[PConline sea election shopping guide] In recent years, the memory of mobile phones has increased dramatically, and the mainstream configuration in previous years has fallen behind. The memory we usually talk about is generally divided into two types, one is RAM, which is running memory, which is used to temporarily store data, and data will be lost after power off. The other is ROM, which is used to store data for a long period of time. Even if it is turned off, the data will not be lost. Today's top-end mobile phones can have up to 6GB of RAM, while large-capacity mobile phones can have up to 256GB of ROM. But these numbers are not worth showing off in front of the laptop. Generally we refer to the RAM of a computer as memory, and the computer ROM is commonly known as a hard disk. Laptop RAM can now reach 8GB or 16GB or even larger, and laptops with 8GB of memory are not necessarily high-end models. Over time, computers are also upgrading. Not only has the performance of computer processors increased dramatically, but the capacity of computer memory has also multiplied many times. Once upon a time, the computer's RAM reached 1GB, which is the mainstream. At that time, the computer application did not require much memory. Even if only 1GB of RAM was provided, the computer could run smoothly. Nowadays, the computer is generally equipped with 4GB of RAM, 8GB of RAM and even 16GB. RAM computers are also common, and RAM development is still relatively fast. The reason why such a large-capacity RAM is provided is mainly to ensure that the system can run smoothly in multi-task operation. 4GB RAM is not too large for a computer. To ensure that the system stays fluent during multitasking, at least 8GB of RAM is required. Laptops are different from desktop computers. Some laptops cannot upgrade memory. Therefore, to buy a laptop should be forward-looking, it is best to choose a larger memory laptop. Occasionally, the computer appears to have "lost response" or "page crash" under multi-tasking operation. This is often due to insufficient memory. When you encounter such a situation, it will inevitably make people feel upset. If the information is not saved in time, it is likely to cause loss to the user. The larger the RAM capacity, the less likely it is to happen. Next, Xiao Bian introduced four laptops equipped with 8GB RAM, they are Lenovo Y40-80AT-ISE, machinist Black Hawk F57-D2 light speed version, Apple 12-inch MacBook (MK4N2CH/A) and Shenzhou Ares Z7 -SL7S4.
