1.0 Introduction of Instruction
You will use Human Language to tell the way to go to KFC, something as follows -
1. Go straight.
2. Drive half kilometer.
3. Take left.
4. Drive around one kilometer.
5. Search for KFC at your right side.
The above sequence of instructions is actually a Human Program written in English language,
which instructs on how to reach KFC from a given starting point. this same sequence could have been given in Spanish, Hindi, Arabic, or any other human language, provided the person seeking directions knows any of thsese language.
Introduction of Programs
A computer program is a sequence of instruction written using a Computer Programming Language to perform a specified task by the computer.
1. Sequence of instructions
2. Computer Programming Language
Python Programming Language print "Hello, World!"
- The above computer program instructs the computer to print "Hello, World!" on the computer screen.
- A computer program is also called a computer software, which can range from two lines to millions of lines of instruction.
- Computer program instructions are also called program source code and computer programming is also called program coding.
- A computer without a computer program is just a dump box; it is programs that make computers active.
Uses
Almost every field, household, agriculture, medical, entertainment, defense, communication, etc
- MS Word, MS Excel, adobe Photoshop,
Introduction of Programming Language
The act of writing computer programs is called computer programming. As we mentioned earlier, there are hundreds of programming languages, which can be used to write computer program as:
- Java
- C
- C++
- Python
- PHP
- Perl
- Ruby
Introduction of Programmer
Someone who can write computer programs or in other words, someone who can do computer programming is called a Computer Programmer,
Based on computer programming language expertise, we can name a computer programmers
as follows-
- C Programmer
- C++ Programmer
- Java Programmer
- Python Programmer
- PHP Programmer
- Perl Programmer
- Ruby Programmer
Introduction of Algorithms
From Programming point of view, an algorithm is a step-by-step procedure to resolve any problem.
An algorithm is an effective method expressed as a finite set of well-defined instructions.
- Get a list of numbers L1, L2, L3.......Ln
- Assume L1 is the largest , Largest = L1
- Take next number Li from the list and do the following
- If Largest is less than Li
- Largest = Li
- If Li is last number from the list then
- Print value stored in Largest and come out
- Else repeat same process starting from step 3

Introduction of Pseudocode.
public partial clas Default3 : System.Web.UI.Page
{
SqlConnection con = new
SqlConnection(WebConfigurationManager.ConnectionStrins["civilRegDB"].ConnectionString)
;
SqlCommand cmd = new SqlCommand();
SqlDataReader dr;
int total;

{
con.Open();
cmd.Connection = con;
}

Computer Language
Computer की भी अपनी भाषा होती है जिसे Computer समझता है। गणनाये करता है और परिणाम देता है. Programming Language Computer की भाषा है जिसे Computer के विद्वानों ने Computer पर एप्लिकेशनों को विकसित करने के लिए Design किया है. पारंपरिक भाषा कि तरह ही प्रोग्रामिंग भाषाओं के अपने व्याकरण होते इसमें भी वर्ण, शब्द, वाक्य इत्यादि होते हैं.
