Is it the system cache that uses more memory to run the program?

First, with regard to your second question, I would like to do the following:

You want to know the meaning of the system cache here is not too deep, you can search for it, look at a more detailed introduction, my understanding is to share the work of memory, for your question "system cache" I think you want to ask is "virtual memory", virtual memory is to share the working pressure of memory from the settings in the hard disk, generally used to store some page files, cache files and the like, then generally set to 2 3 times of the physical memory, and set it in the disk where the non-system files are located, That is, do not set it in the C: disk, the general public is set in the D: disk.

I don't know if mine is what you want, if there is anything you don't understand, send me a message).

Here's an introduction to the servers.

With the development of servers today, servers that adapt to various functions and environments continue to appear, and there are various classification standards.

1.According to the application level, it is divided into four categories: entry-level server, workgroup-level server, departmental server, and enterprise-level server.

1) Entry-level servers.

2) Workgroup-level servers.

3) Departmental servers.

4) Enterprise-grade servers.

2.According to the processor architecture of the server (that is, the instruction system used by the server CPU), the server is divided into three types: CISC architecture server, RISC architecture server and VLIW architecture server.

1) CISC architecture server.

2) RISC architecture server.

3) VLIW architecture server.

3.According to the purpose of the server, it is divided into two categories: general-purpose servers and dedicated servers.

1) General-purpose servers.

2) Dedicated servers.

4.According to the chassis structure of the server, the server can be divided into four categories: "desktop server", "rack server", "cabinet server" and "blade server".

1) Desktop servers.

2) Rack servers.

3) Rack servers.

4) Blade servers.

5. According to the purpose, there are web servers, e-mail servers, database servers, DNS servers and so on.

The server machine is the same as the computer we use, as long as it is configured, it can be used as a server. The host of the Internet café is also called the server machine, but the host of the Internet café does not need to be configured too high, and the server side of the online game is a real server machine, and the configuration is quite high, mainly depending on the memory and CPUThe system cache is c:

The remaining space on the disk is used as virtual memory

Of course, the home computer is the first choice to run the program, the system cache is the thing that the file that exists in the temporary folder of the system, the home computer wants to update the system cache as long as it is refreshed, if it is a server, it should be set to update the system cache as the first choice, for example, a new change of a ** has been opened web page, if the server does not update the cache, then when other computers access the page, it is still the web page before the change, Therefore, the server needs to make updating the system cache preferred.

Both should not be configured only by Hu Heng, depending on the needs, and it is not easy to say which one is better.

1. The system cache can only function on the read and write of the hard disk. If it's an SSD, you can set the system cache to a little smaller.

2. It depends on the total size of the physical memory: program memory, if the memory is not enough, the memory cannot be run. The system cache is running a little slower at most, so, on a computer with a small memory, it must be the program memory first, and on a computer with a large memory, such as 16g memory, what program can run, so you can allocate more to the system cache.

Look at what you're using, if the software program you run is more trustworthy and large, it must be using more memory to run the program number.

You should be able to optimize the system, then it is recommended that you open the cache.

Choose the system cache, you can improve the system performance, but because the system file will be pre-read into the internal answer field storage, so the system occupies a higher memory in memory, and the space of the corresponding application slips less, it is not recommended to open this on the computer with small memory, but you should have enough to use the computer to open the system cache, because when the system occupies a high space, the processing of virtual memory is also faster, and the application also has enough memory to run.

Generally speaking, the capacity of the same ** memory is inversely proportional to the speed. The more you load, the slower it is.

Cache refers to the intermediary between low-speed and high-speed devices.

For example, compared with the CPU speed, the memory speed is very slow, add a faster L1 cache, L2 cache cache, query in the cache first, if you can't find it, then go to the slow memory query, put the search result in the cache, and the next time you use it, it will be fast.

Compared with memory, the hard disk or network transmission is much slower, so for the sake of speed, you can put a part of the data in the memory, check it in the memory first, and if the memory can't be found, go to the hard disk or the network, and put the search result in the memory, which is the cache.

Therefore, the program is running in memory, and the cache is just an intermediary role, which may be the memory as a cache, or it may be another device.

Neither, run in the combinator.

Memory here refers to memory space.

Memory is the memory component of a computer, which is used to store the raw data of the computer's operation, intermediate results, and programs that instruct the computer to work.

Memory can be divided into random access memory and read-only memory, the former allows data to be read and written, the program in the disk must be called into the memory before it can run, ** the processor can directly access the memory, and exchange data with the memory. When the computer is powered off, the information in the random access memory is lost. The latter's information can only be read out, not written at will, and will not be lost even if the power is off.

Generally, the memory used in computers is inserted into the motherboard in the form of plugs, which is called a single in-line memory module, commonly known as a memory module. There are 30-line, 72-line, 168-line and other types of memory modules. How many wires refers to the number of pins when the memory module is plugged into the motherboard, so the number of pins in the slot of the memory module on the motherboard determines how many lines of memory you can only plug in.

Due to the complexity of the circuit, binary numbers are used in the computer, only 0 and 1 two numbers, every two into one, the easiest to express with a circuit, such as 0 represents the circuit is not through, 1 represents the circuit is smooth. When we usually use a computer, we don't feel that it is using binary calculations, because the computer will automatically convert the information we input into binary, and then convert the calculated binary numbers into information that we can see and display it on the screen. The memory contains a large number of basic units, each memory cell can hold eight binary bits (i.e., an integer between zero and two hundred and fifty-five, a letter or a punctuation mark, etc., called a byte (i.e., 1 = 8 The capacity of the memory is based on bytes, and each cell has a unique serial number, called an address.

The processor accurately manipulates each cell and processes the data by virtue of the address. Since the byte is so small, we define several larger units, which are carried to the tenth power of 2, and the units are kb, mb, gb, tb, etc.

Common memories include synchronous DRM, double-rate synchronous RAM, and interface DRM.

I hope I can help you with your doubts.

It must be related! Your processor and memory are good, it should work well!

Just see how a 2G can tell if it is DDR.

Memory is one of the most important components of a computer, and it is the bridge that communicates 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, also known as internal memory, is used to temporarily store computing data in the CPU, as well as to exchange data with external processors such as hard disks. 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 computing cover judgment machine.

Memory is composed of memory chips, circuit boards, cheat manuscripts, and other parts.

Read the program into the memory first, and then the memory and the CPU do data exchange calculations, so that the speed will be much faster, and there is no need to read the hard disk frequently, and the speed of the hard disk is slower than the memory cracking.

Hard disk storage is slow and can't keep up with the CPU, so you have to use memory.
