Definition - What does Memory Capacity mean?
Memory capacity is the amount of memory that can be used for an electronic device such as a computer, laptop, smartphone or other smart device. Every hardware device or computer has a minimum and maximum amount of memory. The performance of a device and the efficiency of its input/output operations is dependent on memory capacity.
Techopedia explains Memory Capacity
The memory capacity of a device is commonly expressed in bytes, kilobytes, megabytes, gigabytes or terabytes. A device's memory capacity can be obtained from either the operating system or motherboard. In most cases, the architecture of the motherboard of the device influences the memory capacity of the machine. Certain third-party tools such as system-scanning applications can confirm the memory capacity of the device.
The memory capacity of a device depends on many factors such as the number of available address registers in the CPU. In the case of 32-bit CPUs, they can only address a memory capacity of up to 4 GB. As for a 64-bit computer, the memory capacity is unlimited. Operating systems also influence memory capacity. The memory capacity of a device is dependent on the main memory storage, random access memory and any external memory enhancement possible. Primary memory is often volatile while secondary memory is non-volatile.
