Bandwidth - This refers to how much data you can send through a network or modem connection. It is usually measured in bits per second, or "bps." A good analogy for bandwidth is a highway with cars travelling on it. The highway is the network connection and the cars are the data. The wider the highway, the more cars can travel on it at one time. Therefore more cars can get to their destinations faster. It's the same principle with computer data -- the more bandwidth, the more information that can be transferred at one time.
Baud - Contrary to popular belief, baud is not a direct measurement of data transfer speed, but instead it measures how many electrical signals are sent per second. Baud is used to measure the rate of electrical signals, or "signaling elements," for modems, networks, serial cables, and other data transfer mediums.
Bit - A bit is a single digit number in base-2 (a zero or a one) and is the smallest unit of computer data.
Byte - This is a set of 8 bits that represent a single character in the computer's memory. Do not confuse this term with "bite", as in taking a bite of a cookie, because that is totally different. Bytes are typically used to measure hard disk storage and computer memory (megabytes, gigabytes, terabytes, etc.).
