Tools for remotely managing servers are available from many sources. Some of the tools are specific to a task, while others support a range of tasks. Some provide a command-line environment, while others provide a graphical user interface (GUI) environment. Some tools work best for managing a single computer at a time, while others support sessions with multiple computers.

How to setup two monitors with two separate graphics cards on one computer?

First, you have to have an SLI ready motherboard, got that, so far so good. Then you need 2 SLI ready graphics cards (use nvidia for graphics cards and motherboard for this), You got that, then connect the 2 graphics cards in the mother board, then connect them together using the bridge it comes with in every box for an SLI ready card. Then get your dual monitors and connect on to one graphics card then connect the other monitor to the other card. The bridge that connects the 2 graphics cards together makes the cards join together as if one big one. Hoping everything works out.

The purpose of a crossover cable is to supply the output of one computer as the input to another. As such the most certainly can share their resources. This is done to:

  • connecting two devices directly, output of one to input of the other without an intervening network connection
  • letting two terminal (DTE) devices communicate without an interconnecting hub knot
  • linking two or more hubs, switches, or routers together, possibly to work as one wider device.

Which components use the front-side bus?

The Front-Side Bus lies between the CPU and the Northbridge chipset.

The Northbridge chipset controls the highspeed devices on the motherboard such as PCI components, Memory, and AGP Video, however the Northbridge needs a direct communication link to the CPU in order to when to send data to control these devices. That's where the FSB comes into play and provides that direct link. One wishing to overclock their system must take into the speed of the Northbridge chipset as it plays an important part in determining Overclocking speeds.

However, on some computers, you need to go to a menu during the boot sequence (on my computer, I need to press F12) to boot from mediums other than the primary hard disk.
