   1. Which chip pins are acclimated to appeal and accede a DMA transfer? 2. A DMA apprehend transfers abstracts from _________ to  _________. 3. The DMA ambassador selects the anamnesis breadth acclimated for a DMA alteration through what bus signals? 4. What is a memory-to-memory DMA transfer? 5. Describe the aftereffect on the chip and DMA ambassador back the HOLD and HLDA pins are at their argumentation 0 levels. 6. If the 8237 DMA ambassador is decoded at I/O ports 2000H -200FH, what ports are acclimated to affairs approach 1? 7. How abounding bytes can be transferred by the 8237 DMA controller? 8. Address a arrangement of instructions that transfers abstracts from anamnesis to an alien I/O accessory by application approach 3 of the 8237. The anamnesis breadth to be transferred is at breadth 20000H -20FFFH. 9. The 3 ½” deejay is accepted as a(n) __________ billowing disk. 10. A clue is disconnected into sections of abstracts alleged __________. 11. Why is NRZ recording acclimated on a deejay anamnesis system? 12. Draw the timing diagram generated to address a 1001010000 application RLL encoding 13. Why charge the active on a adamantine deejay be parked? 14. What is a WORM? 15. How abundant abstracts can be stored on a accepted DVD, an HD-DVD, and a Blu-ray DVD? 16. What are the three primary colors of light? 17. What is a pixel? 18. What 8086/8088 arresting is acclimated to baddest the administration of the abstracts flows through the 74LS245 bidirectional bus buffer? 19. How abundant time is accustomed for anamnesis admission back the 8086/8088 is operated with a 5MHz clock? 20. What are the bristles above keywords in VHDL for the bristles above argumentation functions (AND, OR, NAND, NOR, and invert)? 21. Address the software appropriate to abode a argumentation 1 on the PC7 pin of the 82C55during strobed ascribe operation.  22. How abounding ICWs are bare to affairs the 8259A back operated as a distinct adept in a system? 23. Explain how a TTL RGB adviser can affectation 16 altered colors. 24. Explain how an analog RGB adviser can affectation an absolute cardinal of colors. 25. If a video arrangement uses a vertical abundance of 60 Hz and a accumbent abundance of 32,400 Hz, how abounding raster curve are generated?
