(adj.) (1) Describes an image in which individual pixels are apparent to the naked eye. Typically, the separate square pixels in bitmapped images such as GIFs do not appear individually. When the image is displayed too large or at a low resolution the image becomes pixelated (this is sometimes done purposely for special effect).
(2) Describes an image that has been converted from print to a digitized image, such as a GIF.
The term should not be confused with pixilated, which means whimsical and bemused.
- plain text
Refers to textual data in ASCII format. Plain text is the most portable format because it is supported by nearly every application on every machine. It is quite limited, however, because it cannot contain any formatting commands. In cryptography, plain text refers to any message that is not encrypted. Contrast with cipher text. Plain text […]
- plasma TV
Plasma TV’s create a picture from a gas (plasma) filled with xenon and neon atoms and millions of electrically charged atoms and electrons, that collide when you turn the power on. The energy the collision releases increases the energy level in the plasma and the neon and xenon release photons of light (similar to the […]
- plasma display
A type of flat-panel display that works by sandwiching a neon/xenon gas mixture between two sealed glass plates with parallel electrodes deposited on their surfaces. The plates are sealed so that the electrodes form right angles, creating pixels. When a voltage pulse passes between two electrodes, the gas breaks down and produces weakly ionized plasma, […]
The underlying hardware or software for a system. For example, the platform might be an Intel 80486 processor running DOS Version 6.0. The platform could also be UNIX machines on an Ethernet network. The platform defines a standard around which a system can be developed. Once the platform has been defined, software developers can produce […]
- platform security
A security model that is used to protect an entire platform and secures the entire span of software or devices on that platform, removing the need to incorporate individual or multiple security measures for different programs on the system. Security at the platform level makes the security process simplified for IT and developers. However, once […]
