Information Security system design basics first week study summary

This week, I learned about the history of Linux with some famous developers.

Operating system began in the 1950s, when a project called "Multics", its technology was very innovative at the time, but its development process is not smooth, then a development group to participate in the project-Bell Labs to develop their own operating system--unix after exiting the project.

UNIX was initially released free of charge and therefore popular in universities, but later became commercialized, expensive, and rarely used. In October 1991, Linus Torvalds in contact with UNIX at the University of Helsinki, hoping to run a similar operating system on his computer. Soon he began his own development work, his first release of the version quickly attracted some hackers, their participation so that it quickly has a lot of attractive features. He often rewrites the kernel, making it easier for some programs to run on Linux, including the C compiler, all from the Free Software Fund GNU project.

In the 1992-1993, the Linux kernel was able to challenge all the essential features of UNIX, including TCP/IP networks, graphical interface systems (X window), and Linux also attracted many industry concerns. Some small companies developed and distributed Linux, and dozens of Linux user communities were established. In the 1994, Linux magazine also began to release.

Compared to Windows, Linux is free, the platform is more secure, mostly open source free software, users can modify the customization and redistribution, but some software quality and experience is deficient, but can be customized, more free-line, can learn.

Our learning path is as follows:
