Which bus signal line allows a device to send data directly to a computer's memory, bypassing the CPU?
DMA address. The DMA channels allow a device to send data directly to computer memory, bypassing the CPU.
How many DMA channels are available in an 8-bit system?
4. There are 4 DMA channnels available in a 8-bit system.
Which bus architecture was the first to offer configuration by software rather than by DIP switches or jumpers?
MCA was the first bus architecture to offer configuration by software rather than DIP switches or jumpers.
MCA has a bus width of___bits.
16-bit and 32-bit. The MCA bus was available in 16-bit and 32-bit bus width.
The 8-bit expansion bus contained how many interrupts and DMA channels?
8 interrupts and 4 DMA channnels. The 8-bit bus could support only 8 interrupts and 4 DMA channels.
Which buses require a software configuration program to configure their settings?
EISA, MCA, PCI, and PCMCIA buses require a software configuration program to configure their settings.
What is the maximum clock speed that an ISA Turbo bus can run reliably?
10MHz. 10MHz. is the clock speed that a ISA Turbo bus can run reliably.
What is the clock speed of EISA buses?
8MHz. Even though EISA buses were an improvement ove ISA in that they were software configurable and had a larger bus width, they still had a clock speed of 8MHz.
You have just installed a sound card in a PC and it si not functioning correctly (it produces no sound and it hangs the computer when it tries to). After checking the settings, you find that it is set to IRQ7, DMA 1, I/O port 300. You suspect that an IRQ conflict exists, so you check the other devices in the system. The system is using an ISA bus. Which device is the sound card conflicting with?(Assume the computer is using default settings for all devices.)
LPT1. LPT1 uses IRQ7 by default, which conflicts with the sound card setting.
Which bus signal line allows the CPU to send requests to the device to send data?
I/0 address. The I/O address bus signal line allows the CPU to send requests to the device to send data.
ISA has a bus width of___bits.
16. The ISA is a full 16-bit bus.
PCI has a bus width of_____bits.
32-bit and 64-bit. The PCI supports both a 32-bit and 64-bit bus width.
Which bus Signal line allows a device to request the processor's attention?
Interrupts. Interrupts are special lines that go directly to the processor, a device uses them to get the attention of the CPU when it needs to.
What is the maximum bus clock speed of the 8-bit bus?
4.77. The 8-bit bus has a maximum bus clock speed of 4.77.
PCMCIA expansion cards need which software in order to operate?
Socket Services software and Card services software.
EISA has a bus width of___bits.
32
ISA is an acronym for________.
Industry Standard Architecture
Which buses require the use of jumpers and DIP swtiches to configure their settings?
8-bit bus. Only the 8-bit buses requires the use of jumper and DIP switches to configure its settings.
PCI buses were developed mainly because__________.
Pentiums were 64-bit processors.
You have just installed a sound card in a PC and it is not functioning correctly(it produces no sound and hangs the computer when it tries to). After checking the settings, you find that it is set to IRQ7 to IRQ10, will a conflict still exist?(Assume the computer is using default settings for all devices.)
NO.IRQ10 is available to use as a sound card setting.
