Does the amount of memory I see in the My Computer properties reflect the real memory value?

This is the total amount of memory, both used and unused.

The computer's running memory.

is made up of the motherboard. CPU, etc., as long as the computer itself supports it, it can be replaced.

1. The memory frequency is determined by the first: The memory module itself determines its default working frequency when it leaves the factory.

2. The memory frequency is also determined by the motherboard: in the past, computers were mostly determined by the motherboard chip, such as Intel.

The CPU with the LG775 interface does not integrate a memory controller, so just look at the memory type and frequency supported by the motherboard.

3. Determined by the CPU: Intel's new i5 car i7 (with LG1156 and LG1366 interfaces) processor is determined by the CPU due to the integrated memory controller. AMD, on its part, has integrated a memory controller from the K8 architecture, so it's up to the CPU.

The speed at which the computer runs and how many programs it runs.

The landlord can refer to the following paragraph.

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

The memory is composed of memory chips, electric wax boards, gold fingers and other parts.

Virtual memory is also known as virtual memory

memory）。All programs running on the computer need to be executed through memory, and if the program is large or numerous, it will cause the memory to be exhausted. To solve this problem, virtual memory technology is used in Windows, that is, a portion of the hard disk space is used as memory usage.

When the memory is depleted, the computer will automatically call the hard disk to act as memory to relieve the strain on memory. If the computer lacks RAM to run programs or operations.

RAM physical memory), then.

windows

It will be used to compensate. It combines the computer's RAM (physical memory) and the temporary space on the hard disk. When RAM (physical memory) is running slowly, it moves data from RAM (physical memory) into a space called a "paging file".

Moving data in and out of a paging file frees up RAM (physical memory) to get work done.

Generally speaking, the more RAM (physical memory) a computer has, the faster the program will run. If your computer's speed is slowed down due to the lack of RAM (physical memory) available space, you can try to compensate by adding virtual memory. However, computers can read data from RAM (physical memory) at a faster rate than from hard disks, so expanding the RAM (physical memory) capacity (with memory sticks) is the best option.

Physical memory, in an application, is naturally the size of the capacity of a memory module that is physically inserted into the motherboard's memory slot, as the name suggests. Physical memory is one of the most important resources on a computer. Windows' memory manager is responsible for allocating memory to active processes, device drivers, and the operating system itself.

Because the vast majority of systems have access to far more data and data than physical memory, physical memory is essentially the window through which the data runs. So memory capacity has an impact on performance, because if the process or operating system needs ** or the data doesn't exist, the memory manager needs to read it from disk.

The physical memory of a computer is commonly known as a memory module (currently there are mainly DDR2 and DDR3), and virtual memory is actually a space on the hard disk for memory use. Since hard drives are much slower than memory, ensuring enough physical memory is an effective way to speed up your computer.

Memory: Internal memory, equivalent to a kitchen board.

Memory refers to the temporary data storage point of the processor connected to the motherboard, and all the instructions that the processor reacts to are allocated by memory.

Memory is relative to the hard disk, that is, the data on the hard disk is temporarily stored in the memory, which is quite the same as if you take a wooden bucket to the river to get water, the water in the river is the hard disk, and the water in the bucket is the memory.

The word memory can be known from the surface of what it means, internal storage.

Generally, it is called a memory module, not a memory card, and it is a physical object.

Memory is the main component in a computer, and it is relative to external memory. The programs we usually use, such as windows98 system, typing software, game software, etc., are generally installed on external memory such as hard disks, but only this can not use its functions, they must be transferred to the memory to run, in order to really use its functions, we usually enter a piece of text, or play a game, in fact, are carried out in memory. Usually we store a large amount of data to be stored permanently in external memory, and put some temporary or small amounts of data and programs in memory.

Memory is divided into DRAM and ROM, the former is also called dynamic random access memory, one of its main features is that data will be lost after power failure, we usually refer to this kind of memory; The latter is also called read-only memory, we usually start the BIOS program stored in the ROM on the motherboard, and then it calls the windows98 or windows95 system in the hard disk, one of the main features of the ROM is that the data will not be lost after power failure.

Memory is the scratch body of processing, and the speed depends mainly on the CPU, followed by memory.

Computer memory refers to the size of a memory module; There is a substance; The size of the memory will affect the processing speed of the computer, and if there are too many open running programs, such as insufficient memory, it will cause a crash.

Computer memory refers to the "memory module" on the motherboard.

