What is a PC card?

PC card, formerly a PCMCIA card, is a device for a peripheral interface used with laptop computers that use port cards. The slot, which was introduced at the beginning of the 90s. As the technology evolved, many types of peripheral devices were available in the card format to add laptop function. In 2003, the specification was renamed the form and port to the ExpressCard slot.

The card is the size of the credit card with the added thickness. Factor factor varies between devices and port development. The cards use a double range of 68 pins and are either 3.3 V or 5 V cards. The 3,3V cards have a protection function that prevents them from using only 5V in port. Some cards can work in 3.3V or 5V mode. The PC card falls into one of the three categories: Type I, Type II or Type III.

Type I cards work with a 16 -bit interface, they are 3 mm thick and were maines used forExtension of RAM or Flash memory. The type I card occupies one slot for a PC card, while most laptops of the day contained two slots or ports, one on the other side.

The

type II cards can be 16 -bit or 32 -bit and are 5 mm thick. These cards provided support in-a-a-out (I/O), which introduces the ability to add functionality to a machine that was not originally built. Modems and network cards are two examples. The II card often includes a dongle or a short wire with a full -size connector that is necessary for the card's thinness. The connector provides a connector for the necessary equipment, whether it is a telephone line, Ethernet cable or other interface.

other type II formats include an excess or strong outer end with a built -in connector. Although it is more comfortable than Dongle, this form can block the secondary port. Even more variations contain retracting antennaa rises to minimizeBusiness when the card is not used and protects the extensions.

PC PC type III can also be 16 -bit or 32 -bit and is thick 10.5 mm. These cards can hold connectors without the need for Dongle.

6 This data is revealed by manufacturers, model, type of card, energy requirements, supported options and other relevant information. If the machine does not recognize the card, one of the normal reasons is that the CIS file has been damaged or is missing.

Port card has enabled upgrade the notebook without opening it. If the internal component stopped working or became outdated, the PC card was the answer. From wireless modems to mobile broadband, from optical mouse to TV cards, maintained laptops flexible and expandable.

with the introduction of a faster slot for the expression card in 2003, the PCSE card slot became an inheritance. Until 2007, most notebooks were sent only with an express card slot or without a card slot from respect for a growing trend of using USB ports to secure Pthe driven function. In 2009, PCMCIA dissolved according to their website and turned any further development to the USB Implementators forum (USB-F).
