which are needed to start up the computer. —I Match each item in Column A with its Function in Column B. Then describe its function in two ways. A Item B Function RAM controls the cursor processor inputs data through keys like a typewriter mouse displays the output from a computer on a clock screen flash memory key reads DVD-ROMs monitor reads and writes to electronic chips on a card keyboard holds instructions which are needed to DVD-ROM drive start up the computer cache holds data read or written to it by the ROM processor provides extremely fast access for sections of a program and its data controls the timing of signals in the computer controls all the operations in a computer UNIT 2 Computer Architecture 13 With the help of the Glossary if necessary, describe the functions of these items. 1 scanner 6 supercomputer 2 printer 7 mainframe computer 3 ATM 8 barcodes k PDA 9 swipe cards 5 hard disk drive 10 memory LANGUAGE WORK Prepositions of place and l idy these examples of prepositions of place.

She's advising Give, the Sales Director. Listen to Part 1 of the recording to find the answers to these questions: 1 What is Give's problem? 2 What does he want to do? 70 unit 10 Computing Support Officer LANGUAGE WORK Study these uses of //-sentences. Action and effect We can use an //-sentence to link an action and its effect. For example: 1 If you click on that; eh - - , that'll just compact your C drive fk 2 If you click on that »cti« , that opens it up and shows you all your folders The action is in the Present simple and the effect is in the Present simple or described using will, can, or may depending how certain it is to follow. Polite instructions We use the action part of //-sentences, especially in spoken English, to give instructions in a polite way.The effect part is assumed. 3 If you bring your cursor down to the very bottom [you'll find the Start button]. 4 If you just hit Enter [that will activate the program]. Imagined action and effect We can use an //-sentence to describe the possible effect of an imagined action. For example: 5 If you spilled coffee on your keyboard , you could damage it 6 If there were no other folders there , you wouldn't have a little box in there I possible effect'. To show this describes imagined, not real, events, the action is in the Past simple and the effect is described using would, could, and might depending how certain it is to follow. Match the actions in Column A with appropriate effects from Column B. Then join each action and effect using an //-sentence. Column A Column B you press Print Screen a you can drag it across the screen 2 you press Ctrl + Alt + Del in Windows b it would speed up the computer XP c you may lose data 3 you added more memory d you would have more space at your desk 4 you installed a modem e you would be able to connect to a 5 you used a better search engine telephone line 6 you forget to save regularly f you can make a copy of the screen 7 you hold down the mouse button over g you would find more relevant results an icon h it displays the Windows security 8 you used an LCD display dialog box UNIT 10 Computing Support Officer 71 « Describe the effects of these actions using an //-sentence. 1 you don't virus-check floppies 2 there was a power cut while you were using your computer 3 you install a faster processor A you forgot your password 5 you press the delete key 6 you use a search engine 7 you double-click on an icon 8 you use power-saving options [J| Noun + Noun compounds Match each word from Column A with its partner from Column B to make a computing term.

UNIT 17 Computing Support 119 Diagnose these faults and provide advice on each problem. 1 My laser printer produces very faint copies. 2 When I print, three or four sheets come through the printer at the same time. 3 My spreadsheet does not seem to add up correctly. A Everything I type appears in capitals. 5 My PC is switched on but the monitor screen is blank. 6 I tried to print a document but nothing came out of the printer. 7 My monitor picture is too narrow. 8 My monitor screen flickers. 9 My mouse responds erratically. 10 The time display on my computer is one hour slow. 11 When I print out a page, the first two lines are missing. 12 My computer sometimes stops and reboots itself. The lights dim at the same time. PROBLEM-SOLVING | As a class, find out how many had problems with any of these items of hardware in the last twelve months.
