What Happens to Data Stored in Volatile Memory During a Power Outage?

The two types of memory that are used in computers are the non volatile memory and volatile memory. It is a well-known fact that volatile memory does not store data when power is not supplied to it. On the other hand, a non volatile memory can store data and files even when there is no power being delivered to it. To answer the question simply, data is lost in a volatile memory and loses power supply. But the explanation can be more complex than you think. In this article, you will learn about volatile memory and its counterpart, non volatile memory, and how they interact with one another, especially in cases of power outages. 

Volatile and Non Volatile Memory in Cases of Power Outage

Volatile memory 

An example of a volatile memory is the Random Access Memory of a computer. You can rely on this key component, just like the non volatile memory to function as directed and as expected. Its main job is to store files readily and move them accordingly based on the needs of the computer. This means that it takes less time to store it and it also utilizes its capabilities to support the computer to be as precise and as accurate as it needs to be. The consequence of using volatile memory is that it does not retain data when it loses power. The computer depends on the non volatile memory to save the data even during a power outage. 

Non volatile memory

Another component that is important in the computer is non volatile memory. It serves as the part that saves and stores files permanently even when no power is supplied to it. During a power outage, when the computer stores the data to the non volatile memory, the files will not be lost. It will still keep all the data until retrieved again when power resumes.  This is the reason why files are often transferred to the non volatile memory multiple times during operation so that you can keep the data as needed. 

Use of additional power supply

To get around the incapabilities of the volatile memory and its loss of data during a power outage, you can secure it by using an additional power supply that is separate from the main power line. It will keep the computer running even when power failure ensues. This is a crucial component incorporated by companies that cannot afford to lose data during a power outage. You can install generators and other power supply lines to keep the volatile memory functioning during power failures. 

Use of UPS 

Another solution to the problem of power outages is the use of an uninterruptible power supply or UPS. This is a cheaper solution for those who want to protect their data during power failure. You can install this in between a computer and a power source so that it still keeps the computer running even when the power supply is cut. This is because it utilizes a battery to help the computer maintain its functions despite the loss of power supply. 

Conclusion 

In essence, a computer is made of different key components so that it will move and function as a whole. Without the important parts like the non volatile memory or the volatile memory, the computer will be left incapable of doing wondrous things. A computer depends on the interaction between each of the components so that when gathered together, they will act as one and function fully according to specs. In terms of power outages, the computer can use UPS or other kinds of power supply so that it can shut down properly and save precious data on the secondary storage.
