A state in which a computer, database, or application is put into a temporarily paused or inactive state to perform maintenance, backup, or apply updates safely without affecting active processes or risking data corruption.
You will find this term commonly used in Systems Management
A state in transaction processing where a system temporarily halts operations to reach a consistent state, often for purposes of backup, recovery, or applying system changes. This ensures data integrity during critical maintenance activities.
You will find this term commonly used in Database Management
A consistency model in distributed computing where a system is considered consistent if it is quiescent (i.e., no operations are taking place). It's a less strict form of consistency useful in certain types of distributed systems.
You will find this term commonly used in Distributed Systems
A state of minimal activity or dormancy in a system, where operations are temporarily halted to achieve consistency, perform maintenance, or for safe reconfiguration. In distributed systems, reaching a quiescent state can be crucial for synchronization and consistency.
You will find this term commonly used in Distributed Systems
Temporarily pausing or suspending database activity to perform maintenance tasks such as backups or updates, ensuring that these tasks can be completed without the interference of ongoing transactions or changes.
You will find this term commonly used in Databases
A setting available in many software applications and operating systems that suppresses notifications, alerts, and other interruptions, typically to allow users to focus on tasks without distraction.
You will find this term commonly used in User Experience
In networking, a quiet period is a designated time frame during which network activity is either reduced or halted to allow for maintenance, backups, or to ensure that critical operations can proceed without interference from routine traffic.
You will find this term commonly used in Networking
Policies set in IT environments to define periods during which notifications, updates, or backups are minimized or suspended to avoid disrupting users. This can be particularly important in 24/7 operations or when minimizing interruptions is critical.

You will find this term commonly used in Distributed Systems
A consensus mechanism used in blockchain networks where a transaction is considered valid and can be added to the block only if it gets approval from a majority (quorum) of nodes, ensuring security and reliability in decentralized systems.
You will find this term commonly used in Blockchain/Cryptocurrency
A method used in distributed systems to achieve consensus or agreement among distributed processes or nodes, ensuring that a majority (or a specified subset) agrees on a given action before it is executed, thus maintaining consistency and reliability.
