Explanation:
http://juniper-basic.blogspot.com/2017/02/juniper-basic.html
Junos OS functionality is compartmentalized into multiple software processes.Each process handles a portion of the device’s functionality. Each process runs in its own protected memory space, ensuring that one process cannot directly interfere with another. When a single process fails, the entire system does not necessarily fail.This modularity also ensures that new features can be added with less likelihood of breaking current functionality.The Junos OS is the trusted, secure network operating system powering the high-performance network infrastructure offered by Juniper Networks. The Junos kernel is based on the FreeBSD UNIX operating system, which is an open-sourcesoftware system.
