Change Management is a crucial practice in information assurance that ensures that only authorized modifications are made to an organization's assets, including hardware, software, and data. It involves a structured process of requesting, reviewing, and approving changes to maintain system integrity and security.

Continuous Integration (CI) is the practice of merging code frequently into a shared repository to ensure early detection of integration problems and maintain code quality throughout the development process.

IGMP, or Internet Group Management Protocol, is specifically designed for the management of multicast group memberships. It operates at the Network layer of the OSI model and is used by routers to learn about active multicast groups on a network.

In the absence of parentheses, most programming languages follow the order of operations (PEMDAS/BODMAS). This means that 'multiplication' is performed before addition, subtraction, and division. It's important to understand these rules for correctly evaluating mathematical expressions in code.

RAM (Random Access Memory) is a component of a computer that 'temporarily stores data' that the CPU is currently processing. It provides fast access to data and programs that are in use.

The main difference between a shallow neural network and a deep neural network is the 'number of layers.' Shallow networks have only a few layers, while deep networks have many hidden layers.

A 'Man-in-the-Middle (MitM) Attack' is a form of cyberattack where an attacker intercepts and possibly alters communications between two parties without their knowledge, compromising data integrity and privacy.

'Black-Box Testing' is a type of penetration testing where testers simulate an attacker with no prior knowledge of the target infrastructure. The goal is to identify vulnerabilities as if they were an external attacker.

MQTT is widely used in IoT because it's designed for low-power, efficient communication. MQTT's publish-subscribe model minimizes overhead and is well-suited for resource-constrained devices.

In IT governance, 'COBIT' (Control Objectives for Information and Related Technologies) is a framework that emphasizes decision rights, accountability, and governance to ensure that IT is used in a way that aligns with business objectives and encourages desirable behavior.

The technique you're describing is 'L1 Regularization.' It adds a penalty term to the loss function for large weights, encouraging the model to use only the most important features and prevent overfitting.

The primary purpose of a 'firewall' in network security is to enforce access control policies. It acts as a barrier between a trusted network and an untrusted network, allowing or blocking network traffic based on predefined rules.
