A RISC -based computer architecture developed jointly by IBM, Apple Computer, and Motorola Corporation. The name is derived from IBM’s name for the architecture, Performance Optimization With Enhanced RISC.
The first computers based on the PowerPC architecture were the Power Macs, which appeared in 1994. Since then, other manufacturers, including IBM, have built PCs based on the PowerPC.
There are already a number of different operating systems that run on PowerPC-based computers, including the Macintosh operating system (System 7.5 and higher), Windows NT, and OS/2.
PowerPacket technology uses the same power line that provides electricity to your computer to network it to other computers in your home or office. PowerPacket uses Orthogonal Frequency Division Multiplexing (OFDM) to handle high-speed data transmission between computers. Electrical wires in a home are difficult to use for deploying a network as electrical wires are […]
- Power Usage Effectiveness
In Green IT, Power Usage Effectiveness (PUE) is a calculation used to determine energy efficiency measurements. PUE is calculated by measuring the ratio of total energy consumption-the combination of servers plus the cooling to “useful” energy consumption (just servers). PUE is a green computing tool being promoted by The Green Grid as a way to […]
- Pre-compilation Tool
In Web site development with ASP.NET, version 2.0 of ASP.NET includes an application deployment utility called the Pre-compilation Tool. Using this tool, Web developers are able to pre-compile a dynamic application prior to deployment and the Pre-compilation Tool will automatically identify any compilation issues anywhere within the site. The tool also lets ASP.NET applications to […]
- Pretty Good Privacy
(n.) Abbreviated as PGP, a technique developed by Philip Zimmerman for encrypting messages. PGP is one of the most common ways to protect messages on the Internet because it is effective, easy to use, and free. PGP is based on the public-key method, which uses two keys — one is a public key that you […]
- Print Screen key
Often abbreviated Prt Scr, the Print Screen key is a useful key supported on most PCs. In DOS, pressing the Print Screen key causes the computer to send whatever images and text are currently on the display screen to the printer. Some graphics programs, including Windows, use the Print Screen key to obtain screen captures.
