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.
It is important to eat well. Depending on how old your nursing child is, you may need an additional 650 calories a day if he is under six months, or about 500 if he is now eating other foods. This is on top of the additional 350 (second trimester) and 450 (third trimester) calories you need during pregnancy.
