Implementing Transport Layer Security (TLS) encryption helps protect sensitive data in transit. TLS is a cryptographic protocol that ensures secure communication over a computer network, commonly used for securing web traffic.

Azure Virtual Machines is the service in Microsoft Azure used to deploy and manage virtual machines. It provides flexibility in terms of choice of operating system, scalability, and configuration.

The CSS property device-width is used to control the size of the viewport. It allows developers to apply styles based on the width of the device's screen, contributing to responsive and adaptive layouts.

The CSS border-radius property is used to create rounded corners. It defines the radius of the element's corners, giving a smooth and rounded appearance.

Infrastructure as Code helps in minimizing human errors. By automating the provisioning and management of infrastructure, IaC reduces the risk of manual mistakes in configuration.

The Builder design pattern focuses on constructing a complex object, allowing for step-by-step construction, while the Prototype pattern emphasizes creating new objects by copying an existing one, focusing on cloning.

Concurrency control in a database management system is the process of managing simultaneous access to the database by multiple transactions. It ensures that transactions can operate concurrently without causing data inconsistencies or conflicts. Techniques like locking and isolation levels are employed to maintain the integrity of data during concurrent access.

The main objective of providing feedback in code review is to improve code quality. Constructive feedback helps developers identify and rectify issues, share knowledge, and maintain coding standards, contributing to a better overall software development process.

The Waterfall Model is best suited for projects with well-defined and stable requirements. It follows a linear and sequential approach, where each phase must be completed before moving to the next. While it may lack flexibility for changing requirements, it is effective when the project scope is clear from the beginning.

The purpose of a database lock in concurrency control is to manage concurrent access to ensure data consistency. Locks are mechanisms used to control access to a shared resource, preventing conflicts that may arise when multiple transactions try to access or modify the same data simultaneously.
