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.
Second and Third Trimester. It is normal for pregnant women in their second or third trimester to be hungrier because their baby needs more fuel to develop at this stage. You will need an average of 300 extra calories a day to gain weight at a healthy pace while supplying enough energy to your growing baby. You can calculate your daily calorie need for these trimesters simply by adding an extra 200 calories a day compared to what you were eating during the first trimester.
