In IT governance, one of the pillars is to ensure that IT resources are used responsibly, efficiently, and 'transparently.' This means that actions and decisions related to IT should be clear and open to scrutiny, promoting accountability and trust.

The 'HR (Human Resources) Module' in an ERP system is responsible for managing various aspects of an organization's human resources, including payroll, employee benefits, and personnel data. It helps streamline HR-related processes.

RAID 1, also known as disk mirroring, is a RAID level that provides fault tolerance by duplicating data on two or more disks. It doesn't involve striping, making it a reliable choice for data redundancy.

High-Performance Computing (HPC) is associated with "scientific and data-intensive tasks." These tasks involve complex simulations, modeling, and data analysis that require immense computational power, often beyond the capability of regular computers.

The activation function that maps its input to values between 0 and 1 is the 'Sigmoid' function. It's commonly used in the output layer of a neural network for binary classification tasks, where it represents probabilities.

To determine a task sequence while honoring dependencies, 'Topological Sorting' is the most appropriate approach. It is commonly used in project scheduling and task management to create a linear order of tasks in a directed acyclic graph (DAG) while ensuring all dependencies are met.

'Cache' is a type of high-speed, volatile memory used to store frequently accessed data and instructions, allowing for faster data retrieval by the processor. It acts as a bridge between slower memory (like RAM) and the processor, enhancing system performance.

The '204 No Content' status code indicates that the server successfully processed the request but is not returning any additional content in the response body. It's often used for operations that have no response data.

Content Delivery Networks (CDNs) are crucial for optimizing web page load times. CDNs distribute content to servers closer to the user, reducing latency and speeding up page loading. They cache assets and reduce the load on the origin server, improving performance.

Representing hierarchical data, such as the structure of an organization, is best done using a 'Tree Diagram' visualization. It visually displays the parent-child relationships between different levels of a hierarchy, making it clear and organized.
