Direct mapping
A given Main Memory block can be mapped to one and only one Cache Memory line.
It is Simple, Inexpensive, fast
It lacks mapping flexibility
Associative mapping
A block in the Main Memory can be mapped to any line in the Cache Memory available (not already occupied)
It is slow, expensive
It has mapping flexibility
Direct Conflict Management is to figure it out or avoidance. Indirect Conflict Management is it seems to appeal a common goal. The difference between direct and indirect conflict management is direct conflict management is to figure it out or avoidance, and indirect conflict management is to appeal a common goal.
An indirect free kick must be touched by another player before it goes into the net to count as a goal. A direct free kick does not.

A direct victim is the actual victim of a situation. If a man is beating his wife, she is the direct victim.

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

Three types of mapping procedures are there? (1) Associative Mapping-The fastest and most flexible cache organizations uses associative mapping. The associative memory stores both the address and content of memory word. This permits any location in catche to store word in main memory. (2) Direct Mapping-Associative memories are expesive compared to RAM's because of added logic associated with each cell. (3) Set Associative Mapping-It is a more general method that includes pure associative and direct mapping as special case. It is an improvement over the direct mapping organization in that each word of cache can store two or more words of memory under the same index address. Each data word is stored together with its tag and the number of tag data items in one word of cache is said to form a set. With Regards Veer Thakur Chandigarh
I didn't quite understand your question but I'll answer you anyways :P.. It's known that the main memory is much larger that the cache memory , and we need to transfer a block of instructions to the cache memory to be frequently used by the processor to improve performance and reduce time spent in fetching instructions or data ( dealing with cache memory is much faster than RAM ). for example lets say that a main memory has a 128 data blocks and you need to place them in the cache memory which consists of 32 data blocks? then you have to have sort of technique to place them or MAPPING FUNCTION. And there are plenty of 'em (four mapping techniques as far as i know) i will just mention them without getting into details: Direct mapping , fully-associative, set-associative and n-way set associative. if you need more details just ask. greetings Can you please provide some help over Direct mapping , fully-associative, set-associative and n-way set associative Thanx

Geographers use a variety of research methods, including fieldwork, remote sensing, GIS (Geographic Information Systems), cartography, surveys, interviews, case studies, archival research, and statistical analysis. These methods help geographers collect, analyze, and interpret spatial data to better understand patterns and processes in the natural and human environment.

Some websites that offer a cycle route mapping tool are MapMyRide, Bike Route Toaster, Bikehike, Google Maps, Bikely, Transport Direct, Ride With GPS and Map My Route.
The direct object is the noun or pronoun that receives the action of the verb directly. An object, on the other hand, is a more general term that refers to any noun or pronoun that receives the action of a verb, including direct and indirect objects.
