3. Summarize the history of System
Administration.
During the Dawn of Computing: System Operators in 1952–1960, the IBM 701 was the first commercial
computer and it was finished in 1952. All computers existed before the 701 as one-offs. The IBM 704, a
new and improved version of the 701, was introduced in 1954. It had three index registers and 4,096
words of magnetic core memory. It performed floating-point arithmetic and used 36-bit words (as opposed
to the 701's 18-bit words).Every second, 40,000 instructions were carried out.
John McCarthy started considering time sharing in the middle of the 1950s. Corbato was serious when he
proposed allowing "each computer user to act as if he were the only person in control of a computer
in 1964. Bell Labs and General Electric started a project to create an ambitious Multiplexed Information
(Multics) Time Sharing System as well as Computing Service. Multics was over budget and far behind
schedule five years later after schedule then Bell Labs walked away from the undertaking.
4. After that event, UNIX was born in the year 1961- 1969 and that is when Bell abandoned
Multics project and left several researchers nothing to do.
In year 1974-1960, the quantity of UNIX installations tripled over the subsequent six
months. The response was overwhelmingly positive when the paper was published in the
Communications of the ACM issue from July 1974. Shared UNIX systems were seen by
research labs and universities as a potential answer to their expanding demand for
computing resources.
And then System Administrators are becoming more popular. The Universities were
early leaders in the development of organized system administration groups because UNIX
was popular at universities, and those environments included a large number of students
eager to learn the latest technology.
Evi Nemeth became known as the "mother of system administration" after she
recruited undergraduates to work as system administrators to support the University of
Colorado's Engineering College. Her connections with people at Berkeley, the University of
Utah, and SUNY Buffalo resulted in the formation of a system administration community
that shared tips and tools.
5. Requests for documentation and training became more common. So, Tim O'Reilly
and his team began to publish UNIX documentation that was based on hands-on
experience and written in a straightforward manner.
Linux is born after UNIX is nearly brought to an end and this occurred between the
year 1991 and 1995. After that, the Windows World in year 1996 to 1999 and
without a doubt, the Microsoft platform has advanced significantly, and for some
businesses, it represents the best choice. Many system administrators for UNIX and
Linux started learning Windows because they were afraid they would lose their jobs if
they didn't.
Linux and UNIX both succeed in year 2000 until now. So, It became clear that many
organizations with successful technology strategies used UNIX or Linux alongside
Windows rather than just one or the other. The conflict had ended.
6. What is meant by “ System administration is like
keeping the trains on time; no one notices
except when they’re late.”
For us, the quotation “System administration is like
keeping the trains on time; no one notices except when
they’re late.” means that system administration is a very
important because they are the ones who operates,
performs and they are responsible for maintaining and
keeping the system working well. But some people didn’t
notice the importance of system administration except
when they are late.
