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.

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.

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.

Secure Multi-Party Computation (SMPC) is a cryptographic technique that enables multiple parties to jointly compute a function over their inputs while ensuring the privacy of those inputs. It's used in scenarios where data privacy is crucial, such as collaborative data analysis without revealing individual data points.

The approach of 'customization' in ERP entails tailoring the software to meet specific organizational needs. This can lead to longer implementation times but results in a more tailored solution.

Parallel processing in High-Performance Computing (HPC) aims to 'speed up individual tasks' by breaking them into smaller sub-tasks that can be processed simultaneously on multiple processors, increasing overall computation speed.

A network switch primarily serves to 'connect devices' within a local area network (LAN). It intelligently forwards data to the appropriate device based on the device's MAC address, improving network efficiency.

The 'WHERE' clause in SQL is used to filter the results of a query based on a specified condition. It allows you to retrieve specific data that meets certain criteria.

'Containerization' is a virtualization technique that allows running multiple instances or copies of applications on the same hardware, isolated from each other. Containers share the same OS kernel and use fewer resources.

The Spanning Tree Protocol (STP) operates at the Data Link layer and prevents loops in Ethernet networks by creating a loop-free logical topology. It's crucial for network stability and redundancy in Ethernet networks.

A 'Doubly Linked List' is a common choice for implementing an LRU cache. It allows efficient insertion and removal of elements from both ends, making it suitable for the LRU policy.

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.
