In Solaris whenever you create a new slice using format command a raw physical slice or a Raw Device will be created which is addressed as /dev/rdsk/c#d#s# where # is the number for slice.
After formatting it with newfs command the slice will be addressed as /dev/dsk/c#d#s# which can now be used for mounting.
eg. newfs /dev/rdsk/c0d0s4
mkdir /oracle
mount /dev/dsk/c0d0s4 /oracle
After mounting /dev/dsk/c#d#s# is called as Block Device
/dev actually contains logical device names which are links (Shortcuts in windows terminology) to actual physical devices in /devices directory.

The brand's initial processors were very similar to the earlier CPUs branded Pentium II. The most notable difference was the addition of the SSE instruction set (to accelerate media processing and 3D graphics)

In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

Also

Baseband Signalling:

1)Uses digital signalling

2)No frequency-division multiplexing

3)Bi-directional transmission

4)Signal travels over short distances

Broadband Signalling:

1)Uses analog signalling

2)Unidirectional transmission

3)Frequency-division multiplexing is possible

4)Signal can travel over long distances before being attenuated
