Therefore, a soft real-time system can miss the deadline by one or two seconds. Batch operating system The users of a batch operating system do not interact with the computer directly. The management of all these devices affects the throughput of a system; therefore, the input and output management of the system is a primary responsibility of the operating system Scheduling Scheduling by an operating system is a process of controlling and prioritizing the messages sent to a processor. When trouble strikes, you can go into the Time Machine and recover previous versions of individual files or even the entire system.

This is where compatibility might be an issue, because we might find that hardware that we currently have does not have the corresponding 64-bit drivers. Examples of operating systems that would fall into this category are: Multithreading - Operating systems that allow different parts of a software program to run concurrently.

This is very helpful for small-scale industries and businesses that require communication round-the-clock. The improved user interface gives it a Windows-like look and feel, and is a big part of its appeal. The main difference between Multiprogrammed Batch Systems and Time-Sharing Systems is that in case of Multiprogrammed batch systems, the objective is to maximize processor use, whereas in Time-Sharing Systems, the objective is to minimize response time. I don't recall whether we actually completed the ports -- probably not, given the state of things in the office. And one of the items I discovered hidden in the demos was a little gem called Dogfight. Most importantly, you must have the knowledge of machine programming. Clean installation is sometimes also called Custom installation. So as years went by, the machine User interface became more and more user friendly. These types are targeted for individuals operating at various levels. Operating System: What is it? The files or icons can be opened or closed by clicking them with a mouse button. But you can't back up and recover an entire system that way.

Different Versions of Windows Operating System - Nowadays operating system has become very popular as it can be found on several devices ranging from personal computers to cell phones, particularly the smart phones.

Before you start Objectives: familiarize yourself with the terms and common procedures when dealing with Windows installations. Prerequisites: you have to be aware of various available. Key terms: operating system installation, Windows installation, clean installation, in-place upgrade, migration, dualboot, installation source. Clean Installation To do a clean install we can either wipe out an existing operating system on existing partition and then install Windows, or we can install Windows on a brand new partition. When we do a clean install on the new computer, we can copy our existing user data to the new computer after the installation. After that we can install any applications that we need to run within our new installation. There is a way in which we can preserve our old Windows installation when doing a clean install. Instead, we will choose a new installation. In this case, our new Windows will be installed to a new directory, leaving our old installation of Windows intact. Existing operating system files will be copied to a folder called Windows. After the installation we can migrate our user data to the new installation and reinstall any our applications. We can use Windows Easy Transfer to transfer all user settings and data from the old installation to the new installation. If we do a clean install on the same computer as our existing computer, we have to save user data and files before performing the installation. Of course, during install we can also choose to reformat partition on which we want to install new Windows. In this case we delete all system files and all user data from our computer, and then install new version of Windows. Clean installation is the most recommended method for Windows installation. Clean installation is sometimes also called Custom installation. In-Place Upgrade The second type of installation is In-place upgrade. An in place upgrade takes an existing installation of Windows and upgrades it to a new installation. Our existing installation of Windows is overwritten with the new installation of Windows. In-place upgrade will maintain all of our users, applications, settings and files. New version of Windows is reconfigured to be aware of our data files and any applications were installed. We should also disable antivirus software because it can interfere with the installation process. Note that using this types of windows operating system our old operating system installation is no longer available. Typically, we can only perform an in-place upgrade to the next higher version of Windows. If our new version is two versions away from our old version, we will typically have to do a clean installation. We can only upgrade 32-bit to 32-bit, or 64-bit to 64-bit operating system. When it comes to Windows editions, we can perform in-place upgrade from one edition to another as long as we are moving up in editions. Since all applications are preserved we might have application compatibility issues, so we have to check our applications against a new Windows installation. Migration The third way to install Windows is a migration. A migration involves two Windows installations. One Windows installation is the source and other is the destination. What we want to do is migrate user files and settings from the source to the destination installation. Migration can be performed either using the Side-by-side or Wipe and Load method. Side-by-side migration is used when Windows installations are on different computers. Wipe-and-load method is used when we only have one computer. If that is the case we can temporarily upload user settings on some other computer, wipe out existing computer and than do a clean install on that computer. After the installation we can download saved settings from previous installation to complete the migration process. To do migration we can use User State Migration Tool or Windows Easy Transfer. Dualboot Dualboot or multiboot refers to a computer that has more than one operating system installed. Each operating system can be used at different times but not simultaneously. Reasons for multiboot can be software reasons. When we configure our computer to multiboot it is also important to install operating systems in the order they were released. Upgrade or Full Installation Media We also have a choice in the type of operating system installation media. We can purchase an upgrade version of the operating system or a full version. Upgrade versions are typically cheaper than the full versions. Upgrade versions are for users that already have a previous copy of Windows installed on their computer, types of windows operating system who want to install the newer version on the same computer. Full versions are sold to those who do not yet have a copy of Windows, or who have versions that do not qualify for an upgrade version. Full versions of the operating system can only be installed using a clean or new installation. With upgrade versions we might be able to choose between either an in place upgrade or a clean installation, or we might be forced to perform a clean installation. Also, in this case we would typically qualify for the upgrade pricing, although we have to do a full installation. If we want to move from Vista to Windows 7, we can use the upgrade pricing. In general, a one step or two step upgrade in versions typically allows us to qualify for the upgrade pricing. In other words, upgrade versions are typically available for purchase if we have up to two versions lower than the new version. A three step upgrade to a different version forces us to purchase the full version of the new operating system. Also, a one step upgrade allows us to choose between either an In-place or a full installation. We can only perform an in-place upgrade if types of windows operating system are types of windows operating system only one version up. Backup Before doing the upgrade on the installation we should do a full system backup of our current system, especially if we are doing an in place upgrade. The backup gives us a way to recover and go back to our original installation if something goes wrong with the new installation. Also, if we are doing a clean install, we can use the backup to restore user data to the new installation. Remember To do a clean install we can either wipe out an existing operating system on existing partition and then install Windows, or we can install Windows on a brand-new partition. The clean installation requires migrating our data, as well as reinstalling all of our applications. In-place upgrade will maintain all of our users, applications, settings and files. In migration we want to migrate user files and settings from the source to the destination installation. Migration can be performed either using the Side-by-side or Wipe and Load method. Dualboot or multiboot refers to a computer that has more than one operating system installed. It is important to install the operating systems in the order they were released. Before installing Windows we should check if the hardware meets Windows requirements. Things to also consider is file system.
