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.
Most women need 300 calories a day or more during at least the last six months of pregnancy than they did before they were pregnant. But not all calories are equal. Your baby needs healthy foods that are packed with nutrients - not empty calories such as those found in soft drinks, candies, and desserts.
