Memory Connectors - PC Card SocketsPC card sockets, also known as PCMCIA sockets, are connectors used to connect PC cards, also known as PCMCIA cards, to a computer or other device. PC cards are small, removable memory cards that were commonly used in laptops and other portable devices in the 1990s and early 2000s. They were used for a variety of purposes, including storage, networking, and expansion of the device's capabilities. PC card sockets are typically rectangular in shape and have a series of metal contacts along one edge for connecting to the PC card. They are designed to fit a specific type of PC card, such as Type I, Type II, or Type III, and are usually located on the side or rear of the device.
