Hardware

Hardware is the physical material that runs the software on your computer. Hardware also the stuff that runs software. Hardware utilization is broken down into these sample steps starting with user input: Hardware is designed to be fast, software alone can do that.
 * 1) The user tells the computer to run the Linux command "cat /etc/passwd".
 * 2) The computer runs the command cat.
 * 3) The cat program requests read access on the file /etc/passwd.
 * 4) The kernel checks the permissions and if it is readable by the user, the file's contents are read from the hard drive.
 * 5) The cat program receives the file contents.
 * 6) The file is printed.
