Think of them as being special devices with constraints on them. Like
character devices for cartridge tape drives on other *ixes, which can only
read multiples of 512 bytes at multiple-of-512-byte offsets because that's
all the tape drive itself will do. (Not applicable to Linux because Linux
uses block devices and reblocks the I/O in the kernel... which has its own
drawbacks.)
