it means mapping directly
direct mapping doesn't need replacement algorithm
A mapping diagram can be used to represent a function or a relation true or false?
A function is a relation whose mapping is a bijection.
No. There is no mapping.No. There is no mapping.No. There is no mapping.No. There is no mapping.

It is simply a mapping. It could be a function but there are several conditions that need to be met before the mapping can become a function and there is no basis for assuming that those conditions are met.

If, at any time, a vertical line intersects the graph of a relationship (or mapping) more than once, the relationship is not a function. (It is a one-to-many mapping and so cannot be a function.)
Advantage: Direct mapping is simple and requires less hardware, making it cost-effective. It also provides fast access to data due to its fixed mapping of blocks to cache lines. Disadvantage: Direct mapping can lead to cache conflicts, where multiple memory blocks map to the same cache line, causing performance degradation. It also has poor cache utilization compared to other mapping techniques.
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
