In respect to this, does Raspberry PI 3 have internal memory?
Re: How to increase memory of Raspberry pi 3 32GB will be the size of the SD card. You can use a larger one if you need to. However, 32GB is a lot. The Pi3 itself comes wtih 1GB of RAM, this is not expandable.
can I leave my Raspberry Pi 3 on all the time? No, leaving the RPi on all the time won't harm it at all. The RPi is designed to be an embedded device, and run in an enclosed space. Unless you have it somewhere stupid like an active dryer vent, your device should be fine.
Similarly, how do I add more storage to my Raspberry Pi?
No Need to Ever Run Out of Storage on Raspberry Pi
- Expand the filesystem.
- Connect USB storage (hard disk drive, SSD, etc).
- Switch to a lightweight distro like Raspbian Lite or PiCore.
- Remove packages to make space on an existing Raspbian install.
Can you use a Raspberry Pi without an SD card?
As the Raspberry Pi series of boards have no on-board/integrated eMMC or other non-volatile storage method, there is no way to boot Raspbian without a SD card or external hardware. Instead of using a SD card, you should consider creating a boot disk using a conventional USB flash stick.
