Q1. Does linux server need to be licensed
Answer: Linux servers do not require a traditional commercial license, as Linux is licensed under the GNU General Public License (GPL). This free software license allows users the freedom to run, study, share, and modify the software without any additional fees. The GPL ensures that Linux and its derivative works remain open source and cannot be restricted by proprietary modifications. While Linux itself is free, certain applications or software used on a Linux server may require licenses, such as activation keys, node-locked licenses, or floating licenses. Therefore, while the Linux operating system does not need to be licensed, specific software running on it might.
Q2. Does linux server have a GUI
Answer: Yes, a Linux server can have a Graphical User Interface (GUI). Most Linux distributions provide both a Command Line Interface (CLI) and a GUI. There are various GUI options available, such as GNOME, KDE, XFCE, LXDE, and MATE, each catering to different user preferences and system requirements. However, installing a GUI on a Linux server is optional, as many users prefer to operate servers through the CLI for efficiency and resource management.
