A hardware 3347673Scaeldevice may be supported with a character or block 3447673Scael.Em device driver , 3547673Scaelor it may be used within the networking subsystem and have a 3647673Scael.Em network interface driver . 3747673ScaelBlock and character devices are accessed through files in the file 3847673Scaelsystem of a special type; see 3947673Scael.Xr physio 4 4047673Scaeland 4147673Scael.Xr mknod 8 . 4247673ScaelNetwork interfaces are indirectly accessed through the interprocess 4347673Scaelcommunication facilities provided by the system; see 4447673Scael.Xr socket 2 . 4547673Scael.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.
