full attention to the keyboard input lacking the ability to handle more than one event at a time. The ideal solution to this problem is the seamless execution of two or more sections of a program at the same time. Threads allow us to do this. A process is essentially a "heavy" unit of multitasking: as an approximation, think of it as an "application" (though it can include 'background' or 'system' processes such as your battery monitor, mouse and keyboard server, PDA synchronization tool etc).

compared. Process Management, File Management, Memory Management, and Security are going to be compared between Windows, Linux, UNIX, and Mac operating systems. Every operating system is different and is interesting to see how every piece of software has the same outcome but has different procedures in between. Process management is defined as how the OS manages multiple programs running at the same time. A thread is a feature of an OS that enables parallel processing within a single process. UNIX

independently by an operating system scheduler. The scheduler itself is a light-weight process. The implementation of threads and processes differs from one operating system to another, but in most cases, a thread is contained inside a process. Multiple threads can exist within the same process and share resources such as memory, while different processes do not share these resources. In particular, the threads of a process share its code and its context . On a single processor, multithreading is

which is 0.221 hrs simulation time per batch. (Exhibit 2: Average time per batch of each station). As day 7 and day 8 have 0 job arrivals, we used day 1-6 figures to calculate the average time for each station to process 1 batch of job arrivals. Base on the average time taken to process 1 batch of job arrivals, we were able to figure out how many batches each machine can handle. day | number of jobs arriving each day | utilization of station 1, averaged over each day | utilization of station
