Stepping ID is a product revision number assigned due to fixed errata or other changes. The actual processor model is derived from the Model, Extended Model ID and Family ID fields. If the Family ID field is either 6 or 15, the model is equal to the sum of the Extended Model ID field shifted left by 4 bits and the Model field.

This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
dmidecode is a free userspace command-line utility for Linux that can parse the SMBIOS data. [2] [3] The name dmidecode is derived from Desktop Management Interface, a related standard with which dmidecode originally interfaced. SMBIOS was originally named DMIBIOS.
Linux also calls the threads of this process idle tasks. [2] In some APIs, PID 0 is also used as a special value that always refers to the calling thread, process, or process group. [ 3 ] [ 4 ] Process ID 1 is usually the init process primarily responsible for starting and shutting down the system.
The program produces an ordered list of running processes selected by user-specified criteria, and updates it periodically. Default ordering is by CPU usage, and only the top CPU consumers are shown. top shows how much processing power and memory are being used, as well as other information about the running processes.
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.
