Technically, a computer is a programmable machine. This means it can execute a programmed list of instructions and respond to new instructions that it is given. Today, however, the term is most often used to refer to the desktop and laptop computers that most people use. When referring to a desktop model, the term "computer" technically only refers to the computer itself - not the monitor, keyboard, and mouse. Still, it is acceptable to refer to everything together as the computer. If you want to be really technical, the box that holds the computer is called the "system unit."

1.	What is CPU?	a	This term is pronounced like "cash" -- not "catch," and definitely not "cashé." There are many different types of caches but they all serve the same purpose
2.	What is Cache?	b	Stands for "Central Processing Unit." This is the pretty much the brain of your computer. It processes everything from basic instructions to complex functions.
3.	What is CRT?	c	Stands for "Computer-Aided Design." Also known by engineers and architects as the best invention of all time. Today, CAD software is used for nearly all three-dimensional designing.
4.	What is CAD?	d	Stands for "Cathode Ray Tube." CRT is the technology used in traditional computer monitors and televisions. The image on a CRT display is created by firing electrons from the back of the tube.
5.	What is CMOS?	e	Stands for "Compact Disc Read-Only Memory." A CD-ROM is a CD that can be read by a computer with an optical drive. The "ROM" part of the term means the data on the disc is "read-only,"
6.	What is Cursor?	f	Stands for "Complementary Metal Oxide Semiconductor." This technology is typically used in making transistors.
7.	What is CD-ROM?	g	The cursor on your screen can indicate two things: 1) where your mouse pointer is, or 2) where the next character typed will be entered in a line of text. The mouse cursor is most often an arrow.
8.	What is Buffer?	h	The computer term "bit" comes from the phrase "Binary DigIT," which is different than that thing you put around a horse's mouth. A bit is a single digit number in base-2 (a zero or a one)
9.	What is Bit?	i	A byte is a set of 8 bits that represent a single character in the computer's memory. Do not confuse this term with "bite."
	What is Byte?	j	This is a small amount of data that is stored for a short amount of time, typically in the computer's memory (RAM). The purpose of a buffer is to hold data right before it is used.
