In Unix-like operating systems, a loop device, vnd (vnode disk), or lofi (loop file interface) is a pseudo-device that makes a computer file accessible as a block device. Before use, a loop device must be connected to an existent file in the file system. The association provides the user with an application programming interface that allows the ...

[4] Microsoft Windows.sys files and Linux.ko files can contain loadable device drivers. The advantage of loadable device drivers is that they can be loaded only when ...
