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 II® processor. With its advanced performance features, this MMX™ microprocessor supplies the speed and power you need to take advantage of even the most complex programs. In addition, the microprocessor incorporates new multimedia extensions into the Intel architecture, which 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) SDRAM (synchronous dynamic random access memory). L2 Cache L2 cache memory, which helps speed the exchange of information between the microprocessor and system memory, is integrated on the Pentium II processor in most models. 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 hard disk drive. 4 Using Your Personal Computer

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 II
processor.
With its advanced
performance features, this MMX
microprocessor supplies the speed and power you
need to take advantage of even the most complex programs.
In addition, the
microprocessor incorporates new multimedia extensions into the Intel architecture,
which 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)
SDRAM (synchronous dynamic random access memory).
L2 Cache
L2 cache memory, which helps speed the exchange of information between the
microprocessor and system memory, is integrated on the Pentium II processor in
most models.
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
