operating system concepts 9th

With the development of IC card from a simple synchronous card to an asynchronous card, from a simple EPROM card to the internal microprocessor-based smart card (also known as CPU card), the requirements of the IC card is more and more high. The management of the card itself is more and more complex, so there is an urgent need to have a tool to solve this contradiction, and the emergence of the internal microprocessor-enabled smart card, so that the realization of this tool has become a reality.

a slightly complex example. A project consists of three C language source files. c. B. c and hello. h, where. c and B. c contains hello. h. The final output executable file is hello. Table 2 contains the content of this Makefile. To learn more about the use of Make and the compilation of Makefile, you can refer to its reference document at http://www.gnu.org/manual/make-3.79.1/html_chapter/make_toc.html. If the source program is more complex, such as adding more source files and attaching a cer

1st important events: Do not rush to access the network After Windows is installed, do not immediately connect the server to the network, because the server is not installed with various patches, there are various vulnerabilities, it is very easy to be infected with viruses and intrusion. In this case, we need to add the shock wave and shock wave patches, restart them, and then connect them to the Internet. 2nd important events: patch the system and i
