What is RAM? What is a RAM disk and how to create one using SoftPerfect RAM Disk.

When we encounter unfamiliar combinations of letters, we begin to wonder what they mean. What is RAM, for example? You may come across this term often, but you can only guess about its meaning. It’s not surprising, since he came from the world of computer hardware.

RAM or what does RAM mean?

What is RAM? This is RAM (Random Access Memory) or random access memory. It is volatile and is part of the computer's memory system. It temporarily stores commands and data needed by the processor for them to carry out commands. RAM is addressable; each machine word has its own memory address.

Data exchange between RAM and processor

This exchange is carried out either directly or through ultra-fast memory zero level, if there is a cache - through it.

Your computer probably uses the second method. Based on the fact that memory is volatile, the data contained in it is accessible only when voltage is applied to the memory modules. Moreover, even a short-term loss of power to RAM can lead to damage (distortion) or loss of data.

Exist energy saving modes computer work, so-called “sleep” or “hibernation” (for window vents). Yes, they can significantly reduce the energy consumption of the device, but the RAM is completely deprived of power supply. How, then, is your data saved when you wake your computer from hibernation?

Yes, simply, data from random access memory are recorded on a non-volatile storage device ( HDD) V special file, and at startup the data from it is rewritten into RAM. The file itself is cleared upon restart, repeated hibernation (overwritten), you can simply delete it.

What is RAM memory for your computer? Temporary data storage, necessary programs, the kernel is usually loaded into it operating system. In other words, its size directly determines how many programs you can run simultaneously.

Traditional sizes for RAM ordinary users you can call it 2 gigabytes. Yes, Moore's law and so on... someone may have 16 GB installed, but the question is: are you sure that you need this amount of RAM?

For example: modern computer, equipped with 16 gigabyte memory modules, can perform the function game server some kind of MMO, online will be decent, we’ll limit it to 5,000 people.

I hope you understand what RAM means.

The technology that allows you to use part of the system RAM as an additional disk device has been known for quite a long time - since the early 80s of the last century. SoftPerfect program RAM Disk- one of the solutions to increase the speed of “heavy” applications on your PC and extend the life of your SSD. Logic dictates that this technology should be most widely used today, when RAM memory is cheap and plentiful.

But the facts say otherwise - few PC users know what a memory disk is and the benefits of its many advantages.

The main idea here is not only full use available computer RAM, but also in achieving significantly more high speed work - not in percentage, but in times.

RAM chips in modern PCs are often significantly faster than even ultra-high-performance SSD drives, which in turn are seriously ahead of classic magnetic HDD devices in this regard.

But RAM disks have one serious drawback - since the information stored on them uses volatile media (silicon chips), after a power failure (that is, after turning off the computer), this data ceases to exist.

Fortunately today there is simple remedies, such as SoftPerfect RAMDisk, which can be downloaded for free to solve this problem in a simple and elegant way. The program periodically records (and accordingly when the system is turned off) all information from the RAM device to a special partition systemic hard or solid state drive.

This way, RAM disks become highly independent with little loss of speed. And when combined with an SSD device, the issue of compromise is so small that it's not even worth mentioning.

By the way, in the context of creating and managing a RAM disk, it is no coincidence that I mentioned SoftPerfect RAM Disk. There are others on the Internet similar programs, for example qSoft RAMDisk Enterprise and Dataram RAMDisk, but SoftPerfect RAM Disk for Win 10 is one of the easiest tools to install, configure, and use.

After installing the application, you just need to select the “Add boot-mounted disk” option to specify the letter, size and format of the partition on your hard drive or SSD to which data from the RAM disk will be written.

Its size can vary depending on the amount of RAM available, as well as what percentage of it you are willing to allocate for use as an in-memory disk.

Most modern PCs have at least 4 GB of RAM, which makes them ideal for using SoftPerfect RAM Disk - in such a system you can safely allocate 20-25 percent of the available RAM.

SoftPerfect RAM Disk will take care of the rest, including the ability to create more than one virtual disk. After assigning a letter, the drive will appear in the menu Windows Explorer and you can use it like any other device in the system.

But how to benefit from such a disk? First of all, it can significantly speed up the loading of every program that uses temporary (cache) buffers - e.g. Adobe Photoshop.

The same applies to any web browser - if you configure it so that it uses the RAM disk as a buffer cache, it will not only work faster, but will also not clog up your hard drive with unnecessary temporary files.

RAM disks are also useful if you want to extend the life of an SSD device. Known fact, what after a certain number rewrite cycles solid state drives“wear out” and stop working. So if you're dealing with applications that love to constantly access disk device, redirect them to a RAM disk created using SoftPerfect RAM Disk - this way you will extend the life of the system SSD.

