HOW OPERATING SYSTEM WORKS?

  • * It manages the hardware and software resources of the system. In a desktop computer, these resources include such things as the processor, memory, disk space and more.
  • * Computer's operating system coordinates the demands that the computer's software makes on its hardware, especially the central processing unit (CPU). It's the operating system's job to make sure that each application gets its fair share of your computer's finite resources in the most efficient way possible.
  • * The operating system provides a consistent set of rules for applications to use in order to be able to interface with your computer's hardware.

Question 2


ANDROID
 
WINDOWS 8
GOOGLE PLAY
DISTRIBUTOR
MICROSOFT CORP
ORIGINALITY OF GOOGLE PLAY APPLICATIONS WAS EASILY TO BE COPIED NOWADAYS
THE ORIGINALITY OF OPERATING SYSTEM
ORIGINALITY OF WINDOWS 8 OF MICROSOFT STILL CAN BE MAINTAINED
NEED TO DOWNDLOAD APPLICATIONS TO READ OR VIEW FILES/PDF.
FILE OR DOC. VIEWING
ALREADY AVAILABLE WITH MICROSOFT TOOLS OFFICE (e.g MICROSOFT WORDS , POWERPOINT , EXCEL)
ONCE UPGRADED , THE PREVIOUS INSTALLENT TERMINATED
VERSION UPGRADES
EVENTHOUGH IT IS UPGRADED , THE PREVIOUS APPLICATION IS STILL THERE
 
OFTEN
VERSION UPDATES APP
SELDOM
MORE THAN 700K APPS
APPS AVAILABLE
AROUND 100K APPS
MORE THAN WINDOWS USER
USERS
LESS THAN ANDROID USER
 
 
THE SPEED , STABILITY AND FEATURES OF ANDROID CAN VARY FROM ONE TO ANOTHER , BUT WINDOWS PHONE IS FRIENDLY AND FAST.
 


*CONCLUSION WE MADE , ANDROID WAS MORE TO SOCIAL WHILE WINDOWS MORE TO EDUCATIONAL AND BUSSINESS WORKING.
