Need of Operating System

There are various needs of operating system:

  1. Managing Input-Output Unit
  2. The Operating system as a platform for application programs
  3. Multitasking
  4. Consistent user interface
  1. Managing Input-Output Unit: - With the help of the operating system, the computer can handle its resources like keyboard, monitor, printer, memory, etc. The resource management is needed for efficient utilization of the resources. The operating system is responsible for managing several input-output resources and assigns these resources to the user based needs.
  2. The Operating System as a Platform for Application Programs: - The operating system is responsible to run the application program. With the help of the application programs, we can perform specific tasks efficiently. The application programs are just like the interface between the computer and the user. The application programs are structured in such a way so that multiple applications can be managed and executed on the computer.
  3. Multitasking: - With the help of the operating system, memory is managed. The OS enables various programs to run in their own space and even interact via shared memory with each other. Multitasking offers an excellent experience to the users that they are able to perform multiple tasks on a computer simultaneously.
  4. Consistent User Interface: - The operating system offers a simple user-interface (UI) to the users so that there is no need to learn various user-interface (UI) every time, and the users can focus on the content. The operating system also offers templates and UI components so that the Computer’s working becomes easy and simple to the user.

Solaris Operating System

In 1992, the Solaris operating system was developed. The Solaris operating system was established by Sun Microsystems and it is a Unix based operating system. Historically, Sun has dominated the broad market for UNIX workstations. When the internet expanded in the early 1990s, the Sun’s SPARC/Solaris systems have been the most commonly deployed web site severs. Sun emphasizes the availability of the system (that means it rarely crashes), its wide range of features, and internet-oriented architecture.

Features of the Solaris Operating System

There are various features of the Solaris operating system:

  1. Security
  2. Scalability
  3. Availability
  4. Solaris is built for network computing
  1. Security: - The Solaris operating system comprises of various security features, and it supports Kerberos, IPsec, Smart cards, and AMI.
  2. Scalability: - Another feature of the Solaris operating system is scalability. In the Solaris operating system, if we want to use the large processor, then due to this, our application will not only run but will run faster.
  3. Availability: - In the Solaris operating system, due to its special features addition, the problem fixing became easy without restarting a system.
  4. Solaris is Built for Network Computing: - The Solaris operating system is mainly developed for network computing.

Extensions of the Solaris Operating System

There are three extensions of the Solaris Operating System:

  1. The Internet Service Provider (ISP) Server.
  2. The Easy Access Server.
  3. The Enterprise Server
