CCNA Chapter 1: 7 layers  OSI  model :

  Collection of pre-defined Function Necessary For the operation of a program.                                 Names of the header files finish with .H Header Files 1-       String. H –Contains String Manipulation Function. 2-       Alloc. H – Includes memory allocation Function. 3-       Time .H – Consists of time related Function 4-       Conio. H – Console input & output Function 5-        Ctype  H – Include type conversion function 6-       Stdlib. H – Standard Library function 7-       Graphics .H – Has Graphics Function 8-       Dos .H – Define date , time & Sound Related Function 9-       Process. H – Contains System Related Function Note - Several of the header files provided with the OS end with . Inc (Include file) Additional header files Can be Found in Either /User/Include or Usr/Include/Sys directory.  The Main ( ) is surrounded by the Curly bracket has two parts. Declaratory part – Declaring Variables Achievable part

The Structure of ‘C’ Program “C Language also has the Standard Structure “                 < Include Header Files >                 [Global Declarations]                 Main ( )                      {                          < Local Declarations>;                            < Statements>;                      }              //    Execution Start from the main ( )  1-Printing a Text Message # Include <Stdio.h>  Main ( )                   {                                   Printf (“Welcome to C Programming”); }              

Compiler & Interpreter                  Compiler -  o    Transform Source Code into Machine Code. o    Perform Checks the whole Program  o    C-Language is Compiler based program.                 Interpreter – o    Performs checks Line by Line. o    Slower than a Compiler. o    Similar to Compiler. Source.C – |Compiler|--- – Source. Obj – |Linker-|---Source.Exe

The Programming Languages                 Artificial Languages used to Control the Behavior & Properties of a Computer.                 Syntax - that refers to the Spelling & Grammar.                 Uses - Application Development (Payroll, Banking and Reservation) etc.                 Utilities -Predefined API                 Servers -Share data to Other Computers                 System Programs –OS               T ypes – o      Low Level or machine Language. o    Assembly Language o    High Level Language o    Procedural or Structural Language. o    Low Level Language - Contains Numerical data o    Easily understood by Computers o    Difficult to understand by Humans o    Assembly Language - o    Similar to the Machine Language o    Contains Characters. o    High Level Language – o    Used to develop Complex Applications o    Closer to the Human Language, But It is not dependent on any particular Computers. o    Procedura

Inspire With C Programming UNIX OS : Widely Used in both Servers & Work Stations. Direct-X:  Application Program Interface (API) o    Creating & Managing Graphics etc. Written in C, visual C/C++, or Java.            SDL-Simple direct media Layer/Library ·          Supports 20 graphics, Open GL, Sound, Events, Threads, Networking ·          Written in C, also Ada, C#, Eiffel, Erlang, Euphoria, Java, and Lisp etc.  Frame Works -       Apple’s Mac Applications.           Symantec’s think class Libraries.
