The Leap of Speed&Capacity

In last class, I knew the production of computer. The speed and the capacity are increasing very fast in recent decades. I can see changes when I changed my computer every two or three years. CPU keeps significant status inside a computer, which also helps to increase the speed.

CPU currently is running very fast. It operates the whole system very frequency and it has been close to four GHz. The core has reached two to four, which looks like a good management office of a computer. But if a computer has good factory, it should have a strong warehouse to support the factory, the warehouse is called hardware. However, long ago, the speed of hardware is very bad. People can assume that the CPU handle 2 0 GB per second and the number of capacity of hard disk can store per second, but the warehouse of hard disk could only provide 120MB. It means that the power of calculating has been greatly wasted, which predicates that CPU is often in unnecessary waiting state. With the time flies, someone comes up with a good way. Because the warehouse is so large, so they do not increase the speed, and then they can build a smaller-capacity transition. The transfer station is located between the factories and warehouses. Preparation of summary of the transfer is faster than a more hard disk can be ahead of CPU resources that required temporary deposit, which can effectively enhance the system processing speed. This is the most basic idea of the generation of memory. Because the contradiction between CPU and the two hard devices drive are different in huge performance that they can’t be reconciled, so it just simply set up a transfer station to meet the requirement of CPU.

The benefits of experiencing into memory and the memory particles are all designed on the motherboard by many of the system developers immediately. However, it still brings the problems, for example, the capacity can’t be expended. In order to solve these problems, technical experts eventually made the memory parts independent, and they were designed to be splat, through a slot for the motherboard, and finally the memory was also born. The increasing of speed and capacity are achieved.
