Study and Comparison of Replacement Algorithms
No full textWhen a page fault occurs, the operating system has to choose a page to remove from memory to make room for the page that has to be brought in. The page replacement is done by swapping the required pages from backup storage to main memory and vice-versa. When a new page needs memory for allocation, page replacement algorithms decide which pages to swap out of the memory. In this paper, a comparison and analysis of five replacement algorithms: First in First out (FIFO), Least Recently Used (LRU), Clock, Most Recently Used algorithm (MRU), and Optimal Page Replacement (OPT) are made

Study of Origin, Geology and Geochemical Classification of the Granitoids of Imori Area, North Central Nigeria
No full textTwo distinct generations of granitiods in terms of space and time were identified in the Imori fields of north-central Nigeria. The first generation is the Older Pan-Africa calc-alkaline granite suites (OPACG) which comprise the migmatite-gneiss and the porphyritic hornblende-biotite granite. The second group is the Younger Mesozoic alkali granite suites (YMAG). This comprises rhyolite, biotite granite, and arfvedsonite granite. The OPACG suites are characterized by depletion in SiO2 ranging from 63.30 wt % - 68.38 wt % as compared to the YMAG suites which range from 70.41 wt % - 79.14 wt %. In addition, the OPACG suites are characterized by higher concentrations of MgO, fe2O3, Al2O3, TiO2, CaO, and Sr as compared to the YMAG suites. The YMAG suites are characterized by an excess of total alkaloids (Na2O +K2O), Cr, Nb, W, Ta, and lower concentrations of ferromagnesian minerals. These characteristic indicates that the OPACG suites are generated from deep-seated crustal levels rocks with the possibility of mantle materials. The YMAG suites were originated from partial melting of crustal sialic materials. Both the trace element patterns of the OPACG suites and the YMAG suites indicate that each suite is co-magmatic

Techniques of Data Deduplication for Cloud Storage: A Review
No full textWith the rapid advancement of information technology and network, it's becoming increasingly difficult to keep up, as well as the rapid expansion of data center size, energy consumption as a percentage of IT investment is increasing. As the amount of digital data grows, so does the need for greater storage space, which drives up the cost and performance of backups. Traditional backup solutions don't have any built-in protection against duplicate data being saved up. Duplicate data backups severely lengthen backup times and consume needless resources. Data deduplication is critical for removing redundant data and lowering storage costs. Data deduplication is a new technique of compressing data that helps with storage efficiency while also proving to be a more efficient technique of dealing with duplicate data. Deduplication enables a single data copy to be uploaded to storage and subsequent copies to be provided with a pointer to the original stored copy. This paper consists of an extensive literature survey and summarizes numerous storage approaches, concepts, and categories that are used in data reduplication. Also in this paper, the researchers carried out the survey for chunk-based data deduplication techniques in detail
