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.

Single-Tenancy refers to the practice of allocating a dedicated portion of a public cloud for a single tenant or organization, providing isolation and control over resources.

The concept described is 'Data Integration' in ERP. It ensures that data is entered once and can be accessed by multiple applications without duplication. This enhances data accuracy and consistency across the organization.

A/B testing, or "split testing," is a method where different versions of an application are released to different user groups. It's a technique used to assess the impact of changes before a full release.

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.

A neural network with three or more layers, including input, output, and one or more hidden layers, is termed as a "Deep Learning Network." Deep networks are known for their ability to model complex relationships.
