- Running Multiple Operating Systems
| Layers Accessing computer resources is divided into layers. The user represents one layer atone end of the system. Your computers hardware represents the layer at the opposite end of the system. In order to use your hardware to do anything with the computer, you need software. Software forms the layers in between the user and the hardware and is divided up into application software and the operating system. The operating system must be able to manage resources from both the applications and hardware layers. In the computer layer system the user interacts directly with software applications. The applications interact with both the user and the operating system. The operating system interacts with the applications and controls the hardware. Each layer is isolated and only interacts directly with the layer below or above it. If you make changes to anyone layer, they only directly affect the layer next to it. For example, if you install anew hardware device you do not need to change anything about the user or applications. However, you do need to make changes to the operating system. You need to install the device drivers that the operating system will use to control the new device. If you install anew software application you do not need to make any changes to your hardware. But you do need to make sure the application is supported by the operating system and the user will need to learn how to use the new application. If you change the operating system you need to make sure that both your applications and your hardware will work with the new operating system. Running Multiple Operating Systems It is possible to install more than one operating system on a computer. You can do this by partitioning your hard disks) and installing different operating systems on different partitions. This can be very useful, because you may want to use different operating systems to perform different tasks. For example, you may have specialized applications that will only work with one operating system, making them incompatible with the rest of your software. When you turn your computer on, you are given a choice of which operating system to use. You can only run one operating system at a time. Figure 2.2 (right) shows the system of layers when multiple operating systems are installed on the same computer. USER APPLICATIONS OPERATING SYSTEM HARDWARE Download 2.34 Mb.
