PCI (Peripheral Component Interconnect)
Developed by Intel, PCI is a local bus standard. A bus is a channel used to transfer
data to (input) and from (output) a computer and to or from a peripheral device. Most
PCs have a PCI bus usually implemented at 32-bits providing a 33 MHz clock speed
with a throughput rate of 133 MBps.
NetBurst® micro-architecture (Intel NetBurst® micro-architecture)
The NetBurst® micro-architecture delivers a number of new and innovative features
including Hyper Pipelined Technology, 400 MHz System Bus, Execution Trace
Cache, and Rapid Execution Engine. It also delivers a number of enhanced features,
including Advanced Transfer Cache, Advanced Dynamic Execution, Enhanced
Floating Point and Multimedia Unit, and Streaming SIMD Extensions 2. Intel
NetBurst® Microarchitecture provides higher throughput within the processor and out
to memory and I/O for improved headroom.
PCI
Peripheral Component Interface. It became apparent to manufacturers that the
8MHz AT ISA BUS on the standard PC was just not fast enough for today's
applications, and so PCI was invented. It is a high speed data bus that carries
information to and from components - known as 'Local Bus'.
PCI-X
The 64-bit PCI-X interface (PCI-X 1.0a) can be operated at 133 MHz, (or at 100 MHz
and 66 MHz) which achieves a greater than two-fold boost in performance over PCI
2.2 bus technology. The 133 MHz PCI-X interface achieves up to 1 GB/s throughput,
a two-fold increase over 66 MHz PCI 2.2.
PCI-Express
PCI Express is a 3rd generation I/O architecture where ISA and PCI were
respectively the 1st and 2nd generations. A high-speed, general-purpose serial I/O
interconnect, PCI Express will initially offers speeds of 2.5 Gigabits per second,
support multiple widths ("lanes" of data that range from 1 to 32), and scale to the
limits of copper. PCI Express will unify I/O architecture for desktop, mobile, server,
communications platforms, workstations and embedded devices while also
coexisting with PCI and USB connection types
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.
