You are watching: What are the advantages of using loadable kernel modules?

Wcap to be ns three significant activities of one operation device with regard to secondary-storEra management?
Ins reads commands from the user or indigenous a record of commands and also executens them, usually by turning them into system calls. Ins is generally no part that ns kernetogether Because the command also interpreter ins topic come changes.
What mechanism callns need to be executed by a command also interpreter or Shell in order to start a brand-new process?
In Unix systems, a fork system contact followed by a exec system speak to should it is in performed to begin a brand-new process.

What ins the Main advantage that ns layered approach to system design? Wcap are ns disbenefits the making use of ns layered approach?
ns device ins less complicated to debuns and also modify Because alters affect just limited sections that the system fairly 보다 emotional every section that the operating system. Information is maintained only where ins ins needed and is available only within a characterized and minimal area, for this reason any type of bugs affectinns that information need to belimited to a details module or layer.

for specific devices, such as handhosted PDas and also to move telephones, a disk via a file system might not be easily accessible because that ns device. In thins situation, ns operation mechanism have to it is in save on computer in firmware.
just how could a device be design come permit a choice of operating Systems native i beg your pardon to boot? Wcap would certainly the bootstrap regime need to do?
think about a mechanism that would certainly prefer to operation both WindowsXp and three various distribution that Linux. Each operation system will be save on disk. Throughout device boot-up, a one-of-a-kind regimen (i beg your pardon we will call ns boots manager) will certainly recognize which operation device come boots into. This means that rather Originally bootinns come a operating system, ns boots manager will first run Throughout system start-up. It is this boot manager the is responsible foridentify i m sorry system come boots into. Frequently boots supervisors have to be stored in ~ particular locations the the hard disc to be known Throughout device start-up. Boots supervisors frequently carry out the user through a selection the Equipment come boot into; boot supervisors to be additionally generally draft come boot into a default operating mechanism if no alternative is schosen by the user.
the services and attributes provided through one operation device deserve to be split right into two Main categories. Briefly explain ns 2 category and comment on exactly how castle differ.
