Most people know what OS stands for, but do they really know what it does and how it works? From this interesting seminar about Operating System (OS), we learnt quite a lot about OS. Before this seminar, we only know that Mac, Windows etc are examples of OS, but we never really know how it functions until we’ve been through this seminar about OS.
OS actually operates in kernel mode, provides abstraction, manage hardware allocation etc. This is something that some of us might not know until we have been through this seminar.
The seminar starts off with some introductions to OS before moving on to brief history of OS on the first computer, ENIAC. From there we get a clearer picture of how program interacts with hardware, advantage, disadvantages etc. After that comes the common feature of mainframe, batch processing of IBM 360 etc.
One interesting topic about this seminar is perhaps how OS does process management. First Come First Serve is not a very good solution when many processes are queuing up, so Round Robin would be a better solution is this case where each process are only assigned a certain amount of time to process regardless of whether they finish their job and they will have to queue up again for their turn.
Another interesting part of the seminar is the king’s story to help us better understands how OS uses physical and logical memory. This gives us a better understanding of how OS performs a task.
This seminar is definitely beneficial to all its audience. After attending this seminar, we have a better knowledge of how OS works and of course, look forward to taking CS2106 in the near future.
