What Your IBM Personal Computer Offers
This section describes many of the features of your computer.
Microprocessor
At the core of your PC is an Intel

Pentium

processor or an Intel Pentium
processor with MMX

technology. With its advanced performance features, the
microprocessor supplies the speed and power you need to take advantage of even
the most complex programs. In addition, the microprocessor with MMX technology
incorporates new multimedia extensions into the Intel architecture. MMX
technology improves the performance of multimedia and communications
applications by accelerating calculations commonly performed for audio, video,
speech synthesis and recognition, 2D and 3D graphics, and data communications.
System Memory
Your computer comes standard with non-parity or ECC (error correcting code) EDO
(extended data out) DRAM (dynamic random access memory). EDO uses advanced
technology to increase system performance.
L2 Cache
L2 cache memory, which helps speed the exchange of information between the
microprocessor and system memory, is integrated on the system board in your PC.
ISA Bus
Your PC has an ISA (industry standard architecture) bus, which is one of the most
widely used and successful I/O (input/output) buses available. The ISA bus is
popular because so many adapters and devices have been designed and marketed
for it.
PCI Bus
Your computer also has a PCI (peripheral component interconnect) bus. PCI is one
of the advanced I/O bus standards recently developed by the computer industry to
keep up with performance improvements of microprocessor buses and advanced
peripheral devices. The PCI bus adds to the capability of the ISA bus, speeding up
the exchange of information among the microprocessor and peripheral devices
within your computer system. This improves the overall performance of your
computer, including the video and the hard disk drive.
