A computer is made up of many different parts, each with a specific function. Together, they ensure stable performance of the entire system as a whole. Many people say that the most important element is the processor, however, it is quite complicated. Speaking about its architecture, we often consider the processor core, since it is it that determines the capabilities.
Thus, the heap contains data in disorder, it has no order and may contain holes. From the point of view of the kernel, a process is characterized by its memory mapping, its open files and especially the state of the processor in this moment, which contains, among other things, a pointer indicating where the stack is and where the instruction is. The process memory map is being read.
To create a process, another process is needed. Rest assured it does not consume resources because there is no physical duplication, only in case of memory change that the content will actually be duplicated. The problem with a process is that it's a bit heavy, it involves memory rewrites, and above all it assumes the system is interacting with other processes. So there is another concept called flow.
Why is it worth considering the processor as one of the most important elements, especially when assembling? Because in many ways it is he who determines the quality and functionality computer as such. It is quite difficult for an uninitiated user to understand all aspects, even after reading the relevant literature, and the forums do not give an unambiguous answer at all, because they are filled with disputes as to which brand is better - AMD or Intel. And sometimes in these disputes the processor core and its functions and capabilities are not considered at all.
A thread is a breakdown of a process. This means that it uses exactly the same memory as the process, as well as the same file descriptors. What differs from one thread to another is only the execution and stack pointers, which means that 2 threads can execute different pieces of code from the same executable file and have local variables different from those of other process threads.
From the kernel's point of view, a thread is only characterized by the state of the processor within the process, so the kernel scheduler will see new record. Example of process memory in front of two threads. The difference, you immediately understood. From a programming point of view. To answer this question, we need to look at the processor.
If some points directly related to the operation of a particular processor can still be found on the forums, then specific characteristics must be considered for yourself. Manufacturers always provide such information in detail, unless, of course, it says something to the user.
Processor Specifications
Processor diagram. Transformers have, as you know, cores. The core is the part of the processor that does the work. Contrary to popular belief, most of what you do on a computer is not multitasking. Most users are running on dual core processors and after two to four processes you are no more multitasking. It's not that bad, and there's a reason you don't notice - those kernels are juggling your processes so fast that in human terms, the difference is imperceptible - and of course, when you do delay notification, those processes obviously go a little slower. , than usual.
Now the market is dominated Accordingly, the processor core, or rather their combination, determines performance in the first place. The main characteristic is the frequency of the processor, i.e. its speed and efficiency.
Advanced users are aware of the possibilities of overclocking the processor, i.e. increase its frequency. Almost any model can be increased productivity, however, not all will be effective. In other words, if we take two processors operating at approximately the same frequency, then they may have different overclocking potential. Therefore, the prospects and opportunities are different.
But processes and services are handled by the same processor, not by your operating system. The difference between a process is that it manifests itself in an application that you directly interact with, such as your web browser or instant messenger client. The service doesn't follow the same rules and usually runs outside of your direct interaction - always on antivirus, system clock, things like that.
So basically the difference between a process and a service is that you talk to one all the time, but you don't usually call each other often. You can manage your services by looking for services in the control panel and choose which services start and when they start. Make sure you don't touch a service unless it's causing you a problem, or if you know what you're doing - destroying vital services can crash your operating system and no one wants it.
As a rule, the temperature of the processor core becomes the main limitation, because as the frequency increases, the load increases, it starts to heat up, and this already has a detrimental effect on its condition. With prolonged operation in this mode, the processor core will begin to break down and fail, in the end, the chip will simply burn out.
The question you are asking is this. Previously, frequency was the most important feature for determining overall processor power. The rule is relatively simple: the higher the frequency, the faster processor. Since then, new technologies have emerged. Both companies offer completely different processors, each with its own architecture. As a result, each brand has its own advantages and disadvantages.
Therefore, we will compare the processors of each brand according to certain criteria. What is overclocking? This is a feature that increases the frequency of the processor beyond the base frequency so that it runs faster. Another important element to consider when choosing processors is integrated graphics.
However, it is wrong to focus on the frequency alone - the cache and bus frequency also have an important impact on the capabilities and final characteristics. The processor constantly processes various information, however, it does not come directly, but is stored for some time in the cache - an intermediate link between RAM and processor. The performance of the system very often depends on the speed of the cache. The bus frequency determines the speed of data exchange between the processor and the motherboard.
Electricity consumption
As for overheating issues. The processor cache contributes to computer performance because it allows the processor to temporarily store data for faster access later. To cope, every company offers power reduction technology in some of their processor models. These technologies work by reducing the speed of the processor when the processor is idle or unloaded.
High performance camera
Depending on your needs, you will choose the brand that matches your search criteria. In addition, the function of sending statistical information to Doctor Web has been implemented if it is allowed by the user. The scanning user interface has been improved. Localization has been added to the program in Estonian and Latvian.
Number of Cores
The notorious number of cores is now being actively discussed, because some say that the more the better, others, on the contrary, argue that it is better not to rush into big amount nuclei.
The most common options are dual-core models. Such chips have already begun to be introduced even into mobile devices, so it is difficult to surprise someone. The question arises, is it worth switching to quad-core or more processors? Now the situation is repeating itself, as with the introduction of the first multi-core models - the performance gain is actually not so big. Users don't know how to disable the processor core or force an application to use all the features, because not all applications are optimized for such models. At the same time, the increase in price is quite significant, but sometimes it is worth choosing a simpler, but also faster and more productive model, rather than chasing the number of cores.
If the "New version of the application" option is activated in the settings, the user is informed during the update anti-virus databases data available for new version, which can be loaded directly through the dialog. On our pages, we have often analyzed the panorama of programming and design, and also, above all, in terms of the accessibility of maps, determining the prevailing types and characteristics. Today we want to help you by helping you, or better yet, tell you what are 12 development boards that will make planning even easier.
Working with a development board can be tricky. If the software interface isn't complete or functional, if the card doesn't have the right number of I/Os, if the performance isn't comparable to what you need, then there are so many variables to consider when choosing one card over another.
