logical cache is what computer companies call L1, L2, and L3 cache.
It is smart memory on the chip or processor that remembers what the processor has ask for the last 10 to 100 processes.

What is meant by distributed cache?
A distributed cache is when a cache is distributed across an array of ISA server computers. It is set up as a single logical entity which prevents duplication and also increases efficiency.

What is write-through in memory caches?
When a datum is written to the cache, it must at some point be written to the backing store as well. The timing of this write is controlled by what is known as the write policy. In a write-through cache, every write to the cache causes a write to the backing store. Alternatively, in a write-back cache, writes are not immediately mirrored to the store. Instead, the cache tracks which of its locations have been written over (these locations are marked dirty). The data in these locations is written back to the backing store when those data are evicted from the cache. For this reason, a miss in a write-back cache will often require two memory accesses to service: one to retrieve the needed datum, and one to write replaced data from the cache to the store.The preceding information was obtained from the related link at the left.Write Back - Data is written first to the cache, then to the logical drive for better performance. The Promise VTrak has a cache backup battery to protect data in the cache from a sudden power failure.Write Thru - Also written as "Write Through". Data is written to the cache and the logical drive at the same time for safer operation. No battery backup is needed since data is written to the drives immediately.
Differences between physical addressing and logical addressing?
In computer architectures, a logical address is the address at which a memory location appears to reside from the perspective of an executing application program. This may be different from the physical address due to the operation of a memory management unit (MMU) between the CPU and the memory bus. Physical memory may be mapped to different logical addresses for various purposes. For example, the same physical memory may appear at two logical addresses and if accessed by the program at one address, data will pass through the processor cache whereas if it is accessed at the other address, it will bypass the cache.
