Mapping
Mapping is the process of creating visual representations of spatial relationships or data, while cartography specifically refers to the art and science of making maps. Cartography involves designing maps with attention to aesthetics, symbols, and data presentation techniques, whereas mapping can refer to a broad range of spatial data creation and analysis methods beyond traditional cartographic practices.
Conventional mapping involves manually surveying and creating maps using physical tools like paper, pencils, and measuring devices. Digital mapping, on the other hand, uses digital technology to create, store, and analyze spatial data, allowing for more detailed and interactive maps that can be accessed and shared easily online.
Well, information mapping is when you look up and find new information and put it in a form of text e.g map whilst mind mapping is when you write the information you already know in a form of text.
A function is a relation whose mapping is a bijection.

Direct mappingA given Main Memory block can be mapped to one and only one Cache Memory line.It is Simple, Inexpensive, fastIt lacks mapping flexibilityAssociative mappingA block in the Main Memory can be mapped to any line in the Cache Memory available (not already occupied)It is slow, expensiveIt has mapping flexibility

it means mapping directly
Mercator projection distorts the size of land masses, resulting in high distortion near the poles. Equal area projections maintain accurate land area proportions, making them useful for representing data like population density.
genetic mapping is the mapping of genes to locations within a genome.
The differences among direct mapping and set-associative mapping :Direct mapping : Each line in main memory maps onto a single cache line.Set-associative : Each line in main memory maps onto a small (collection) set of cache line.Direct mapping : A memory block is mapped into a unique cache line, depending on the memory address of the respective block.Set-associative : A memory block is mapped into any of the line of a set. The set is determined by the memory address, but the line inside the set can be any one.dont knowyet
