|volatile memory||nonvolatile memory|
|Definition||Volatile memory is the type of computer memory that is temporary in nature. It stores the data inside it only until power is supplied.||Nonvolatile memory is the type of computer memory that is permanent in nature. The data stored in that type of memory remains there even after the system is turned off.|
|Stored data||Volatile memory stores data for programs currently being processed by the CPU. Frequently used data and information about the process is stored in volatile memory.||Non-volatile memory stores data from the basic boot process of the computer system’s BIOS. All types of media and data that need to be stored permanently or for a longer period.|
|effects||Volatile memory has effects on system performance. The more storage space there is in volatile memory, such as RAM and cache, the more efficient system performance will be.||Non-volatile memory has effects on system storage. The more storage space, the more amount of data can be stored in the computer system and can be stored permanently.|
|Speed||Volatile memories are nature’s fastest memories. They contain frequently used data within them and the data is accessed faster than all.||Nonvolatile memories are relatively slow compared to volatile memories. Data accessed from non-volatile memory is slow compared to volatile memory.|
|Example||Common examples of volatile memory include computer RAM, cache, etc.||Common examples of non-volatile memory include computer ROM (secondary storage, hard drive), optical storage disks, flash memory, etc.|
Volatile Memory is the kind of computer memory that stores data temporarily. It is also referred to as temporary memory. The data in the volatile memory is stored only until the power is supplied to the system, once the system is turned off the data present inside the volatile memory is deleted automatically. RAM and cache of the computer system are the best common example of the volatile memory. Volatile memory due to its temporary nature its stores only the frequently used data. The data of the programs running on the processor is stored in volatile memory. It is quite fast and efficient in nature and can be accessed rapidly. Volatile memory is directly linked to the performance of the computer system. The more amount of volatile memory the more effective performance the computer system will possess.
What is nonvolatile memory?
Non-volatile memory is the type of computer memory that stores data permanently. Data stored in non-volatile memory remains there even after the system is powered off. Computer ROM is non-volatile memory. It is not as efficient and fast in nature as compared to volatile memory but stores data for a longer period. Non-volatile memory has basic system information inside it, such as boot process information, system boot information, and BIOS. Nonvolatile memory is slow to access. All data that needs to be stored permanently or for a longer period is stored in non-volatile memory. Non-volatile memory has a direct impact on the storage capacity of the system.
- Volatile memory is the temporary memory of the computer system.
- Non-volatile memory is the permanent memory of the computer system.
- Data from programs in process and frequently used data are stored in volatile memory.
- System information, BIOS, and all other types of data are stored in non-volatile memory.
- Volatile memory is fast and efficient in nature.
- Nonvolatile memory is slow and permanent in nature.
