@BlackRoseAmongThorns @daisyKutter Swap is a place on disk that gets used as a slow, temporary place to put memory when your RAM is full. Windows uses a swap file on an existing partition, while Linux generally uses a dedicated partition instead (although you can use a swap file if you really want to).
Appropriate sizes for the swap partition are hotly debated. Twice the size of your RAM if you have a small amount, or the same size as your RAM if you have lots is a good approximation.
@Lemjukes @Sunny It’s a KVM that you access over IP. It’s physically plugged into a machine’s HDMI and USB ports so, unlike software solutions, it can be used to access the BIOS/UEFI and system functions prior to hitting the desktop (like login managers and recovery consoles), and allows you to boot other operating systems and the like. It can also act as a PXE host for loading disk images, issue Wake On LAN to its connected machine, and likely a bunch of other convenience functions.
