Research Topic Identify an example of an online data source that’s used by researchers to advance their profession. Consider interstellar databases, medical data sources, and so on. Explain what kinds of data are included in the online source, the researchers who access it, and scientific advances that may have stemmed from such a resource. Be sure to cite your sources. 6). Next-fit is an allocation algorithm that starts by using the first-fit algorithm, but it keeps track of the partition that was last allocated, so that it can start its next search from that exact spot instead of restarting the search with Block 1. In other words, it starts searching from the most recently allocated block when the next job arrives. Using the following configuration with jobs arriving in order (Job A, B, C, and D) and with blocks shown in order from low-order memory to high-order memory: Job List: Job Number Job A Job B Job C Job D Memory Block List: Memory Requested Memory Block Memory Block Size 625K Block 1 250K 44K Block 2 900K 900K Block 3 280K 220K Block 4 200K Block 5 50K a. Indicate which memory blocks are allocated to each of the arriving jobs. b. Explain in your own words what advantages the next-fit algorithm could offer. 7). Worst-fit is an allocation algorithm that allocates the largest free block to a new job. It is the opposite of the best-fit algorithm. Using the following config-uration with jobs arriving in order (Job A, B, C, and D) and with blocks shown in order from low-order memory to high-order memory: Job List: Job Number Job A Job B Job C Job D Memory Block List: Memory Requested Memory Block Memory Block Size 44K Block 1 250K 220K Block 2 900K 670K Block 3 280K 64K Block 4 200K Block 5 750K a. Indicate which memory blocks are allocated to each of the arriving jobs. b. In this chapter, we introduced external and internal fragmentation. Explain in your own words, which one would be expected in a worst-fit memory allocation scheme.
