Programming language 

best programming languages

Programming language is a language or tool by which the program (software) is created. The type of language is used to communicate and to directly communicate with the computer, as well as the English language you use. Some kind of programming languages are also in the programming language, and the words are symbols and are also grammar. There are many programming languages that are divided into the following two squares.

about computer programming languages

(1)Low Level Programming Languages

Programming languages that can only understand the computer. Low Level LANGUAGE is called Low Level Language Computer. This is the exchange that computers do not  directly understand. That is why it does not need to translate the instructions written in. Therefore, the program written in it is a fast task. But it is very difficult to develop the program because it is very important to know the computer level of the computer. The Low Level Language is the following two types

(1) Machine

Machine language is the language of computer. The computer only understands the instructions written in machine language and can execute. Instructions written in machine language are 0,1 in the form of two digits, which is why it is also called binary language. Programs created in machine language are not portable. That is, the computer built into them can be run only in the same computer and not in any other computer.

(2) Assembly

Due to the instructions points written in the machine, it only makes computers. It is only aware of the writing. It has a very difficult task to write in it. That's why a new language was created to write instructions, which is called Assembli language. In it, the instructions are written as words of English, which is called Mnemonics. The later computer is translated into machine language with the help of the assembler, the computer understands it. The program created in Assembli language is not fully portable. They need to be transported to run on another computer.


(2) High Level Programming Languages

Programming languages ​​that both computers and users can call are called High Level Language. There are currently a lot of high level languages ​​available, who can develop programs by learning very easily. The computer does not understand the programs written in High Level Language directly. Therefore, they need to be translated into Machine language with the help of Compiler or Interpreter. After this the computer can understand and execute it. Some of the main high level languages ​​are

FORTRAN

Fortran is a short form of word formula translation. It was developed by the IBM John Backus in 1957. It is used primarily to solve scientific and mathematical problems. It is called the first high level language. Also this world is the first standard language too.

COBOL

Cobol is the short form of word Common Business Oriented Language. In this year, the development of Grace Murray Hopper was in USA . It is used primarily for creating programs related to business and business data processing.

BASIC

The full name of Basic is the beginner's all purify symbolic instructions code. It was developed in 1964. John Kemeny and Thomas Kurtz developed. This language is used primarily to teach programming programming. Therefore, it is also called the foundation stone for other languages.

Pascal

Pascal language name is great named named Biseise Pascal. Its development was done in Niklaus Wirth in 1970. It was mainly developed to create System Software. It is also called Block Structured Language.

C

The C development of the year was in the United States of America. At the United States of America. It was developed by scientific Dennis Ritchie. Its name was hence because its e-language name was B. It is used primarily to create System Software but it can be made all kinds of software with this help. It has the characteristics of both High Level Language. That is why it is also called Middle Level Language.

C++

C ++ language development BJARNE STOURTRUP was in the 1980s at the United States of America. In this year, the development of this language was adding a lot of new features in the language. Therefore, the name of C ++ is kept using the C ++. Mainly used to make software software, but all kinds of software can be created. This is the main difference in C and C ++ that supports the procedure oriented programming (POP) technology to make the program while C ++ object supports the Oriented Programming (OOP) technology.

Java

Java language development was made in Sun Microsystem in 1990. It is also an object oriented programming language that is used primarily to create applications related to website. Application created in all devices like-desktop, laptop, tablets, go on smartphone. Therefore it is also called Platform Independent Language.


Visual Basic

Visual Basic Language Development was done in 1991 . It is also an object orient programming language which provides a software to create software from drag and drum method in graphical interface. It makes it easy to make software without learning coding. That's why it is also called userfriendly language. It is used primarily to create application software.

Introduction of Computer

Organization of Computer System 

The creation of a computer is made up of many units and devices called components or components of the computer. All these units and devices work together, so the computer is also called a computer system. Its structure consists of the following units

Fig. Block diagram of computer

(1) Input Untit 

is the device that we input your data or instructions in Computer. There are lots of input diet that computers is directed to the CRU of the computer that he should do? What is the key to the most important input device of keyboard and mouse computer. Apart from this, there is some other important Input Device is follow-up: Joystick, Trackball, Touch Screen etc. The input Device main do the following

Users accept data inputed. 

(B) Converts the data from our language (English) to the computer's understandable language (Machine / Binary).

(C) Binary data is sent to the System Unit for processing.

(2) The System Unit System Unit is also called the CPU is Central Processing Unit. Its Hindi name is the Central Processing Unit. This is the most important part of the computer. Without this the computer system can not be completed. This connects all the computer's Devices like Keyboard, Mouse, Monitor, Printer etc. It is also called Brain of Computer. Its main function is to execute the program (Execute) and to process the data. In addition, the CPU also controls the functions of all sections like Memory, Input, Output Devices. CPU has three parts

(A) ALU 

The full name of Alu Alu is Arithmetic Logic Unit. This unit does not have a variety of actions (add-added, addresses, partners, and logical activities (comparison and decisions). Alu Controls instructions from UNIT. This receives data from memory and returns to the information in memory. After the work of Alu, the speed of the work (Speed) is very fast. This makes it an electronic circuit which is capable of calculating binary arithmetic.

(B) Memory Unit

Keeps the data and instructions in the computer and receives the information you received by Input Device. It is also called the memory of the computer. In other words, the location of the computer is called the memory where all information, the basis and instructions are kept by the store. This main work is to be stored in the values and stores the data being procedures. This memory is an integral part of CPU. It also says the main memory of the computer and the main memory of the computer, internal memory.

(C) Control Units

The full name of the CU is the Control Unit. CU controls and operates the operation of all the hardware of the computer. This controls control the Output actions, as well as directs the exchange of data between Memory and ALU. These programs receive the instructions from the memory to execute the program. Its main function is to obtain order sequentially from memory, interpreting it, and converting to electrical signals and reaching the appropriate Devices.

3) Output Unit 

Output Unit is the device that provides data input by the user as a result. There are lots of Output Device in Computer which present the results of inputted data and processing for us. Monitor and Printer are two most essential output devices. Apart from this, there is something more important Output Device - Speaker, Projector, Touch Screen etc. The Output Devices mainly perform the following functions-

(A) The system accepts results after processing from the unit.

(B) Convert the results from the computer to the understandable language (Machine / Binary) to our language.

(C) Displays the results for us on screen or printed on paper.
