Fundamental of internet and www concepts
Web
When large number of computer are interconnected with each other then make a web.
The web is the part of internet consisting of various computer exchanging web pages
World Wide Web (WWW)
The part of internet that stores information in multimedia from that is sound, photos, and video as well as text and make the exchange of information easily.
The number of computer connected to the internet world wide is said to to have topped 82 million in 1996 and is predict to reach 300 million by 2003
How does the www work?
1)      Web information is stored in documents called webpages.
2)      Web pages are files stored on computers called web servers.
3)      Computer reading the web pages are called web clients.
4)      Web clients view the pages with a program called a web browser.
5)      Popular browser are internet explorer, Firefox , Google chrome, etc.
Uniform resource locator (URL).
URL is stand for uniform resource locator. It is also called web site address. URL maybe defined as unique way to access the different services on the internet.
The URL is string and character that point to a specific piece of information anywhere on the web.
A URL consists of
1)      The web protocol
2)      the name of the web server
3)      the directory or folder on that server and
4)      the file within that directory
Example http://www.ptv.net.pk
Web Server
It is the specific type of the software and hardware system that provide services to its client.
A web server is the program that waits for browser to request a web page
Web page (Hypertext Documents)
A web page is the documents on Web consisting of an HTML file. The home page, or welcome page, is the main page or first screen you see when you access a website, website and home page tend to be used interchangeably, although a site may have many pages.

Website (locations of hyperlinked document)
The places you visit on the web are called websites, and the estimated no of such sites through  out the worlds ranges above 1,250,000. A website is the internet location of a computer or server on which a hyper linked document is stored.
Any person in the world who know the web site address can access it.
For example ptv.net.pk, ptcl.com.pk and vu.edu.pk etc.

programming

                         

C++ Tutorial

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language and originally named C with Classes but later it was renamed C++ in 1983. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.

Execute C++ Online

Try following example using Try it option available at the top right corner of the below sample code 
#include <iostream>
using namespace std;

int main()
{
   cout << "Hello World";
   return 0;
}
C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.

         Object-Oriented Programming





C++ fully supports object-oriented programming, including the four pillars of object-oriented development:


    

  • 
Encapsulation
    

    • 

  • 
Data hiding
    

    • 

  • 
Inheritance
    

    • 

  • 
Polymorphism
    

    • 

  • 
        Standard Libraries
    

    • 

  • 

    
Standard C++ consists of three important parts:
    

      

    • 
The core language giving all the building blocks including variables, data types and literals, etc.
      

      • 

    • 
The C++ Standard Library giving a rich set of functions manipulating files, strings, etc.
      

      • 

    • 
The Standard Template Library (STL) giving a rich set of methods manipulating data structures, etc.

                  IN THIS BLOG, WE WILL LEARNT ABOUT INTRODUCTION OF COMPUTER HARDWARE&SOFTWARE AND ALSO LEARN ITS COMPONENT.


 DEFINITION  OF COMPUTER: 
                     The computer is an electronics device,operating control of instruction  stored in its own memory , that can accept data,process data according to specified rule,produce result and store the data for future use.
     
THE COMPONENTS OF COMPUTER:
     The computer contain many electronic and mechanical component known as  hardware. In components include input & output device communication device,mass storage device and unit system device etc..
     common computer parts are following:
•Hardware

  • –Mechanical devices in the computer
  • –Anything that can be touched

•Software

–Tell the computer what to do–Also called a program–Thousands of programs exist

•Data

       –Pieces of information–Computer organize and present data

•Users
       –People operating the computer–Most important part–Tell the computer what to do
•Steps followed to process data
•Input
•Processing
•Output 
•Storage  
•Hardware categorized into four types:
•Processing devices
•Memory devices
Random Access Memory (RAM)
Read Only Memory (ROM)
•Input and output devices 
–Input devices accept data
•Keyboard, mouse
–Output devices deliver data
•Monitor, printer, speaker
–Some devices are input and output
•Touch screens
•Storage devices
–Hold data and programs permanently
–Different from RAM
–Magnetic storage
•Floppy and hard drive
•Uses a magnet to access data
–Optical storage
•CD and DVD drives
•Uses a laser to access data
•Two types
–System software
–Application software
•System software
–Most important software 
–Operating system
•Windows XP
–Network operating system (OS)
