The number of logical processors (processors that the operating system and applications can work with) is (usually) greater or equal to the number of physical processors (actual processors on the motherboard). For example, a hyperthreaded processor with 4 physical processors will have 8 logical processors.
Usually, during the initial 6-months of pregnancy (that is 1 st & 2 nd trimesters), you will not have the need to consume more calories. This is usually about 2000-calories per day. On the other hand, the last 3 months of pregnancy (that is 3 rd trimester), you need additional 200 to 300-calories, which makes it to 2200 to 2300-calories per day.
For instance, in the first trimester, a pregnant woman does not need any extra calories at all. In the second trimester, you should try for an additional 340 calories a day to support your baby's development. During your last trimester of pregnancy, an optimum caloric intake would be increase to the 450 calorie range. This would equate roughly to eating a serving of lowfat Greek yogurt (120 Calories), two pieces of whole wheat toast (150 calories), and about 25 almonds (173 Calories).
