Read MoreMost Common Flags Used in /proc/cpuinfo
The /proc/cpuinfo file is a virtual file system that provides detailed information about the CPU installed on your system. By examining the flags in this file, we can understand the capabilities and features supported by our processor, including instruction set extensions, virtualization support, and security features. Virtual File Systems Overview A virtual file system (VFS) is an abstraction layer that presents data as files without storing them on physical disk. Linux uses virtual filesystems in the /proc directory to expose kernel and hardware information. These files are dynamically generated when accessed and don't consume disk space. ...
