Transmission device and method of network card

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network card used for a personal computer (PC). In particular, when an electronic document is received after the computer is turned off, It is about a network card that forwards to a desired address on a network.

As computers became popular and electronic documents became popular, the transmission of documents using computers became a common task.

The transmission of an electronic document using a computer is assigned an e-mail address (E-mail address or account number) of each individual who can identify a user.

The general public distributes the e-mail address as described above, and applies to a service company that commercially provides e-mail services, for example, a service provider such as Cheon Lian, and is assigned an account number. After reassigning, reassign the address for the employee to which it belongs.

Employees who belong to a company or organization can send and receive electronic documents to their assigned e-mail address. However, most companies use their own server, which uses post-only Post Office Protocol 3 (POP 3) as a security measure. And a gateway device in the role of a Fire-Wall that blocks the connection of outsiders in software (Soft Ware).

Therefore, PPP employees who belong to the company or organization can use the computer outside the company that is not connected to the network (Net-Work) or connect to the company network through a regular telephone line with the permission of the network operator when traveling abroad. (Point to Point Protocol) Since communication was required using a server, communication line costs were incurred when traveling long distances.

In addition, some mobile communication providers such as PCS give a mobile phone subscriber an ID number, and when an e-mail arrives, there is a convenient function of notifying that the e-mail has arrived.

Hereinafter, an electronic document transmission apparatus of a network card according to the related art will be described with reference to the accompanying drawings.
