THE SOFTWARE
Modern chromatographs are controlled by micro-
processors which require software containing infor-
mation on what they have to do. In most com-
puters, the software is divided into several levels:
BIOS
Operating system
Specific software.
BIOS
(basic input output system)
The
BIOS
matches the processor to its respective elec-
tronic environment. It contains elementary functions
which are typical for a specific application and which
always remain unchanged. Examples in the case of per-
sonal computers include e.g. output characters on
screen, recognize pressed keys. In the case of chroma-
tographs, these include e.g. selftest, receive control
software via interface, program flash
EPROM
.
Operating system
The operating system is a collection of programs which
control the more complex functions of the computer. In
the case of personal computers, these include e.g. for-
mat diskettes, interface control, print.
Specific software
These are the functions for which you have really pur-
chased a computer. For example, word processing with
personal computers, or valve control, data processing
etc. in the case of chromatographs.
