programming language and its types

What is a language?

Language is the medium of communication to share ideas, opinion with each other. For an example, if we want to communicate with someone, we need a language it may be English, Hindi, Spanish or another language. But you need at least one language to communicate with someone (human/person).
What is a programming language?

To communicate with a person, you need a language. Same if you need to communicate with the computer, you need a programming language. Without any programming language you cannot communicate with the computer.
Thus, programming language is the medium of communication between you (a person) and a computer system. It is the set of some instructions written in a specific style (coding) to instruct the computer to do some specific task.
Types of computer programming languages

There are basically three types of computer programming languages, they are
1.     Low level programming languages
2.     High level programming languages
3.     Middle level programming languages             

 High level language


                                                                                        

Advantages of High-Level Languages



The main advantage of high-level languages over low-level languages is that they are easier to read, write, and maintain. Ultimately, programs written in a high-level language must be translated into machine language by a compiler or interpreter.
The first high-level programming languages were designed in the 1950s. Now there are dozens of different languages, including Ada, Algol, BASIC, COBOL, C, C++, FORTRAN, LISP, Pascal, and Prolog.

Low  level  language
  • ·        A low-level language is a programming language that deals with a computer's hardware components and constraints. It has no (or only a minute level of) abstraction in reference to a computer and works to manage a computer's operational semantics.
  • ·         A low-level language may also be referred to as a computer’s native language.
  • ·        Low-level languages are designed to operate and handle the entire hardware and Low-level instructions set architecture of a computer directly. languages are considered to be closer to computers.
  • ·        In other words, their prime function is to operate, manage and manipulate the computing hardware and components. Programs and applications written in a low-level language are directly executable on the computing hardware without any interpretation or translation.
  • ·        Machine language and assembly language are popular examples of low-level language.


     Middle  level  language
·    
  •      Medium-level language (MLL) is a computer programming language that interacts with the abstraction layer of a computer system. Medium-level language serves as the bridge between the raw hardware and programming layer of a computer system.
  • ·        Medium-level language is mainly an output of the programming source code written in a higher-level language. It is designed to improve the translated code before it is executed by the processor. The improvement process helps to adjust the source code in accordance with the computational framework of the target machine.
  • ·        The source code of the medium-level language is not directly executable by the CPU as it’s an intermediate step before being converted into machine code. However, after it's analyzed by the primary software program, the medium-level language is interpreted into machine code for execution.

INTRODUCTION OF DBMS

-
What is Database :- The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently. It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty etc. Using the database, you can easily retrieve, insert, and delete the information. DBMS (Database Management System):- Database management system is a software which is used to manage the database. For example: MySQL, Oracle, etc are a very popular commercial database which is used in different applications.DBMS provides an interface to perform various operations like database creation, storing data in it, updating data, creating a table in the database and a lot more.It provides protection and security to the database. In the case of multiple users, it also maintains data consistency. DBMS allows users the following tasks:- Data Definition: I

INTRODUCTION Digital computer concept:- 1. Digital computers are designed to store, process and communicate information in digital form. 2. Digital computer is any of a class of digital devices capable of solving problems by processing information in discrete form. 3. It is used for processing data represented by discrete, localized physica signals, as the presence or electic current. 4.The main three components of digital computer:- >input:- The user gives a set of input data through input devices. >Processing :- The input data is processed with the help of CPU by well defined and finite sequence of step. >Output : - Some data available from the processing step are output to the user. TYPE OF DIGITAL COMPUTER :- 1.Microcomputer/Desktop computer 2.Minicomputer 3.Mainframe computer 4.Supercomputers Microcomputer :- 1.Microcomputer is also called a personal computer or desktop computer. 2.It includes a microprocessor, memory, and

There are 195 countries in the  world, some are developed countries, some are undeveloped , and some are underdeveloped or developing countries . The distinction between them is a different process but we can differentiate based on conditions like economic growth , GDP, employment rate , population, etc. Let's understand how we can say whether the country is developed. ADVANCE OR DEVELOPED ECONOMIES An advanced or developed economy is one, which carries on production with a large amount of machinery and advanced techniques. An advanced economy employs its human and other resources to the maximum extent possible.  The productive efficiency of a developed economy is of a very high order, and the per capita income is also high. Consequently, people in these countries enjoy high standards of living.  England, the U.S.A, France, west Germany, etc, are advanced economies. These economies are inhabited by over one-fourth of the entire population of the world. ADVANCED ECONOMY Advanced Ec
