If you use a VPN, it can stop people, software, and web browsers from gaining access to your connection. This may be useful if you are concerned about someone obtaining control of your computer, phone, or tablet. However, be aware that it is still possible for a third party to get into your computer’s network, so learning about the VPN meaning can be essential for this purpose.
A server is a computer on the Internet connected to the Internet. There are many different types of servers. For instance, there are load balancers that can keep your computer from going to a slow speed. A web server acts like a web browser. A database server hosts a database. These are common server types that most people are familiar with.
Another type of server is an Application Server, which takes input from the computer, and sends it to a third-party application. These servers are fairly common in small businesses because they make the job of managing a computer much easier.

Types of Applications
There are numerous types of server applications available for Linux. There are web servers that you may use when you visit a web site. You can even use servers to help keep your passwords and other personal information secure. In most cases, these are automated processes that live outside the operating system that are run by the operating system.
File Servers
A file server is a server that handles all the files on your system. There are two types of file servers: shared and private.
Shared File Servers
A shared file server is a networked file server. It connects to other servers in the local network. A shared file server is very popular for creating file shares for using with programs on a remote system. For example, when you are working on a remote machine with FileZilla you can create a virtual folder on that machine and then launch FileZilla. If you were to open that folder in a browser, the contents of the virtual folder would be viewable. All you have to do is provide the IP address of the remote machine to open the share.
Private File Servers
A private file server is an isolated server on your network that is disconnected from the rest of the network. It is usually set up to create only a single folder for storing important files. This folder may be stored on a shared file server or a personal server. In Windows, Windows shares a folder to any user with appropriate privileges. In Linux, this folder is stored as a separate file system. This reduces the risk of intruders stealing data.
This is a good way to help protect your data and operating system from hackers. Many Linux distributions include a built-in file sharing feature, such as rsync.
