Memory What do we usually mean by memory?

Memory refers to the capacity of the microcomputer, the microcomputer with large memory has a large capacity, and the mobile memory generally refers to the U disk and mobile hard disk, etc.

The running memory is 12 GB and the storage memory is 512 GB.

Running memory, also known as main memory, refers to the memory required by the program to run, which can only temporarily store data for exchanging cache data with the CPU, generally referring to random access memory (RAM).

The size of the running memory directly determines how many programs the system can run, and the larger the running memory, the faster the system can run the program. The development of memory is closely related to the degree of processor process and system optimization.

If the processor itself can't keep up, or if the system is not optimized well, even a larger memory is a waste of resources.

A memory that allows a cell anywhere in the array to quickly write and read data out in a random order. It is where the computer holds the operating system, applications, and user data, and unlike a hard disk or other storage device, it allows the processor to get the data more quickly, but all the data stored in the RAM is lost when the computer is shut down.

When the user turns it on again, the computer will automatically reload the operating system and other files (usually from the hard disk) into a human-like short-term memory, which resembles a person's long-term memory. Short-term memory is aimed at the current work and can store many data at the same time. Long-term memory can be short-term memory and needs to be refreshed.

Memory is one of the important components of a computer, also known as internal memory and main memory, which is used to temporarily store computing data in the CPU and exchange data with external memory such as hard disks.

It is the bridge between the external memory and the CPU, and all the programs in the computer are running in memory, and the strength of memory performance affects the overall performance of the computer.

As soon as the computer is running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation, and when the calculation is completed, the CPU will send the result.

Of course, running memory and fuselage memory are different, because running memory is a thing that we usually understand to affect the response speed of mobile phone applications, generally 4G to 16G. And the fuselage memory is the storage in the mobile phone,The software system and the **** that is usually included in such a fixed space,Now it is generally 64G starts。 <>

Running memory is what we usually understand, 8G memory, 6G memory, 12G memory of mobile phones, such a concept, and what does it do? It's like a very responsive treatment plant. You can put each software on it to run, and then you will get a quick response, the larger the space, the more software can be accommodated to run and use the software at the same time, and the sneak running in the background will not affect the overall speed.

The body memory is what we usually understand as the storage space of the mobile phone, because now the storage space of the mobile phone and the mobile phone are one, and the original memory card was used in the earliest days, and that thing was used to store things. It itself does not contain a system of mobile phones.,It's to store ****** such things.,The larger the space, the more files the phone can store.,It doesn't have much to do with the speed of the phone.,Because that's affected by the running memory.。 The size of the body's internal memory only affects the maximum number of files that can be stored on the phone.

Now the ** of mobile phones is getting cheaper and cheaper, and it is clear that there is also the earliest time in Phuket, 4 points and 64 periods, this mobile phone, running memory and body memory, even if it is very good, because 4 years ago, this kind of mobile phone cost 2000 yuan, and now 2000 yuan 12g-256g memory can be selected. Because the technology is gradually advancing, the cost in this area is also gradually controlled, and the cost is low, so that you can provide you with a better configuration of the mobile phone.

are two concepts. Running memory is when you use the phone, if the memory is large it will not lag. But the fuselage storage memory is that if you ** a lot of things will be stuck, if not** it will not be stuck.

These two concepts; The content of the mobile phone in the process of operation depends on how many apps are opened and how much content is occupied, and the memory of the fuselage can store some files**or some**.

are two concepts. First of all, the first one affects the speed of our mobile phone. Even if you delete too much garbage, it's useless. It's internal, but the second one is faster and the memory is larger as long as you delete the app.

There are two types of computer memory: ROM (read-only memory) and RAM (random memory).

ROM is generally used to store the basic programs and data of the computer, such as BIOSROM, RAM means that it can both read data and write data, when the machine power is turned off, the data stored in it will be lost, memory is one of the important parts of the computer, it is a bridge between external memory or land and CPU, and all programs in the computer are run in memory.

The performance of memory has a great impact on the computer, memory is also known as internal memory and main memory, its role is to temporarily store the operation data in the CPU, as well as the data exchanged with external memory such as hard disks, as long as the computer is running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation, and when the operation is completed, the CPU will send the results out.

