GIF - The GIF image format is widely used on the World Wide Web. It was initially used by Compuserve to compress images for display on its online services. GIF uses a loss-less compression algorithm based on LZW. LZW is patented in some countries. A new standard, PNG, uses similar, non-patented compression algorithm and supports a wider range of image types including full colour images. PNG is well supported in recent software.
Guerrilla marketing - Unconventional marketing programs designed to get maximum results out of minimal resources. Guerilla marketing by definition means making an investment in marketing with your time, energy, and imagination rather than merely your money. Coined by Jay Conrad Levinson, guerilla marketing is more about matching wits than matching budgets. Popular with the SOHO market, online tactics include newsletters, making use of e-mail lists, making appropriate newsgroup postings, sending out multiple press release announcements, establishing a dynamic Web site, submitting to the search engines, posting content such as product reviews, getting your business listed in all the appropriate places, and so on (as opposed to buying superbowl ads or investing in ad banners).
GUI - A Graphical User Interface (GUI) is a computer interface which consists of visual controls such as menus, buttons and windows. The alternative to a GUI is a console or command-line interface, where the user must type commands as text rather than using visual controls such as menus and buttons. A GUI is widely regarded as easier to use, but it is much more complicated to create.
