Answer 1

HISTORY :

Windows 10 : Windows 10 is an operating system developed by Microsoft.Microsoft described Windows 10 as an "operating system as a service" that would receive ongoing updates to its features and functionality,augmented with the ability for enterprise environments ti receive non-critical updates at a slower pace or use long-term support milestones that will only receive critical updates such as security patches over their five years lifespan of mainstream support.Terry ,executive vice president of Microsoft's Windows and Devices Group said that the goal of this was to reduce fragmentation across the Windows platform

UNIX: The history of Unix dates back to the mid-1960s when the Massachusetts Institute of Technology,AT&T Bell Labs and General Electric were jointly sharing operating systems called Multics for the GE-645 mainframe Multics introduces many innovations but had many problems.

Bell Labs,frustrated by the size and complexity of Multics but not the aims,slowly pulled out of the project.Their last researchers to leave Multics,en Thompson,Dennis Ritchie,Doug Mcllroy and Joe Ossanna among others decided to redo the work on a much smaller scale.In 1979 Dennis Ritchie their vision of Unix

Android: The version history of the android mobile operating system began with the public release of the android beta on November 5,2007.The first commercial version,Android 1.0 was released on September 23.2008.Android is continually developed by Google and the open Handset Alliance to its base operating system since the initial release.

MEMORY MANAGEMENT :

WINDOWS 10: Each process on 32-bit Microsoft Windows has its own virtual address space that enables addressing up to 4 gigabytes f memory.Each process on 64-bit Windows has a virtual address space of 8 terabyte.all threads of a process can access its virtual address space.However,threads cannot access memory that belongs to another process,which protects a process from being corrupted by another process

UNIX: UNIX memory management includes the following

        1.Single partition Allocation

        2.Multi Partition Allocation

       memory management strategies:

        1.Overlays

        2.Swapping

        3.External Fragmentation Problem

       4.Solution

       5.Virtual Memory

       6.Demand Paging

       7.Page Fault problem

        8.Page Replacement Algorithms

Android: The Android Runtime and Dalvik virtual machine use paging and memory mapping to manage memory..Android use the following for topics for memory management

          1.Garbage collection

           2.Share Memory

           3.Allocate and reclaim app memory

           4.Restrict app memory

           5.Switch apps

PROCESSOR MANAGEMENT :

Windows 10 : The Windows 10 processor power management algorithms iimplement OS-level functionality that allows the OS to efficiently use the available processing resources on a platform by balancing the user's expectations of performance and energy efficiency..

UNIX: 2.0 Process Management In UNIX.When we log on to a computer running UNIX a shell or GUI process is started to service our commands.The UNIX operating system keeps track of the users and their processes and prevents processes from interfering with one another..

ANDROID: A process on Android can be in one of five different states at any given time,from most important to least important.

         1.Foreground process

         2.Visible process

         3.Service process

         4.Background process

         5.Empty process
