Physical Details
Note that a memory card's dimensions are determined while holding the card with contact pins upwards. The length of cards is often greater than their width. Most cards show a directional arrow to aid insertion; such an arrow should be upward.

Famous quotes containing the words physical and/or details:
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
“Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.”
—Willard Van Orman Quine (b. 1908)
