OSP
Open Source Portfolio (OSP) is a robust, non-proprietary, open-source electronic portfolio application, developed by a community of individuals and organisations from around the world.
The OSPortfolio provides an environment where portfolio owners — typically, students — can exhibit their work.
- tools to collect items that best represent their accomplishments, their learning, or their work;
- tools to reflect upon these items and their connections;
- tools to design a portfolio that showcases the best selections of this work;
- and tools to publish the portfolio to designated audiences.
OPEN SOURCE
Open source software is a licensing model for software which gives free access to the source code of the software to allow interested parties to modify or contribute to the software as they see fit. Commonly created as collaborative projects and shared at no cost.
OUT OF GAMUT
The phrase “out of gamut” refers to a range of colours that cannot be reproduced within the CMYK colour space used for commercial printing. Graphics software is designed to work with images in the RGB colour space throughout the editing process. The RGB colour space has a much wider range of discernible colours than CMYK. When you print an image it must be reproduced with inks and these inks cannot reproduce the same range of colours that we can see with our eyes. Because the gamut of colour that can be reproduced with ink is much smaller than what we can see, any colour that cannot be reproduced with ink is referred to as “out of gamut.” In graphics software, you often will see an out of gamut warning when you select colours that will shift when an image is converted from the RGB colour space used in the editing process, to the CMYK space used for commercial printing.
OPACITY
Refers to being “opaque,” which means to prevent light from shining through. For example, in an image editing program, the opacity level for some function might range from completely transparent (0) to completely opaque (100).
PHOTOSHOP
A raster-based professional image-editing, manipulation and graphic creating software program from Adobe.
PDA (PERSONAL DIGITAL ASSISTANT)
PDA is a term for any small mobile hand-held device that provides computing and information storage and retrieval capabilities for personal or business use, often for keeping schedule calendars and address book information handy.
PORTAL
A portal consists of web pages that act as a starting point for using the Web or web-based services. The word was first used to describe the sites of popular Internet access providers or search engines such as AOL, MSN and Yahoo! Later on, it was extended into the world of work, where a corporate portal or enterprise information portal acts as a starting point for employees or associates of an organization to access corporate information and applications. Portal software has become a distinct class of web server software that acts as a platform for deploying portals.
PATH (FILE/FOLDER PATH)
Files/ folder are identified by a sequence of symbols and names. Every file has a name (filename). The simplest type of pathname is a filename. If a filename is specified as a pathname, the operating system looks for that file in your current working directory. However, if the file resides in a different directory, you must tell the operating system how to find that directory. You do this by specifying a path that the operating system must follow. The pathname always starts from your working directory or from the root directory. Each operating system has its own rules for specifying paths. In DOS systems, the root directory is named \, and each subdirectory is separated by an additional backslash. In UNIX, the root directory is named /, and each subdirectory is followed by a slash. In Mac environments, directories are separated by a colon.
The location of the file as it is stored in a series of directories
PLUG IN
Software modules that add specific features or services to a larger program or system.
PODCAST
A podcast is a series of digital media files which are distributed over the internet using syndication feeds for playback on portable media players and computers. The term podcast, like broadcast, can refer either to the series of content itself or to the method by which it is syndicated; the latter is also called podcasting. The host orauthor of a podcast is often called a podcaster.

PIXEL
A pixel (picture element) is a single point n a graphic image. Graphics monitors display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are so close together that they appear connected. The number of bits used to represent each pixel determines how many colors or shades of gray can be displayed. For example, in 8-bit color mode, the color monitor uses 8 bits for each pixel, making it possible to display 2 to the 8th power (256) different colors or shades of gray.
On color monitors, each pixel is actually composed of three dots — a red, a blue, and a green one. Ideally, the three dots should all converge at the same point, but all monitors have some convergence error that can make color pixels appear fuzzy.
The quality of a display system largely depends on its resolution, how many pixels it can display, and how many bits are used to represent each pixel. VGA systems display 640 by 480, or about 300,000 pixels. In contrast, SVGA systems display 800 by 600, or 480,000 pixels. True Color systems use 24 bits per pixel, allowing them to display more than 16 million different colors.
A digital picture is made of three fields of color intensity measurements, and a pixel is the mixture of red, green, and blue intensities at a location in the picture
PNG FILE
A compressed graphics file format which creates a smaller file size by only remembering a limited number of colors for use in the image.
PIXELLATED
Describes an image in which individual pixels are apparent to the naked eye. Typically, the separate square pixels in bitmapped images such as GÏFs do not appear individually. When the image is displayed too large or at a low resloution the image becomes pixelated (this is sometimes done purposely for special effect).
Top image (original) Bottom image (pixelated)
PDF FILE
Portable Document Format, the cross-platform document format created by Adobe’s Acrobat application. Commonly used to capture, distribute, and store electronic documents, PDF preserves the fonts, images, graphics, and overall “look” of the original digital files. As with the GIF format, the PDF format is proprietary, although widely used. Files in PDF end with a .pdf extension.
PROXY SERVER
A server which caches information on a network to speed up acess for users by sending local copies of content instead of copies from remote servers.
AUDIO MP3
MPEG Audio Layer 3, an audio compression technology developed in Germany in 1991.
