                  Identify the following symbols and write their names:




                  (a)                       (b)                         (c)                    (d)








                 Programming is a useful skill for creating things like websites and games. It is a good language for
                 beginners because its simple syntax makes learning easy.




                        COMPUTER LANGUAGES

                 Programming languages are used to communicate with computers through words or characters
                 that describe actions. Writing these instructions is called programming and the people who do it
                 are called programmers.

                             Low-Level Language                               High-Level Language

                     Language (1GL)      Language (2GL)     Language (3GL)      Language (4GL)     Language (5GL)



                 LOW-LEVEL LANGUAGE
                 A low-level language is machine-dependent and works directly with a computer’s hardware,
                 giving exact instructions for managing it.


                 First Generation Language
                 The  First Generation of programming  languages or machine  language,  uses  binary  digits  (0
                 and 1) that computers directly understand. It is machine-dependent and works only on specific

                 hardware.

                 Second Generation Language

                 The  Second Generation of programming  languages  or assembly  language,  uses  symbols  or
                 mnemonics (like MOV, ADD, SUB) instead of binary. It is machine-dependent but easier to read
                 and write.
