TDEE = Total daily energy expenditure. How many calories you burn in a day. RMR = Resting metabolic rate (aka basal metabolic rate). How many calories your body burns just to sustain itself. If you were in a coma this is roughly how much you'd burn. TEF = Thermic effect of food. Your body burns a small amount of calories just digesting your food. EAT = Exercise activity thermogenesis. How many calories you burn while exercising. NEAT = Non-exercise activity thermogenesis. How much you burn on top of your RMR but isn't exercise. For example, walking around a retail store burns calories even if it isn't categorized as exercise. These are the four components of your metabolism (TDEE).
