Boot Camp is a multi-boot utility included with Apple’s macOS (formerly OS X). It allows you to install Microsoft Windows on a separate partition of your Mac’s hard drive or SSD. Once installed, you can hold the Option (Alt) key at startup to choose between macOS and Windows.
Bootcamp 4.0.4033 is a specific iteration of the Windows support software (drivers) released by Apple. It is not the Boot Camp Assistant application itself (the tool that partitions the drive). Instead, it is the driver package that makes your Windows installation work correctly on a Mac.
