How much cache memory is available in Intel i3 Processor?
3 mb
Why was the first Intel Celeron processor not as popular as expected?
The original Intel Celeron processor was not as popular as expected because it lacked the level 2 cache to help reduce the price of the processor. With no level 2 cache, the processor acted much slower than the competitor processors.
What is an example of L2 cache memory size?
Level 2 (L2) cache is built onto the processor. On Older slot-mounted processors, L2 cache was external to the processor die, and ran at slower speeds than the processor. on socketed processors, L2 cache is built onto the processor. If the processor does not find the desired memory locations in L1 cache, it checks L2 cache next. However Processors with larger L2 caches perform most tasks much more quickly than processors that have smaller L2 caches for two reasons. Cache memory is faster than main memory and the processor checks cache memory for needed information before checking main memory.

How does a memory cache speed up computer processing?
Getting data from memory, or the hard drive is slow. If you store a part of the memory you think you will need soon, or often in cache, it will speed up processing by reducing wait time. Cache is much smaller, but much faster than memory and sits on the processor die.
What is processor cache memory?
Processor cache is intermediate memory between the processor itself and main memory (RAM). Because processors can read data so much faster than main memory, the speed of a processor would essentially be limited to the speed of RAM if we couldn't find a way to increase the efficiency of accessing data in main memory. Caches, which have a much lower access time than RAM, help to mitigate this problem. Caches work on the principle of spacial locality. That is to say, they use the idea that if you access a location in main memory, then it is highly likely that the next memory location you want to access is very close to where you are. When you access main memory, the cache will actually pull in a "chunk" of data (often called a "cache line") in the hope that the next time you try to access data it will already be in the cache. Typically there are two levels of cache (though with the increasing popularity of multi-core processors, three levels of cache are becoming more and more necessary). The first level of cache (L1 cache) is what is directly accessed by the processor and is therefore the fastest (and most expensive) cache. L1 cache is usually split into two parts: data cache and instruction cache. The instruction cache holds the instructions of running programs that the processor needs to execute. The data cache holds the data being used by current instructions. The second level of cache (L2 cache) is where the L1 cache pulls in information from. L2 cache is slower than L1 cache, but is more affordable and can be much larger than L1. With the exception of L3 caches mentioned above, this is the cache which pulls information in from main memory.
How much is an iMac with g5 and Intel processor?
The G5 does not have an Intel processor it has an IBM Power PC processor.
What are the Uses of Cache a very high speed memory?
Cache is a high-speed memory device that is placed between a microprocessor and a system memory. A Microprocessor usually can process data at a much faster rate than what the system memory can provide. If this disparity isn't handled, we will end up with a microprocessor that's idling most of the time, because it has to wait on main system memory to provide the (or cosnume) data. With a cache, which could operate at a speed near the processor to shuttle data back and forth between processor and memory. Cache memory relies on a concept in computer science called locality of reference. This concept stipulates that when the processor accesses a piece of data, it is highly likely that it will access data that are also in the same locale in memory. A cache subsystem will fetch the requested data and those around to anticpate the next processor request.
What type of memory stores frequently used instructions or data needed by the CPU?
the memory that directly communicates with the CPU is called Cache Memory this is; When the processor(CPU) needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, the processor immediately reads from or writes to the cache, which is much faster than reading from or writing to main memory. A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.

What is the Significance of cache miss?
When you have a cache miss, this means that the cache did not contain the information needed by the processor. This means that the information will need to be fetched from memory. Retrieving data from memory is much more costly than from cache, therefore you will incur a "miss penalty" where the CPU will potentially have wasted cycles if there isn't other data it can process while it waits for memory. If the data is not in main memory, then a page fault (YAY My username!) occurs. This is very expensive and means that a lot of processor cycles will be wasted while a page is retrieved from the hard drive.
What is cache memory?
A small amount (normally less than 1MB) of high-speed memory residing on or close to the CPU. Cache memory supplies the processor with the most frequently requested data and instructions. Level 1 cache (primary cache) is the cache closest to the processor. Level 2 cache (secondary cache) is the cache second closest to the processor and is usually on the motherboard.AnswerA cache, in computer terms, is a place to store information that's faster than the place where the information is usually stored. Cache memory is fast memory that is used to hold the most recently accessed data in slower main memory. The idea is that frequently accessed data will stay in cache, which allows the CPU to access it more quickly, which means it doesn't have to wait for the data to arrive.In reference to your processor, the Cache Memory is the Processor's internal quick-hand storage that it uses for things that it's currently processing at that given time.As with most things, the more cache memory a processor has, it will usually run smoother and faster than one with less of about the same operating frequency.AnswerCache memory is usually "On Die" which means it is in the processor chip, which allows it to 'talk' with the processor direct at a much higher speed than standard RAM.cache is a small chip, that's usually placed inside the CPU or sometimes its right next to it and is responsible for providing direct access to the commonly used programs, rather than going back to the hard disk and ram again and again so cache makes it more fast than RAM, you know!!!AnswerPronounced cash, a special high-speed storagemechanism. It can be either a reserved section ofmain memory or an independent high-speed storage device. Two types of caching are commonly used inpersonal computers: memory caching and disk caching.A memory cache, sometimes called a cache store orRAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because mostprograms access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.Some memory caches are built into the architectureof microprocessors. The Intel 80486 microprocessor, for example, contains an 8K memory cache, and the Pentium has a 16K cache. Such internal caches are often called Level 1 (L1) caches. Most modern PCs also come with external cache memory, called Level 2 (L2) caches. These caches sit between the CPU and the DRAM. Like L1 caches, L2 caches are composed of SRAM but they are much larger.--------------------------------------------------------------------------------------------------------------------------------ANSWERI would like to point out the disadvantage of the Cache...Just in case the Cache memory is full and data that is required to process or an application required to run doesn't fit into the Principle of Locality (that is not in the near by location) then it is obvious that the time required for the main memory to access the information would increase...coz first the the data need to be relocated into the cache and then process over here if the cache memory was missing it would be quicker...furthermore being such an extensive memories they are very small in Memory Size which requires location and relocation of the data or applications.It allows commonly accessed data to be stored in full and referenced faster than recompiling the data each time.
