What is emulation? The emulation program. Emulation of a call - what is it?

Emulation is a copy of the original system that can function on another computer or equipment. The simplest example is the emulation of disks using the well-known DaemonTools program. Let's take a closer look at this issue. In fact, what is emulation, it is not difficult to understand, for this it is necessary to present the principle of its operation.

Computer Engineering

The easiest way to tell how the simulation works on computers, because it is used most often on computers, tablets and other equipment. Suppose you have a Canon scanner, and you want to emulate HP. Installs special software and programs designed for original HP devices that can work without problems on the same Canon. Exactly the same situation with most of the licensed drives that must be present in the drive of your computer or laptop while working.

So, images of these disks are created, which serve as a licensed product. This is how most gamers get to know what emulation is. But it should be noted immediately that the simulated device will work an order of magnitude slower.

The emulation program, or what to use to create an image

Currently, the problem is only what kind of program to choose. There are a lot of them, and most of the worthy options are posted on the net for free. For example, DaemonTools is really an effective utility that works without failures and does not take up much space on the hard drive. This software plan allows you to emulate several disks at once, in most cases you can create 3-5 drives, which depends on the version of the program. The Russian-language interface is simple enough and straightforward even for a beginner. In the main window, you need to add the previously created image and emulate it. There are other good programs, such as GizmoDrive, Alcohol 52%, etc. Despite the great choice, the principle of all utilities work is approximately the same, the main goal is to make the system think that there is a real, licensed disk in the drive.

Disk Emulation: An Overview of GizmoDrive

The main purpose of the utility is to mount files that have the ISO extension. In addition, another format that suits you can be used. The utility automatically creates the drive and inserts there an image that is displayed as a real CD / DVD disc. Here the most popular extensions are available for you, such as ISO, BIN, MDS, MDF and others. Also worth noting is a sufficiently large number of drives, a maximum of 26 pieces. To simplify the creation of images, a special manager is provided, which will help even a beginner to understand the work. Also Gizmo allows the user to create a GDrive image to emulate the hard disk of your device. Even compression and data encryption are provided here, which increases not only the performance, but also the level of file security. In principle, to understand what emulation is, along with such a simple utility as GizmoDrive, it will be extremely simple.

On the advantages of simulating

If we talk about emulating disks, then you will not notice the difference. The advantage is that for a licensed game you do not need to have a drive, but simply create an image. If you have exclusive equipment on one platform, then using a high-quality emulator you can use software on another computer, laptop, etc. A good example is the use of games intended for Xbox on the computer. Do not underestimate the importance of emulators in media art, where virtually all information is stored in digital formats. It is worth noting that creating an image allows not only to protect files from viruses, but also to save space on your hard drive. This is extremely important, if you work with large volumes of information, and the hard drive is not rubber, it has a limit.

Classification of emulation

Currently, the hardware platform is almost always used. But here there is one important point - you first need to get or emulate the operating system or hardware. This is done only once. Consequently, such simulators have virtually unlimited access to equipment. Often these are the usual layers of compatibility, which allow you to access a certain software or hardware. Again, for the Windows operating system this is one layer, and for Linux it's quite another.

There is also an emulation of the mathematical process that game developers use. It differs in that the most accurate programs for simulation (simulators) are used. In principle, this can be stopped and go to the next question. As you can see, as far as classification is concerned, there are many ambiguities for the average user, which you can only deal with in practice.

Simulate keystrokes

If you want to create your own audio file management widget, then you will need to use keystroke emulation. Currently, often enough imitation is used when testing various applications. If you have a program that allows you to control the audio system remotely, this is another reason to use the emulator.

I would also like to note that systems such as "smart home" also imply the use of remote access. In fact, keystroke emulation can be used anytime, anywhere, which is why it's extremely useful. Here it is necessary to use special codes, which differ from each other depending on the operating system used. As you can see, there is nothing complicated, the only thing to do is practice.

If you say briefly, then you can sit at work and manage your home computer or several of its functions (something like a remote, only with a large radius of action). True, you need to connect to the Internet.

A little bit about emulating the COM port

There are special programs that allow you to simulate the devices that are in your Com-port. The main task is to work with data packets. The utility customizes them using the RS232, UPD and other formats. As practice shows, Com-port emulation is used by developers of various applications with the purpose of testing them and checking for operability. Extremely useful function for people working on the network, for example, for network engineers. System integration is also greatly facilitated. Again, in simple words, you can check your system or some program without having a real device in the port. In principle, emulation of disks is somewhat similar in meaning, but some differences are still there. If you are a beginner, it is recommended to use a utility called COMPortDataEmulator. The Russian-language interface and convenient navigation through the menus help you quickly figure out what's what.

A few important points

Of course, one can not help but mention the emulation of devices running on "Android", as recently it is extremely important. You can use different programs, for example, Genymotion, which is quite simple, as well as stable and convenient. The "chip" from the manufacturer is that hardware acceleration of graphics is supported, and this is increased performance.

After you install the utility, you need to configure it, and you can start working. Emulation of "Android" is not much different from this game on this device, so most users use this kind of simulation. When you first start the program, you will receive a message stating that there are no virtual devices, so you need to create a new one. Then click Connect and authorize your account, which you have already created. Next, there is nothing complicated, find the game you want and press Play.

Conclusion

Here we are and you have seen almost everything that at least somehow concerns emulation. You might notice that the thing is quite useful. Even if your work does not require imitation or simulation of electronic systems, sooner or later it may even be very useful to you.

Now you already know a little about how emulation works, what it is and how to use it. The main thing is to understand the principle of action. Do not forget that before you create a disk image or something like that, you need to check your computer for viruses, because malware can completely ruin the image. After writing an image, do not throw away the disc, because you may still need it.

In principle, this is all that can be said on this topic. What is emulation and what it is needed for, you should understand. If you are going to use the information received, then start with simple programs, preferably in Russian.
