Week three was in the first week
of October 2011. It was on Tuesday, 4 October 2011. We leant about
Software Layers: Operating System, Drivers, System Software, and Application
Program. At this chance, we needed to remember about Software Layers. It was
written that in Software Layers:
Computer User à Application à Operating
System à Device
Drivers à System
Software (Bios) à Computer
Hardware
Wow, it was difficult for me to remember that software
layers, we must remember because it will be out in the final exam. And for
Operating System function I learnt in this week. Now, I knew the types of
Operating System e.g :
o
Stand Alone – DOS,
Windows, Mac, Unix, Linux
o
Server –
windows Nt, Unix, Linux, Solaris
o
Embedded OS –
Windows CE, Palm OS, BB, Android
And for
Programming Language (PL) there were 2 types (Low-level and High-level).
Low level used computer language / number of binary. And for High-level used
machine independent. There were 3 generation of HLL (higher-level Languange) :
third, fourth, fifth-generation language. I was like: C++, Pascal, Java, VB. But
my teacher said you would study this programming language next semester or you
can join in ICT majoring.
