Customers can shop anytime, anywhere, without the constraints of physical store hours. They can browse products, compare prices, and make purchases with just a few clicks. For businesses, e-commerce eliminates the need for a physical store and reduces operational costs associated with maintaining a brick-and-mortar establishment.

(b)       List any two examples of E-commerce.

Ans:- Two examples of e-commerce are:

1. Amazon: Amazon is an online marketplace where customers can purchase a wide range of products, including electronics, books, clothing, and more. It operates globally and offers both physical goods and digital products.

2. eBay: eBay is an online auction and shopping website where individuals and businesses can buy and sell a variety of products. It facilitates both consumer-to-consumer and business-to-consumer transactions.

(c)       What is Digital Certificate?

Ans:- A digital certificate is a digital document that verifies the identity of an entity, such as a website or an individual, and enables secure communication over the internet. It is issued by a trusted third-party called a Certificate Authority (CA). Digital certificates use cryptographic techniques to ensure the authenticity and integrity of the information exchanged between parties.

(d)       Write any two technical disadvantages of E-commerce.

Ans:- Two technical disadvantages of e-commerce are:

1. Security Risks: E-commerce transactions involve the exchange of sensitive information, such as credit card details and personal data. This makes e-commerce susceptible to security risks, such as hacking, data breaches, and identity theft. Ensuring robust security measures and encryption is crucial to protect customer information.

2. Technical Infrastructure Requirements: E-commerce relies heavily on a stable and efficient technical infrastructure, including servers, networks, and databases.

2. Online Banking: Many banks offer online banking services that allow customers to transfer funds, pay bills, and make purchases online. Customers can access their accounts through secure websites or mobile applications.

3. Mobile Payment Systems: With the rise of smartphones, mobile payment systems have become popular. They enable users to make payments through their mobile devices using applications like Apple Pay, Google Pay, or Samsung Pay. These systems use near-field communication (NFC) or QR codes to facilitate transactions.

Ans:- Encryption is a process of converting data into a form that is unintelligible to unauthorized individuals, ensuring its confidentiality and integrity. Various types of encryption algorithms and methods exist. Here are some common types of encryption:

1. Symmetric Encryption: Also known as secret-key encryption, symmetric encryption uses a single key for both the encryption and decryption processes. The same key is used to encode and decode the data. Examples of symmetric encryption algorithms include Advanced Encryption Standard (AES) and Data Encryption Standard (DES).

2. Asymmetric Encryption: Asymmetric encryption, also called public-key encryption, uses a pair of mathematically related keys: a public key and a private key. The public key is used for encryption, while the private key is used for decryption. This method allows secure communication without the need for a shared secret key. Popular asymmetric encryption algorithms include RSA and Elliptic Curve Cryptography (ECC).

3. Hash Functions: Hash functions are one-way algorithms that convert input data into a fixed-length string of characters. They are commonly used for data integrity and digital signatures. A hash function generates a unique hash value for each unique input, making it highly unlikely for two different inputs to produce the same hash value. Common hash functions include MD5, SHA-1, and SHA-256.

4. Transport Layer Security (TLS): TLS is a cryptographic protocol used to secure communication over networks. It provides encryption, authentication, and integrity for data transmission. TLS is commonly used to secure web traffic (HTTPS) and other network protocols.

5. Virtual Private Networks (VPNs): VPNs use encryption protocols to create secure tunnels over public networks, such as the internet. They provide privacy and data security for remote users accessing corporate networks or individuals seeking to protect their online activities. Common VPN protocols include IPsec (Internet Protocol Security) and OpenVPN.
