dnf install ntfs-3g
# create mount point
mkdir -p /mnt/windows/
# get the device name
sudo lsblk
# mount drive
mount -t ntfs-3g /dev/<device> /mnt/windows

Restart shell without exiting :
exec $SHELL

Now comes some explanation thanks to chatGPT:
The command exec "$SHELL" in Linux is used to replace the current shell with a new instance of the shell.
Here's a breakdown of the components:
exec: The exec command in Linux is used to replace the current running process with a new process. When exec is called, the current process is replaced by the new process, and the current shell (or program) is no longer running. This means that after running the command, the original shell or command will not be in the process list anymore.
"$SHELL": This refers to the value stored in the SHELL environment variable. The SHELL variable typically holds the path to the user's default shell, such as /bin/bash, /bin/zsh, or /usr/bin/fish, depending on your system configuration.
$SHELL would evaluate to /bin/bash.So, when you run exec "$SHELL", you're telling the system to replace the current shell process with a new instance of the same shell (as defined by the $SHELL variable).
Restarting the shell: Sometimes, you may want to restart the shell to apply changes to environment variables or configuration files (like .bashrc or .zshrc). Running exec "$SHELL" can be a quick way to do this without logging out and back in.
Resetting the environment: It can be useful for resetting the shell's environment if you've modified environment variables or paths temporarily and want to start fresh.
If you are using bash as your default shell, running:
exec "$SHELL"
Would essentially restart the bash shell in the current terminal session, and any changes to the environment or shell configuration would take effect.

The terms Assessment Year (AY) and Financial Year (FY) are often confused, but they refer to two different periods in the context of income tax in India.
Definition: The Financial Year is the period during which a person or organization earns income.
Duration: It runs from April 1 to March 31 of the next year.
Purpose: It is the year in which the income is earned or received.
For example:
Definition: The Assessment Year is the period during which the income earned in the Financial Year is assessed by the Income Tax Department.
Duration: It starts immediately after the Financial Year ends. So, it runs from April 1 to March 31 of the next year.
Purpose: It is the year in which the tax on the income earned during the Financial Year is calculated and paid.
For example:
In simple terms, the FY is the year when you earn income, and the AY is the year when you pay taxes on that income.
Nvidia display issue.
I was facing difficulty in detecting second monitor in my linux machine.
I had tried few online solutions but couldn't get it done.
Finally the solution which worked:
1.
Detect the specific VGA controller in your machine.
# lspci | grep VGA
2. Now, go to https://www.nvidia.com/en-us/drivers/ and manually search the driver inputting the specific version you obtained in step 1.
3. For example, in my case it was this file: NVIDIA-Linux-x86_64-550.135.run
4. Add executable permission
chmod +x NVIDIA-Linux-x86_64-550.135.run
5. Understand what it is:
./NVIDIA-Linux-x86_64-550.135.run --help
6.
To build and install the drivers , run the script.
( This is quite interesting file I come across, it is both a script as well as binary..need to explore more on this later )
./NVIDIA-Linux-x86_64-550.135.run
7. Boot after installation, you should be able to detect the second monitor.
