| 6.4.2 | Frame format diagram
When you are working with bits, the most accurate diagram that you could use to visualize them is a voltage versus time graph. However, since you are usually dealing with larger units of data and addressing and control information, a voltage versus time graph could become ridiculously large and confusing. Another type of diagram that you could use is the frame format diagram, which is based on voltage versus time graphs. You read them from left to right, just like an oscilloscope graph. The frame format diagram shows different groupings of bits (fields) that perform other functions.
