The term “volatile memory” refers to memory that stores data using an electric current. All data is wiped when the power is switched off. Non-volatile memory, which does not require electricity to retain its data storage state, is sometimes contrasted with volatile memory.
Which of the Following is the Most Common Type of Volatile Memory?
Random-access memory, or RAM, is the most prevalent type of volatile memory. For high-speed data access, computers and other electrical devices need RAM. RAM read/write speeds are often many times faster than those of a mass storage device like a hard drive or SSD. When a computer starts up, the operating system is loaded into RAM. When you open a programme on your computer or mobile device, it gets loaded into RAM in the same way. The operating system and running apps can operate substantially faster if they are loaded into RAM.
Because RAM is volatile memory, when the host device is switched off or restarted, all data saved in RAM is lost. When the device is turned on, the operating system must be loaded into RAM again. While this adds to the startup time, the “reset” provided by non-volatile memory is an effective technique to resolve any residual difficulties that may arise while the computer is running. This is why restarting a computer or electronic equipment is a reliable method of resolving frequent issues.
The most prevalent sort of volatile memory is system RAM, although there are several more. Some examples of volatile memory are listed below:
- System RAM (DRAM)
- Video RAM (VRAM)
- Processor L1 and L2 cache
- HDD and SSD disk cache
NOTE: The phrase “volatile memory” relates to how data is lost when the power is switched off. It has nothing to do with the voltage required to keep the data alive.
