Understanding Wireless

Wireless is a connection between a device with other devices without using cables.Wireless Personal Area Network PAN is connected to the wireless media. Wireless technology used in this PAN is IrDA and Bluetooth.Wireless LAN is connected via a computer network without wires. Local Area Network of computers and other devices that communicate via radio signals or light waves. This system is useful when connecting via cable or fiber optic connection is quite expensive, or to move the connection application. Data communication technology with no cables to connect between the client and server. Wireless LAN technology in general is similar to a computer network technology that uses a cable (Wire LAN or Local Area Networks). Wireless LAN technology is using radio frequency to send and receive data that would reduce the need for or dependency relationships through cable. As a result, users have high mobility or flexibility and not dependent on a place or location. Wireless LAN technology is also possible to form a network of computers that may not be accessible by computer networks that use a cable.Wireless Card is a card that is used to support the computer can be connected in a network. These cards

How to Make an RJ45 UTP Cable (Straight & Cross)

This time I repost from blogger friends who happened to be I want to know how to create / organize cables and RJ45 Straight Cable & Cross Order to be made ​​on a computer network terbuhung online to the internet / local. Than useful for me and you also want to learn to make their own lan network cable. Just follow the steps - steps below.

Before starting, of course we have to have a :

•      crimping pliers
•      UTP cable
•      RJ-45 connector
•      Cable Tester 
  
  
  Crimping pliers
  
  
  Tang krimping is a tool to cut UTP cable, and to clamp the end of the connector, and this is very
  

The difference between UTP cable with STP cable

Differences UTP cable with STP cable.

Differences in STP cables with UTP cable is if the STP cable with a protective aluminum diselaputi, whereas UTP cable is not. whether the use of aluminum on the membranes that cover the STP cable? . The point is to avoid the radiation field around the magnet on the cable. but the price of kebel STP is more expensive than UTP cable. how the composition of the cord? . same as the existing arrangement on UTP cable.

Cable types in the Network

Various Kinds Network Cable
The cable is one of the media for data transmission network, which is used to connect one computer to other computers, send the information to function in the form of electrical signals between the network computer. network cables are used there are 4 kinds:

1. Coaxial cable
   Coaxial cable is a network that is coated with 2 levels of insulation. At first there seraut insulation conductor that serves as a conductor to reduce the influence of electromagnetic, there are two plastic insulation that serves as a protector to avoid scratches from cables.
   
   
2. Fiber optic cable
   
   Is the cable network are made using materials from the filament
