E. Motherboard: A motherboard by itself is useless, but a computer has to have one to operate. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port.

J. Microprocessor Chip (CPU) The computer you are using to read this page uses a microprocessor to do its work. The microprocessor is the heart of any normal computer, whether it is a desktop machine, a server or a laptop. The microprocessor you are using might be a Pentium, a K6, a PowerPC, a Sparc or any of the many other brands and types of microprocessors, but they all do approximately the same thing in approximately the same way. A microprocessor -- also known as a CPU or central processing unit -- is a complete computation engine that is fabricated on a single chip.

M. Tower: Refers to a computer in which the power supply, motherboard, and mass storage devices are stacked on top of each other in a cabinet. This is in contrast to desktop models, in which these components are housed in a more compact box. The main advantage of tower models is that there are fewer space constraints, which makes installation of additional storage devices easier.

N. USB flash drive: is essentially NAND-type flash memory integrated with a USB 1.1 or 2.0 interface. It is a small, lightweight, removable and rewritable data storage device of up to 64 GB, the most popular retail sizes being somewhere between 512 MB and 2 GB.
