In uniprogramming system, main memory is divided into two parts, one pare for the operating system (resident monitor, kernel) and one part for the program currently being executed. In multiprogramming system, the 'user' part of the memory must be further subdivided to accommodate multiple processes. The task of subdivision is carried out dynamically by operating system and is known as memory management . Memory management by OS can be divided into two methods:    # Real Memory Management In real memory management OS operates the space of the main memory only. There are two ways of real memory management. a) Mono Programming System:– Execution of one program at one time. The memory is divided into two parts, one is to save the OS and the other is to save programs. b) Multi Programming System:– Several simultaneous processes can be executed at the same time. Memory space is shared by several processes. To enable it to run a process should be stored into the memory. ...

Process scheduling is one way for a processor to handle n processes , by scheduling the execution process. Each process is executed one by one according to prescribed schedule. The aim of processor scheduling is to assign processes to be executed by the processor or processors over time, in a way that meets system objectives, such as response time, throughput and processor efficiency. In many systems, this scheduling activity is broken down into three separate functions: long, medium and short-term scheduling. Types of Scheduling  Long term Scheduling The long term scheduler determines which programs are admitted to the system for processing. Thus, it controls the degree of multiprogramming. Once admitted a job or user program becomes a process and added to the queue for the short term scheduler. In some systems, a newly created process begins in a swapped-out condition, in which case it is added to the queue for the medium term scheduler. Medium term scheduling  Medium te...

We can create attractive and eye catching website by using image slideshows, flash and other designs. There are so many pre-build JavaScript files and jquery plugins can be found on the web, but today i am going to tail about Creating simple and easy to understand code for image slideshow using JavaScript. Code for creating simple image slideshow  Just copy and paste the code below where you want to place slideshow and change the location of the images. <script language="JavaScript"> var i = 0; var path = new Array(); // LIST OF IMAGES path[0] = "image_1.gif"; path[1] = "image_2.gif"; path[2] = "image_3.gif"; function swapImage() { document.slide.src = path[i]; if(i < path.length - 1) i++; else i = 0; setTimeout("swapImage()",3000); } window.onload=swapImage; </script> <img height="200" name="slide" src="image_1.gif" width="400" /> Demo slideshow for the above code ...
