Software that manages computer hardware and provides services to programs.

Lightweight, transportable packages containing applications and their dependencies, enabling consistent environments across different systems.

A layer allowing multiple virtual machines (VMs) to run on a single physical machine, managing their resources.

A model where components on networked computers coordinate by exchanging messages. It focuses on scalability, reliability, and resource management for better performance.

An architectural style that breaks down an application into smaller, independent services that communicate with each other.

The smallest unit of storage in a file system, typically 4 KB, used to manage data.

A data structure that stores information about a file, like its size, ownership, and location on the disk.

Data that describes other data, such as file size, type, and modification dates, helping organize and retrieve files.

The state where files are scattered in pieces across the disk, slowing down access times.

The process of making a file system accessible at a specific point in the directory structure.

The process of making a file system inaccessible.

A feature that automatically detects and fixes data corruption without user intervention.

A measurement indicating how many read/write operations can be executed per second on a storage device.

The duplication of critical components or functions to increase reliability and prevent data loss.

The ability of a system to function reliably and minimize the impact of errors.

Actions taken to prevent a system from entering an unsafe state, potentially causing harm.

Checks to ensure inputs and system variables are within expected ranges, preventing errors.

Methods to limit the effects of failures on a system by isolating the problem.

Creating copies of data or processes to enhance reliability and availability.

Strategies to minimize the negative consequences of failures, reducing their impact on a system.

Hiding faults from users to keep a system performing smoothly.

Procedures designed to restore normal operation after a failure.

A unique identifier assigned to each network interface, allowing switches to forward data to the correct device within a local network.

Devices that operate at the Data Link Layer, using MAC addresses to route data packets to their correct destinations within a local network.

Mechanisms implemented to detect and correct errors that may occur during data transmission, ensuring data integrity.

A unique address assigned to a device on a network, categorized into public (routable) and private (non-routable) addresses.

A technology that uses a unique address (VLAN ID) to group devices on a network, providing increased security and efficiency by segregating traffic.

A technology that translates private IP addresses used within a local network to public IP addresses for communication with the internet.
