what are cpu device
The CPU has its own internal bus for communication the internal cache
Every input device attached to the motherboard bus lines has a direct line of communication with the CPU. These lines are known as interrupt request lines (IRQs) which can be prioritised. By signalling the CPU that an input is pending, the CPU can alert the operating system to deal with the request, which will then be prioritised accordingly.
Yes, the CPU itself is a processing device, it is the "brain" of the computer. CPU = Central *Processing* Unit
CPU is not a peripheral device.
No. A CPU is hardware.
No, the CPU is the Central Processing Unit. A monitor or printer would be an example of an output device.
Peripheral devices are connected and logged to the CPU through interfaces like USB, SATA, or PCIe, which facilitate communication between the device and the processor. When a peripheral is connected, the operating system detects it using device drivers that manage data transfer and functionality. The CPU then communicates with the device through memory-mapped I/O or direct I/O, allowing the system to recognize and interact with the peripheral efficiently.
when an i/o device is ready to do the process with cpu and the cpu not is not know the status of.. trhe i/o device,then i/o device sends a request to service it
No. It is a CPU.
