Share this post:. Linux 5. Now, one year after this quite controversial feature was made available, Collabora and others keep building on top of it to make it more and more useful for system developers and end users. Therefore, this seems like a good time as any to take a look on why this was merged, and how to put it to work.
The Linux Kernel as a Case Study on Rapid Development for Complex Software
Advantages And Disadvantages Of Linux Kernels | locu-teatrale.info
A big turbocompressor in an oil extraction plant is controlled by a year-old Digital Control System DCS , which provides all the supervision functions, plus the logging of significant events and data onto a printer. The system has been running satisfactorily for years, but now the management would like to integrate the machine into the global plant SCADA system, where data from various machines are gathered and processed in order to provide integrated management of the entire plant. The PLC-based architecture of the existing DCS is hardly expandable and doesn't allow, from either the hardware or software point of view, for the addition of the data transmission functions which would be necessary for the project. A redesign of the DCS system to add the required functionalities was considered an excessively high-impact solution for the purpose. The latter will periodically issue data queries to receive the data values from the gateway. For this part of the connection, the standard protocol Modbus RTU was selected because of its simplicity and because it was already widely used throughout the plant.
The role of trust in OSS communities - Case Linux Kernel community
Monolithic A monolithic kernel is one single program that contains all of the code necessary to perform every kernel related task. In the monolithic kernel, some advantages hinge on these points:. Fragmentation occurs after space reclaimed after files are deleted and is used to store parts to a larger file. The result is that files do not exist in disk locations. Most operating systems has an utility to defragment a file system.
It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. How does the mapping of the stack, heap, data segments all going to happen? I am not able to find any example for my understanding. Text book only mentions separately for each mapping but not a practical approach.
