How does biometric authentication work, and what are its advantages and limitations compared to traditional authentication methods?
Biometric authentication verifies a user's identity based on unique physical characteristics (e.g., fingerprints, facial features), offering convenience and security, but it may raise privacy concerns and pose challenges in accuracy and spoofing detection.

See lessWhat are the key components of a blockchain network, and how does it ensure data integrity and security?
A blockchain network consists of decentralized nodes, cryptographic hashing, consensus mechanisms, and smart contracts. It ensures data integrity and security through immutable data storage, cryptographic hashing, and distributed consensus algorithms.

See lessHow does a distributed database differ from a traditional centralized database, and what are its advantages and challenges?
A distributed database spans multiple nodes or servers, enabling data replication, fault tolerance, and scalability, but it introduces complexities in data consistency, synchronization, and distributed transaction management.

See lessWhat is the purpose of version control systems (VCS), and how do they facilitate collaboration among software developers?
VCS enables developers to track changes to source code, collaborate on projects, and maintain version history. It allows for code branching, merging, and rollback, ensuring code integrity and facilitating team collaboration.

See lessWhat are the main differences between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) in computer networking?
TCP provides reliable, connection-oriented communication with error detection, retransmission, and congestion control, while UDP offers faster, connectionless communication without guaranteed delivery or reliability mechanisms.

See lessWhat is the role of a load balancer in distributing incoming network traffic across multiple servers?
A load balancer evenly distributes incoming requests across multiple servers (or server instances) to optimize resource utilization, improve scalability, and ensure high availability of web applications or services.

See lessHow does caching improve website performance, and what are the different types of caching mechanisms?
Caching stores frequently accessed data or content in memory or disk, reducing the need for repeated retrieval from the origin server. Common caching mechanisms include browser caching, server-side caching, and content delivery network (CDN) caching.

See lessWhat is the purpose of multi-factor authentication (MFA), and how does it enhance account security?
MFA requires users to provide multiple forms of authentication (e.g., password, OTP, biometric) to access an account, reducing the risk of unauthorized access even if one authentication factor is compromised.
