Does a polygon have more sides or more angles and why?
yes a polygon does have the most number and sides because they have the most number of shapes with the most number of sides

Diff bw risc and cisc?
CISC stands for Complex Instruction Set Computer. CISC chips are relatively slow per instruction,but use little instructions RISC stands for Reduced Instruction Set Computer. A fewer, simpler and faster instructions would be better, than the large, complex and slower CISC instructions. However, more instructions are needed to accomplish a task. It's easier to write powerful optimised compilers, since fewer instructions exist.
What is the main difference between RISC and CISC in computer architecture?
Reduced Instruction Set Computer (RISC) vs. Complex Instruction Set Computer (CISC). (1) CISC computers typically require more than one clock cycle to execute a given instruction (2) RISC computers typically require only one clock cycle to execute a given instruction That said, a CISC "opcode" can often perform more than a RISC "opcode". This results in much shorter code for CISC machines which is much easier to read and maintain. That said, CISC computers often have "dead cycles" in which the processor isn't doing anything useful, or is performing a redundant command. As an example, if one tries to do a MULT memoryLoc1, memoryLoc2, register followed by an ADD memoryLoc1, memoryLoc2, anotherRegister, then a CISC machine must access main memory (or cache) 4 times and perform 2 computations and two moves from the ALU to a register. A RISC machine (while requiring more, but simpler, instructions) would never need to go out to memory for the additional 2 times since the information was already retrieved. Memory access can be a very time expensive operation. All in all, RISC code is much more optimize-able and significant performance improvements can be realized over CISC.
What are the advantages of risc and cisc?
Reduced Instruction Set Computing (RISC) is a CPU design concept that seeks gains in power as a trade-off for simplified instructions. This design philosophy is directly opposed to Complex Instruction Set Computing (CISC), which is the basis of the x86 style processors of the vast majority of home PCs and laptops.Performance-OrientedThe construction of the RISC processor is such that performance is the priority, rather than raw power. When RISC and CISC were developed, the bottleneck of microprocessors was power, meaning that CISC won out and efficient, performance-oriented chips were used less and less. RISC came back into vogue when the need increased for chips that make efficient use of portable battery power.Less VersatileSince the instruction set is so simple, that is, one instruction per cycle, RISC processors tend to be better used for simple and repetitive logic operations. CISC processors are truly "general purpose," meaning that they can pipeline multiple instructions at once without a preference for simpler or more complex applications. RISC processors need to be programmed in a very particular fashion.SimplerThe performance orientation of the RISC architecture is due to its simple and efficient instruction set. This simplicity means that RISC processors are easier to design and inexpensive to produce, making them ideal for purpose-built and cheap computing machines that execute repetitive instructions.Long Instruction StringsRISC processors can be adapted to run CISC style instruction strings, but they are incredibly inefficient at doing so. Since a RISC processor can only handle one instruction string at a time, code needs to be more compartmentalised and, therefore, more complicated.
What is the difference between CISC and RISC processor architectures?
CISC, or Complex Instruction Set Computing, provides a rich instruction set that has instructions for many different types of operations, e.g. logic, math, floating point math, and so forth. RISC, or Reduces Instruction Set Computing, has a much sparser set of instructions that allow you to do very much less with each instruction. Because the individual instructions are simpler, a RISC chip can execute many more instructions than a CISC chip in a certain amount of time. Additionally, because it needs many fewer transistors, a RISC chip can be built to use much less power than a CISC chip, even with power saving techniques like temporarily turning off unused parts of the chip. In modern computing, examples of CISC chips are the Intel Core and Atom series. Example RISC chips are the ARM and PowerPC chips.
Why arm7 processor is not a perfect risc processor?
There is still considerable controversy among experts about which architecture is better. Some say that RISC is cheaper and faster and therefor the architecture of the future.Others note that by making the hardware simpler, RISC puts a greater burden on the software. Software needs to become more complex. Software developers need to write more lines for the same tasks.Therefore they argue that RISC is not the architecture of the future, since conventional CISC chips are becoming faster and cheaper anyway.RISC has now existed more than 10 years and hasn't been able to kick CISC out of the market. If we forget about the embedded market and mainly look at the market for PC's, workstations and servers I guess a least 75% of the processors are based on the CISC architecture. Most of them the x86 standard (Intel, AMD, etc.), but even in the mainframe territory CISC is dominant via the IBM/390 chip. Looks like CISC is here to stay …Is RISC than really not better? The answer isn't quite that simple. RISC and CISC architectures are becoming more and more alike. Many of today's RISC chips support just as many instructions as yesterday's CISC chips. The PowerPC 601, for example, supports more instructions than the Pentium. Yet the 601 is considered a RISC chip, while the Pentium is definitely CISC. Further more today's CISC chips use many techniques formerly associated with RISC chips.So simply said: RISC and CISC are growing to each other.
What do RISC and CISC stand for and what are the differences in practice?
RISC stands for Reduced Instruction Set Computer CISC stands for Complex Instruction Set Computer RISC processors have a simpler set of machine instructions than CISC processors, but are intended to be more efficient and flexible in processing programs and data. Because of the reduced instruction set, RISC processors demand more effort on the part of the compiler (not the end user) and use longer machine language programs. RISC processors are more flexible in the sense that they are not as preconfigured in how they process programs and data. CISC microprocessors actually preceded RISC microprocessors and were derived from microcontroller based mini-computers such as the HP2100. See the Wikipedia entries on "Complex Instruction Set Computer" and "Reduced Instruction Set Computer" for more.
What is a CISC processor?
"CISC" stands for Complex Instruction Set Computer, CISC processor can execute complex instructions in one or more clock cycles. It is meant to differentiate it from a RISC or Reduced Instruction Set Computer, which can only perform one simple instruction in (usually) one clock cycle. A CISC is meant to have many machine level commands carried out as part of a single assembly command. The assembly command is broken into a series of "micro-code" commands which are executed internal to the processor by a "micro-code sequencer".
What is the difference between CISC and RISC?
RISC : Reduced Instruction Set Computer. A RISC system has a reduced number of instructions (making it easier to implement efficient optimizing compilers) and more importantly it is load store architecture where pipelining can be implemented easily. e.g. IBM PowerPC, ARM, Intel i960CISC : Complex Instruction Set Computer. A CISC system has complex instructions (making it easier for a human to directly program in assembly language) such as direct addition between data in two memory locations. e.g. Intel Pentium (x86), DEC MicroVAX, Motorola 680x0
