1). USB Flash DriveUSB flash drive or any other flash memory drive is basically an EEPROM that means "Electrically Erasable Programmable Read Only Memory".
USB flash memory sticks are nothing but an assembly of EEPROM, a controller with a RISC microprocessor, RAM and ROM. All of this interacts with a computer using a USB controller and connector.
Because USB sticks are EEPROM these can hold data for as long as 10 years.
2). Repairing a damaged CD
Why compact discs get damaged. Compact discs are all plastic. Compact discs are even not sensitive to magnetic fields as in case floppy disks, which never used to retain data when even a slight magnetic field is crossed with floppies. Then what is the reason why CDs get corrupted?
CDs work on the principle of reflection of light. CD drives have a built in laser that is used to read data.
3). Port Forwarding (what is port forwarding)
What is Port Forwarding
The term Port Forwarding is referred to the technique of forwarding a network port from one particular machine to another machine. This technique is usually applied when the receiving machine is behind a network router. By doing this, it enables users from outside the LAN (local area network) to reach a private user in the LAN itself.
