Low Level Language (LLL)

                 A low level language is  a programming language that is  machine-dependent.
                 It is closer to  machine code.  A machine dependent  language  runs  only on  a
                 particular type of computer.

                 High Level Language (HLL)

                 High Level Language (HLL) is a programming language that enables a programmer
                 to write programs that are machine-independent.

                 It  is closer  to  human  readable  language.  The  main advantages  of  high  level
                 languages  over  low  level languages  is that  they  are  easier to read,  write  and
                 maintain.

                 Scratch is a high-level, block-based visual programming language.

                     STARTING SCRATCH

                 To start scratch, follow these steps:

                 Step 1  Double-click on the Scratch icon if there is a shortcut on the
                          desktop.
                          or,

                          Click  on the  Start button.  Scroll  and  find
                          letter S in the program list.                                                          2

                 Step 2  Click on Scratch 3.

                 Components of the Scratch Window

                 Let us learn about the components of the Scratch window:

                    Sprite: It is an object or actor that we see on the Scratch stage. The orange “cat”
                    is the default sprite.
