What types of operations is DMA used to accelerate?
DMA operations
The Point of Concurrency of the Angle Bisectors of a Triangle?
The point of concurrency is the point intersection.
Is it true that the point of concurrency of any triangle only happens inside the triangle?
Depends on the point of concurrency of what. The point of concurrency of altitudes will be outside in any obtuse triangle.
What is a wrong-way concurrency?
A wrong-way concurrency is a road concurrency in the United States in which two numbered highway routes are signed in opposite, conflicting directions on the same stretch of roadway.
Is a circumcenter a point of concurrency?
Yes. Every point in the Cartesian plane is a point of concurrency for some set of lines.
Which parallel port uses a dma channel?
ECP was designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
How would you define concurrency and recovery?
Concurrency is when computer science and the system works together. Recovery is taking the time to heal.
Which parallel port standard uses a DMA channel?
Extended Capabilities Port (ECP) as designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
Is it possible to use a dma controller if the system does not supports the interrupts?
You'd have to use DMA with polling, and thats usually not supported
What is concurrency in Unix?
the unix is a form of group in operating system
What are the disadvantages of using DMA?
Direct Memory Access (DMA) can introduce some disadvantages, including increased complexity in system design, as it requires additional hardware support and careful management of memory access. It can also lead to potential data inconsistencies if multiple devices attempt to access the same memory location simultaneously. Furthermore, using DMA may increase the risk of system latency during the initial setup or configuration phase, as the CPU has to manage DMA channel allocation and transfer requests. Lastly, debugging DMA-related issues can be more challenging compared to traditional CPU-controlled data transfers.
While looking around in the bios settings kaitlin set the pio and the dma settings to auto will this affect the system in any way explain?
pio and dma settings will not affect the system in any way.
Differentiate Optimistic concurrency control and pessimistic concurrency control?
concurrency control algorithm
What is busmastering?
bus mastering is a feature supported by many bus architectures that enables a device connected to the bus to initiate transactions. Also called "First-party DMA", to contrast it with Third-party DMA, the situation where the system DMA controller is actually doing the transfer.
What is the advantage of DMA transfer?
DMA allows devices to communicate with each other directly, instead of relying on the CPU to manage the transfers. This frees the CPU up to do other tasks, and increases system performance.
Are DMA channels part of a system resource?
Formally no, since 'resource' refers to something consumable, like RAM or CPU time. Rather, DMA channels are encountered to be a part of hardware infrastructure.
Why DMA is used?
DMA, or Direct Memory Access, is used to enable peripherals to transfer data directly to and from system memory without involving the CPU. This reduces the processing load on the CPU, allowing it to perform other tasks while data transfers occur in the background. DMA is particularly beneficial for high-speed data transfers, such as in audio and video processing, where efficiency and speed are crucial. By streamlining data transfer, DMA enhances overall system performance and responsiveness.
