CISC:

The acronym is variously used.

If it reads as above (i.e. as CISC computer), it means a computer that has a Complex Instruction Set Chip as its cpu.

It is also referred to as CISC computing.

It is sometimes called a CISC “chip”. This could have a tautology in the last two words, but it can be overcome by thinking of it as a Complex Instruction Set Computer chip.

  1. CISC chips have an increasing number of components and an ever increasing instruction set and so are always slower and less powerful at executing “common” instructions.

  2. CISC chips execute an instruction in two to ten machine cycles.

  3. CISC chips do all of the processing themselves.

  4. CISC chips are more common in computers that have a wider range of instructions to execute

RISC:

The acronym is variously used.

If it reads as above (i.e. as RISC computer), it means a computer that has a Reduced Instruction Set Chip as its cpu.

It is also referred to as RISC computing.

It is sometimes called a RISC “chip”. This could have a tautology in the last two words, but it can be overcome by thinking of it as Reduced Instruction Set Computer chip.

  1. RISC chips have fewer components and a smaller instruction set, allowing faster accessing of “common” instructions

  2. RISC chips execute an instruction in one machine cycle.

  3. RISC chips distribute some of their processing to other chips

  4. RISC chips are finding their way into components that need faster processing of a limited number of instructions, such as printers and games machines

Intel Core i3, Core i5, and may be Core i7 CPU have been there from last 1-2 years but I don't know the real difference between these. Can someone help me with the difference between these three so that I can decide which one to buy.

Lets say I have windows 7.

This OS I can install on Core 2 duo, dual core, core i3 and so on.... even though number of cores and threads are different for different processor. Then How OS Schedules the process for it?

Even different processor have different architecture for reading and executing instruction, how OS takes care of it? I mean how OS prepares the instruction for it?
