Prioritizing a 'Secure Boot Process' is essential for ensuring the safe transmission of IoT data. This process ensures that only trusted, authenticated firmware and software are loaded onto devices, preventing unauthorized access and enhancing security. While data encryption, device authentication, and predictive maintenance algorithms are important, securing the boot process is the first line of defense.

An SSD, which stands for 'Solid State Drive,' uses NAND-based flash memory to store data. It is significantly faster in terms of data access compared to traditional HDDs (Hard Disk Drives) because it has no moving parts, resulting in quicker data retrieval. SSDs are commonly used for faster storage and improved system performance.

Data Sharding is a technique in distributed databases where a database is divided into smaller parts called "shards," and each shard is stored on different servers. This improves data distribution and scalability.

The technique that visualizes tasks on a board for easy tracking is 'Kanban.' Kanban is widely used in Agile project management, allowing teams to manage work in progress effectively and optimize flow.

"SSID" stands for "Service Set Identifier" (Option c). It is a unique name used to identify a wireless network. When connecting to a Wi-Fi network, users select the network with the matching SSID. This helps users distinguish between different networks.

In IT Service Management (ITSM), a 'best practice' refers to a standard or set of guidelines for achieving a specific objective or task effectively. It provides recommendations and proven methods, but it doesn't require the use of a particular tool or approach. A Process Model outlines how a specific process works, a Service Catalog lists available services, and a Change Request Form is used to request changes in IT services.

For data visualization with many categories, a 'Treemap' chart is useful. It displays hierarchical data in a compact way, with nested rectangles representing different categories.

'Encapsulation' is a key concept in object-oriented programming that involves bundling the internal state and methods into a single unit (a class) and allowing interaction through well-defined interfaces, thus hiding implementation details.

'Change Management' in ITSM focuses on controlling and managing changes to the IT infrastructure. It aims to minimize the negative impact of changes, ensuring that they are planned and implemented effectively.

In IT governance, the principle that ensures stakeholders' rights are protected and taken into consideration is 'equity.' This means that the interests and concerns of all stakeholders are fairly addressed, promoting fairness and inclusivity.
