Understanding directories folders and files
I explain why what we think of as folders are sometimes referred to as directories. I do this by showing how directories and files in the Windows command prompt screen are almost identical to what you see as folders and files in the Windows graphical user interface (GUI).

Directory Structure | tree structured directory | acyclic graph directory | operating system | files
#DirectoryStructure #filesystem #operatingsystemlectures
A directory is a container that is used to contain folders and file. It organizes files and folders into a hierarchical manner.
Single-level directory –
Single level directory is simplest directory structure.In it all files are contained in same directory which make it easy to support and understand.
A single level directory has a significant limitation, however, when the number of files increases or when the system has more than one user. Since all the files are in the same directory, they must have the unique name . if two users call their dataset test, then the unique name rule violated.
Advantages:
Since it is a single directory, so its implementation is very easy.
If files are smaller in size, searching will faster.

Active Directory (or AD for short) is the primary resource for controlling IT resources and permissions for organizations using Windows domains. Active Directory Domain Services (AD DS) is the core component of Active Directory. It’s a data store that’s easily searchable, working as a tree and leaf system so that permissions and information flow through groups and objects down to people.
What does Active Directory Domain Services (AD DS) do?
- Stores data of users, computers, groups, and other objects (printers, shares, GPO)
- Easily searchable (global catalog)
- Offers integrated security
- Logical and hierarchical organization
- Uses a schema to define objects and attributes
- Is efficiently replicated
Most of the implementation process for Active Directory is planning. Maintenance and upkeep is the easy part. Ready to set up and maintain identity controls in network environments, including hybrid? Check out the full training here — the first week is on us! https://courses.cbt.gg/200

Hi Friends, I am Anshul Tiwari, and welcome to our youtube channel ITkFunde.
More about this video -
In this next video tutorial in our networking and infra concepts series we will learn about Active Directory.
Windows Active Directory aka windows AD is a hierarchal database where you organize, store, administer and secure your enterprise information for entities like employees, servers, printers, file directories, etc.
It is via the active directory that it's decided what all resources within your domain would be able to access each other. This starts right from when you try to login into your laptop and office network. AD authentication checks whether you are a legitimate user or not.
We will start with a real-life example to understand how an active directory works and then explore its logical and physical architecture.
There are 5 key components that make active directory logical architecture -
1. Objects
2. Domains
3. OUs
4. Tree
5. Forest
We will learn about all these components and how it's related to each other. We will also touch base on Windows AD physical architecture and how it works -
a. Domain Controller
b. Data Store
c. Schema
d. Database
By the end of this video, you will have a fair understanding of what is an active directory and how it works!
For a deep dive into advanced Active Directory concepts like installation of AD on Windows 2016 server etc, please refer to the documentation below -

#DirectoryStructure #filesystem #operatingsystemlectures
A directory is a container that is used to contain folders and file. It organizes files and folders into a hierarchical manner.
Single-level directory –
Single level directory is simplest directory structure.In it all files are contained in same directory which make it easy to support and understand.
A single level directory has a significant limitation, however, when the number of files increases or when the system has more than one user. Since all the files are in the same directory, they must have the unique name . if two users call their dataset test, then the unique name rule violated.
Advantages:
Since it is a single directory, so its implementation is very easy.
If files are smaller in size, searching will faster.
The operations like file creation, searching, deletion, updating are very easy in such a directory structure.
Disadvantages:
There may chance of name collision because two files can not have the same name.
Searching will become time taking if directory will large.
In this can not group the same type of files together.
Two-level directory –
As we have seen, a single level directory often leads to confusion of files names among different users. the solution to this problem is to create a separate directory for each user.
In the two-level directory structure, each user has there own user files directory (UFD). The UFDs has similar structures, but each lists only the files of a single user. system’s master file directory (MFD) is searches whenever a new user id=s logged in. The MFD is indexed by username or account number, and each entry points to the UFD for that user.
Advantages:
We can give full path like /User-name/directory-name/.
Different users can have same directory as well as file name.
Searching of files become more easy due to path name and user-grouping.
Disadvantages:
A user is not allowed to share files with other users.
Still it not very scalable, two files of the same type cannot be grouped together in the same user.
Tree-structured directory –
Once we have seen a two-level directory as a tree of height 2, the natural generalization is to extend the directory structure to a tree of arbitrary height.
This generalization allows the user to create there own subdirectories and to organize on their files accordingly.
A tree structure is the most common directory structure. The tree has a root directory, and every file in the system have a unique path.
Advantages:
Very generalize, since full path name can be given.
Very scalable, the probability of name collision is less.
Searching becomes very easy, we can use both absolute path as well as relative.
Disadvantages:
Every file does not fit into the hierarchical model, files may be saved into multiple directories.
We can not share files.
It is inefficient, because accessing a file may go under multiple directories.
Acyclic graph directory –
An acyclic graph is a graph with no cycle and allows to share subdirectories and files. The same file or subdirectories may be in two different directories. It is a natural generalization of the tree-structured directory.
It is used in the situation like when two programmers are working on a joint project and they need to access files. The associated files are stored in a subdirectory, separating them from other projects and files of other programmers, since they are working on a joint project so they want the subdirectories to be into their own directories. The common subdirectories should be shared. So here we use Acyclic directories.
It is the point to note that shared file is not the same as copy file . If any programmer makes some changes in the subdirectory it will reflect in both subdirectories.

In the two-level directory structure, each user has there own user files directory (UFD). The UFDs has similar structures, but each lists only the files of a single user. system’s master file directory (MFD) is searches whenever a new user id=s logged in. The MFD is indexed by username or account number, and each entry points to the UFD for that user.
Advantages:
We can give full path like /User-name/directory-name/.
Different users can have same directory as well as file name.
Searching of files become more easy due to path name and user-grouping.
Disadvantages:
A user is not allowed to share files with other users.
Still it not very scalable, two files of the same type cannot be grouped together in the same user.
Tree-structured directory –
Once we have seen a two-level directory as a tree of height 2, the natural generalization is to extend the directory structure to a tree of arbitrary height.
This generalization allows the user to create there own subdirectories and to organize on their files accordingly.
A tree structure is the most common directory structure. The tree has a root directory, and every file in the system have a unique path.
Advantages:
Very generalize, since full path name can be given.
Very scalable, the probability of name collision is less.
Searching becomes very easy, we can use both absolute path as well as relative.
Disadvantages:
Every file does not fit into the hierarchical model, files may be saved into multiple directories.
We can not share files.
It is inefficient, because accessing a file may go under multiple directories.
Acyclic graph directory –
An acyclic graph is a graph with no cycle and allows to share subdirectories and files. The same file or subdirectories may be in two different directories. It is a natural generalization of the tree-structured directory.
It is used in the situation like when two programmers are working on a joint project and they need to access files. The associated files are stored in a subdirectory, separating them from other projects and files of other programmers, since they are working on a joint project so they want the subdirectories to be into their own directories. The common subdirectories should be shared. So here we use Acyclic directories.
It is the point to note that shared file is not the same as copy file . If any programmer makes some changes in the subdirectory it will reflect in both subdirectories.
