I feel like I'm starting to get into the swing of things with studying again. If I'm honest I didn't fully know how I'd get on having been out of any sort of academic learning for over 10 years but I have to say I'm enjoying applying myself to something new. However, I'm aware it's still early days with the truly complex material a long way off!
- To know the main components that make up an operating system
- To understand the boot process of an operating system
- To be able to install an operating system
- To create a file using the Windows and Linux operating systems
As part of this module I learnt the two main components of an operating system; the kernel and the user space. I learnt the kernel talks directly to hardware and is responsible for managing processes, files, memory and I/O, whereas the user space can be interacted with either through a GUI or a shell. I also now know that it's essential to understand commands in order to use shells such as Bash on Linux, as well as that logs record system events and can be used to identify errors.
The boot process was also explained to me from the computer being turned on and initialising the BIOS, up until the point the operating system loads the kernel to begin system processes. I then learnt how to install an operating system, the various installation media that can be used and how virtual machines can be created using applications such as Virtual Box.
In whole I found this module quite short and not too engaging; it was good to gain some basic knowledge around operating systems but the highlight for me was probably being introduced to Qwiklabs and seeing how I will be utilising it in my future studies. The next module is networking which I'm looking forward to as I know it will be a critical foundation for everything else to come.
