Presentation on generation of languages

  1. 1. Created by: Richa Pant BBA (I st year) Roll no: 35
  2. 2.  A Computer languages are the languages by which a user command a computer. Just like human languages computer’s also have certain languages which they can understand. There are four generations of computer language, first generation ,second generation, third generation and fourth generation. Computer languages are of two types :- 1: Low level language -:first & second generation 2:High level languages-:Third generation
  3. 3.  It is also known as binary or machine language. These binary languages are mostly based on 0&1. These languages are quite difficult to understand. To develop a program in first generation language is complicated task. They are machine dependent language. They are also known as low level language (lll). The programs written on binary language used to executed very fast.
  4. 4.  These languages are also belong to the category of low level language (lll). Second generation language were also known as assembly language. The binary digits o&1 were replaced by some special symbol known as Mnemonics eg:-sub = -, add=+,div=/,sav=save. This language is machine independent language.
  5. 5.  They are also known as high level language (h.l.l). In this the commands written are in simple English language. Third generation language were portable. As the commands written are in simple language so special software were develop which are known as Language processor. For example:-LOGO, PASCAL; COBOL,JAVA etc….
  6. 6.  As 3gl were based on certain syntax ,which a programmer has to follow during developing a progran which is known as procedural language. To overcome from this problem fourth generation language were evolved. These programs were written in non-procedural way For example SQL, LIPS, PROLOG etc……
  7. 7.  They are system software they are used to translate high level language into machine language and vice –versa. These language processor converts high level language into computer understandable binary language(0&1). These language processor are of 3 types;- Compiler Interpreter Assembler
  8. 8.  It is a special type of software that converts high level program into binary code. It transfer whole program into a single goal it means the whole program will be converted into equivalent binary language. Its speed of translation is quite high but the execution speed is low.
  9. 9.  It use to convert high level language program into equivalent binary code by translating whole program line by line. Interpreter has slow speed of translation than compiler. T he program execution time is interpreter is less than compiler.
  10. 10.  It is also a language processor it converts the assembly language programs into object code, They are required in low level languages which were machine dependent. Today these assemblers are used to collect all component of the program and send to the leader and linker.
  11. 11.  Modem :It is modulator and demodulator that is used to convert analog signal into digtal signal and vice versa. Amplifier/Repeaters: It is used to boost up the weak signals. Routers: It is like traffic police that is used to direct the data that are transfer through networks. Clint &servers: Clint are the computer that has more storage capacity and are more powerful than other computer and server are the computer that are serve by clints . T here are some other networking devices: Bridge Cables Hubs etc…..