Have a great day!

All smartphones have a certain amount of memory, and this is one of the key points, which you should consider when purchasing a new phone. There are two types of memory: RAM (operational) And ROM (constant, internal). RAM memory, as a rule, has a smaller volume, and its purpose is to store information processed by the processor.

ROM memory belongs to the category long-term memory, and you can install the entire operating system, as well as applications and various files.

So, let's take a closer look at these two types of memory.

To understand what RAM is, you need to know what the acronym stands for "RAM". Translated from English this means "Random access memory", or also "Random Access Memory"(RAM). In other words, information in such memory can be read and written at any time, without having to wait for a series of processes to complete.

This significantly speeds up the search for certain data, since, unlike ROM memory or microSD memory, you can quickly access the physical location where the data is stored.

Features of RAM memory

RAM is the place that any device uses to fill with any data, for example, the operating system, applications used for their intended purpose and those that run in background. RAM is the storage from where the processor gets all necessary information directly.

That's why the RAM and processor are located on a single platform module, which is soldered to motherboard. In the image below you can see the Nexus 5X motherboard. This device has 2 gigabytes of RAM, a processor marked in red, and internal memory with an orange mark.

The more RAM memory is present in your phone, the better performance and the speed of the device as a whole, although this also depends on the type of memory and build quality of the phone.

Important point: RAM only works when the device is turned on - that is, this type of memory is not capable of storing information after the device is turned off. That’s why there is a slight delay when turning on the smartphone, during which the RAM is prepared to work with the device’s OS.

Types of RAM

Today there are many types of RAM memory, which differ in read speed and power consumption. The earliest reports of RAM appeared in the 60s of the last century, and since then, each new generation of RAM has been characterized by greater capacity, speed and energy efficiency.

Smartphones these days use a special type of RAM called LPDDR. Such memory consumes very little energy, on the one hand, but on the other, it is not cheap. The most common types of RAM are: LPDDR2, LPDDR3 and LPDDR4 - these are the last three generations of RAM for mobile devices. The main difference between them is that each subsequent generation sees a doubling of data transfer speeds.

What is ROM?

If RAM is read-write memory, then ROM is memory designed only for storing information. The abbreviation “ROM” is translated into Russian as “Read-only memory” (the domestic version is “Read Only Memory” (ROM). Data stored in such memory cannot be changed - by at least, this is not so easy or quick to do.

In newer generations of ROM, such as EPROM or Flash EEPROM (flash memory), the contents can be deleted and overwritten a large number of times, but such memory is still considered “read-only”. The main reason for this is that the erase and write process is relatively slow, and it can only be used for areas that have undergone the formatting process.

Today, ROM memory in smartphones is much faster than hard disks ordinary PCs, and modules with this type of memory are also mounted directly on the motherboard. This type of memory stores a special bootloader program that starts the device and loads the operating system, as well as the OS itself, all applications and user data.

As a rule, modified versions of the operating system also refer to ROM memory (such versions are also called “custom OS firmware”). Quick search online will tell you that there are many custom firmware options. Such firmware is called “ROM” because each of them represents a system image similar to the one recorded in ROM memory by the manufacturer.

Any computer consists of components, and each component performs some function. So, a hard drive is needed to store files; the video card generates an image that is displayed on the monitor display; processor executes mathematical operations, but RAM memory is needed to save intermediate results. Each of these nodes is, in fact, irreplaceable.

What is RAM memory

One of the most important elements of any computing system are random access memory modules. Sometimes they are simply called RAM. This abbreviation comes from the first letters of the English words Random Access Memory, which can be translated as “Memory with random access to any of its blocks” or, more simply, RAM (random access memory).

Physically it's small slats textolite, on which conductive paths are routed and microcircuits with sets of transistors - memory cells are soldered, and on one side there is a double-sided comb of sliding contacts, which allows you to connect modules to the corresponding connectors of the motherboard.

RAM memory is used to store data needed by all computer systems. Key Feature, which is worth remembering, is that after a reset or shutdown, all stored information from the cells is erased. When talking about what RAM memory is, it makes sense to draw an analogy with human thinking. For example, you need to add two numbers. A person retains one number in memory and, mentally substituting the second, performs a mathematical operation.

The “sheet” on which recording and calculation are performed is precisely an analogue of the computer’s RAM. The next day you may no longer remember the result. Of course, this is a very simplified model, but it is enough to understand.

IN computing systems From RAM, the processor selects data placed there by applications, and also sends processing results there, which are subsequently “taken away” by programs. That is why the term “operational” is used, that is, necessary for current operations.

