  1. A computer system consists of hardware and software.

    Under the mouse is a ball, which rolls as the mouse is moved. This movement of he ball causes two shafts to rotate inside the mouse; one shaft records the movement in the north-south direction and the other shaft records the east-west movement. When the screen pointer is over a0n icon or menu selection, the mouse button can be clicked, double clicked or dragged to activate a process. Some mice have a small wheel as well as the buttons. The function of the wheel depends on the software being used on the computer; in a document, it can allow the

The keyboard also contains certain standard function keys, such as the Escape key, tab and cursor movement keys, shift and control keys, and sometimes other manufacturer-customized keys. QWERTY Keyboard A standard keyboard named after the first six letters in the top row. This keyboard was actually designed to slow down typists who kept jamming the early mechanical typewriters. Now everyone still uses the less-efficient QWERTY keyboards because, as the saying goes, it is hard to teach an old dog new tricks.

  6. What is hardware?

    The standard mouse comprises casing, buttons and base. As technology has developed, the mouse has evolved from its original design and now come in different styles to suit different requirements. Scanner This is an input device that reads words or graphics from a printed page and translates the pattern of light and dark (or colour) into a digital signal the computer can store and manipulate. The most common scanner is the flatbed scanner that works quite like a photocopier. Hand-held scanners are still used but, as flat board scanners are now quite inexpensive, their use is diminishing.

  8. Mr Fitzpatrick has taught me rugby in the past and he likes to keep his players fit.

    Alternative solutions discussed The fitness plan could be typed out on Microsoft word and handed to all the players as a document to read, but this would take more time than required and would also cost money in paper and ink. This sheet could also be lost before the player has read it meaning that it has served no purpose because the player has not read it. The plan could also be done on Microsoft excel as a spreadsheet but again as with word that will take up too much time and cost money in ink and paper.

  10. How do the land use, housing and environmental quality in Tudor, Callowland, Nascot and Park wards of Watford affect the relative "desirability" of the wards?

    For example, a student would not live in a 5 bedroom detached house. PARK WARD This was the first ward visited and due to the fact that this was the first time I had visited these wards, this ward has left an indentation in my mind of my first impression of Watford. We commenced north up Hempstead road and took a left into Stratford way, where our fieldwork began. Small detached housing covered this area. The field sketch below shows you how close the house's boundaries are, as well as the style and age of the houses.

  11. I intend to produce a piece of software to enable young children to establish the basic computer skills as a foundation to there IT learning - I shall do this by having two separate learning games, Mouse Movement and Keyboard Skills.

    The user should type the word in the text box provided, and then click "OK". Here we are reinforcing the previous exercise to allow the user to practise. In both activities, if the user enters the word correctly, clapping will sound, again for the psychological reason that if the child is being praised they are encouraged to repeat the event again and the next colour/word will appear. On the other hand if the user gets it wrong, TRY AGAIN will appear, three incorrect answers and the task will be completed for then in slow motion to allow then to learn from there mistakes.

  12. Hard Drive Technology

    But today, most platters are made from material like glass or ceramic composite. These light, strong materials have a very low thermal expansion, and compare to aluminum. They can withstand higher forces. So the platters can run faster. Older hard disk drive can only run at 3600 to 5200 rpm. Today's ones can run 7600 to 10000 rpm. There is a layer of magnetic material on the surface of the platters. Today a thin-film media is used here. Thin-film media is a microscopic layer of pure metal bonded to the substrate surface through an interim layer.

  15. Desktop Publishing - Skating Brochure

    I could use page plus, Coral Draw, Paint or Microsoft Publisher these are all very good desktop publishing programs. I could use Microsoft Paint but there is no word art/ Clip art and other very useful features it is also very difficult to edit when it is there and is just not very easy to use.

  16. Tesco Report: "One Team Around The World"

    The makers of this document would have use large monitors so they could see the whole thing at once. A colour laser printer would have been used so to produce high quality colour print outs quickly. A mouse, keyboard and processor would have also been used. The document uses tables charts and graphs to show information easily. Design guides have been used to make it satisfying to the eye and easy to make sense of the information. To frame the text large margins have been used. For what it is trying to say, it is very good at it.

    into the motherboard to keep costs down. It will need to contain several different types of ports. There will need to be around 4 USB ports (for various peripherals, e.g. digital camera, scanner, printer), a parallel port (for the printer or scanner), two PS2 ports (one each for the keyboard and mouse), and a serial port (some digital cameras still connect his way). This will give them a choice of connection options and extra peripherals. A modem will be needed to connect to the Internet.

  19. My advice to David and Angela is to buy a package first of all, a desktop package, which will allow them to do various tasks for their club. So after searching on the web I have decided they should buy a package.

    It has also got 256 DDR RAM, which I feel is a spacious area. It will allow the computer to do various tasks at one time so that could be useful. The next good area of this computer package is that it holds a 40GB hard drive. This huge hard drive will certainly enable David and Angela to save there work on it and also produce a lot of documents and also save them. It will also enable them to load new packages such as a graphics package, which could design the logo's etc because 40 GB is a huge space.

  20. To create the new Top Toggs information system I have used a computer of the following specification:

    Therefore when a key is pressed it triggers an electronic signal that the computer interprets as a binary number, which is in turn changed into the appropriate character. The mouse is a device allowing a pointer to be moved around the screen in response to the relative position to the mouse. Two optical sensors monitor two wheels, at 90 degrees to each other (equivalent to the y and x axis on a graph) driven by a spherical mouse ball. These optical signals which are read as a set of co-ordinates to be able to plot the mouse pointer on the screen.
