Introduction Computer operating systems have been around for more than half a century so there is not much to add to the definition. Whether you are in the software industry or the academia, I assume you know what an operating system means but in few words an OS is the piece of software that sits
Suppose that you have a remote Windows machine for example a virtual Windows machine in a test automation farm. You can use Windows remote desktop client to connect to that machine and monitor test automation progress. There should be no problem if you close the remote session if you are testing a background process however
If it happens that you are confused by comparisons like the ones listed below then you came to the right place so please proceed and read the entire article for a better overview: Multiprogramming vs multiprocessing Multitasking vs multiprocessing Multitasking vs multithreading Introduction In the context of computing and operating systems, one might encounter many
Got curious why it takes more time to invalidate a wrong password? When you login to your Windows 7 computer you might notice that it takes more time if you type a wrong password than when you enter the right login information. This could be annoying but if you know the reason why this happens
Please follow the steps below: Download Eclipse from: http://www.eclipse.org/downloads. For example pick: Extract the file Move it to opt Create a link Create a desktop entry Search for eclipse then move it to the tool bar Reference: http://colinrrobinson.com/technology/install-eclipse-ubuntu
The following procedure outline the detailed steps needed to install the computer vision library OpenCV on Ubuntu Linux: Prepare the environment Only if you want to use python Problems with libjpeg.so then You may need this Get OpenCV from: http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.1/OpenCV-2.1.0.tar.bz2/download Extract it to some directory for example OpenCV2.1 In order to fix the problem “error:
Introduction The concept of virtual memory in operating systems refers to extending the physical memory (RAM) to the hard drive so that running processes behave as if there is unlimited address space. Paging means dividing the running process into equally sized logical pieces called pages so that only requested pages at the current execution time
This tutorial is not about installing Linux on bare metal nor about dual booting along with Windows however we are going to do it the easy way. The magic word here is virtualization. We will run Linux on Windows using virtual machines. There are so many advantages of virtualization in general but this topic is
Why an OS has to schedule processes Processes or jobs competing for CPU are not of the same type or have the same level of importance. For example some processes are CPU bound while other processes are IO bound. In the later case when a process blocks for IO the OS should let other processes
Relatively speaking, retrieving data from hard disk drivers is always slow compared to CPU and memory access due to the mechanical nature of the magnetic disk. Disk arm movement is very expensive operation therefore operating systems use disk scheduling algorithms to reduce seek time. Below you can find a summary of some of the well
