Down: 1) 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.2) 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) Pagination is the process of breaking up the contents in a document into seperate pages.5) Some software, such as the spreadsheet application Excel, can pull data out of a web page and load it as a table in the application. A 'web query' is set up so that it points to the web page containing the data - once it is set up a link is established with the web page and the query is carried out to extract the data. In Excel, you will find Web Query in the 'Get External Data' under the 'Data' menu7) Spam means sending massive amounts of electronic junk mail that people haven't asked for. In legal terms it means to send 'unsolicited commercial email' This term is used because the vast majority of spam is sent in order to try and persuade you to buy something. Many ISP email packages offer 'spam filters' that try to prevent these emails getting through to your inbox, but it is a very difficult problem to separate spam from wanted emails. Your email service may have a 'Bulk' or 'Junk' box that contain the diverted spam. It is then up to you to have a look to see if there are some real emails accidentaly caught by the filters. To give you an idea of the problem, it is estimated that around 80%-90% of all emails on the internet is spam.8) A computer programming term. This is the name given to a "defined set of steps that can be used to complete a task". For example there are 'algorithms' worked out for sorting a list efficiently. A computer programmer can buy a book of algorithms so they not need to re-invent the wheel when they have to code for a job that has already been worked out. Having bought the book, they would look up the problem of 'How to sort a list' and a good book would tell them a number of ways to do this. Note: Algorithms are not computer code, so a programmer using 'C++' can use the same algorithm as someone programming in 'Java', they use the same steps, just coded differently.10) 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.12) LCD is a type of display used in many portable computers. LCD works by two sheets of polarizing material with a liquid crystal surface sandwiched in between. An electric current is passed through the liquid, causing the crystals to turn dark. A light source is passed through the crystals creating the display on the screen.14) 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: 4) A 'cable' is a physical method of moving data and signals from one place to another. it is made up of one or more lengths of wires, sheathed in some form of protective cladding. The cable will have a connector at either end to join the two systems together. There are many types of cable, made from many different materials. Each type of cable is designed with a task in mind. For example 'Mains Cable' is designed to carry electrical power. 'Network cable' is designed to carry data around a network. 'Satellite cable' and 'Co-axial' cable is designed to carry radio signals. 'Fibre-Optic' cable is designed to carry light signals and is made of glass and plastic. Cables are designed to only work over a certain distance, because all cables, if long enough, will eventually absorb the signal they are meant to carry. For example it is reasonable to use network cable over a few hundred metres, maybe even a few kilometres, but you would not expect it to work when stretched from one city to another.6) Bits per second (BPS) is a measurement of the rate at which data is carried or sent over a network connection. It is normally expressed in thousands - Kilobits per second (Kbps) or millions, Megabits per second (Mbps).9) computer networking term. To 'Log On' means you need to identify yourself to the system so that you can gain access. The most common way of logging on is to provide an username and password that the system recognises. The most common way of failing to log on is to forget your password and / or username.11) A thumbnail is a small version of an image. It allows you to view the image without having to open it, which if it is a large file, could take time. The thumbnail is linked to the larger image, so if you click on it, the larger image will automatically open. Thumbnails are useful when you want to quickly view a large number of images which are available.13) 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.15) Gigabyte is a measurement of computer memory capacity. It is equivalent to 1024 Megabytes although you will commonly see it referred to as 1,000 Megabytes (which isn't correct).
