Probably Gary Kildal, he wrote CP/M to help himself develop the PL/M compiler for Intel. He offered to give CP/M to them too, but they didn't want it "we make chips not computers". So he left and started his own company. Eventually Intel realized they did need an OS and developed ISIS (but thats a different story).
Two types of OS available one is client or desktop OS and the other is network OS. Desktop OS is the OS which can be used in a standalone computer but in case of network OS a group of computer can use it. Example: Desktop OS : Window xp,7 Network OS : Unix, Linux, Solaris - SuresH
OS is stored bydefault in C: drive of Your computer
You can install a server OS on it.
If the computer's OS is windows enabled, the "desktop". Otherwise the command line terminal.
windows vista
In terminal: sudo apt clean

Your question is very vague. Most laptops are capable of running the same operating systems as a desktop computer.
Palm Desktop is a personal information manager computer program for Microsoft Windows or Mac OS X and can be used alone or in combination with a Palm OS personal digital assistant. Palm Desktop can be purchased on CNET, Hot Sync 410, and Palm Desktop.
Right-click you mouse on the desktop, and, depending on your OS and version of OS, look for an option for changing the appearance of your desktop. You should find a 'Browse' -button which will allow you to select the image you want.
A desktop uses the same OS as any other computer, Windows, Mac OS, or Linux. Also, I'd recommend Mac OS X if you're getting a new computer. Here's the scoop: if the computer has an  on it, it runs Mac OS. If not, it runs Windows or Linux.
