If we are ready to assemble the computer DIY, then we first need to determine their own needs, confirm the use of computers, and then according to their own budget to determine the price of the machine. In addition to determining the price and performance of the machine, one thing we need to determine is the size of the machine. The choice of host size is mainly based on two reasons, one is to place the host space, the other is a personal preference. Some people like behemoths, some like small a
Many people should know about the short board theory, the main idea is that a cask can be filled with a minimum of a plank to decide, even if there are a lot of tall wood still cannot hold more water, short board theory in many respects are reflected, such as the dam cordon also has the shortest section of the dike decision, such as the domestic minimum consumption level, also has the lowest income of that
