The operating system is a large set of programs that runs (supervises) the system and runs other system and user programs. The operating system comprises not only the memory resident kernel but also a multitude of run-time libraries, internal commands and external commands (the kind you see in /bin for example) which all need to be compatible and interact with each other. All these are written in human readable code (in C, C++, Assembler, et al) and can comprise several hundred thousand lines of code. Over several hours compilers convert all this human readable code into machine language creating a kernel that can be booted to control all the hardware. The compiled code can then be formatted into DVD media for installation purposes.
That's why the code is so large and compiling it takes a long time.