Features of computer memory:

Computer memory, is a device or system used to store information for immediate use by a computer or related computer hardware and digital electronic devices, the term memory is often synonymous with the term main memory or main memory, and the ancient synonym for memory is store.

Computer memory runs at a high speed of excitation compared to slower but higher capacity storage, and if needed, the contents of the computer's memory can be transferred to storage, and a common way to do this is through a memory management technique called virtual memory.

Modern memory is implemented as semiconductor memory, which stores data within the memory unit from the built-in MOS transistor and other components on the integrated circuit, there are two main types of semiconductor memory, easy to lose and non-volatile.

Examples of non-volatile memory are flash ROM, PROM, EPROM, and EEPROM memory, and examples of volatile memory are dynamic random access memory (DRAM) for primary storage and static random access memory (SRAM) for CPU cache.

When people usually refer to the memory of a computer, they usually mean the internal memory.

It is a critical parameter of a memory module. It is used to temporarily store computing data in the CPU and to exchange data with external memory such as hard disks. The computer is a modern electronic computer used for high-speed calculation, which can perform numerical calculations and logical calculations, and also has the function of storage and memory.

It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.

The running of all programs in the computer is carried out in memory, and the operation of memory determines the stable operation of the computer, so the performance of memory has a great impact on the computer. As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory for calculation, and when the calculation is completed, the CPU will send the result.

About memory

Memory is one of the important components of a computer, which is composed of memory chips, circuit boards, gold fingers and other parts, and it is a bridge to communicate with the CPU.

Internal memory includes registers, caches, and main memory. The memory is inside the CPU chip, the cache memory is also made in the CPU chip, and the main memory is composed of several memory modules inserted into the memory slots of the motherboard. The size of the memory and capacity will affect the running speed of the computer.

If you want to copy the Internet will be very detailed, but I guess you don't have so much time to look at it carefully, I will say according to the market, the role of the first memory is to temporarily store the data of the system running program, for example, we open the system, the data required for the system to run is loaded into the memory, or I open a QQ, then the data of the QQ program is also running in the memory, then you may think that it is not stored in the hard disk? It can be said that the things that do not run are stored in the hard disk, and the running ones are stored in the memory, so sometimes there will be technicians who say that you don't have enough memory, etc., which means that there are too many things running or too many programs to run. That's where memory comes in.

2. The classification of memory can be divided into dozens of kinds, mainly depending on what is divided, according to the memory chip, according to the number of gold fingers, etc., but what we encounter every day is according to the updated generation, that is, we often say DDR generation, DDRII second generation, DDRII third generation memory, the current mainstream memory in the market is three generations, one generation, two generations, and three generations are incompatible with each other, because their anti-misuse sockets are different, and there will be four generations and 5 generations in the future. Pure hand-played, I hope to help you.

The performance of memory depends on capacity, frequency, timing.

1. Memory capacity (the bigger the better).

A single 8GB memory cannot be lit on a P35 motherboard.

DDR2 was limited by the amount of memory supported by the motherboard at the time, and the maximum capacity of home-grade DDR2 memory was 4GB per stick. Residential-grade DDR3 memory, on the other hand, is limited by the manufacturing process, and it has a maximum capacity of 8GB per stick.

Note: If the memory is less than about 1GB, it will affect the response speed of the Win7 8 operating system, and different software and game application environments have different requirements for memory capacity.

2. Memory frequency (the higher the better).

The frequency of DDR3 memory can reach 2666+MHz

DDR2 and DDR3 use double data rate technology. DDR2 memory starts at 400MHz and can reach up to DDR2-1066 or even DDR2-1200MHz. DDR3 memory starts at 800MHz and can even reach a frequency of 2666+.

3. Timing (the lower the better).

The time series represents the time period it takes for memory to complete a job, and the longer the time, the less efficient the execution. The timing of DDR2 memory is CL5 CL6, while DDR3 memory is CL9 CL11. Overall, the higher the frequency of memory timing, the greater the memory latency.

There are two types of memory.

RAM, or Random Access Memory, is a memory that exchanges data directly with the CPU, with the advantage of being a block of read and write speeds, but data is lost after a power failure, and is usually used as a temporary data storage medium for the operating system or other running programs.

ROM, or read-only memory image, is used to write read-only image files, usually to the system or software. The feature is that the data is not lost after power failure, but the speed is slower than RAM. Sometimes it is also used to create storage space for mobile phones.
