Is it necessary to add a memory module on a laptop, and is it useful to add a memory module on a lap

It is necessary for laptops to increase memory.

1. Memory is an indispensable part of computers (PCs, microcontrollers). Unlike dispensable external memory, memory is a component that reads and writes on a bus; Memory is more than just a data warehouse. In addition to a small number of indispensable programs in the operating system to reside in memory, the programs we usually use, such as Windows, Linux and other system software, including typing software, game software, etc., although a large amount of data including programs are placed on external memory devices such as tapes, disks, optical discs, mobile disks, etc., but any data in external memory can only be really used when transferred into memory.

Any input (from external memory, keyboard, mouse, microphone, scanner, etc.) and any output (display, printing, audio, writing to external memory, etc.) on a computer can only be made through memory.

2. At present, mainstream notebooks are generally equipped with 4G memory as standard, and the needs of different system types for memory are also different, XP systems generally need 2G, Win7 or Win8 at least 4G, which is only used to meet the basic needs, if there are more programs running, or the programs running are relatively large, then the memory is a little stretched, and at this time it is necessary to add memory to meet the needs.

The average game 2G is very good. 4G is a bit of a waste. The main performance of the computer is determined by the motherboard and CPU, as well as the graphics card, not just because the memory is large.

DDR3 of course will be better,**Slightly more expensive,It is recommended that the landlord go to Jingdong** to inquire and order! That's where I bought it!

If you can add to 4G, I don't know if your motherboard can support 4G

DDR3 is more expensive, and it is possible that your board may not necessarily support DDR3, so it is recommended to buy the DDR2 generation for about 500 yuan.

In the case of graphics cards like 3430, there is no need to add more.

2G dual-channel is very good, and games that consume memory and require 4G, 3430 can't be played. DDR3 is of course better than DDR2, and the price is about twice as wrong.

Memory** fluctuates greatly, see the day for details**. DDR2 800 2G is about 150.

DDR3 is not easy to buy, of course more memory is beneficial.

Home use laptops.

After a year or two, the memory will be full, the operation will lag, and the response time will become longer, even if the system is cleaned or reinstalled.

The system will still be used for a period of time, then the laptop will add a memory module.

Did it work? 1. It is useful to add memory modules to notebooks.

2. The memory module is the bridge to communicate with the CPU. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer. Memory is also known as internal memory.

It is used to temporarily store computing data in the CPU, as well as external memory such as hard disks.

Data exchanged.

3. As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation, and when the operation is completed, the CPU will send the result out, and the operation of the memory also determines the stable operation of the computer.

4. Therefore, adding a piece of memory can improve the efficiency of system operation, increase the storage amount of memory, and enable multiple programs to exchange data with the CPU at the same time. However, it can also be seen from here that although only the size of the memory can improve a certain performance, the bandwidth and frequency of the memory are also very important, and the frequency determines the speed of processing, so the size should be larger, and the higher the frequency, the better.

That's all there is to you about whether it is useful to add memory modules to notebooks.
