PPT-Memory Management We have seen how CPU can be shared by a set of processes

Improve system performance Process management Need to keep several process in memory Share memory Learn various techniques to manage memory Hardware dependent Memory management Memory management. We have also seen that complex exponentials may be used in plac e of sins and coss We shall now use complex exponentials because they lead to less writing and simpler computations but yet can easily be converted into sins and coss If has period 2 with Hybrid Memory Cubes.

The core of every computer is the Central Processing Unit. This directs the system to execute computer programs. In order to do this the computer needs access to:. Introduction. Multiprocessing.  is the use of two or more . central processing units.  (CPUs) within a single . computer . system. . The . term also refers to the ability of a system to support more than one processor and/or the ability to allocate tasks between them. Process – running program. Program is a static entity. Processes have resources, variables with values stored in memory, . etc. Processes can be started from the GUI or CLI. Some processes interact with users, others access disk files or system resources. Computer Systems. Lecture 6: Process Scheduling. Scheduling Basics. Simple Schedulers. Priority Schedulers.
