Advanced Documents - NCR PC4i Owner's Manual

HISTORICAL DATA
Diskettes in these manuals contain the software you're going to hear
so much about. In simplistic terms, software is like the old fashioned
telephone operator — it's the middle man — you talk via the keyboard
to the software — the software via firmware communicates with the
hardware — and then comes back to you with some response. Without
software you cannot communicate with your computer. There are
several types of software:
1. System Software, e.g., NCR-DOS
2. Program Development Software e.g., GW-BASIC
3. Diagnostics Software, e.g., User Diagnostics
4. Self-teaching Software, e.g., NCR PAL and NCR TUTOR
5. Application Software, e.g., specific use programs.
