PRAM

Stands for "Parameter Random Access Memory". PRAM is a type of memory found in Macintosh computers that stores system settings. These settings include display settings (like screen resolution and color depth), the time zone setting, speaker volume, and the startup volume choice. The system settings that are stored in the computer's PRAM differ from Mac to Mac, but the purpose of the memory remains the same. If your Macintosh is behaving erratically or is not booting up all the way, you may want to try resetting the PRAM.

Memory Bandwidth

Generally, bandwidth refers to data-carrying capacity and is expressed in cycles per second or Hertz (Hz). In the case of RAM, bandwidth is a function of its rated speed and the size of its data path.

Green Book

Green Book is the compact disc standard created by Sony and Philips to work on CD-I players. Like most other CD-playing hardware, CD-I players can play back audio CDs (something both Sony and Philips have a vested interest in, since Sony sells CDs, and Philips sells CD-I players). But no other CD-playing platform can make use of Green Book CDs.
