(IMP.) Hardware - Frequently Asked Questions :

1.) Windows explorer is not working , what might be the problem and how you will fix?

If The successful login is not letting the administrator to enter into the starting screen , then there will be missing of the browseui.dll,that file should be reinstalled to get the windows explorer working back.

2.) What are the components with which the Cisco Aironet components can associate?

Not 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.

3.) What are the different platforms of Cisco Aironet APs available?

Cisco Aironet 1500 Series
Cisco Aironet 1300 Series
Cisco Aironet 1240 AG Series
Cisco Aironet 1230 AG Series
Cisco Aironet 1200 Series
Cisco Aironet 1130 AG Series
Cisco Aironet 1100 Series
Cisco Aironet 1000 Series

4.) WHAT MACS ARE UPGRADEABLE TO THE POWERPC?

Apple 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.

5.) CAN I ADD AN FPU TO MY MAC? CAN I REPLACE THE 68LC040 WITH A 68040?

All 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.

6.) WHAT'S VRAM?

Video 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.

7.) What is Exchange Server 2007?

Exchange 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 solution.

8.) What does it mean to "power cycle" a device?

Power 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.

9.) What does it mean when a computer is "low on resources?"

The 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.

Best Of Luck..
