What does 2gb rom means in cellphone?

In a cellphone, 2GB ROM refers to the amount of built-in storage available for the operating system, applications, and user data. ROM (Read-Only Memory) in this context is typically flash memory that is not user-accessible like traditional ROM; it allows users to store apps, photos, and other files. While 2GB of ROM may be sufficient for basic tasks and lightweight apps, it can be limiting for users who require more storage for larger applications or media files.
