Boot Code/ contains information about the size of the partition, volume boot code and location of the File Allocation Table 34. FAT - File Allocation Table 35. PCI/PCI-X-/PCI-E -connects to the southbridge allows 532Mb per second/ faster version allows 1.06 GB per second also is backward compatible/ has a point-to- point rather than a bus structure, connections called lanes up to 32 lanes, can carry 250 MB per second 36. SATA/PATA 37. System resource - the logical/software way to access various devices. It is a level above the hardware but intimately connected to it-as it helps the processor to locate the interface with the hardware. Data is transmitted between the processor and devices using various shared communication channels(the buses) 38. IRQ/IO Address/DMA - device that tells the processor it requires attention/ how the processor talks to the device/ how the device interacts with memory without bothering the processor 39. PnP/conflict/forced hardware - Plug-n-Play, eliminated a lot of conflicts since the system assigns its own resources to the devices/ when two devices claim the same resource/any device that you have to configure manually 40. PIO/DMA - Programmed I/O the processor micro manages data transfer/ processor delegates data transfer 41. Third-party DMA/First-part DMA/bus mastering- there is a third device, the DMA controller mediating the transfer between the hard disk and memory/the middle man is eliminated, the hard drive controllers transfer of data between itself and memory/takes control of the bus along which information is sent 42. Ultra DMA/DDR/CRC - DMA had only become te norm when Ultra DMA was introduced, gained the advantage over PIO when Ultra DMA/33 doubled the

interface transfer rate, became industry standard/ used Double Data Rate (DDR)/ Ultra DMA pushed the limit of the transfer rate thus there was more likely of an occurrence for errors thus introducing the Cyclic Redundancy Check, error detection 43. pit/land - the data is written on a CD creating pits/ lands are parts of the disc that are not pitted 44. specular/diffuse -when the lands reflect light cleanly/ when a pit spreads out the light 45.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
