IEEE 1394 (also known as firewire), Hi-Speed USB 2.0, and SCSI
SATA (Serial ATA) is a type of interface. It's a format of cable and socket that connects hard drives and optical drives to the motherboard. The main purpose of SATA was to provide a faster interface to hard drives to replace the aging ATA interface. It also uses much thinner cables which help with cable routing and airflow. Pretty much every new consumer hard drive uses some form of SATA to connect to the motherboard.
a soundcard is a component on the computer that generaly handles the sound, instead of using the standard motherboard output 3.5mm jacks. a audio interface is a general term for the interface of (fermware, software, other programs) and such that play digital music files... why dont you google "How does a computer work?" you might learn sompthing :D
Both are vital components of your computer without a motherboard their would be no possible way to run your computer since it like the "brain" of the computer. Without a CPU, your computer would not be able to process anything, it might not even start up.
You might be able to solve a problem with a notebook that has an unstable system or a motherboard component by?
A school might use a scanner for security purposes (weapons), or to search for electronics that are not allowed.
Because you might drop the drives on your motherboard while installing.
Please check whether you installed proper driver for your scanner.
Without knowing what particular motherboard model you have, there is no way of answering that. The board might support higher, it might be maxed out, or the processor might even be soldered on! THIS IS ALL WRONG!! YO MAMA~!
It depends on the motherboard, and built-in devices. You might have to change the sound card, or the display adapter
The Xpress 1150 is an integrated graphics chip, meaning part of the motherboard. While you can't upgrade it, it might be possible to incorporate a third party videocard.
Perhaps, because there might be not enough place after you install the motherboard to install your drives. The CPU or the RAMs might be in they way. There is surely no other magical reason to it.
If you mean: how reliable is the information you hear on a police scanner, then fairly so, though it's possible the people are relaying untruthful information given to them by an unreliable third party or reporting their (possibly mistaken) impressions and observations of the moment. It's also just barely possible that someone might actually intentionally lie ("He shot first."). If you mean: if a police scanner says the frequency is umpty-ump point whatever megahertz, how likely is it to actually be that: pretty darn dependable, unless you've got some sort of cheap crummy scanner.
