What are the components with which the Cisco Aironet components can associate?
all Aironet devices can associate with all other types of Aironet devices. For
instance, the Client Adapter card cannot form a wireless association with a
Workgroup Bridge (WGB). Refer to Cisco Aironet Hardware Association Matrix for a
complete description of association capabilities.

WHAT MACS ARE UPGRADEABLE TO THE POWERPC?
will provide logic board replacements for all Centris, Quadra and WorkGroup
Server models except the Quadra 700,900 and 950. There should also be logic
board replacements for the IIvx, IIvi, LC 475, 520, 550, and 575, Performa
475,476, 550, and 600. Upgraded AV Macs will lose their special video
capabilities, at least initially. Apple will also make available PowerPC
processor upgrade boards that fit into the PDS slots of the Quadra 605, 610,
650, 700, 800, 900, and 950 as well as the Centris 610 and 650 and the Performa
475 and 476. Macs upgraded via a PDS card run at twice the speed of the system
clock. Thus a 25 MHz 68040 Mac with a PDS accelerator will become a 50 MHz
PowerMac. You'll be able to disable the accelerator if you have old software
that's not PowerPC compatible or that just plain runs faster on the older
hardware. 68030 desktop Macs with expansion slots will be upgradeable via third
party accelerator cards. Daughtercard upgrades for the Powerbook 500 and Duo 280
series will be available sometime late this summer or early fall.
CAN I ADD AN FPU TO MY MAC? CAN I REPLACE THE 68LC040 WITH A 68040?
68020 and 68030 desktop Macs that did not ship with an FPU standard (i.e. the
IIsi and LC series) have special slots that can accommodate an FPU card. All
Macs that have the FPUless 680LC40 CPU run just fine if that chip is replaced
with a full 68040 that includes an FPU. All PowerPC Macs include an integrated
FPU. There is no way to add only an FPU to a 68000 Mac like an SE though some
third party accelerators do include FPU's as well as faster CPU's.
RAM is where the computer stores the images displayed on your screen. On some
earlier Macs with built-in video (Mac 128, IIci) this was kept in main memory.
However it's considerably more efficient and faster to store the screen image in
its own separate RAM. Generally the more VRAM you have the more colors or shades
of gray you can display and the larger the monitors you can use. The chart below
shows the number of colors that can be displayed at a given resolution with the
specified amount of VRAM.
What is Exchange Server 2007?
Server 2007 is the next version of Exchange Server, the industry's leading
server for e-mail, calendaring, and unified messaging. The release of Exchange
Server 2007 is closely aligned with the Microsoft Office 2007 wave of products,
which together deliver a best-in-class enterprise messaging and collaboration
What does it mean to "power cycle" a device?
cycling an electronic device is a technical way of saying "resetting"
it. When you power cycle a device, you turn it off and then turn it back on
again. Pretty high-tech, huh? Usually, you should let the device sit for a
couple seconds after turning it off to make sure the memory in the device is
fully cleared before turning it back on. Any electronic device can be power
cycled, but the term is frequently used with cable modems, DSL modems, and
routers. This is because small internal errors in these devices can prevent them
from functioning correctly. Resetting them typically fixes the errors and allows
them to work correctly again.
What does it mean when a computer is "low on resources?"
resources a computer has are mainly processing speed, hard disk storage, and
memory. The phrase "low on resources" usually means the computer is
running out of memory. The best way to prevent this error from coming up is to
install more RAM on your machine. Upgrading your RAM is the best performance
booster you can give your computer, and it usually doesn't cost a lot.