Memory sticks are physical items one by one.

Memory is used as a place to exchange data when an application reads and writes data, without which the computer cannot function properly!

The speed of the memory module itself has a fast or slow area, but the most important thing that determines the network speed is the bandwidth of the network, which has little to do with memory. All things like other hardware, the more memory you have, the faster your computer will run!

What is memory? There is a very important part of the structure of a computer, which is memory. Memory is used to store programs and data components, for the computer, with the judgment guess memory, there is a memory function, in order to ensure normal operation.

There are many types of memory, which can be divided into main memory and auxiliary memory according to their use, the main memory is also known as internal memory (referred to as memory), and the auxiliary memory is also known as external memory (referred to as external memory). External memory is usually magnetic media or optical discs, such as hard disks, floppy disks, magnetic tapes, CDs, etc., which can store information for a long time and do not rely on electricity to store information, but it is driven by mechanical parts, and the speed is much slower than that of CPU. Memory refers to the storage parts on the motherboard, which is the part that the CPU communicates directly with and uses to store data, and stores the data and programs that are currently in use (that is, in execution), and its physical essence is a group or more groups of integrated circuits with data input and output and data storage functions, and memory is only used to temporarily store programs and data, once the power is turned off or the power is off, the programs and data will be lost.

Since memory is used to store data and programs that are currently in use (i.e., in execution), how does it work? The so-called "dynamic" in dynamic memory refers to the fact that when we write data to the DRAM, the data will be lost after a period of time, so an additional circuit is required for memory refresh operations. Here's how it works:

Whether a DRAM memory cell stores 0 or 1 depends on whether the capacitor has a charge, with a charge representing 1 and an uncharged representing 0. But after a long time, the capacitor representing 1 will discharge, and the capacitor representing 0 will absorb the charge, which is the reason for data loss; If the power is greater than 1 2 of the full charge, it is considered to represent 1, and the capacitor is fully charged; If the amount of electricity is less than 1 2, it is considered to represent 0 and the capacitor is discharged to maintain the continuity of the data.

From the moment there was a computer, there was memory. The development of memory has also undergone many technical improvements today, from the earliest DRAM to FPMDRAM, EDODRAM, SDRAM, etc., the speed of memory has been increasing and the capacity is also increasing.

The CPU, that is, the processor, is responsible for processing the compilation of software, so that the computer hardware can cooperate with it and produce effects (such as visual effects - CPU processing - display - display images).

10% CPU usage means that the current CPU processing software is only 10% of the capacity of the software, which means that it can continue to process such a program with 9 times the workload.

Memory, which is divided into virtual memory and hard disk memory.

Hard disk memory is the size of what the computer can hold, and the hardware is used as the carrier to complete the memory on it, and it will not be lost unless there are special circumstances. Size like 500g, 1TB and the like.

Memory usage 10% This is talking about virtual memory, virtual memory, as the name suggests, is the space that does not actually exist, it is like our brain's temporary memory, that is, you can write down the general content at a glance at this Facebook, and you can use these notes to operate the computer, but you can't fully remember it (complete memory depends on the hard disk). That is to say, the virtual memory is alive, and the things you write down can be flexibly used to run software, but the size of the virtual memory is limited, there are 1G, or even 2G.

10% memory usage means that 10% of what you are currently writing or using in the virtual space (usually in the C drive, which is the so-called temporary file) accounts for 10% of your "brain", and you can still remember or use 9 such things.

We don't know how much memory it is, but if your computer is 2G memory, 10% of it means that it uses about 200M. You can buy the memory yourself, as long as the motherboard supports it, you can plug it in and use it as much as you want. There are so many types that I can't say them all.

I'm using Apacer's now.

Let me use an analogy, if you compare the entire computer system (including hardware and software) to a road, the CPU is the rated pressure that can be carried, and the memory module is the width of the road surface. The CPU usage is equivalent to the pressure being exerted per unit area, and the memory usage is equivalent to the traffic flow and ** driving at the same time across the lateral width of the road surface. Of course, the CPU will run in the corresponding level of cache according to the importance of the data when processing the data, just like a car with different weights must be driven on the corresponding road, and if it is not in accordance with the regulations, the system will issue a warning.

Racing occurs when the number of vehicles driving on the same section exceeds the maximum capacity that can be accommodated, like a "crash", (including the virtual memory drawn by the system, i.e., the spare lane).
