Electronic commerce facilitates a wide range of business and consumer activities. Key applications include:

• Retail and Wholesale: Online shopping platforms allow businesses to sell products directly to consumers (B2C) or to other businesses (B2B) through digital storefronts, eliminating geographical barriers.
• Online Banking and Financial Services: Customers can perform fund transfers, pay bills, and manage investments securely through electronic portals, reducing the need for physical branch visits.
• Digital Content Delivery: The distribution of intangible goods such as music, e-books, software, and streaming services directly to the user's device.
• Online Auctions and Marketplaces: Platforms that connect buyers and sellers for competitive bidding or fixed-price transactions, such as eBay or specialized procurement sites.
• Supply Chain Management: Integration of electronic systems to track inventory, automate procurement, and streamline logistics between manufacturers, suppliers, and distributors.

Electronic Data Interchange (EDI) is the computer-to-computer exchange of business documents in a standard electronic format between business partners. It replaces traditional paper-based transactions like purchase orders, invoices, and shipping notices with structured digital data, allowing systems to process information automatically without human intervention.

Key characteristics of EDI include:

• Standardization: It uses globally recognized formats (such as ANSI X12 or EDIFACT) to ensure that different computer systems can interpret the data correctly.
• Automation: By eliminating manual data entry, EDI significantly reduces processing errors and speeds up business cycles.
• Security and Reliability: EDI transactions are typically transmitted over secure networks, such as Value Added Networks (VANs) or secure protocols like AS2, ensuring data integrity and non-repudiation.
• Efficiency: It lowers administrative costs and inventory overhead by enabling real-time communication between suppliers, manufacturers, and retailers.
