When using Javascript to implement interaction between the client and the server, you sometimes need to judge the operating system to achieve compatibility under different operating systems. For example, we have a website, in Windows XP, the browsing effect is good, but in Ubuntu, due to many different features, it may cause slight differences in browsing, and ev

It is often possible to use an operating system (such as Windows and Linux) because of the need for work or learning. The file systems supported by Windwos may be familiar, and the file systems supported by the Linux operating system may be unfamiliar. It is often necessary to copy files from Windows to the Linux syste

File systems are typically implemented in a hierarchical structure: file management, directory management, and Disk Management file control blocks (BLOCK,FCB) are the only data structures that the operating system establishes for each file and contains all the file attributes. The FCB is usually pooled and organized together to form a file directory with two directory entries, each describing subdirectories

I would like to recommend a book on embedded entry: Embedded System Design (Chongqing University Press, author Peng ). I have also made some good looks recently. I have summarized some of the embedded knowledge we learned before, as well as the operating system and composition principles, this is a summary of the knowledge learned in this book and a review of the previous knowledge.
I personally think that the learning of embedded
For windows systems, the version is not determined here. If necessary, you can continue to judge the version after determining windows. The java version needs to be considered. The version is different and the results are different.

A thread is also called a mini process. Threads are lighter and easier to create than processes. It is easier to switch. If a large number of intensive computing and IO operations exist. Multiple Threads are allowed to overlap these activities.
