"If you go through a Kendall and Kendall's Book it shows Context Level and Zero "0" Level as a different level DFD. According to Book by James A. Senn Both are same.
So, Whatever method you follow just mention the reference you have taken from that book.
From my point of view James A. Senn's book have clear and Correct approach toward DFD."

The level 1, called context DFD, shows the whole system in one process. Level 2 focuses more closely on one particular process in level 1, and level 3 focuses on a single process from level 2.

a digital input accepts a voltage level between 0 ( zero and 5 volts + the digital circuitry is designed to accept a logic 1 or a logic 0 signal . the logic 1 is equal to 5 volts optimum , but a tolerance is allowed. the logic 0 signal is around 0 volts, to a limit of 0.8 volts. thus a digital signal is designed to be at 2 distinct points or levels of measurement. by comparison an analogue signal can be varying around a designed level. the input signal is likely to vary and the cirucit inputs are designed to analyse and measure these signals.
Mnemonics is a method of remembering things by associascation. Hexadecimal is a number system. 0-9 are as usual and then a(10) b(11) c(12) d(13) e(14) f(15)
The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.
dfd0 is a bigger scope in less detail than dfd1 which is much more detailed
A system diagram is known as a first level DFD (Level 0 DFD) A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system.
Contex level,0 level,first level DFDs for hospital management system
they are not different they are similar as level 0 DFD represents the primary individual process in system at highest level it is also called context diagram. It describes the overall system at highest level describing which element is inside and which element is outside the system..... youngheart_riwaj@yahoo.com

yes the questions is how to draw level 0,level diagrams for a computer based systems
It is measurement on an ordinal scale. Level 1 is less than level 2 which is less than level 3 and so on. But the difference between levels 1 and 2 is not related to the difference between levels 2 and 3, etc.
The difference is 1 .
The difference is 7.5 .
