Virtual RAM, also known as virtual memory, is a memory management technique used by operating systems to provide additional memory to programs that require more memory than the system physically has available.
When a program is running and it requires more memory than what is available in the physical RAM, the operating system temporarily transfers some data from the RAM to the hard disk to create a space in the RAM for the new data. This temporary space is known as virtual RAM, which the operating system treats as if it were physical RAM.

Virtual RAM technology has several uses, including:
Allowing applications to run that require more memory than what is physically available: Virtual RAM technology allows operating systems to provide additional memory to applications that require more memory than what is physically available in the computer's RAM.
Improving system performance: Virtual RAM can improve system performance by reducing the amount of data that needs to be swapped between the RAM and the hard disk, which can improve application response times.
Running multiple applications simultaneously: Virtual RAM enables computers to run multiple applications simultaneously, even if each application requires a large amount of memory. This can be particularly useful for users who need to run several memory-intensive applications, such as video editing software or 3D modeling applications, at the same time.
Providing a safety net: Virtual RAM can act as a safety net in the event that the system runs out of physical memory. If a system runs out of physical memory, it can use virtual RAM to store temporary data, preventing crashes or freezes. However, using virtual RAM excessively can slow down system performance.

Virtual RAM and physical RAM are two different types of memory, and while they work in a similar way, they have different characteristics.
Physical RAM, also known as main memory, is the actual hardware in your computer that stores data and instructions for your CPU to access quickly. The speed of physical RAM is measured in MHz or GHz, and faster RAM can improve the overall performance of your computer.
Virtual RAM, on the other hand, is a technique used by the operating system to create additional memory by using a portion of your hard drive or SSD as if it were RAM. While virtual RAM can provide additional memory for your system, it is much slower than physical RAM, since data must be read from and written to the hard drive or SSD, which is much slower than accessing data from physical RAM.
In terms of performance, physical RAM is always faster than virtual RAM because it is a hardware component specifically designed for high-speed data access. While virtual RAM can provide additional memory, it is only used when the physical RAM is full, and the system needs more memory to run applications. If your computer has sufficient physical RAM to handle the applications you run, virtual RAM may not be used at all.

Let's say you are running a computer program that requires more memory than your physical RAM can provide. For example, you are running a photo editing software that is editing high-resolution photos, and the program needs 4 GB of memory to perform all the editing functions.
If your computer has only 2 GB of physical RAM, the operating system can use virtual memory to provide the additional memory required by the photo editing software. The operating system allocates a portion of the hard drive or SSD to create a virtual memory space, say 4 GB, which is then mapped to the physical memory in the computer's RAM.
When you run the photo editing software, the operating system loads the necessary data from the hard drive or SSD into the virtual memory space. As you edit the photos, the software will access and update data in the virtual memory space.
If the physical RAM becomes full, the operating system will move some of the data in the physical RAM to the virtual memory space, freeing up space in the physical RAM for new data. This is done transparently to the user and the running program.
While virtual memory can provide additional memory to the system, it is slower than physical memory since data must be read from and written to the hard drive or SSD. Therefore, excessive use of virtual memory can slow down system performance.
In summary, virtual memory is a technique that allows the operating system to provide additional memory to programs that require more memory than the physical RAM can provide. It does this by using a portion of the hard drive or SSD as a virtual memory space.
