Pseudo-Distributed Mode is a configuration where Hadoop components run on separate machines but are managed manually. This means that the NameNode, JobTracker, and DataNodes/TaskTrackers are all running on different machines, but they're started and managed by the user instead of a cluster management system like YARN or Apache Ambari. It's useful for testing MapReduce programs on a small scale before deploying them to a full Hadoop cluster.
