History and evolution of Operating System
What is an operating system?
An operating system
(OS) is a software program that controls the hardware of a computer and manages
the resources of the system, such as the CPU, memory, and storage. It also
provides a platform for running other software applications.
There are many
different types of operating systems, including those for personal computers,
servers, and mobile devices. Some common examples of operating systems include
Windows, macOS, Linux, iOS, and Android.
History of Operating Systems:
The history of
operating systems dates back to the 1950s when the first computers were
developed. At that time, computers were very expensive and were primarily used
by governments and large corporations for scientific and military purposes.
These early computers were large and complex and required specialized
personnel to operate and maintain them.
The first operating
systems were developed to make it easier to use and manage these early
computers. An operating system is a software program that controls the hardware
of a computer and manages the resources of the system, such as the CPU, memory,
and storage. It also provides a platform for running other software
applications.
Over the years,
operating systems have evolved to become more user-friendly and powerful, with new features and capabilities added to meet users' changing needs. Today, many different operating systems are in use, including
Windows, macOS, Linux, and mobile operating systems such as iOS and Android.
List of different operating systems
Here are some examples
of operating systems that have been developed from the 1950s to the present
day:
1950s:
Early computers are
developed, and the first operating systems are created to make it easier to use
and manage these complex machines. Examples include the UNIVAC IOS and the IBM
701 OS.
UNIVAC IOS
(Input/Output System) and IBM 701 OS (Operating System) were early operating
systems that were developed in the 1950s for use on mainframe computers. Both
systems were designed to make it easier to use and manage the large and complex
computers of the time.
UNIVAC IOS
It was developed by the
UNIVAC division of Sperry Rand Corporation for use on their UNIVAC I computer.
It was one of the first operating systems to use the concept of a "job
stream", which allowed multiple programs to be run on the same computer in
sequence without the need for human intervention.
IBM 701 OS
It was developed by IBM
for use on their 701 computer. It was one of the first operating systems to use
the concept of virtual memory, which allowed the computer to use more memory
than it had physically available by temporarily transferring data to and from a
disk. IBM 701 OS also introduced the concept of a "master control
program", which was responsible for managing the resources of the system
and allocating them to different tasks.
Both UNIVAC IOS and IBM
701 OS were important early operating systems that laid the foundations for
many of the concepts and features that are common in modern operating systems.
Time-sharing operating
systems are developed, which allow multiple users to access a single computer
simultaneously. Examples include the CTSS and the MULTICS.
CTSS (Compatible Time-Sharing System) and MULTICS (Multiplexed
Information and Computing Service) were early time-sharing operating systems
that were developed in the 1960s. Time-sharing operating systems allow multiple
users to access a single computer simultaneously, each running their own
programs on the system. This was a significant advance over earlier operating
systems, which required the computer to be shut down and restarted between each
job.
CTSS
It was developed by MIT (Massachusetts Institute of Technology) for use
on their IBM 7094 mainframe computer. It was one of the first operating systems
to use the concept of a "virtual machine", which allowed each user to
have their own virtual computer with its own memory and resources. CTSS was also
one of the first operating systems to include support for interactive
programming, which allowed users to enter and run programs directly from the
command line.
MULTICS
It was developed by a consortium of companies, including MIT and Bell
Labs, for use on mainframe computers. It was a highly advanced operating system
for its time, and was one of the first to include support for multi-user,
multi-tasking, and virtual memory. MULTICS was also one of the first operating
systems to use the concept of a "hierarchical file system", which
allowed files to be organized in a tree-like structure with directories and
sub-directories.
Both CTSS and MULTICS were important early operating systems that laid
the foundations for many of the features and concepts that are common in modern
operating systems.
1970s:
Personal computers are
developed, and operating systems such as UNIX and DOS are created for these
machines.
UNIX and DOS (Disk
Operating System) are two operating systems that were developed in the 1970s.
Both systems are still in use today, although they have evolved significantly
since their original release.
UNIX
It is a multi-user,
multi-tasking operating system that was developed at Bell Labs in the 1970s. It
is known for its portability, scalability, and reliability, and has been widely
used on a variety of platforms, including mainframes, servers, and personal
computers. UNIX has a rich history and has inspired the development of many
other operating systems, including Linux and macOS.
DOS
It is a single-user,
single-tasking operating system that was developed by Microsoft in the 1980s.
It was originally designed for use on personal computers, and was widely used
on IBM-compatible PCs during the 1980s and 1990s. DOS was known for its simple
command-line interface, which allowed users to enter commands to perform tasks
on the computer. DOS has since been replaced by more modern operating systems,
such as Windows, but it is still used in some specialized applications.
UNIX and DOS are two
important operating systems that have had a significant impact on the
development of computing.
