Steps to replace broken mobile device

Back up the data on your mobile device before starting a screen replacement. While a successful screen replacement should not threaten the data, it is a good idea to keep a backup in case a problem arises unexpectedly. Turn off the mobile device and disconnect it from all power sources. If the device uses a removable battery, remove it. Protect your hands and eyes before beginning glass replacement. If possible, carefully remove all pieces of broken glass. Consider using compressed air to remove any dust. Remove the display assembly. Refer to your device's documentation for information about removing the display. You may need a small, nonmagnetic screwdriver and/or metal or plastic tool to remove the assembly. If the display assembly is connected to the mobile device with a cable, carefully disconnect the cable. Unpack the new screen and connect it to the mobile device, connecting any necessary cables. Reassemble the mobile device, reconnect the power source and/or the battery, and turn on the device.

Practices gamers should practice to increase security

Before downloading any software or apps, including patches to games, or disclosing any private details, check the developer to be certain the website or the person making the request is legitimate. Read the permissions notices to learn what information is being requested or being collected. Avoid games requiring passwords to be saved to an online account on a smartphone. Exercise extreme caution if the game requires ActiveX or JavaScript to be enabled or if it must be played in administrator mode. Use a firewall and make exceptions to allow only trusted individuals to access your computer or mobile device when playing multiplayer online games. Do not share personal information with other gamers whom you meet online.

Review Hard Drive Files: regularly look at the most recent files and note any that are updated continually. These files might be the keylogging software's logs. Check Running Programs: periodically examine which software is loaded from the computer's hard drive into memory when you start the computer and which are running while you are using the computer. If you are uncertain of any program names, perform a search to learn the software's function and if it is a known keylogging program.

How a laser reads data on an optical disc

STEP 1 - a laser diode shines a light beam toward the disc STEP 2 -if light strikes a pit, it scatters, if light strikes a land, it is reflected back toward the last diode. STEP 3 -reflected light is deflected to a light sensing diode, which sends a digital signal of 1 to the computer absence of reflected light signal of 0

How a hard disk works

STEP 1 -the circuit board controls the movement of the head actuator and a small motor. STEP 3 -a small motor spins the platter while the computer is running STEP 4 -when software requests disk access, the read/write heads determine the current or new location of the data. STEP 5 -the head actuator positions the read/write head arms over the correction location on the platters to read or write data.
