ABSTRACT

It is important to clarify that there are a number of practically essential stages in processing information which are formally irrelevant to measuring the effort involved. For example, supposing we are sending messages consisting of simple arithmetic formulae for evaluation and we have encoded the characters making up the written formulae as binary codes for ASCII. Suppose we’ve just received a message consisting of the bit sequence:

We know each character is represented as 8-bit ASCII so we separate out the individual codes:

Next we turn to a table of ASCII codes and their textual equivalences, as shown in Table 5.1. we look up each code in turn giving the character sequence:

1 2 + 2 3 * 3 4 ?
