•  Entertainment: Till now television was the only way of home entertainment. The trend has changed tremendously.
                Nowadays there’s a parallel entertainment industry that is producing entertainment programs for online mediums.
                There are series and movies that are launched online only.
            2.  Define any two ICT tools.
          Ans.  Following are the tools of ICT:
              •  Computers: The most appropriate ICT tool is a computer. It’s an electronic device that accepts an input, processes it
                and returns a desired output. More than a luxury it has become a necessity. Its need is felt by people in all walks of life.
              •  Internet and Emails: New ways of information and communication. The Internet is an unending medium where
                information at all possible topics is available. Electronic mails (Emails) have added speed to communication. A message
                can be conveyed instantly and you have the privilege to be connected all the times.
            3.  What are the four basic operations of computers?
          Ans.  Computer performs four basic operations:
              •  Input (Raw Data): It is the collection of raw facts or figures in the form of text, numbers, graphs, etc. Also called raw
                data or unprocessed data. Provided to the computer using Input devices like keyboard, mouse, scanner etc.
              •  Process: It is the methods used to convert raw data into meaningful information. The Central Processing Unit (CPU) of
                the computer is responsible for processing of data.
              •  Output (Information): It is the processed data which has been manipulated and arranged in the form the user wants. It is
                also called meaningful data or Information. Given to the user through output devices like monitor, Printer, Plotter, Speaker etc.
              •  Storage: It is storing either raw data or processed information. Stored either using secondary storage devices like Flash
                drive, Hard disk, Compact Disk or online storage medium like Google cloud, etc.

            4.  Explain the different parts of the CPU.
          Ans.  CPU is basically divided into three parts:
              •  ALU stands for Arithmetic Logic Unit. It is responsible for all mathematical and logical calculations.
              •  CU stands for Control Unit. It controls the flow of information in the system. The control unit is responsible for the flow of
                data from input devices to the process unit and then to the output devices. It works like a traffic policeman who controls
                the traffic on the road.
              •  MU stands for Memory Unit. It is a storage unit that holds the processed or unprocessed data.

            5.  Define OS. Give examples of operating systems.
          Ans.  An operating system is system  software which acts as an interface between the user and the computer. It is  an
              important component of a computer system which controls all other components of the computer system. It helps us
              to communicate with the computer without knowing its language. Without an Operating System the computer is of no
              use. Some of the commonly used Operating systems are Windows, DOS, UNIX, etc.
            6.  Differentiate between UNIX and DOS.
          Ans.                    UNIX                                          DOS
                It  is one  of  the  oldest,  reliable and  powerful  After  Unix,  DOS is one  of  the  most commonly used
                Operating  systems developed at  AT&T’s Bell  operating System written originally by Tim Patterson.
                Laboratories in the early 1970’s.
                It supports multiuser and multitasking.    It is a single-user operating system.

            7.  What is a Taskbar? What does it contain?
          Ans.  It is the thin strip present at the bottom of the screen. By default it is always visible at the bottom but we can choose
              the auto hide option in the taskbar settings which will disappear the task bar. But it will reappear only when the mouse
              cursor moves down to that area. It contains the following important components: Start Menu, Quick Launch Program
              icons, Notifications Area, System Clock, Show desktop button.

            8.  Mention features of Mobile Operating system.
          Ans.  Some of the important features are:
              •  It has a Graphical user interface with menus and buttons supporting different types of apps.
