What else can I help you with?
Why are all your devices using one IRQ in Win2k or WinXP?
Windows 2000 and on used IRQ sharing because the OS would allow more and more hardware. There is a set number of IRQs (15 or 16).
What 2 IRQ's could you assign to a NIC without causing a conflict with preassigned devices?
To avoid conflicts with preassigned devices, you could typically assign IRQs 10 and 11 to a Network Interface Card (NIC). These IRQs are often available for use in modern systems, as many standard devices are assigned IRQs 1 through 9 or 12 through 15. However, it's always best to check the specific hardware configuration and the system's IRQ routing table to ensure there are no conflicts.
How many IRQs does the typical device use?
2
What are three irqs that commonly used for network adapter?
Jkkkkkk
What is IRQ 3 used for?
IRQs 3 is reserved for the COM1 port.
What do we mean by hardware computer?
Hardware computers are physical devices that you can touch and feel. This is perhaps the opposite of a Virtual Machine (VM), which does all the things a hardware computer can do, but it “lives” inside a hardware computer. Many VMs can be hosted on a hardware computer, although the total number that can run in a hardware computer depends on resource utilization and availability (e.g., hard drives, RAM, network adapters, etc.).
What type of computer resources are direct lines to the processor and used by computer componets to request attention from the CPU?
Interrupt Requests are method for handling requests from components such as Keyboard, Mouse, Clock etc & get attention of Processor.Each specific components is assigned IRQ number.
What is a List PC's system resource types?
Its A IRQs , I/O addressses, memory addresses, and the MDA channels
What is Hardware random number generator?
In computing, a hardware random number generator is an apparatus that generates random numbers from a physical process.
How can one contact the Australian company Total Tools?
Total Tools is a franchise in Australia that specializes in selling tools and hardware. To contact them, one can fill out a form online at Total Tools, or use their store locator feature to get the phone number of a local branch.
Which direct memory access channel is used for the floppy controller?
From http://www.brainbell.com/tutors/A+/Hardware/Direct_Memory_Access_DMA.htm "DMA channels use the same rules as IRQs. Just as with the 8259 chip, DMA availability soon became a problem because an insufficient number of channels was available. A second DMA chip was added for 286-based computers. Just like the second IRQ chip, these two are cascaded, allowing a total of eight DMA channel assignments (usually referred to simply as DMA channels). The floppy disk drives on all computers use DMA channel 2."
What does IRQ stand for?
Abbreviation of interrupt request line, and pronounced I-R-Q. IRQs are hardware lines over which devices can send interrupt signals to the microprocessor. When you add a new device to a PC, you sometimes need to set its IRQ number by setting a DIP switch. This specifies which interrupt line the device may use. IRQ conflicts used to be a common problem when adding expansion boards, but the Plug-and-Play specification has removed this headache in most cases.see: http://www.webopedia.com/TERM/I/IRQ.html
