Bob,
In Unix everything is a file... regular files, links, directories as well as
the block and character special devices. These entities you are seeing have a
specific purpose to keep the Unix Operating system functioning.
Now, the /bin/ls binary has functionality that allows colorization based upon
file type, and other factors. Yes, like you, I typically work in listings that
are black and white for ease of viewing.
The block device for /dev/sdb is used by a driver in the kernel to access that
disk drive. /dev/sdb1, for example, would be the first partition on that disk
drive, etc...
Why are you worried about these?
