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.
Determine the amount of calories you should eat by using the number of calories you used to eat to maintain your weight prior to your pregnancy and then add an extra 100 calories to support your pregnancy. For most women, 2,300 to 2,500 calories a day is a good range to aim for during the first 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.
