History in Brief

Earlier, PCMCIA (Personal Computer Memory Card International Association) slots were used, where the PC card used to be mounted. These are now replaced by the Express/54 slot which is backward compatible with the Express/34 slot. This means that the Express/54 slot will not work on Express/34 slot, but an Express/34 slot will definitely work on an Express/54 slot. The latest HP laptops consist of these Express/54 slots. Wireless Internet cards that are used to access the Internet through the slots have an antenna on it to send data through the radio frequency bands.


A laptop needs some means for communicating with the Wireless Internet Access Points, and most of these perform the function through wireless Internet cards. In this type of connection, only the wired Ethernet connection is being replaced by the radio waves. These wireless connections convert the data into radio frequency to send them across a secured connection to a router or an access point. The current standard used is 802.11, which identifies the correct method to transfer the data across, and also helps multiple computers to connect through the same access point.

Without these encryption, it becomes easy for the hackers to barge into the wireless transmission. These eavesdroppers are restricted from the wired Internet connection due to the encryption of data in the 64 and 128 bit form. There are other new technologies that help improve the security of the connection, and are known as Wi-Fi Protected Access (WPA), where the data is not only encrypted but also has a peculiar security key that gets changed automatically over a period of time to adhere extreme security.

Thus possessing impressive advantages, these cards have helped the modern world to get rid wiring related issues and also gain an omnipresent secured Internet connection.
