RAID, which stands for 'Redundant Array of Independent Disks,' is a technology used in data storage to combine multiple physical disks into a single logical unit for the purpose of data redundancy, improved performance, or both. It helps protect data from disk failures and can enhance data access speed.

A 'SAN' (Storage Area Network) is a virtualized storage model that combines physical storage from various network storage devices into a single storage device. It provides high-speed data access and centralized storage management.

In a router, the table that keeps track of paths to active networks and how to reach them is known as the 'Routing' table. This table is used for making forwarding decisions based on the destination address.

In real-time trading, the order of transactions is critical. A 'Queue' is the most suitable data structure to ensure the first transaction entered is the first one processed. It follows a First-In-First-Out (FIFO) order, which aligns with transaction sequence requirements.

The process you're referring to is 'Service Catalog Management.' It's a key component of IT Service Management (ITSM) and involves defining and maintaining the live IT services catalog. This catalog contains information about the available services, ensuring that stakeholders have a clear understanding of the IT services provided.

The SQL command 'ALTER TABLE' is used to modify the structure of an existing table, such as adding, deleting, or modifying columns. It's a crucial operation in database management.

The primary operating system running on the host machine in virtualization is often referred to as the 'Hypervisor.' A hypervisor manages and facilitates the execution of multiple guest operating systems.

To ensure high availability, implementing 'redundancy' is essential. This means duplicating critical components across multiple data centers, ensuring the application remains available even if one center fails.

The General Data Protection Regulation (GDPR) is a regulation in EU law that mandates the protection of personally identifiable information (PII) for EU citizens. It sets strict rules for data privacy and security.

'Agile Development' is a software development approach that involves writing code in short, consistent cycles called iterations or sprints. It emphasizes collaboration with stakeholders, adaptability, and continuous delivery.
