May 23, 2021 That's what Linux should learn
When students read this section, I
believe you have been basically familiar with Mr. Liu Wei's writing characteristics (but not lecture characteristics) - can use a word to clear things,
I will never make a paragraph.
The benefits are obvious, first of all, the article is no longer lengthy, with a lot of pictures that look very interesting, and second, it allows you to find the most important knowledge and dry goods at a glance, so next
Linux
history and development, please pay attention to each point in time.
Back
20
1970s,
UNIX
were open source and free.
70
But
1979
AT&T
announced plans to commercialize
UNIX
systems, the open source software industry was transformed into a copyrighted software industry, with source code treated as a trade secret and patented products, and people were no longer free to enjoy the technology.
So in
1984
Richard Stallman
launched the GNU Open Source Program
GNU
license agreement for
GPL
authoring environment.
1987
GNU
program achieved a major breakthrough ,
gcc
compiler release, which allowed programmers to write their own open source software based on the compiler. T
hen, in
1991
Linus Torvalds
a student at the University of Helsinki in Finland, wrote
Linux
10
T
he system was quickly supported by the GNU program and a large number of hacker programmers
GNU
features based on the
GNU GPL
license agreement.
The
Linux
system then entered a boom phase of development.
1994
Bob Young
building on the
Linux
1
integrated a wide range of source code and program software, released Red Hat and began selling technical services, further
Linux
systems.
1998
as
GNU
source program
Linux
systems continue to heat up, IT
Intel
IT
IBM
and Intel, have been pushing hard for open source software. B
y
2017
the
Linux
4.13
and there were hundreds of
Linux
system versions, but they still used the
Linux
system
Linus Torvalds
RedHat
also become a leader in the open source
Linux
systems.
During lectures, I often ask my classmates a question: "Why learn
Linux
"
A lot of students say, "Because
Linux
source, they have to learn" to make me happy. I
n fact, this idea is completely wrong! O
pen source operating systems say less
100
open source software at least 100,000, why not learn one by one? So the open source features mentioned above are only part of the advantage and are not enough to be a reason to work hard.
For users, the open source spirit is only the icing on the cake, so the correct learning motivation should come from:
Linux
system is a
UNIX
interface, and
UNIX
can better meet the needs of the job.
Most readers should start with
Windows
to understand computers and networks, so there's definitely the idea that
Windows
works well, and it's good enough for everyday work." O
bjectively speaking,
Windows
systems are really good, but they're not satisfactory in terms of security, high availability, and high performance. Y
ou should have seen the picture below.
Readers must now be able to guess why
Linux systems should be used on web servers that require long-term, stable operation, cluster systems that
Linux
work together.
The following image also shows

systems.
Linux
advantage readers can first understand without deep study, learning and then slowly feel.
