... on the LGA-775 processor socket
A few systems are using a new Intel CPU.
The new LGA-775 processor socket is technically configured so
that the contact between the socket (pins) and the CPU (contact
points) can be made with adjacent contact pins.
Caution! Conventional 478pin processors may not be used. If
the current processor is to be changed to a 775pin
processor, this must be done very carefully, if possible
by technically qualified personnel.
2.3 The working memory
For the internal exchange of data, the PC requires somewhere to
temporarily store information. This is done in the working memory,
also called the main memory. The working memory can be
accessed very quickly and at any time. However, its content is lost
when the power is turned off.

The slots for expansion cards are located on the motherboard.
There are the following slots:
for modems
AMR (Audio Modem Riser)
CNR (Communication Network Riser)
for graphics cards
AGP (Accelerated Graphics Port) In the near future these slots
will be replaced by
PCI (Peripheral Component Interconnect) Express X16
