There are four questions in this assignment. Answer all the questions. The examples, whenever asked to be given, should be different from those that are discussed in the corresponding course material.

Question 1:

(a) How is information obtained from Data? Explain with the help of an example. How is knowledge different from information? Explain the quality and value of information.

Ans) Information is obtained from data through the process of analysis, interpretation, and contextualization. Data, which refers to raw facts or figures, must be processed and organized to derive meaningful insights and understanding. This involves identifying patterns, trends, and relationships within the data to extract useful information. For example, analyzing sales data from a retail store can reveal customer preferences, purchasing patterns, and market trends, providing valuable insights for decision-making.

Knowledge differs from information in that it involves understanding and insight derived from information. While information represents processed data, knowledge involves the application of understanding, experience, and expertise to interpret and use that information effectively.

The quality of information refers to its accuracy, reliability, relevance, and completeness. Valuable information is trustworthy, timely, relevant to the context, and provides actionable insights. Organizations strive to ensure the quality of their information to support informed decision-making and enhance organizational effectiveness.

(b) What is ICT? How is ICT useful in the present time? What is the digital divide and how it can be reduced?

Ans) ICT stands for Information and Communication Technology, which refers to the use of technology to manage and process information, and facilitate communication and collaboration. It encompasses a wide range of technologies, including computers, software, telecommunications equipment, and the internet.

ICT is highly useful in the present time as it enables individuals, businesses, and governments to access, store, process, and share information rapidly and efficiently. It facilitates communication and collaboration across geographical boundaries, enhances productivity, supports innovation, and enables access to a wealth of information and resources.

The digital divide refers to the gap between those who have access to ICT and those who do not, often due to factors such as income, education, geographical location, and infrastructure. To reduce the digital divide, initiatives such as improving internet infrastructure, providing affordable access to ICT resources, offering digital literacy programs, and promoting inclusive policies are essential. Additionally, fostering partnerships between governments, businesses, and civil society organizations can help address inequalities in ICT access and usage.

(c) Define the term digital identity. Why do you need digital identity in cyberspace? How can you verify digital identity? What are the different cybercrimes that can be committed if the digital identity of a person is revealed?

Ans) Digital identity refers to the unique representation of an individual or entity in the digital realm, typically in the form of electronic credentials or attributes. It includes personal information, such as name, date of birth, username, passwords, digital signatures, biometric data, and other identifiers used to authenticate and verify an individual's online identity.

Digital identity is crucial in cyberspace for several reasons

a) Authentication: It ensures that individuals can access digital services securely and prove their identity online.

b) Authorization: It enables the granting of appropriate access permissions and privileges based on an individual's identity.

c) Trust: It facilitates trust between parties in online transactions and interactions, fostering confidence in the integrity and security of digital communications.

Digital identity can be verified through various methods, including passwords, biometric authentication (such as fingerprint or facial recognition), two-factor authentication (2FA), digital certificates, and identity verification services.

If the digital identity of a person is revealed, it can lead to various cybercrimes, including

a) Identity theft: Fraudsters may impersonate the victim to access their accounts, steal their financial information, or commit other crimes.

b) Phishing attacks: Cybercriminals may use the victim's identity to trick others into disclosing sensitive information or performing malicious actions.

c) Social engineering: Attackers may exploit the victim's identity to manipulate individuals into disclosing confidential information or performing unauthorized actions.

d) Financial fraud: Cybercriminals may use the victim's identity to make unauthorized transactions, open fraudulent accounts, or apply for loans or credit cards.

e) Reputation damage: Disclosure of digital identity can lead to reputation damage, social engineering attacks, or harassment, affecting the victim's personal and professional life.

Question 2:

(a) What is e-Commerce? What are its advantages and disadvantages? Explain the terms Digital Certificate and SSL in the context of eCommerce.

Ans) E-commerce, short for electronic commerce, refers to the buying and selling of goods and services over the internet or other electronic networks. It encompasses various online transactions, including online retail (e-retail), electronic payments, online auctions, and digital marketplaces.

Digital Certificate

A digital certificate is a cryptographic credential that verifies the identity of individuals, organizations, or websites in electronic transactions. It contains information such as the certificate holder's name, public key, issuer, and validity period. Digital certificates are issued by trusted Certificate Authorities (CAs) and are used to authenticate users, secure online communications, and ensure the integrity of digital signatures.

SSL (Secure Sockets Layer)

SSL is a cryptographic protocol used to establish secure and encrypted connections between web servers and clients, such as web browsers. It ensures that data transmitted between the server and the client remains confidential and cannot be intercepted or tampered with by unauthorized parties. SSL certificates are used to authenticate the identity of websites and enable secure communication over the internet, providing trust and confidence to users engaging in e-commerce transactions.
