Laptops and computer.

A lot of the modern desktops and laptops can be found in virtually every computer store and on sale in popular online retailers like
However, not all people may be willing to give up their older systems simply because they are satisfied with the performance of their systems. Others may not have the budget for buying the latest models.
One of the biggest reasons in replacing their older systems with the newer is to take advantage of built-in features like Wi-Fi and Bluetooth.

With many of the older systems having a few USB 2.0 ports, USB adapters can be purchased instead so their older systems can do things that the newer models can do. Here are some of the nice USB adapters that should work fine in any old systems with USB 2.0 ports.
Wireless USB Adapters
Only desktops that have special motherboards with built-in Wi-Fi can connect to a wireless router or other wireless devices. If not, an Ethernet must connect to an available Ethernet port of the wireless router in order to have wireless access. Older laptops may not have built-in Wi-Fi adapters either which leads to the purpose of Wireless USB adapters.
Average wireless adapters with 802.11g 54 Mbps can go as low as $20 while there are newer ones like the Linksys WUSB600N which features dual-band wireless-N that costs around $80 in With the diverse selection adding wireless capabilities is easy as long as the driver is compatible with operating system in use.
Bluetooth USB Adapters
Bluetooth USB adapters are just about the same size as the wireless USB adapters, but do not have an antenna. These adapters grant laptops and desktops to send data wirelessly to devices with Bluetooth. It is useful for connecting and syncing with phones and other mobile devices.
If the mobile has 3G and can connect to the Internet, the phone can share the Internet with the laptop so the laptop can access the Internet wirelessly playing the role of a Bluetooth modem.
USB 2.0 to DVI/HDMI Adapters
Even newer laptop models have DVI or HDMI outputs for connecting with the newest monitors and high definition TVs. Getting a VGA-to-DVI adapter is one way to bring that connectivity to old laptops, but a USB 2.0 to DVI/HDMI saves up the VGA slot and uses a USB one instead.
Some devices like the ARKVIEW USB-1612 Multi-Display USB adapter are better because of their support for multiple displays. It is recommended for the system to have at least 512 MB RAM to take advantage of multiple displays.
Plugging in any of these USB adapters pretty much makes the system as feature-rich as the average laptop or desktop being sold today. This means that a new system is needed if the hardware specs like the processor need upgrading.
