System architecture.
There are two type of system architectures.
There are 32-bit and 64-bit,
and they are depending on your CPU,
the chipset that is installed inside of your computer.
The chipset comes again as a
32-bit processor or 64-bit.
The main difference between 32 and 64-bit is the
one that I highlighted in this paragraph, which says a
big difference between 32-bit processor and a 64-bit
processor is the number of calculations per second
they can perform. The rest,
whatever is written, I want you to read it.
But the primary difference is the
one is highlighted in bold.
So when you have a 32-bit system and
when you have a 64-bit system, you could
run 32-bit applications on a 64-bit system.
However, you cannot run 64-bit
applications on a 32-bit system.
So when you are going and talking to
your vendors, talking to your hardware manufacturers, you're
going to have to decide what kind of
architecture that you want for your computer.
And it also depends on the user who is requesting the
compute to have the application installed on it, what kind of
architecture they want. In Linux, the command to find out whether
it's a 32-bit system or 64 it's just by running
a simple command arch, architecture. In Windows, go to My Computer,
right click, and go to Properties.
You should be able to see if your
computer is 32-bit or 64-bit.
So as an exercise for you right now at
this point, I want you to go onto your
Windows machine and find out what is your architecture.
What is your CPU chipset architecture?
Is it 32-bit or is it 64-bit?
I bet you, most of you will find that out today.
Let's run this command in our Linux environment and
then we'll see how the output comes out.
So I'll go into my Linux lab machine.

You don't have to be root to run this command.
So I'll simply run arch, and here it would
tell you, the last two digits is 64-bit.
You could also get this information from another command
that we have learned is uname -a, and
uname -a right here, somewhere in the middle
or close to the end, you will see the
architecture is showing as 64-bit operating system.
The reason I have added arch command, which
is very short, is because sometimes you do
have to run certain scripts in your environment,
and you need to find out information about
your architecture by running simple command.
So architecture is another thing that when you
log into any of the machine, please run
it, try it, what are the architectures,
and also, I would highly recommend you to go
online, and read little more about the difference
between 32-bit and 64-bit architecture. Thank you.
