A Web cache is a temporary memory in your browser where temporary information about the web site you are visiting are stored. Information like login id, password, previous history of pages you visited etc would be stored in the cache...
A cache is intended to speed things up. The larger the cache, the slower it performs. If it becomes slower to access the cache than the memory itself, it defeats the purpose of having a cache.
L3 cache
Browser Cache
cache is more expensive and it will increase the cost of the system terribly. processing of more than one cache will complicate the design of CPU and increase the burden on CPU.
By way of an internal L1 Cache
This hard drive has a 100Gb internal cache.
Internal Cache
Not the same.
The first Intel CPU to feature external cache was the Intel Pentium Pro. External cache is also referred to as L2 cache, while internal cache is called L1 cache.
Back-Side Bus
Internal cache is stored in a reserved area of the RAM of your computer. External cache is also called secondary cache or level 2 cache memory. It is external to the microprocessor and is stored on a separate chip.
Basically for the same reason that cache itself helps increase the speed. If there is more cache memory, the computer will have more information readily available, and there will be less cases where the information CAN'T be found in cache, and the CPU needs to access actual RAM, which is slower (or whatever other source of data the cache is supposed to speed up).
Back-side
The CPU has its own internal bus for communication the internal cache
Answer: True
back-side bus (BSB)
