Leaf driver refers to a device driver that accesses logically or physically existent devices on an I/O bus, and implements the functions defined for the device, such as transferring data to or from the device or accessing device registers.
Leaf devices (those requiring leaf drivers) are typical peripheral devices such as disks, tapes, network adapters, Framebuffer, and so forth. Drivers for these devices export the traditional character and block driver interfaces for use by user processes to read and write data to storage or communication devices.

Famous quotes containing the words leaf and/or driver:
“Once they came on a maple in a glade,
Standing alone with smooth arms lifted up,
And every leaf of foliage she’d worn
Laid scarlet and pale pink about her feet.”
—Robert Frost (1874–1963)
“God help the horse, and the driver too!
And the people and beasts who have never a friend!
For the driver easily might have been you,
And the horse be me by a different end!
And nobody knows how their days will cease!
And the poor, when they’re old, have little of peace!”
—James Kenneth Stephens (1882–1950)
