## 1. Which Django field should be used to store an uploaded file of any type?

**Answer**

FileField is the standard field for storing any file type in Django. It automatically handles filesystem storage and saves the relative path in the database. This field requires configuring MEDIA_ROOT to define the physical storage directory.

## 2. What is the main difference between FileField and ImageField?

**Answer**

ImageField inherits from FileField and adds automatic validation to ensure the uploaded file is a valid image. It checks file headers and can extract image dimensions through width and height attributes. It requires the Pillow library to work.

## 3. Which settings.py parameter defines the base directory for uploaded files?

**Answer**

MEDIA_ROOT defines the absolute path to the directory where Django stores user-uploaded files. This parameter must point to a directory with write access for the application. MEDIA_URL defines the public URL to access these files.
