Answer to Question #241520 in Software Engineering for Garima

Question

  “Operating systems keep evolving over the period of time.” Elaborate the statement and also discuss various types of operating system. [10]

Answer 1

This is a correct statement because operating systems that do not change over time become a dead product. Indeed, in 1990s or early 2000s nobody could imagine that since 2020, Windows will be able to exchange cached data with Android smartphones (Samsung).

Here we approach the different types of operating systems:

• Batch (interacts with a machine indirectly)
• Time-sharing (share tasks between CPUs in time)
• Network (working via a network)
• Distributed (over different machines)
