Example text

This comes from the two-state, ON/OFF technology which is employed. So numbers have to be converted from base 10 (decimal) into base 2 (binary) before the computer can perform any arithmetic operations, or even store them. Perhaps unexpectedly, this transformation can be done by the computer itself using conversion routines. This is something like listening to French, but thinking in English. Binary numbers are laid out, as in decimal, using a limited number of symbols but extending their range by using ‘positional significance’.

Compilers are used to generate this binary for- Base 2 – the convenience of binary – 10110011100011110000 24 Stored program control – general-purpose machines 24 Instruction codes – machine action repertoire 26 Translation – compilers and assemblers 28 Linking – bringing it all together 28 Interpreters – executing high-level commands 30 Code sharing and reuse – let’s not write it all again! 31 Data codes – numeric and character 32 The operating system – Unix and Windows 36 mat from programs expressed in a more convenient manner.
