Flash memory is a form of EEPROM (Electrically Erasable Programmable Read-Only Memory) that allows multiple memory locations to be erased and/or written using electrical signals. It is a rewritable memory chip that, unlike a RAM(Random Access Memory) chip, power supply is not required to hold the contents. It is commonly used in memory cards, USB flash drives, MP3 players, digital cameras and mobile phones. Flash memory is also an example of a Non-Volatile Read Write Memory (NVRWM).

A motherboard is the main circuit board inside a computer that connects different parts of a computer together. It has sockets for the CPU, RAM and expansion cards and it also hooks up to hard drives, disc drives and front panel ports with cables and wires. There has been continuous innovative development in the area of motherboards with the bus speed increasing to a few giga bytes per sec and increasing connector density. Most widely used motherboards such as ATX, ITX are discussed.
