Laptops and Expansion Card Slots

A laptop computer has an external 68-pin slot that is 5 mm thick.
What type of expansion slot is this?
1. CardBus
2. PCMCIA Type I
3. PCMCIA Type III
4. >>PCMCIA Type II
Explanation : The expansion slot is a PCMCIA Type II slot. A 68-pin external expansion bus with a 5 mm opening is a Type II slot. Most PC Cards, which are expansion cards based on the PCMCIA standard, are Type II cards and will therefore be physically compatible with the notebook computer. This slot can be used with both Type I and Type II cards.

A Type I slot is a 68-pin slot, but is only 3.3 mm thick. This slot supports Type I cards only.

A Type III slot has 68 pins and is 10.5 mm thick. It supports Type I, II, and III cards. However, Type III cards are rarely seen, and very few notebook computers have Type III slots.

CardBus refers to a bus connection type that uses 32-bit bus mastering, not to the physical card interface, so this would be an inappropriate answer.
