What will the controller do before interrupting?
The controller decides whether the CPU should be immediately notified of that IRQ or not and to translate the IRQ number into an interrupt vector (i.e. a number between 0 and 255) for the CPU's table.
What is the fastest CPU Magnetic tapes and disk vedio terminal sensors mechanical controller?

How do you walk on CPU fable 3?
You need a controller.
What option interfaces with the memory controller chip to get lines of code into the CPU?
Pre-fetch - a component of the pipeline interfaces with the MCC (Memory Controller Chip) to get lines of code into the CPU
What is it called when a device requests the CPU to perform a task?
interrupt controller
Two ways that devices can gain the attention of the CPU?
1) Pressing a key on the keyboard, the keyboard controller sends an interrupt to the CPU.
Give an example of a controller that can manage a single IRQ for several devices?
CPU
What is the intermediary device between the CPU and the monitor?

What is the advantage of using a disk controller to control the hard disk?
The use of a separate disk controller frees the CPU to perform other tasks. In particular, the disk controller can manage DMA transfers, which otherwise would have to be done by the CPU. The disk controller also manages the movement of the disk head and reading or writing of the data on the disk. Again, without the disk controller, the CPU would be forced to perform these operations.
What was a CPU mouse called before it was a mouse?
A CPU
What are the two key chips or chipsets on a motherboard?
Outside of the CPU and the memory, the two main chips on the motherboard are the Northbridge and the Southbridge. Traditionally, the Northbridge contained the AGP controller, the memory controller, and the bus to the CPU. It is also connected to the Southbridge which is connected to the peripheral bus, the BIOS, the front panel, the keyboard, sound, and the hard drive controller. So functionally speaking, the Northbridge is closest to the CPU and the memory, and the Southbridge is closest to the user.
How do you interface modbus to controller and to PC?
You can do it directly from a serial port of the PC to the CPU's Modbus port (if you are using a Modicon controller). The standard used would be RS-232.
