L1 = Level 1. This is a shorthand notation for a very fast, tightly-coupled cache.
Typically L1 caches are fairly small, but very fast - usually on the order of a couple of clock cycles latency (the time between when a processor make a read request to memory and the time the data is retrieved from memory).
L2 = Level 2. This is another type of cache which is usually somewhat larger (usually by a factor of 16 or so bigger than L1), and slower (read: less expensive). Even though it is slower than L1, it is still much faster than accessing main memory. Systems that have multiple processors may use L2 for sharing information among the processors. That is, each processor has its own L1 cache, but only one L2 which is shared among the processors. Latency here is on the order of 16-32 clock cycles.
Main memory (typically DDR2 or DDR3) can be 64-128+ clock cycles of latency. This means that if you have a very fast processor with no cache (or a cache that is too small) the processor will spend far more time (by a factor of 64 or more) just waiting for data to be retrieved from memory!
What is example single core processor?
An example of a single core Processor is anything from Intel's first processor to the late Pentium 4 era. There are also some single core Pentium Core 2/duo line products but those were very cheap for consumers.
What is the benchmark speed for Intel P4 3.6 GHz CPU?
There are lots of benchmarks. Without knowing what benchmark you wanted to test on the processor, it would be impossible to give you its score. Even then, the benchmark is only useful if you have the score from other processors to compare it to.
The unit that performs the arithmetic and logical operations within the processor?
The unit that performs the arithmetic and logical operations within the processor is called the Arithmetic Logic Unit (ALU).
Is it good or bad for a CPU to have multiple cores?
The more cores/processors the more independent parallel tasks a CPU/microprocessor has the potential to run at the same time (not serially timeshared on a single core/processor). This is usually considered good as it improves the effective processing speed of the CPU/microprocessor without having to run on a faster clock. However it can also be considered bad as it makes the CPU/microprocessor more complex and harder to build, usually making it more expensive. But ultimately it is a trade off and you must pay for what you get.
What are the functions of a CPU?
The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the functions of the computer or other processing device.
What is the purpose of the TLB located within the Pentium class -microprocessor?
The TLB, or Translation Lookaside Buffer, is a hardware cache within the processor's bus interface unit that stores recently used copies of Page Table entries. This speeds up conversion from virtual address to physical address.
They are basically formats for which CPU format will fit into what board. For example, any core 2 duo processor from Intel is probably an LGA 775 and will fit into LGA 775 socket motherboard. Any Core i7 processor will fit into any LGA 1366 socket motherboard. The list goes on.
What is the current processing speed of a decent computer (in GHz)?
Processor speed is not as important as it was.Anything above 1.5 Gig is plenty fast for most needs.RAM is more important.Get 1 Gig,more is usually a waste.Don't expect to suft the net on dialup.You need DSL.
The size of a Pentium III CPU L1 cache?
The L1 cache on a Pentium 3 (And most all processors) is divided into two caches, the data cache and the instruction cache. This may be because the instructions tend to have a high spacial locality while data has higher temporal locality. At any rate, all 4 variants of the Pentium III used 16Kb data cache and 16Kb instruction cache, which makes 32Kb total.
(The size of L2 cache varied based on the core.)
What are the steps involved in initializing an 8259A micro processor chip?
1. find out the system base address from memory map of system. for 8259a it is FF00H.
2. find the internal address for the device. in 8259A there are 2 internal pin A0 and A1.
3.add the internal address to the bus address to get the system address for each internal address.
What are the functions of the CU?
The function of the Control Unit is to Fetch, Decode, Execute and to Store information.
How do you transfer old CPU files to new CPU?
You don't. The CPU is your processor.
You can transfer files to a new HDD, one of the easiest ways is to slave up your old drive and copy everything over.
What are the disadvantages of a CPU?
If you don't have one in a computer, it won't do anything.It wont work at all cause CPU is memory in a computer
The only bad thing about it is that you have to have a GPU that is equally powerful , and not to mention that they can get pretty hot so it's a good idea to buy a better fan
List the unconditional branch instruction in 8086 with examples?

What type of computer applications would be enhanced by a dual-core processor?
Not many.
Without being specifically written to take advantage of multiple processors or else recompiled with altered settings, to do so, software gains no advantage from multiple processors (or 'cores').
However, you still have the advantage of 'extra processor power' in general (e.g. two processors of the same type is still twice the processing power of a single processor of that type).
The move to multiple cores and multiple processors has more to do with physical limitations which prevent manufacturers from simply increasing the 'clock' as had been the case for about a decade previously.
Are processor is the brain of computer?
yes the processor does all the calculations and the RAM helps to push it through
