What is master-slave used for?
Master/slave is a model of asymmetric communication or control where one device or process (the “master”) controls one or more other devices or processes (the “slaves”) and serves as their communication hub.
What is difference between master and slave?
Master vs Slave Simply, a master is a device or a process that controls other devices or processes and a slave is a device or a process that is controlled by another device or a process. Communications based on master/slave model occurs in many places.
What is master-slave design?
The Master/Slave design pattern is another fundamental architecture LabVIEW developers use. It is used when you have two or more processes that need to run simultaneously and continuously but at different rates. If these processes run in a single loop, severe timing issues can occur.
What is a feature of the master-slave model?
In the master/slave (sometimes called boss/worker) model, a master entity receives one or more requests, then creates slave entities to execute them. Typically, the master controls the number of slaves and what each slave does. A slave runs independently of other slaves.
Is technology a slave or master?
Th is series of questions has brought about a debate as to “whether technology is a master or a slave.” Th ose who claim that technology is a master believe that human beings have become slaves to technology in the sense that their entire lives are fashioned and controlled by technology.
What is master-slave in computer architecture?
In computer networking, master/slave is a model for a communication protocol in which one device or process (known as the master) has total control one or more other devices or processes (known as slaves).
How do I create a master-slave database?

WHAT IS features of master-slave model?
Is CAN bus a master-slave?
CAN allows multiple devices (referred to as “nodes”) to connect to each other on a single bus, as shown in Figure 1. Unlike other protocols, such as I2C and SPI, CAN nodes do not have strict master/slave roles.
Why do we need master-slave architecture?
Master-slave architectures are used to help stabilize a system. Master is the true data keeper while a slave is a replication of master. Cache/caching is an option but using it as complementary to the master-slave system would be better. Replication is the process of synchronizing data from the master to slave.
How master-slave works in MySQL?
The master has a thread, called the dump thread, that continuously reads the master’s binlog and sends it to the slave. The slave has a thread, called the IO thread, that receives the binlog that the master’s dump thread sent, and writes it to a file: the relay log.
What is master-slave MongoDB?
MongoDB’s Master/Slave approach is using a replica set with its replication and election mechanisms where there is only one Primary and a few secondaries at any given time.
