NFS
NFS (Network File System) is a way for computers to share files and folders over a network, kind of like a shared drive in an office. When someone mentions NFS in their resume, they're typically talking about setting up and managing these shared storage spaces in business environments. It's particularly important in cloud computing and data centers where many servers need to access the same files. Think of it like a digital filing cabinet that multiple computers can access at once. This technology has been around for decades and is still widely used, especially in Linux and Unix environments.
