Cache is a special type of memory which is quicker to access. stuff you have recently used will go to your cache so when you perform a function you have just performed it will happen quicker. 4MB is a large cache. Level two Cache is a special memory type that is faster than Lv1 Cache, it is like RAM but it is used by the CPU as a fuction Storage to make that process faster.

∙ 11y agoLevel 2 cache, also called secondary cache, is a memory that is used to store recently accessed information. The goal of having the level 2 cache is to reduce data access time in cases when the same data was already accessed before. In modern microprocessors that incorporate data prefetching feature the level 2 cache may also be used to buffer program instructions and data that the processor is about to request from memory. This also reduces data access time. Please note that the level 2 cache is secondary to the CPU - it is not as fast as the level 1 cache, although it is usually much larger. All data that is requested from level 2 cache is copied to level 1 cache. Requested data stays in the secondary cache if it's an inclusive cache, and is removed from secondary cache if it's an exclusive cache. Secondary cache is usually unified, i.e. it is used to store both program instructions and program data.

∙ 14y agoL2 cache is a fast memory store located between the local bus (processor pins) and main memory. Based on a most-recently-used algorithm, it increases processor performance by keeping a copy of recently used memory, based on the probability that it will tend to be used again. The cache interface also reads from memory ahead of the processor's demand, so that, by the time the processor is ready to request a certain memory value, it might already be in cache, and the processor does not have to wait for it to be fetched.

Can you name the two cache memory?
l1 cache l2 cache
How fast is the l1 cache?
The L1 cache speed runs at the same speed as the CPU-central processing unit.
What was the first microprocessor to include both an L1 and L2 cache with CPU?
The Pentium Pro had both an L1 and an L2 cache on the CPU.
Is cache on a CPU?
CPUs do have a cache (either L1, L2 or L3), but cache is not exclusively on the CPU.
What is the type of cache built directly in the processor chip?
advanced transfer cache
Which cache level is on the motherboard and is separate from the processor chip?
L2 cache
What cache is generally incorperated into the CPU structure?
L1 Cache. And more recently, the L2 cache as well.
What cache typically has the most memory?
Caches are generally defined as L1, L2, and L3. If a CPU has any cache memory at all, it will have at least L1 cache. L1 cache is the fastest, and most expensive, type of cache memory. Usually CPUs will only have a very small amount of L1. L2 is typically larger, less expensive, and slower than L1. L3 is less expensive, larger, and slower than L1 or L2, if present. All three levels of cache memory are magnitudes faster than system memory. Systems withequivalenthardware, including CPUs will identical speeds, will perform better at certain tasks when more cache memory is present, with L1 cache adding the most performance boost.
What is the size of L1 and L2 cache?
Usually the size of the L2 cache will be larger than the L1 cache so that if data hit in L 1 cache occurs, it can look for it in L 2 cache.. If data is not in both of the caches, then it goes to the main memory...
What is the size of the data bus and the L1 cache on a Core 2 Duo CPU?
64 bit data bus and two L1 (64KB) caches; one L1 cache for each core (cpu)
What is the size of the data bus and l1 cache on a core 2 duo CPU?
64 bit data bus and two L1 (64KB) caches; one L1 cache for each core (cpu)
What is an l1?
L1 cache (i.e. Level 1 Cache)is the short memroy present with the CPU which stores the instructions or data in a queue for quick access for the CPU.
