RAM
Random Access Memory - the memory used by the computer for running programs
and storing data.
ROM
Read Only Memory - a memory chip which doesn't lose its data when the system is
switched off. It is used to store the System BIOS and VGA BIOS instructions. It is
slower than RAM.
Rapid Execution Engine
Part of the Pentium® 4 processor's Intel® NetBurst® micro-architecture. Two
Arithmetic Logic Units (ALUs) are clocked at twice the core processor frequency,
allowing basic integer instructions such as Add, Subtract, Logical AND, and Logical
OR to execute in half of a clock cycle. For example, the Rapid Execution Engine on
a 1.50 GHz Pentium 4 processor runs at 3 GHz.
S-ATA (Serial ATA)
Serial ATA is the next-generation internal storage interconnect designed to replace
Parallel ATA technology. Serial ATA is the proactive evolution of the ATA interface
from a parallel bus to a serial bus architecture. This architecture overcomes many
design and usage constraints that are increasing the difficulty of continued speed
enhancements for the classic parallel ATA bus. Serial ATA will be introduced at
150Mbytes/sec, with a roadmap already planned through 600Mbytes/sec.
Shadow Memory
The BIOS is normally stored in ROM. On certain systems it can be copied to RAM on
power up to make it go faster. This RAM is known as shadow memory. The System
BIOS is responsible for this copying.
SSE (Streaming SIMD Extensions)
Internet Streaming SIMD (Single Instruction Multiple Data) Extensions are
instructions that reduce the overall number of instructions required to execute a
particular program task. As a result, they can boost performance by accelerating a
broad range of applications, including video, speech, and image, photo processing,
encryption, financial, engineering and scientific applications. NetBurst® micro-
architecture adds 144 new SSE instructions, which are known as SSE2.
Streaming SIMD Extensions 3
Better multimedia and encryption/decryption processing than previous generations,
along with support for more computationally intensive graphics.
Super VGA
Additional screen modes and capabilities provided over and above the standard
VGA defined by IBM.
VGA
Video Graphics Array - the graphics standard defined by IBM and provided on IBM's
PS/2 machines.
