Here is a detailed explanation of EDI (Electronic Data Interchange) covering its meaning, history, working
concept, and EDI model:

📘 1. Meaning of EDI (Electronic Data Interchange)

EDI is the electronic exchange of standardized business documents between organizations through computers,
without human intervention.
These documents include:
• Purchase Orders
• Invoices
• Shipping Notices
• Inventory Status Updates
✅ In simple terms:
EDI replaces traditional paper-based documents with digital formats and automates transactions between
business systems.

🕰 2. History of EDI
Period Development
New Section 1 Page 6
Period Development
1960s Initial concept developed by the U.S. transportation industry to send cargo information
electronically.
1970s Introduction of standardized formats for inter-company data sharing.
1980s Governments and large corporations began using EDI widely in sectors like retail, healthcare, and
automotive.
1990s Internet-based EDI started, replacing costly VAN (Value Added Networks).
2000s– Cloud-based EDI systems emerged, offering better integration, speed, and scalability.
Present

⚙ 3. EDI Working Concept

🔄 How EDI Works Step-by-Step:
1. Data Preparation
○ A business (e.g., a retailer) prepares data like a purchase order using its internal software.
2. Data Translation
○ The data is converted into a standardized EDI format (e.g., ANSI X12, EDIFACT).
3. Data Transmission
○ The EDI document is transmitted via a secure communication method (e.g., Internet, FTP, or VAN).
4. Data Reception
○ The receiving company’s system receives the EDI file and automatically processes it.
5. Integration
○ The data is translated back into a format the receiving system can understand and is stored in their internal
database.

🧾 Example:
A retailer sends an EDI Purchase Order (PO) to a supplier, who automatically receives and processes the order,
then sends back an EDI Invoice and Shipping Notice.

📊 4. EDI Model
The EDI model defines the components and flow of the EDI system.
📦 Components of EDI Model:
Component Description
Application Layer Internal business systems (ERP, accounting, inventory).
Translation Layer Converts data to/from standard EDI formats (using EDI software).
Communication Layer Transfers EDI documents using protocols like FTP, HTTP, AS2, or VAN.
EDI Standards Rules for formatting EDI documents (e.g., ANSI X12, EDIFACT, TRADACOMS).

manual formats to fully automated, internet-based systems. A well-designed EDI model streamlines operations,
improves data accuracy, and enhances supply chain collaboration.

• Region: International, especially Europe and Asia.
• Developed by: United Nations (UN/EDIFACT).
• Common Uses: International trade, government data exchange.
• Example: ORDERS (purchase order), INVOIC (invoice).

3. 🇬🇧 TRADACOMS (Trading Data Communications Standard)

• Region: Mainly used in the United Kingdom.
• Industry: Retail sector.
• Successor: Now largely replaced by EDIFACT.

4. 🏥 HL7 (Health Level Seven)

Here’s a clear explanation of the Secure Transaction Concept, focusing on Authentication and Authorization — two
key pillars of online security.

🔐 Secure Transaction Concept

A secure transaction ensures that data, money, or services exchanged between two parties (like you and a
website) are safe from fraud, theft, or misuse.
Two major steps in a secure transaction are:

✅ 1. Authentication
Authentication means proving your identity — making sure you are who you claim to be.
Examples:
• Entering your username and password
• Using a fingerprint scanner
• Entering a One-Time Password (OTP)
• Face recognition or biometric scan
Goal: Verify that the person trying to access the account is the real owner.

🔓 2. Authorization
Authorization means giving permission — deciding what you're allowed to do after you're authenticated.
Examples:
• Allowing access to view bank balance
• Allowing a user to transfer money
• Giving someone admin rights in a system
• Limiting a guest user to read-only access
Goal: Ensure that the authenticated user can only perform actions they are allowed to.

🔁 Authentication vs Authorization:
Feature Authentication Authorization
Meaning Confirming identity Granting permissions
Occurs when? First step in a secure transaction After authentication is successful
Example Entering password or OTP Accessing account settings or money transfer
Checks Who are you? What are you allowed to do?

🔒 Real-Life Example:
When you use net banking:
1. You log in using your password → Authentication
2. You try to transfer money, and the system checks if you’re allowed → Authorization

Here’s a simple and clear explanation of Cryptography, Encryption & Decryption, and security protocols like SSL
and SET:

🔐 Cryptography
Cryptography is the science of protecting information by converting it into a secret format, so that only the
intended person can read or use it.
It keeps data safe during transmission over the internet.

🔑 Encryption & Decryption

Term Meaning
Encryption Converting plain text (readable data) into cipher text (secret code) using a key
Decryption Converting cipher text back into plain text using a key
Example:
• Plain Text: Hello
• Encrypted (Cipher Text): Xpsme! (just an example)
• Decrypted: Hello again
Goal: To ensure that even if someone intercepts the data, they can’t read it without the decryption key.

🔒 SSL (Secure Sockets Layer)

SSL is a security protocol used to encrypt data that is transferred between your browser and a website.
🔍 Features of SSL:
• Uses encryption to keep data safe
• Ensures data privacy and integrity
• Used in https:// websites (the "s" means SSL is active)
• Often replaced now by TLS (Transport Layer Security)
When you see 🔒 in the address bar, it means SSL/TLS is protecting your data.

💳 SET (Secure Electronic Transaction)

SET is a security protocol developed by Visa and MasterCard for secure online credit card transactions.
🔍 Features of SET:
• Uses digital certificates to verify users
New Section 1 Page 23

Sure! Here's a clear explanation of each term:

1. Firewall
A firewall is a security system designed to monitor and control incoming and outgoing network traffic based on
predetermined security rules. It acts as a barrier between a trusted internal network (like your home or office
network) and untrusted external networks (like the internet).
• Purpose: To block unauthorized access while allowing legitimate communication.
• Types:
○ Hardware firewall: A physical device.
○ Software firewall: Runs on computers or servers.
• How it works: It inspects data packets and decides whether to allow or block them based on rules like IP
addresses, ports, or protocols.

2. Digital Certificates
A digital certificate is an electronic "passport" that verifies the identity of a website, individual, or organization
online.
• Issued by a Certificate Authority (CA), a trusted third party.
• Contains information like the owner’s public key, the owner's identity, the CA's signature, and expiration date.
• Used in SSL/TLS to secure websites (HTTPS), ensuring:
○ The site is authentic.
○ Data exchanged is encrypted.
• Think of it like a driver’s license for websites or users proving who they are on the internet.

3. Digital Signatures
A digital signature is a cryptographic technique used to verify the authenticity and integrity of digital messages or
documents.
• Created using the sender's private key.
• When someone receives a digitally signed document, they use the sender’s public key to verify:
○ That the document was indeed sent by the claimed sender.
○ That the document has not been altered after signing.
• Ensures non-repudiation — the sender cannot deny having sent the document.
• Commonly used in contracts, emails, and software distribution.

Summary:
• A firewall protects your network by controlling traffic.
• A digital certificate proves the identity of websites or users online.
• A digital signature guarantees the origin and integrity of a digital message or document.
If you want, I can also provide simple real-life analogies for these concepts!
