Explanation:

Ansible:
- uses SSH for remote device communication
- uses YAML for fundamental configuration elements
Chef:
- uses TCP port 10002 for configuration push jobs
- uses Ruby for fundamental configuration elements
Puppet:
- fundamental configuration elements are stored in a manifest
- uses TCP 8140 for communication
The focus of Ansible is to be streamlined and fast, and to require no node agent installation.
Thus, Ansible performs all functions over SSH. Ansible is built on Python, in contrast to the Ruby foundation of Puppet and Chef.
TCP port 10002 is the command port. It may be configured in the Chef Push Jobs configuration file .
This port allows Chef Push Jobs clients to communicate with the Chef Push Jobs server.
Puppet is an open-source configuration management solution, which is built with Ruby and offers custom Domain Specific Language (DSL) and Embedded Ruby (ERB) templates to create custom Puppet language files, offering a declarative-paradigm programming approach.
A Puppet piece of code is called a manifest, and is a file with .pp extension.
