What are the applications of information technology?

Answer: Logistics information technology mainly includes \x0d\ 1 and commodity barcode coding scanning system \x0d\ Barcode technology is an automatic identification technology, aiming at realizing automatic scanning of information. \x0d\2。 The basic working principle of POS (point of sale) \ x0d \ POS system is to first create commodity data in a computer file, and directly read the barcode on the commodity through the online structure of the computer cash register (or directly input the code through the keyboard), and then the commodity information can be displayed immediately, thus speeding up the cash register speed and correctness. The detailed information of each commodity sale is automatically recorded and then returned to the computer by the connection framework. Through computer calculation and processing, various sales statistics and analysis information can be generated as the basis for management. \x0d\3. EDI (Electronic Data Interchange) \ x0d \ EDI is the direct transmission of standard business documents between enterprise computer systems. Using EDI system can make enterprises communicate and exchange information with their suppliers quickly, realize one-on-one long-term cooperation with suppliers, and help to establish an integrated supply chain logistics management system. \x0d\4。 Internet \ x0d \ Internet technology is mainly used for information transmission and can be used for information management. Enterprises can use the Internet to communicate and feedback information to upstream and downstream enterprises in time. \x0d\5。 Radio frequency technology \x0d\ Radio frequency technology can improve the level of logistics operation. It can be used for warehousing, transportation and cargo tracking. \x0d\6。 Satellite communication technology \x0d\ Satellite communication technology is used for information transmission, which realizes a large number of rapid information transmission through satellites and is a technology used in the process of logistics information management.
