What is the difference between hibernate and suspend in Linux?
Hibernate is a state of the operating system where all data, including the state of open applications and unsaved user data, is written to the hard disk before powering off. Upon powering back on, the system is restored to its previous state. This can save time in the event of system crashes and random reboots, as the user can quickly return to what they were working on.
Suspend on the other hand, allows the operating system to go into a low power state where all active processes and user data are stored in RAM and the system powers off. This can be used to conserve power and is less prone to data loss than hibernate, as long as the system has enough power to remain in suspend mode. However, when powering on, the user must start from where they left off as opposed to returning to the previous state with hibernate.

How to share files between windows and Linux?
1. FTP File Transfer: Transferring files between two different operating systems can be done by using FTP (File Transfer Protocol) software such as Filezilla. With FTP, you can connect to a server (in this case one of the machines must act as a server) and then upload and download files as you like.
2. Mounting a Windows Share: If your Windows machine has a shared folder, you can mount this folder as a local folder on your Linux PC. By doing so, the files in the shared folder will be accessible from the Linux machine as if those files were located on the Linux PC itself.
3. Setup Samba File Sharing: Samba is an open source software suite which is available for Linux and Windows computers. It allows you to setting up a shared folder with ease where Windows and Linux files can be shared with each other seamlessly.
4. Using Virtual Machines: Setting up a virtual machine can be an easy way to quickly transfer files between different operating systems. This can be done by simply setting up a virtual machine on one of the machines, copying the files from the machine to the virtual machine, and then copying the files from the virtual machine to the other machine.
5. Cloud Storage: The last option is to use a cloud storage provider such as Google Drive or Dropbox which can be used to store files in the cloud and accessed by both Windows and Linux PCs.

How to connect a Linux desktop to a remote server?
1. Establish a secure connection: Secure connections can be established using SSH, a secure user authentication protocol. Make sure both computers are connected to the same network and you have access to the remote server. You can then open a terminal window on your Linux desktop and use the ssh command to connect to the remote server. For example, if the IP address of the remote server is 192.168.1.130, you can type ssh [email protected] in the terminal window to initiate the connection.
2. Log into the remote server: Once connected, you will be asked to provide the username and password (if applicable) of the remote server.
3. Copy files: You can copy files from your Linux desktop to the remote server using the scp command. For example, scp <path of local file> <username>@<remote_server_IP>:<path of remote directory>.
4. Execute remote commands: You can execute remote commands on the remote server using the ssh command itself. For example, ssh [email protected]<remote_server_IP> <command>.
You can also use FTP or SFTP to transfer files between your Linux desktop and the remote server.
