The correct answer is: D. All of the above
A special boot disk is required for installations that cannot be installed using the standard installation method. This includes installations that are performed over a network (NFS or FTP), installations that are performed on a computer with a PCMCIA card, and installations that are performed on a computer with a special type of BIOS.
NFS (Network File System) is a distributed file system protocol that allows a computer to access files that are stored on another computer over a network. FTP (File Transfer Protocol) is a standard network protocol that allows files to be transferred between computers. PCMCIA (Personal Computer Memory Card International Association) is a standard for expansion cards that are used in laptops. BIOS (Basic Input/Output System) is a small program that is stored on a computer’s motherboard and is responsible for initializing the computer’s hardware and loading the operating system.
If you are not sure what type of installation you need to perform, you should consult the documentation for your computer or operating system.
