A hardware 33*47673Scaeldevice may be supported with a character or block 34*47673Scael.Em device driver , 35*47673Scaelor it may be used within the networking subsystem and have a 36*47673Scael.Em network interface driver . 37*47673ScaelBlock and character devices are accessed through files in the file 38*47673Scaelsystem of a special type; see 39*47673Scael.Xr physio 4 40*47673Scaeland 41*47673Scael.Xr mknod 8 . 42*47673ScaelNetwork interfaces are indirectly accessed through the interprocess 43*47673Scaelcommunication facilities provided by the system; see 44*47673Scael.Xr socket 2 . 45*47673Scael.Pp 4630147SmckusickA hardware device is identified to the system at configuration time 4730147Smckusickand the appropriate device or network interface driver is then compiled 4830147Smckusickinto the system.
