there is no difference!
A micro SD card is smaller in size and typically has a lower storage capacity compared to an SDXC card. SDXC cards have a higher storage capacity and are generally more compatible with newer devices that support the SDXC format.
Primary storage is usually the drive where the operating system is and the secondary storage is a additional drive for space. Usually, Windows names it's primary drive as C:\ and all it's following as other letters.
A buffer is a temporary storage location used to hold data during the transfer between two devices or processes. Buffers help smooth out the communication between these devices by compensating for any differences in data processing speeds.
Micro SDHC cards have a maximum storage capacity of 32GB, while SDXC cards can go up to 2TB. SDXC cards are generally more compatible with newer devices that support higher capacities, while SDHC cards are more commonly used in older devices with lower storage requirements.

SD, SDHC, and SDXC memory cards differ in their storage capacities and compatibility with devices. SD cards have a maximum capacity of 2GB, SDHC cards can hold up to 32GB, and SDXC cards can store up to 2TB. The main impact of these differences is that devices must be compatible with the specific type of memory card in order to use it effectively. Devices that only support SD cards may not be able to read SDHC or SDXC cards, limiting their storage capacity.
SDHC memory cards have a maximum storage capacity of 32GB, while SDXC memory cards can go up to 2TB. SDHC cards are compatible with devices that support SDHC and SDXC cards, while SDXC cards may not be compatible with older devices that only support SDHC cards.
Micro SD cards are smaller in size and have a maximum storage capacity of 2GB. SDXC cards are larger and can store up to 2TB of data. Micro SD cards are compatible with devices that have a micro SD card slot, while SDXC cards are compatible with devices that support the SDXC format.
MicroSDXC cards have higher storage capacities than regular microSD cards, making them more suitable for devices that require more storage space. If your device supports microSDXC cards, it is recommended to use them for better performance and storage capacity.
Some devices do not contain storage devices, or do not have enough storage space needed by a particular user. Extra storage devices such as an external hard drive can be utilized.
