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.  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.  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.  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.  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.  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.  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.  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.  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.  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…..
