Gender identity disorder (GID) or gender dysphoria is the formal diagnosis used by psychologists and physicians to describe people who experience significant dysphoria (discontent) with the sex and gender they were assigned at birth. Evidence suggests that people who identify with a gender different from the one they were assigned at birth, may do so not just due to psychological or behavioral causes, but also biological ones related to their genetics, the makeup of their brains, or prenatal exposure to hormones.

Gender identity is a person's private sense and subjective experience of their own gender. This is generally described as one's private sense of being a man or a woman, consisting primarily of the acceptance of membership into a category of people: male or female. All societies have a set of gender categories that can serve as the basis of the formation of a social identity in relation to other members of society. In most societies, there is a basic division between gender attributes assigned to males and females. In all societies, however, some individuals do not identify with some (or all) of the aspects of gender that are assigned to their biological sex.

Genealogy (from Greek: γενεαλογία genealogia 'the making of a pedigree') is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members.

The results are often displayed in charts or written as narratives. Although generally used interchangeably, the traditional definition of 'genealogy' begins with a person who is usually deceased and traces his or her descendants forward in time, whereas, 'family history' begins with a person who is usually living and traces his or her ancestors.

Graphics Interchange Format or GIF are based on indexed colors, which is a palette of at most 256 colors. This helps greatly reduce their file size. These compressed image files can be quickly transmitted over a network or the Internet, which is why you often see them on Web pages. GIF files are great for small icons and animated images, but they lack the color range to be used for high-quality photos.

One gigahertz is equal to 1,000 megahertz (MHz) or 1,000,000,000 Hz. It is commonly used to measure computer processing speeds. For many years, computer CPU speeds were measured in megahertz, but after personal computers eclipsed the 1,000 Mhz mark around the year 2000, gigahertz became the standard measurement unit. After all, it is easier to say '2.4 Gigahertz' than '2,400 Megahertz.'
