Memory is where programs and data are stored, for example, when we use WPS to process a document, when you type a character on the keyboard, it is stored in memory, and when you choose to save, the data in memory will be stored in a hard (magnetic) disk. Before we can understand it further, we should also recognize its physical concepts.
Memory generally uses semiconductor memory cells, including random access memory (RAM), read-only memory (ROM), and cache. Simply because RAM is the most important memory of them all. S (Synchronous) DRAM Synchronous Dynamic Random Access Memory:
The SDRAM is 168 pins, which is the memory currently used by Pentium models and above. SDRAM locks the CPU and RAM together through the same clock, enabling the CPU and RAM to share a clock cycle, work synchronously at the same speed, and the rising edge of each clock pulse starts to pass data at a speed that is 50% faster than EDO memory. ddr(double data rage)ram :
An update to SDRAM, it allows data to be transmitted on the rising and falling edges of the clock pulse, so that the speed of the SDRAM can be doubled without increasing the frequency of the clock.

Storage: 1024 bytes*1024KB*1024MB
2 bytes = one Chinese character.

Memory is not for storing things. What you call storage is a hard drive, and memory is just exchanging temporary data.
-
This is the space where data is exchanged ... For example, if you want to copy a file from disk D to disk E, the file size is 500m, the computer will first copy the file of disk D to the memory area, the memory is just loaded and copied to disk E, if the memory is only 512M, then the system can only be divided into several sections, copied to disk E, in combination.

Summary. 16G RAM is the size of this bridge. The larger the processing speed, the faster the processing speed, what does the computer memory 16G have to do with memory, and how can 16G memory have 1TB of memory.
What about computer memory 1, it is generally said that it is easy to take the year, and the memory module can be said to be equivalent to its role as a bridge. 2. It is mainly responsible for the hard disk and the motherboard, which is equivalent to the exchange of data on the hardware and the processor. 3. Memory not only plays the role of a data warehouse, but also uses the program to eliminate the sequence, such as games and typing software, which can only be used if the memory is added.
16G RAM is the size of this bridge. The larger the processing speed, the faster the processing speed, how can there be 1TB memory?
You said 1t. It should be the capacity of the computer's hard drive. It is the place to access files. There is no commonality between the two.
1t should be the storage capacity of the hard disk. Some would say it's memory capacity.
Kiss. The largest memory module at the moment is 16G. There is no 1T of memory.
Is it necessary to match the computer with another hard board?

When buying a laptop, everyone will pay special attention to several issues, such as how many generations of CPU, whether there is a single monitor, and how much memory there is. Because everything involved in these issues can have a direct impact on the performance of the notebook. Both the CPU and graphics card are well chosen.
Newer models are generally available. But memories are not the same. Whether it's ** or the old model, there are many choices.
How to choose between 2G and 128G is a difficult problem. Now 1GB of memory is not enough, 2GB is difficult.
First, let's come up with a concept. The memory of the laptop is not the same as the memory of the mobile phone. This is not a storage space.
In contrast, the memory of a laptop is the RAM of the phone, and the hard drive is a ROM. When the computer is running, the CPU will transfer the data to memory for processing, and then bring it back up after processing. Memory is the decisive condition for the stable operation of a computer.
This has led many friends to fall into the misconception that the larger the memory choice, the better. There is a classical theory in economics called the marginal diminishing effect. It means that if an input factor increases in equal quantities in succession all else being equal, the increment of the product provided decreases after it reaches a certain value of output.
A vivid metaphor is that when you're hungry, eating one bun will be satisfying, and eating a second bun will be refreshing, but when you eat more and more, you don't want to eat it. If you continue to let you eat at this time, you will be disgusted. The same goes for memory.
So, only by choosing the right memory, the computer can be smooth and the money can be well spent. So how many grams do you choose? Don't worry, let's divide the computer into study and leisure, daily office, gaming, and design according to the purpose of the computer.
Study and leisure, daily office.
Computers for this purpose generally open ** device, office, browser, PS and other software. As long as these software are not used in large quantities, the data required to run is not large, and it is enough to choose 4G memory.
Game. It is a computer used for gaming. It doesn't mean that it has to be large, but it still has to be chosen according to the requirements of the game being played. You can search the web for the game's spec requirements and choose a higher spec to play smoothly.
Devise. Computers designed for use will have higher memory requirements. In the past, when I was learning PS in Xiao Cafe, the computer's 4G memory began to get stuck in a few materials, and the antivirus software has always been a red alert.
And when you're designing, you're basically going to open multiple browsers at the same time to find materials. So the memory must be large enough, 8G is barely enough. It is recommended to start with 16G dual channel.
In this way, you won't be particularly irritated when you use it, and you can continue to be patient and teasing it.

For now, two 512 is better than one 1G because it supports dual channels. >>>More
It would be better to change it directly to a 2g one
If conditions permit, it is recommended that the landlord use the same model of memory as the first one, (at least the same specification of the memory module) to avoid some compatibility problems.
RAM random access device, do the main memory, ROM read-only memory, now generally not used, EPROM, rewritable memory, generally erased with ultraviolet light, can be written electrically, used less. E2PROM, electrical erase, electrical write, is now widely used, such as the BIOS of a computer, etc.
1. Core memory:
It is the main form of random access computer memory. This type of memory is often referred to as core memory, or informally as core memory. >>>More
