Say an app has a download size of 3 GB, do you need 3 GB of memory or 3 GB of storage?
In: Technology
The downloaded app would be kept in the device’s storage. Memory is required to hold data temporarily, when it will be needed by the processor, so would rarely, if ever, need to hold the entire app at one time.
However, you may also need more storage than just the download size. The download file will be packaged, and probably compressed, so after unpacking and decompressing where necessary, it will need more space on disk. It might also create or retrieve more data after installation, adding further to the storage requirements.
