A Wired LAN Network Ethernet PCI card is a expansion card which you install into a PCI slot on a motherboard on a desktop computer. A network PCI card lets you communicate with the internet, or your home wired ethernet network via a router, hub, switch or crossover cables  which are all connected via ethernet networking wires. A PCI network card is needed if your onboard network card breaks, or it is not compatible with your operating system like Windows, or Linux. A Network card can be installed  on a  older motherboard which does not have onboard networking ports for using broadband internet, or connecting to a wired ethernet network which is used to share and stream files and folders with other computers. a network can also be used to share hardware resources like a CD-ROM drive, printer, scanner, and hard drive space.
In this video, I’ll teach you how to remove your computer front panel from your computer case. Make sure your computer is powered off, and all the cables like USB cables on the front of your computer case are unplugged. You should also unplug all cables like video, speakers, USB, networking, and power cables from the back of your computer. It is best to work on your computer on a large flat table. Touch a metal part inside your computer to prevent static build up from damaging your computer parts. Be careful of sharp metal corners inside your PC case from cutting your skin.
All you have to do is open your computer case doors with a crosshead Philips, flathead or torx  screw driver to unscrew the side case door and front panel face plate screws holding your computer case to the front panel plate. Sometimes, there are plastic clips at the bottom or side of your computer case holding the front faceplate to the front of the computer case. You need to unclip the clips from your computer case to remove the front face plate from your computer case. You can use your nails, or a small flathead screwdriver to “gently” lift the clips off the clip holes on your desktop’s case.
Considering the arm and two phalanges that you may have to pay for the new Galaxy Nexus, it’s a good job that you can unlock the phone by simply smiling at the screen. Once the Google-endorsed smartphone has been unlocked, there are plenty of slick features to reassure you that your hefty investment has not been entirely in vain.
There’s been a lot of talk about the new Android 4.0 operating system – largely on account of its maverick moniker: Ice Cream Sandwich. The Galaxy Nexus is the first phone to be graced with this new improved OS. It features a freshly-designed Google font, is compatible with both tablet and mobile devices, and the Gmail service that’s incorporated into it has also been improved, including features such as the ability to search for content in emails while offline. In saying that, let’s not get away from the fact that the biggest USP of Android 4.0 is that it’s called Ice Cream Sandwich. Apple’s equivalent – iOS 5 – just can’t compete in the naming stakes.
