Data Transmission Method for Data Transmission System

A data transmission method for data transmission system, comprising the steps of:

• (1) providing a data transmission system having a data transmission device, at least one host computer and at least one associated computer, wherein each of the at least one host computer and the at least one associated computer are installed with a switching application, and the switching application setting a plurality of switching system clipboards in each of the at least one host computer and the at least one associated computer;
• (2) a first user operating any one un-operation computer of the at least one host computer and the at least one associated computer for making the un-operation computer become one first under-operation computer, so as to select a first data and then treat the first data with a first cut command or a first copy command;
• (3) the first data being stored into the computer clipboard of the first under-operation computer, and simultaneously stored into a first switching system clipboard of the plurality of switching system clipboards in each of the at least one host computer and the at least one associated computer;
• (4) the first user carrying out a first computer switching operation through the data transmission device, so as to operate any one un-operation computer of the at least one host computer and the at least one associated computer for making the un-operation computer become the other one first under-operation computer;
• meanwhile, the first data stored in the first switching system clipboard being further stored into the computer clipboard of the first under-operation computer;
• and
• (5) the first user making a first paste command by operating the first under-operation computer, so as to show the first data in the operation window of the first under-operation computer.
