A Brief History of PCI and USB For Wi-Fi

First, a quick history lesson so you can understand the stories behind how PCI and USB Wi-Fi came to be.

PCI stands for Peripheral Component Interconnect. This standard was introduced in 1991 to provide a fast connection for add-on cards to communicate with a PC‘s central processing unit (CPU) and RAM. These dedicated PCI expansion slots live inside desktop computer cases.

When Wi-Fi wireless technology arrived in 1997 with the 802.11 standard, it didn‘t take long for hardware makers to offer PCI Wi-Fi cards. Sliding into PCI slots on motherboards allowed Wi-Fi signals to harness a direct path to a computer‘s main components for solid connectivity. By the early 2000s, PCI Wi-Fi cards provided a speedy way for desktops go connect wirelessly.

USB means Universal Serial Bus. Also debuting in 1996, USB was designed as an easy way to plug mouse keyboards, printers and other peripherals into small, standardized ports on computers. This plug-and-play convenience made USB a quick hit, and allowed later USB Wi-Fi adapters to bring wireless networking to laptops and PCs effortlessly.

Today, both PCI and USB Wi-Fi solutions thrive as simple ways of cutting the Ethernet cord across all types of desktops, laptops and devices.

Next, let‘s contrast the key benefits and limitations of PCI vs USB Wi-Fi when shopping for the best wireless network card.
