What is multihead graphics card?
A multihead graphics or video card is a card that plugs into the motherboard of a computer and supports more than one monitor or display device. This can be either of:
- The card has multiple connectors, each for a standard monitor cable connecting to a different monitor.
- The card has a single connector for a special cable that splits into several cables that can connect to monitors.
The disappearance of the volume icon on the Windows XP taskbar could mean the computer is infected by a virus. It may also be as a result of a corruption of registry settings.
What is the maximum length for BNC cable?
The BNC (Bayonet Neill Concelman) connectoris a very common type of RF connector used for terminating coaxial cable.
There is no predetemined maximum length for the coax cable. The maximum length of cable is going to be governed by determining the input signal level, the minimum output signal level, and the signal loss based on the length of the cable between the input and minimum output.
Can a folder contain other folders?
Yes. You simply make a folder, then open it, then right click, then left click "New", then left click "Folder." Done. That easy. Or if you have an old one button mouse click on your folder and click new---> new folder.
Does a PC already have a graphics card installed?
Most computers come with an Integrated Video Chipset, which means yes it's pre-installed. If you buy a new motherboard, it may not come with Integrated graphics, but it will have either a VGA or PCI-E slot to add an external one. Then again, if a motherboard had integrated graphics it also may still have a VGA or PCI-E slot to upgrade.
Is Central processing unit a part of a computer's hardware or a software program?
Both, the software sends most of the info to the CPU to be "processed" where it is routed and may return to be processed and routed a number of times before it is processed to a logical conclusion ( through Boolean logic) otherwise a loop occurs with no logical conclusion and mayhem occurs.
Why is your microphone so quiet?
Most microphones have a volume dial on them. If a microphone is too quiet, try turning up the volume. If this does not work, make sure you are close enough to the micophone and speaking directly into it.
What are the FRU components on newer motherboards?
FRU is an acronym of "Field Replicable Unit". It indicates a component of a computer system that can be replaced by a field service technician on a customer site. The contrasts with "CRU" or "Customer Replaceable Unit" which does not require a field service tech to perform the replacement.
FRU naming and access are defined in the IPMI (Intelligent Platform Management Interface) specification maintained by Intel Corporation here:
http://www.intel.com/design/servers/ipmi/spec.htm
FRU information is most often accessible using the IPMI protocol either via the IPMI drivers on a running computer or through a Service Processor.
These are the most common FRU devices.
- CPUs
- RAM modules
- System drives, such as floppy, hard drives, and optical drives
- Bus devices, such as video cards and sound cards
- Power supply units
- Cooling fans
- Peripherals, such as keyboards, mice, printers, and the cables connecting them
You can try "Safe-Mode".
What is a magnetic card reader?
A magnetic card reader is a device which reads information contained in a encrypted sequence on a magnetic strip. Such as a credit card reader, or Driverse License reader. Hotel Door locks now commonly have a magnetic card reader attached to replace the old fassioned key, since the cards are so cheap to make, and can be remade even if the original is lost.

How do you bypass isp with wireless g plus router?
The ISP is what gives your router its internet connection. You can't bypass the ISP any more than you can bypass the power utility company in getting electricity - you can switch provider or "borrow" from your neighbour, but you need to get it from somewhere.

Does Ethernet transmit signals in digital form or analog form?
HDMI is a digital replacement for existing analog video standards, such as 3D, an Ethernet data connection and improved audio and video capacity.
How do you control hardware in C?
Platform-dependent. If you have an OS on your computer, then most likely you cannot access hardware directly from userland programs.
Why does your computer shut down when you dont tell it to shut down?
Could be because of overheating - some motherboards have cutoffs when it reaches a certain temperature
Simply adding an extra fan could solve the problem Could be because of overheating - some motherboards have cutoffs when it reaches a certain temperature
Simply adding an extra fan could solve the problem
What is the BIOS setup needed for?
The BIOS setup program is used for many different things:
1. All of the slots, connections, voltages, and peripherals of your computer are managed by your BIOS. The motherboard requires the BIOS to boot, or even power on.
2. The setup window (usually accessible by hitting "delete" or "F1/F2" during boot) is used to manage all items mentioned in 1. On high end motherboards, you can change RAM (memory) clock speeds, CPU clock speeds, CPU and RAM voltages (very dangerous) and many other aspects of the hardware as well. This is how you "Overclock" your computer.
Most retail computers "HP" "Dell" etc... don't allow you to change anything in the BIOS to help them "idiot proof" their products.
