2. The floppy drive uses which DMA (direct memory access) channel?

A 5 B 4 C 1 D 2 Free MCQs www.sharemcq.com     Answer: Option D Explanation: DMA channels are used by high speed devices and they allow them to communicate directly with the main memory (RAM) on our system. When DMA channels are used, CPU is not involved in the communication. Communication without the CPU is a benefit since CPU is busy with all sorts of different processing tasks. Sometimes we don’t want to wait the CPU, so we enable other devices on the system to access RAM directly. DMA channels can be used by sound cards, hard disk drives, CD/DVD-ROM drives, tape drives, etc. By default, only one DMA channel can be assigned to one device on the system. If devices share the same DMA channel, memory errors can occur. For example, Floppy disk controller is assigned to DMA channel 2. Channel 1 is assigned to sound card. Channels 3, 4, 5, 6, and 7 are usually available to be assigned by other devices on the system. Since DMA channel 0 is used to cascade two DMA chips, it is not assigned to devices..

10. What is the most significant difference between the USB and IEEE1394 standards?

A IEEE 1394 is faster B USB does not support USB C USB is plug and play D IEEE 1394 is hot swappable Free MCQs www.sharemcq.com     Answer: Option A Explanation: FireWire and USB are technologies used to connect devices to a computer and transfer data quickly. FireWire is also known by the term IEEE 1394 High Performance Serial Bus, and USB stands for Universal Serial Bus. The main difference between the two is that FireWire is made to handle more data than USB, particularly audio and visual information. For example, a 2.0 USB can handle a data transfer rate of 480 Mbps, whereas an 800 FireWire can take on 800 Mbps. However, a 2.0 USB can manage 127 devices while an 800 FireWire can only manage up to 63 devices. Both work using the plug-and-play, hot-pluggable technology, meaning you can plug a device into your computer while the computer is on, and the computer will recognized it and start to communicate with it. view details Workspace View Answer Workspace
