D is for...Dongle, Download, Desktop and DOS Attack

Dongle: A dongle is an amusingly named device that connects computers to the internet via wireless broadband. Dongles can be used as software protection devices, providing a layer of security to prevent theft of licensed software.

Download: Downloading is the transfer of data, software or other information from the internet or a remote system to a personal computer or nearby device. It also describes the action of transferring data from a larger to a smaller computer, or from a computer to a mobile or peripheral device. A download is a file that can be or has been transferred.

Desktop: The meaning of desktop in computing is twofold. Firstly, it can be the background image of a display screen, on which windows, icons and other graphical items appear. Secondly, it can describe a desktop computer - a non-portable device that sits, literally, on your desktop. Simple!

Denial of Service (DOS) Attack: A DOS attack is a malicious attack on a Web server designed to interrupt, inconvenience or curtail that server’s normal operation. A DOS attack usually takes the form of the co-ordination of thousands of client computers all trying to interact with the server simultaneously. The server can not cope with the sudden rush of traffic and thus fails. DOS attacks are often achieved through the use of botnets.
