Procfs
The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory. Typically, it is mapped to a mount point named /proc at boot time. Wikipedia

root@edison:~#Devfs
devfs is an obsolete and no longer available virtual filesystem that automatically generated the contents of /dev on some older versions of the Linux kernel. Wikipedia
Sysfs
sysfs is a virtual file system provided by the Linux kernel that exports information about various kernel subsystems, hardware devices, and associated device drivers, from the kernel's device model to user space, through virtual files. Wikipedia
