Meaning of GATEWAY in English
A gateway can be either hardware or software that acts as a bridge between two applications or networks so that data can be transferred between a number of computers. When e-mail gets sent between two servers or when you log in to a web site, there is a gateway that allows the connection take place. In a completely unrelated story, Gateway is also the name of a popular direct-order PC manufacter.
