Computer Features
The following features are standard to the computer's basic architecture.
AGP Video
An accelerated graphics port (AGP) video connector on the system board
and an AGP expansion card are standard features. AGP is a bus architecture
that increases video performance by routing video signals through a
dedicated graphics bus rather than sending video signals on the PCI bus.
BIOS
The basic input/output system (BIOS) is software that enables your
computer to communicate with peripheral devices (such as the keyboard,
mouse, and monitor) without using programs on the hard drive.
The battery in your computer maintains the BIOS settings in
complementary metal-oxide semiconductor (CMOS) memory even when
the computer is turned off.
You can change the BIOS settings through the Setup program. Open Setup
by pressing F1 when you are prompted as your computer starts.
Cache Memory
Your computer includes level 1 (L1) and level 2 (L2) cache. This cache
memory is located on the processor. Cache reduces the average time
required for the processor to get the data it needs from the main memory by
storing recently accessed data in the cache.
Connectors
The standard input/output (I/O) connectors included with the computer are:
•
Keyboard port
•
Mouse port
•
Two serial ports
