single.dvi 48 Distributed Systems Distributed systems have changed the face of the world. When your web browser connects to a web server somewhere else on the planet, it is par- ticipating in what seems to be a simple form of a client/server distributed system. When you contact a modern web service such as Google or […]

While we identified
single.dvi 16 Segmentation So far we have been putting the entire address space of each process in memory. With the base and bounds registers, the OS can easily relocate processes to different parts of physical memory. However, you might have noticed something interesting about these address spaces of ours: there is a big chunk of

single.dvi 10 Multiprocessor Scheduling (Advanced) This chapter will introduce the basics of multiprocessor scheduling. As this topic is relatively advanced, it may be best to cover it after you have studied the topic of concurrency in some detail (i.e., the second major “easy piece” of the book). After years of existence only in the high-end
single.dvi 38 Redundant Arrays of Inexpensive Disks (RAIDs) When we use a disk, we sometimes wish it to be faster; I/O operations are slow and thus can be the bottleneck for the entire system. When we use a disk, we sometimes wish it to be larger; more and more data is being put online and

20 Paging: Smaller Tables We now tackle the second problem that paging introduces: page tables are too big and thus consume too much memory. Let’s start out with a linear page table. As you might recall1, linear page tables get pretty big. Assume again a 32-bit address space (232 bytes), with 4KB (212 byte) pages
single.dvi 6 Mechanism: Limited Direct Execution In order to virtualize the CPU, the operating system needs to somehow share the physical CPU among many jobs running seemingly at the same time. The basic idea is simple: run one process for a little while, then run another one, and so forth. By time sharing the CPU

Thus, operating systems will have challenges in providing security in dis- tributed systems, where more than one machine must cooperate. There are two large problems: • The other machines in the distributed system
