In the absence of parentheses, most programming languages follow the order of operations, and 'multiplication' is performed before addition, subtraction, and division.

The 'Open-Closed Principle' is a fundamental design principle in object-oriented programming. It suggests that software entities (such as classes) should be open for extension (new functionality can be added) but closed for modification (existing code remains unchanged). This encourages modularity and maintainability.

'Deduplication' is a data reduction technique that involves eliminating duplicate copies of data, thus reducing data redundancy. This process saves storage space and improves efficiency.

In High-Performance Computing (HPC), applications often require massive data processing in real-time. In this context, 'memory bandwidth' is crucial because it determines how quickly data can be read from and written to memory. A high memory bandwidth is essential for feeding the processors with data at a rate that matches their processing capabilities, ensuring efficient execution of HPC tasks.

'Principal Component Analysis (PCA)' is a commonly used technique in data visualization to reduce the dimensionality of high-dimensional data while preserving as much variance as possible, making it suitable for 2D or 3D visualization.

The 'SRP' (Single Responsibility Principle) is a principle in software engineering that states that a module, class, or function should have only one reason to change. This helps in maintaining a system by reducing the impact of modifications.

The primary benefit of using a 'Virtual Private Cloud (VPC)' in a public cloud environment is 'enhanced security.' VPCs provide isolated network segments within the public cloud, allowing users to define their own network architecture and apply security measures specific to their needs.

The cryptographic concept that allows for selective disclosure of information without revealing unnecessary details is 'Zero-Knowledge Proofs.' In this technique, a prover can demonstrate knowledge of a secret without revealing the secret itself, ensuring privacy and security.

In the context of a cloud-first strategy, 'Data Residency and Compliance' is a priority because it ensures that data is stored in compliance with legal and regulatory requirements, minimizing the risk of non-compliance and data breaches.

To develop a chatbot that generates human-like responses based on context, a 'Long Short-Term Memory (LSTM)' network is suitable. LSTMs are capable of modeling sequences and are widely used for natural language processing tasks, including chatbot development, due to their ability to capture context in conversations.
