Okay now that you've mentioned it, I went to grub, selected "advanced options Well what's up with this big list up there? Can you explain? Where the versions in your advance menu 3.
It will probably be listing the latest version of each. As Ross says, you can delete them if you want. They don't take up all that much space and so I would always keep the last 3 or 4 kernels as a fallback. I'm guessing that 3. If you don't like them being on your system, they can be removed with: sudo apt-get autoremove Which should clear out the unused kernels along with other unused packages.

The Linux kernel: The core of the OS. User processes: These are the running programs that the kernel manages. User processes are what collectively make up user space. User processes are also known as just processes.
This system uses the Mach kernel. The Mach kernel is an example of a microkernel. This information may now answer the popular question - "Is Android a Linux system?
Android also uses a modified Linux kernel. Yes, there are different Linux kernels, but they are all still Linux. By the way, MeeGo is also Linux. What does the "G" stand for in "GNU"?
Now, remember, I said there are different Linux kernels. All Linux kernels have come from the Vanilla kernel directly or indirectly. The Vanilla kernel is the Linux kernel that can be downloaded from Kernel. The Vanilla kernel is the mainstream, official kernel that is made and managed by Linus Torvalds.
RTLinux is a real-time microkernel from of Vanilla. Yes, not all Linux kernels are monolithic, but most are monolithic. Firefox-OS is a mobile operating system that uses the Gonk kernel which contains various needed drivers modules for mobile devices like phones. Gonk also has enhancements for the system's software. Sony also has a special Linux kernel for their Playstation. Linux-libre is a Linux kernel that completely lacks proprietary code and modules.
Basically, it is the Vanilla Kernel with code removed. This is perfect for people that want to avoid all proprietary software. Beware, some device will not work with this kernel. CoLinux is a specialized kernel that was modified to allow Linux to run with Windows at the same time.
The L4Linux kernel is designed to run on the L4 microkernel. This is a combination of Google's changes and code with L4Linux. Rather, the source code itself was greatly changed.
