There is no "default" Unix shell. Different Unix vendors shipped different shells.
They are both UNIX shells, that is some kind of old DOS environments on older PCs, but just doing similar things in UNIX. Both provide opportunities for scripting and doing other admin work in the UNIX environment. They differ slightly, and basically are about the same thing wrapped in different vendors presentations- if memory serves me well, Korn comes with Sun/Solaris ...and is supposed to be more up to date. Provided with Linux (which is quite like Unix) is the Bash shell which is derived from the Bourne shell and is a superset of it. See the link below for some more information.

A shell is a "command prompt" like application in unix based systems, there are many shells, k-shell (ksh) is one of them, others are bourne-shell (sh), born again shell (bash) etc .... They have their own set of commands, some of them may be supported by more than one shell. states above are correct k-shell or korn shell.
The first shell was 'sh', the Bourne Shell
A Unix shell can be obtained in Cygwin, a Unix compatibility layer used to compile Unix programs and run them on Windows. Microsoft also makes a shell known as "Windows PowerShell" which incorporates more Unix-like features than the standard command prompt.
The a default Unix shell is the shell that comes with and is activated initially with your distribution of Unix. The shell is essentially the program the runs the command line interface allowing someone to interact with their computer. Some examples are the Bourne-Again shell (bash) or the Bourne shell (sh).
