in this section, we're going to be looking at operating systems and how they organized files and folders on your drives.
They also provide tools to help you to browse through the folders and files.
What I mean by drives is hard disks, but also USB flash drives, SD cards, CDs, DVDs and so on.
Martin desktop computers literally store millions of parts off their hard disks.
Fortunately, we don't have to deal with one long list off millions of files
to make life simpler for us.
Bars are organized into folders
rather like boulders in a filing cabinet. Make it easy to find the particular fires you're looking for rather than just having a big box. So you just throw all the parts in
different operating systems, provide tools like Windows Explorer on Apple's find out applications.
They allows to browse through these folders and see what is inside a folder.
Boulders are organized in a hierarchy,
beginning with the root folder at the top and then sub folders underneath it.
in Windows, we call it the Root folder in Lenox Systems. They often use the term directory,
but the root directory root folder talking about the same thing, just different terminology.
So folders can have inside them other folders, which are some folders or they could have files.
Here is the latest version of Windows Explorer.
Not that there are subtle differences in the way Explorer looks in each version of windows, but it generally looks like this.
The window is divided vertically, but between the navigation pane and the details pain.
Believe it or not, the navigation pane is used to navigate through the folder structure and to look inside a particular polled and see what's in there.
The details Pain shows you the contents of the folder for the disk drive that you have chosen in the navigation pane.
In the navigation pane, you will see a list off disk drives that Windows has found on the computer.
This one, as I said, include heart desks, CDs, DVDs, USB, flash drives or any other removable media that you have a plan B in
in the details pain on the right.
You could see the contents of the folder that you have clicked on.
Folders remember, can contain other folders called sub folders, so these are really the sub folders that you're seeing here.
Photos can also, of course, contain files
over at the top. Off the window there is the address file
on this shows you where you've been navigating to. In other words, what do you actually looking at in the details pain.
In this case, it just says when you're looking at the root of the C drive, you haven't got into any sub folders within the C drive.
Other operating systems have their own versions off Windows Explorer,
for example. This is the files utility in Boone, too.
as you can see, very similar to Windows Explorer. The same basic concept in a ll, the different operating systems.
Okay, so now we reached the end of module 1.1.
here's what we have covered.
We looked at the basic functions, often operating system. We saw that it provides a user friendly interface that users could use to interact with the computer.
We saw that it coordinates all of the hard way the CPU, the ran the hard drive and so on.
It also provides environment in which software applications could run.
It monitors your system, help on functionality, and report errors to you.
And finally we saw that it displays the structure and directories or data management.
We saw that broadly speaking comp TIA categorizes operating systems as either mobile operating systems or workstation operating systems by mobile operating systems. We mean those that were designed for mobile devices like smartphones, tablets and so on.
Bye workstation we bi desktop computers on laptop computers.
We also saw that this distinction is starting to blur with Windows 10
because when does 10. Actually it can run on mobile devices and it can run on workstations.
But most operating systems are specific.
So we saw that on
mobile devices. We have IOS from Apple. We have android for Google,
and you have Windows 10 available
workstations, that is, desktops and laptops. We have chrome os.
We have Oh, it's X from Apple.
We have windows from Microsoft, and then we have many different varieties off limits available. A swell.
We talked about software compatibility and the fact that a given application is compiled for a given operating system on a particular version of the operating system, and therefore you can't just take any application and install it on any system.
You have to check the requirements of the application to make sure that it's designed for the operating system you have on the particular version of the operating system that you have
talked about the issue off hardware compatibility
so applications may indicate that certain minimum hardware is required in order to run. The application should verify that as well,
before purchasing the application.
We also know that the issue of 32 bit on 64 bit
We saw that
with 32 Betsy P. Use. Yoon stole 32 bit operating systems but 64 bit CB use. You could install either a 32 bent or a 64 bit operating system.
We also saw that
what applications you install might also depend on the witness off the operating system.
So 32 bit operating systems need 32 bit applications. 64 bit operating systems can grant both 32 bit and 64 bit applications.
