Wi-Fi wireless cards antennas LCD computer monitors CRT multi-core processors flash memory MacBook Air Asus Eee PC hard drive
In the early 21st century, Wi-Fi began to become increasingly popular as many consumers started installing their own wireless home networks. Many of today's laptops and desktop computers are sold pre-installed with wireless cards and antennas. Also in the early 21st century, LCD monitors became the most popular technology for computer monitors, with CRT production being slowed down. LCD monitors are typically sharper, brighter, and more economical than CRT monitors. The first decade of the 21st century also saw the rise of multi-core processors (see following section) and flash memory. Once limited to high-end industrial use due to expense, these technologies are now mainstream and available to consumers. In 2008 the MacBook Air and Asus Eee PC were released, laptops that dispense with an optical drive and hard drive entirely relying on flash memory for storage.
