+A [[Docker]] container is a process or a set of processes with isolated resources that are logically (not physically) allocated from the hard drive by the kernel using `namespacing` and `cgroups`. 
 
+- `namespacing` is an OS feature that segments hardware resources for specific processes. For example, creating separate segments on the hard drive for Python 2 and Python 3, and directing system calls to the appropriate segment based on which application is making the call.
+- `cgroups` (Control Groups) limit the amount of resources (CPU, memory, network bandwidth) a process can use.
