Quite a bit of information is available here. Among the highlights:
• processor — Provides each processor with an identifying number. If you only have one pro-
cessor, you will only see a 0. However, if you are using a machine with multiple processors, each
of the processors will have it own number, increasing by one as you go down the list, and its own
collection of information.
• cpu family — Authoritatively tells you the type of processor you have in the system. Simply
place the number in front of "86" to calculate the value. This is particularly helpful if you are
wondering about the architecture of an older system (686, 586, 486, or 386). As RPM packages
are occasionally compiled for particular architectures, this value tells you which package to install
on the system.
• model name — Gives you the popular name of the processor, including its project name.
• cpu MHz — Shows the precise speed in megahertz of that particular processor (in thousandths).
• cache size — Tells you the amount of level 2 memory cache available to the processor.
• flags — Defines a number of different qualities about the processor, such as the presence of a
floating point unit (FPU) and the ability to process MMX instructions.

This file displays the various character and block devices currently configured for use with the kernel.
It does not include modules that are available but not loaded into the kernel. Sample output from this
file looks similar to this:
