Linux device drivers...



A block device is normally associated with file structured devices such 
as disks. Character devices are normally serial devices such as 
terminals. You can to an ls -l on /dev, and look at what devices are

corresponding character device (normally called the raw device. The pipe 
device is normally associated with the FIFO, and you need not be 
concerned about that.
