Computer architecture determines the performance of a computer and the nature of information that can be handled or processed by that particular computer. Small devices and embedded computer systems have very tiny physical specifications and they are known to perform at a level that is not too much energy conscious. These systems are also famous for their low-power requirements and whenever it comes to processing information, they will be able to do so for longer periods of time without running out of power. The computer architectures that are in existence take care of the information that is within the network and on the system according to what the computer has been equipped with.
Larger and more complex computer architectures are known to work wonders for the information that they have to deal with and process as the distributed and parallel nature of this architecture enables the systems to process all this information in real time and provide responses to the customers instantly. Simple computer architecture is only capable of simple computations and does not scale up to handle advanced calculations or processing requirements for the user. It is also portable and has a lower throughput than its complex architecture counterparts.
A computer architecture that is specialized in one of the parts of the overall structure tends to handle one aspect of the computation very well while leaving the rest not as well attended. For instance, if it is a graphics system that has been adapted to take care of generating prime numbers to keep an information system secure, the computer architecture will lean towards performing some of the calculations and not as well specialized in carrying out the rest of the computational task that would be expected from such an information system. This means that for any computational task or scenario, there is equivalent computer architecture for it.
There is also the difference between CPUs and GPUs where the GPU is a graphical processing unit and has been designed specially to take care of processing graphical information and visual coordinates for various systems while the CPUs are for ordinary computations. The difference between the two architectures is in the throughput and the number of instructions that can be carried out per second which means that a computer that has a CPU and a GPU will have both kinds of architectures. As such, it will be able to handle computational requirements comfortably without any strain on it.
32bit and 64bit architectures are also application areas of the different computer architectures and these determine the capabilities that the device will have. It also dictates what the computer will be capable of and how well it can carry out certain kinds of computations. This is the difference between the low level processing architecture and advanced processing architecture which is mainly used for modern computer systems that have been specialized for the growing information needs of businesses and scientific organization. The variations in the computer architectures also makes it possible to find out which one is best for your particular problem.