Types of computer storage devices

Note that there is permanent memory- these are ROM chips, the transistors of which are capable of being in some kind of a certain state in the absence of voltage. Such microcircuits are installed, for example, in hard drives, routers, monitors (saving settings) and other devices where resetting the firmware is not allowed.

Sometimes the term “read-only memory” is used in relation to drives, but this is not entirely correct. You can easily verify this by asking the consultants at an electronics store not for a hard drive, but for a read-only storage device.

There is another modification of data storage solutions, which is a hybrid of RAM and ROM. So, custom settings The motherboard BIOS is stored in a microcircuit whose transistors are supported by a negligible current received from a rechargeable coin cell battery. This idea has found a “second life” in special drives, the data carriers of which are ordinary memory modules supported by a battery.

Modifications

There are several modifications of the RAM. The 386/486/Pentium systems used sticks designed in accordance with the SIMM and DIMM SDRAM standard. The operating frequency of the chips and bus ranged from 66 to 133 megahertz, the bit width was 64 bits (versus 32 for SIMM). With the increase in the performance of central processors and video cards, it was necessary to speed up the RAM, so data began to be transmitted at the fall and rise of the reference frequency, essentially doubling the bandwidth (DDR). Such strips use a voltage of 2.5 Volts and are now used only in specialized devices. More new modification DDR2 operates at 1.8 V and allows more data to pass through per unit of time than the previous standard. Approximately it can be assumed that high speed version DDR barely reaches the “regular” one from the updated version.

And finally, the most common standard today, DDR3, is capable of transmitting 4 data packets during each reference frequency period, which leads to an increase in bandwidth. However, additional delays were introduced for stability. 1.5 V is supplied to the modules for power supply. In general, the use of DDR3 in conjunction with modern processors more allows you to achieve higher system performance.

Problems and solutions

Very often in the configuration list you can find the following information: “RAM - 4 GB.” This means that one or more RAM modules with a total capacity of four gigabytes are connected to the motherboard. Is this a lot or a little for such an element as RAM? 4 GB is still quite enough to solve any problems, at least for the average user. On the other hand, this is already the one minimum required, without which normal operation operating rooms Windows systems Vista 10 is not possible.
Trying to use new systems with insufficient RAM may result in a message indicating that there is not enough RAM. RAM memory. Fortunately, this problem is easily solved. There is nothing complicated about how to increase RAM memory. To do this, you need to determine how many strips are installed. There may be one with 4 GB, or there may be several, but with a smaller volume. Depending on this, you will have to decide whether to simply add or completely change the RAM. Next, you need to determine how many free memory slots are on the board. It is best to see it “live” by removing the housing cover. All that remains is to either add more slats, or replace the existing one with more capacious model. It is important to take into account the standard of the installed RAM (DDR 1-3).

Question: What is computer RAM phone? What is RAM? What is RAM

Answer: RAM is a random access memory device. It can also be called “Random Access Memory”, short “RAM”, that is, random access memory for temporary storage of data, ensuring operation software laptop, computer, phone, tablet and other devices. Random access memory is also called "RAM", a more complete version of "random access memory". Each manufacturer may indicate differently in the device characteristics random access memory, RAM or random access memory, but the meaning is the same for everyone.

In this article I will explain in simple words so that any user can understand what is RAM, RAM or RAM and why it is needed on a computer, phone or other devices. Computer RAM or smartphone contains programs and operating system data also running application programs, as well as data from these programs. The number of simultaneously running applications, programs, tasks depends on the amount of RAM installed on the phone or computer. If there is not enough RAM in the device, then when running several programs or applications at the same time, there may be freezes and the device will think for a long time until the launched program opens. IN given time there are very powerful programs or games that require not only powerful processor, but also to have a lot of RAM, and even one such task can cause the computer or phone to freeze and you may have to restart the computer or phone yourself so that it works normally again.

On computers and laptop RAM You can increase it by purchasing RAM of the required amount, depending on the capabilities of the computer. You can also extract it already set bar RAM memory on the computer and replace it with a more capacious one. RAM on phones and smartphones on this moment You cannot increase, change or decrease since smartphones are more compact devices and it is better when choosing and buying a phone to look at the amount of RAM of the smartphone in the characteristics.

When choosing a computer, laptop, smartphone, tablet or other device, you need to pay attention to the characteristics of this device. If you are an active user and you want gaming computer or smartphone or you want to work with powerful programs, then it’s worth paying attention to RAM characteristics, RAM or RAM, depending on how the manufacturer or seller indicates. If you are a simple user, then you don’t really need to look at how much RAM is on your computer or phone, although large RAM certainly won’t hurt in any case except for the slightly expensive price.
