Expresscard modules are new technology that allows for the addition of hardware functionality to desktop and notebook computers. They are available in two sizes, with the smaller size having most applications. Expresscard technology offers easy adaptation and cost reduction, and has gained support from leading technology vendors.
The Expresscard module is a new technology that plugs into a computer system to allow for the addition of hardware functionality. The Expresscard was introduced by the Personal Computer Memory Card International Association (PCMCIA) in 2003 and is a thinner, lighter, and faster modular expansion for desktop and notebook computer users. Hardware features such as extra memory, wired and wireless communication tools, and security devices can be added by plugging these modules into the system.
The Expresscard module is available in two sizes. The Expresscard/34 is 34mm wide, while the Expresscard/54 is 54mm wide. The modules are both 5 mm high and 75 mm long. The 34 mm module has the advantage of being able to fit into the slot prepared for the 54 mm card, but not vice versa. The Expresscard simply plugs into a USB interface that is already built into most desktop and notebook computers.
All of the existing functionality of a PC Card will be available as an Expresscard, but using only half the size of a PC Card. The Expresscard will also have the power, heat dissipation and circuit board size to provide a range of extra applications, including multimedia applications such as television tuners, video capture and multiple monitors. It will also have storage facilities, such as solid-state (flash) and small magnetic and rotating micro-drives.
The Expresscard will also have adapters such as flash memory cards, as well as built-in security and identity sensors. Most of these apps will be built into the smaller 34mm size, but there are a few that will only be available in the larger 54mm size. Smartcard readers, some hard drives and Compact Flash readers are too large to fit into the Expresscard/34 and are only available in the largest size. Over time, as technology develops, it is hoped that all applications will be available for the 34mm size.
Expresscard technology offers users the computing benefits of the “sealed box” in the form of a PC card. Previously, adding hardware to a desktop computer required opening the computer with a screwdriver to add the new card. With Expresscard, you simply insert the card into an existing expansion slot. This makes adaptation easier and helps keep costs down. It is not necessary for computer manufacturers to ensure that there is adequate security and space inside the computer.
System developers have welcomed Expresscard technology with open arms because of the many benefits it offers. The cards combine expansion capabilities with higher performance, using less space. The technology also supports future implementations and high performance technology and helps reduce costs through standardization. The Expresscard has gained support from most of today’s leading technology vendors.
