How are multiple interrupts dealt with?
There are 2 approaches to handle this situation,
1.Disable interrupts while an interrupt is being processing
in this approach, when the processor is being processing an interrupt, the processor ignores any new interrupt signal and these new signals have to wait in a queue and processor will check after the currently processing interrupt is finished.
2. Defining priorities for interrupts
in this case, each interrupt has a priority value. When the processor is being executing an interrupt, another interrupt can interrupt and gain the processor if the second interrupt has a higher priority than first one

Which is the best operating system for gaming?
Although rumors say Windows Vista is terrible for gaming, I have found Windows Vista Ultimate 64-bit Edition to be good at gaming. Recent games like Crysis perform well in this OS. However, old games like Starcraft and Red Alert II are very hard to use on it. Macintosh offers a good OS, but with a mac you have alot of compatibility issues with Windows and there are limitations to games you can play on the system. If I remember correctly, a 64-bit OS can hold up to 32gb of ram. However I am certain that Macintosh can hold up to 32 gb of ram.
A port is a place through which a peripheral device attaches to a computer so that data can be exchanged between it and the operating system.
Peripherals devices can be attached to a computer in several ways (depending on the age of the computer:
- An RS-232 serial port connection
- A parallel printer port can supply two way control and communication with a device
- A usb capaable device can be connected to a usb connector.
- A firewire port
- A device adapter card can be plugged into an available compatible slot to support additional devices.
- SCSI devices can be attached via a compatible SCSI adapter.
- An eSATA (external Serial ATA) device can support SATA devices.
- A wireless or wired network adapter can be used with networked devices
- An HDMI (High-Definition Multimedia Interface) connector can support various communication devices besides audio and video output.

my computer in xp
vista has something called "Computer" that may be short for "Bill's computer"
7 and 8 are a bit worse
once you run "computer" as administrator you can view hidden files by setting viewing privileges
but the vista and later introduced a file attribute "Ownership" that is set to many files that used to be available and only the SYSTEM can see.
so if you have an older program and some options to set and they are saved in superpaint.INI *.ini files are system owned and cant be changed or erased once they are written ...
there are even directorys like this
"documents and settings" contains
my files my pictures my favorites etc and can only be viewed by system and seen by registered system applications
there are several addons for windows out there that allow you to "Take ownership" so you may uses some windows programs to view or edit files
and superpaint.INI will then be able to be modified by superpaint or notepad

spooling stands for simultaneous peripheral operation on- line. it is a mechanism to deal with following issue:-
a) to reduce the speed mismatch between slow input / output devices and CPU for better utilisation of the CPU.
b) to convert manually exclusive I/O device into non mutually exclusive I/O devices so that they can be simultaneously used by multiple processes in multiprogramming system.
Can you install Mac OS X Snow Leopard from a used disk?
If it's the original disk (grey?) that came with yourcomputer when it was brand new then yes.
If it's a retail disk, then if your computer meets the minimum system requirement then yes.
If your computer came installed with Lion brand new then it might, but it's not supported by Apple. If Apple had not updated the new computers when Lion started being shipped then you still have the older architecture so you could still boot to an older OS, at least as far as the OS that those computers originally came with.
In other words, when Apple ships a new OS and dosen't update the computers at the same time the computers will only ship with the new OS from then on.
