Final answer:
The most appropriate e-business form for direct computer-to-computer exchanges in a B2B context is Electronic Data Interchange (EDI), which allows for the structured electronic transmission of data between organizations.
Step-by-step explanation:
If the government agency wishes to implement a system for computer-to-computer exchanges between buyers and sellers, the most appropriate form of e-business in the B2B market would be Electronic Data Interchange (EDI). EDI allows for the structured transmission of data between organizations by electronic means. It represents a set of standards for structuring information that is to be electronically exchanged between and within businesses, facilitating B2B transactions and communication.
e-Marketplaces and e-procurement systems are also related to B2B transactions, but they serve different purposes. E-marketplaces are virtual places where companies meet to trade, similar to physical marketplaces, but online. E-procurement is the business-to-business or business-to-consumer or business-to-government purchase and sale of supplies, work, and services through the Internet as well as other information and networking systems. Finally, online advertising is about promoting a company's products or services over the internet. But for direct computer-to-computer transactions and exchanges, EDI remains the best and most efficient solution.
