Down: 1) A touch screen is the only device which can be classed as both an input and an output device. It consists of a display monitor that is able to sense the location of a finger touching the screen. The location information is sent to the software currently running so that it can react to the event. For example, the screen may be showing a graphic image of a shopping cart. Touching the cart image with your finger may cause the software to open up a payment page.3) A computer keyboard is an input device that enables the user to enter characters (letters, numbers and symbols) into a computer. The keyboard consists of rows of keys with each key representing a different character. There are different types of keyboards available, for example, QWERTY keyboards, ergonomic keyboards, braille keyboards.6) This is what you call the working space you see on your monitor when the computer has booted up. You will see icons (shortcuts) on the screen to applications that you regularly used. You can also set up the background image to one that you like. Desktops are part of a graphical user interface.9) Data consists of numbers, words, sounds and images which have no meaning attached to them. For example 10082006. Once you are shown these same numbers in the format of 10/08/2006, you realise that they are a date, at which point they change from being data and become Information Across: 2) This is a small animal which is hunted by cats and snakes.4) A firewall is designed to help protect a computer network from intruders. It does this by controlling what data can and cannot pass through it. A firewall can either be A piece of software e.g. Windows has a built in Firewall, Zone Alarm is a free firewall or you can purchase commercial software firewalls. A piece of hardware. These boxes are much faster than the software version but they are also much more expensive and tricky to set up. You would expect home networks to be protected by a software firewall but a large corporation would have several layers of hardware firewalls protecting their networks as well as intruder detection software applications looking for odd behaviour on their networks. Basically, the more valuable or sensitive the information, the higher the level of protection expected.5) A compact disc or "CD" is a flat round disc used to store data. They are used to store music and other sounds (and sometimes called an "audio CD"). A standard CD-ROM can store up to 700 Mbytes of data. As a comparison a DVD can store about 4700 Mbytes of data. In order to use a CD-ROM, you need a CD-ROM drive or (now more commonly) a DVD drive that can also read the disk. CDs come in different formats: CD-ROM - Read Only Memory CD-RW - Read Write CD-R - Recordable Data is stored on the disk by 'burning' the disk. What actually happens is that a tiny laser beam burns a minute pit into the disk surface, each pit represnts a binary bit. The pits are burnt in a spiral as the disk spins around at high speed in the drive. A compact disc or "CD" is a flat round disc used to store data.

Its main role is to welcome you to the site, to give you an idea of what the site will contain and to provide links to other areas of the site so that you can navigate around. The home page is usually saved as index.html or index.htm8) Also called a 'combo-box'. A drop-down list usually has a small arrow on the right, that you click on to reveal a list of choices. You then make a choice, this closes the drop down list and makes you selection appear in the drop-down field. This is a very common software user interface element on forms (see also forms in the glossary). Drop-down lists are very useful when you want to limit that choice of what the user can select.10) Data consists of numbers, words, sounds and images which have no meaning attached to them. For example 10082006. Once you are shown these same numbers in the format of 10/08/2006, you realise that they are a date, at which point they change from being data and become Information
