UTP Cable stands for Unshielded Twisted Pair cable. It doesn't provide electromagnetic interference from any electronics nearby the wiring, but is cheaper to buy than Foiled or Shielded Twisted Pair. Unless outside Electromagnetic Interference is more than a minor concern, I would suggest sticking to UTP. Also the most common used cabling in computer networking.
What else can I help you with?
Are there any switches which are powered by poe?
No, there are no switches that are powerd by POE. The POE uses one of the 4 pair in CAT cabeling so reasonably priced POE switches are slow 100Mb ps. POE switches use a LOT of power 8watts per port. Costs are coming down now. £400 for a 24 port GB switch like Netgear GS724P. But does no-one at all do a small say 4-port switch powered by PoE, of which I could use many, to extend the number of points in our school network without rewiring. Have just found that there are switches that are powered by PoE. Linksys SLM2005 and SLM2008 which are 5 and 8 port managed 10/100/1000 switches.
Pros and cons of cat6 cabeling?
Cat6 cable is very similar to Cat5e cable. It is, simply put, just held to a stricter standard than Cat5e cable. Since Cat6 is made to a higher standard than Cat5e it will support higher speed transfers. Cat5e cable can be used for networks up to a 1Gbps speed while Cat6 is currently rated for up to 10Gbps speed. Cat7 takes this even further and supports 40Gbps. For normal usage on networks up to 1Gbps and no run being longer than 100 meters, Cat5e is completely sufficient for the network. To ensure forwards compatibility it may be worthwhile to install Cat6 cable while you're at it so you don't hit a speed cap in your network down the road.
How is electricity distributed in houses in order to supply power to appliances?
Electricity get distributed in the household through electrical circuits. The circuits distribute voltage to receptacles, light and hard wired appliances. These circuits are fed from breakers that are in the distribution panel. The distribution panel is where the utility company's service supply terminates. The distribution panel is the central location where the household circuits originate.
How do you use 2 computers as one?
All you need to do is run out to CompUSA or go online and purchase a KVM switch. Basically, this will allow you to hook up a mouse, keyboard and monitor to two different machines. Most of the units have a button on the front which will switch from one system to the other, and in most cases you can just press the Ctrl+Alt keys to switch. Here is a link to the type I use (but I use mine to connect 4 systems, you'll only need the one that connects 2 systems). http://catalog.belkin.com/PureAV_detail.process?Merchant_Id=&Product_Id=134802 (this link is for a Belkin 2-Port KVM Switch with cabeling) Good Luck.
