These are notes/summaries that I took for ID1206 Operating Systems at KTH. The theory directory contains summaries from the awesome course book, "Operating Systems: Three Easy Pieces" by Remzi H. Arpaci-Dusseau and Andrea C. Arpaci-Dusseau. I highly recommend that book!
Please keep in mind that my summaries may not always be correct; if something sounds fishy, I might have misunderstood something. I recommend reading the course book as well if something sounded weird!
