Down: 1) A computer programming term. A translator converts a high level languagage such as C++ into machine code that the computer understands. The final file created is often called an 'object file' as it is a chunk of machine code - not neccessarily complete in itself. A number of object files may make up a complete computer program. A 'linker' will combine one or more 'object files' to form a complete 'executable' file that can be run on a computer.3) 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.4) These are an example of an 'output device'. Headphones may be connected to the computer's sound card so you can listen to a sound file. Some headphones also have a microphone attached so you can listen and speak.5) The Internet (or "The Net") is a computer network that connects computers worldwide. The Internet is made up of many smaller computer networks. These networks send and get messages using a standard Internet Protocol (IP). A protocol is like a language, that lets computers understand one another. The Internet is used for many things such as e-mail, online chat, news services, forums and the World Wide Web (WWW). The most used service on the Internet is the WWW which contains websites, web pages, blogs and wikis.7) 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. Across: 2) 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.6) The Internet (or "The Net") is a computer network that connects computers worldwide. The Internet is made up of many smaller computer networks. These networks send and get messages using a standard Internet Protocol (IP). A protocol is like a language, that lets computers understand one another. The Internet is used for many things such as e-mail, online chat, news services, forums and the World Wide Web (WWW). The most used service on the Internet is the WWW which contains websites, web pages, blogs and wikis.7) A social network8) 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.9) A keyboard is an 'input device' that has a set of electronic keys arranged in rows. A qwerty keyboard has letters of the alphabet on each button, numbers and also some other symbols such as brackets and comma. If you look at a normal keyboard, the first six keys on the top row spells out Q W E R T Y - hence how it got its name.
