Linux files are like containers that store information. A file is identified by a filename. Files are stored on storage devices such as Hard Drives, Portable storage devices like USB Pen Drives, Floppy Disks, etc.
A sequence of one or more filenames separated by slashes( / ) is called a pathname. A pathname that begins with a slash( / ) is called an absolute pathname. It is the path from the Linux root directory. We can also form relative pathname i.e paths that are relative to the current directory.
