To equip something means to give it the tools or supplies it needs to work properly.
When we talk about equipping a new employee at work, we mean giving them the necessary things like a computer, phone, and training to do their job. For example, if you just got hired as a teacher, your school would probably want to equip you with a classroom, textbooks, and teaching materials so you can get started right away. Similarly, when we talk about equipping a car for a long road trip, we mean loading it up with things like food, water, maps, and a spare tire, so the driver has everything they need on the journey.
To supply with something necessary in order to carry out a specific action or task; to provide with (e.g. weapons, provisions, munitions, rigging)
