Which coordinate in the equatorial coordinate system is like longitude in the geographical coordinate system?
a coordinate system is lines of longuitude and latitude that are used in a map to locate something. There is a coordiante in the Equatorial Coordinate System that is like longitude in the Geographical Coordinate System.....what is the coordinate? Celestial Equator?
What is the meaning of coordinate index?
Coordinate index ? Sure ! It's easy ... You just have to coordinate your index number !
what is y-coordinate in rectangular coordinate system?
A point's y coordinate is its vertical position, or how high or low it is.
What is coordinate plane or coordinate system?
graphing tool
What is two-coordinate graph?
a two coordinate graph is a graph
HOW DOES CPU INTERFACE WITH THE DEVICE TO COORDINATE THE TRANSFER?

How Memory interface with CPU indicate the direction of signal and control signals?
How Memory interface with CPU indicate the direction of signal and control signals?
Difference between programmed IO and interrupt IO?
1.Programmed IO is the process of IO instruction written in computer program , where Interrupt Initiated IO is done by using interrupt and some special command. 2.The advantage of Interrupt Initiated IO is ,it is a time consuming process than Programmed IO. 3.In Programmed IO technique to transfer data,required constant motoring on peripheral by CPU,once data transfer is initiated, CPU have to wait for next transfer. In Interrupt Initiated IO once data transfer initiated ,CPU execute next program without wasting time and the interface keep monitoring the device. When the interface determines that the device is ready to transfer data, it generate an interrupt request,CPU stop the current task,execute the transferring process,and then return to the previous on-processing task.
What is the interface between CPU and peripherals called?
A serial bus.
How do you transfer old CPU files to new CPU?
You don't. The CPU is your processor. You can transfer files to a new HDD, one of the easiest ways is to slave up your old drive and copy everything over.
What is a bus interface unit?
The bus interface unit is the part of the processor that interfaces with the rest of the PC. Its name comes from the fact that it deals with moving information over the processor data bus, the primary conduit for the transfer of information to and from the CPU. The bus interface unit is responsible for responding to all signals that go to the processor, and generating all signals that go from the processor to other parts of the system.
What is used to coordinate the storage and transfer of email between users on a network?
The Simple Mail Transfer Protocol is used to coordinate the storage and transfer of email between users on a network. Other internet protocols include HTTP and FTP.
What interface has data transfer rates up to 640 MBps?
Small Computer System Interface (SCSI)
Is ide and dma the same thing?
No, IDE stands for Integrated Drive Electronics A hardware interface widely used to connect hard disks, optical discs and tape drives to a PC. Introduced in 1986 with 20MB of storage, capacities increased a thousandfold in less than two decades. Compared to the SCSI interface, IDE has been the more economical choice. (Direct Memory Access) Specialized circuitry or a dedicated microprocessor that transfers data from memory to memory without using the CPU. Although DMA may periodically steal cycles from the CPU, data are transferred much faster than using the CPU for every byte of transfer. On PCs, there are eight DMA channels commonly used as follows. Most sound cards are set to use DMA channel 1. See PIO mode. DMA Used for 0 8-bit transfer 1 8-bit transfer 2 Floppy disk controller 3 8-bit transfer 4 Cascaded from 0-3 5 16-bit transfer 6 16-bit transfer 7 16-bit transfer DMA Disk Transfers There are various modes of data transfer on IDE disk drives. The PIO modes use the CPU, and the DMA modes bypass the CPU.
Why Direct memory access has priority over the CPU when both request a memory transfer?
we can transfer data direct to and from memory without the need of the CPU. The transfer of data between a fast storage device such as magnetic disk and memory is often limited by the speed of the CPU. Removing the CPU from the path and letting the peripheral device manager the memory buses directly would improve the speed of transfer. This transfer technique is called direct memory access(DMA). During DMA transfer, the CPU is idle and has no control of the memory buses. A DMA controller takes over the buses to manage the transfer directly between the I/O device and memory. With Regards.

3 types of DMA transfer modes?
· Block transfer DMA controller takes the bus control by CPU. CPU has no access to bus until the transfer is complete. During this time CPU can perform internal operations that do not need bus. This is a common and popular method with modern microprocessors. · Cycle stealing This is a word-by-word transfer based on CPU cycle stealing. When DMA steals a cycle, CPU is stopped completely for one cycle. Cycle stealing is not an interrupt. CPU pauses for just one machine cycle. This type of transfer takes a period of time. Some major steps of DMA cycle stealing in order to transfer data to and form memory are: · DMA needs control of the CPU · DMA must use the bus only when the CPU does not need it · CPU is suspended by DMA just before it needs to use the bus · CPU pauses for one bus cycle · DMA transfers one words and then returns the control to CPU · The overall effect is to cause the CPU to execute more slowly · Interleaved DMA. It is similar to block transfer technique, here DMA controller takes the control of system bus only when CPU is not using it. For example, performing an ALU operation or incrementing a counter. The data transfer by this kind of method takes a period of time.
What is the rate of transfer between the processor and motherboard components?
