Question: “How do I know how many bit systems are installed on a PC?” - occurs when installing new hardware or software. In the first case, you need to choose the appropriate driver. It should be with the same capacity as the system software. If this is not done, then incorrect operation of not only the installed equipment, but also other, older components, is possible. In the second case, the situation is similar only with the difference that failures will now be possible not in hardware, but in software.
What does it affect?
So, how do you know how many bit systems you have on your PC now? First, let's determine what this parameter affects. First of all, this is the maximum amount of addressable RAM. For x32 systems, this value is slightly more than 3.5 GB. If you put more such memory on the PC, then he simply won’t be able to see it, and therefore there will be no sense from it. Sometimes, instead of x32, the abbreviation x86 is used. This is not entirely true. In this case, x86 is a type of CPU architecture. It was named after the last two characters of one of its first processors - 8086. In turn, if an x64 system is used, then the maximum size of addressable memory in this case increases to 192 GB. The second important nuance is the number of bits of information that are processed per cycle. As the name implies, in the first case there are 32, and in the second - 64. From this, one more significant difference is obtained. A 64-bit system is capable of working with a 32-bit program. But on the contrary, it will not work to launch software. All these nuances are important to consider when installing and configuring various PC components.
Using OS
Now we will figure out how to determine how many bit system is in software using built-in tools. To do this, we need the “My Computer” icon. Moreover, its location does not play a special role. Consider this operation using the example of a shortcut located on the desktop. We hover over the mouse and make a single click with its right button. In the list that opens, select "Properties". In the "System Type" section, the information we need for the software component will be indicated. This is the answer to how to determine how much a bit system is at the OS level. This method is perfect for all the latest Microsoft operating systems.
Specialized software
You can get an answer to the question how to find out how many bit system is currently installed on a PC using a small free program “CPU-Z”. This software must be downloaded on the Internet. Then the program must be installed. In the window that opens, go to the "CPU" tab. Here, in the “Specification” field, our question will be answered. If “x86” is at the end, then this is a 32-bit architecture. But “x64” means that the system is capable of processing 64 bits per cycle. This is the most versatile way to find out how many bits a system is. It is great for all the most common.
OS today. The downside of this solution is that the hardware characteristics of the CPU are determined. It is possible that a 32-bit OS is installed on a 64-bit processor . Then it will give a distorted picture.
Summary
This material describes various ways to check how much a bit system is. To obtain a comprehensive assessment, it is recommended to use a combination of them. This will allow you to get a holistic picture of the capacity of the computer.
