programming languages in Computer

Written by admin

The process of developing and implementing various sets of instructions to enable a computer to do a certain task. These instructions are considered computer.

Computer Programming Languages:

programming languages

Computer programming languages allow us to give instructions to a computer in a language the computer understands. Just as many human-based languages exist, there are an array of computer programming languages that programmers can use to communicate with a computer.

The portion of the language that a computer can understand is called a “binary.” Translating programming language into binary is known as “compiling.” Each language, from C Language to Python, has its own distinct features, though many times there are commonalities between programming languages.

What is a language?

Language is the medium of communication to share ideas, opinions with each other. For 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, a 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:

types of computer 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

1) Low-level programming languages :

These are machine-dependent programming languages such as Binary (Machine code) and Assembly language.

These are machine-dependent programming languages such as Binary (Machine code) and Assembly language.

2) High-level programming languages:

These are the machine-independent programming languages, which are easy to write, read, edit and understand.

Languages like Java, .Net, Pascal, COBOL, C++, C, C# and others (which are very popular now to develop user-end applications). These languages come under the high-level programming language category.

High-level programming languages have some special keywords, functions and class libraries by using them we can easily build a program for the computer.

Middle-Level programming language:

Since there is no such category of computer programming languages, but the programming languages that have features of low level and high-level programming languages come under this category.

There are three main kinds of programming language:

Machine language
Assembly language
High-level language

Machine Language :

computer languages

Humans do not like to deal in numbers alone-they prefer letters and words. But, strictly speaking, numbers are what machine language is. This lowest level of language, machine language, represents data and program instructions as 1s and Os-binary digits corresponding to the on and off electrical states in the computer.

Each type of computer has its own machine language. In the early days of computing, programmers had rudimentary systems for combining numbers to represent instructions such as add and compare. Primitive by today’s standards, the programs were not convenient for people to read and use. The computer industry quickly moved to develop assembly language

Assembly Languages :

Today, assembly languages are considered very low level-that is, they are not as convenient for people to use as more recent languages. At the time they were developed, however, they were considered a great leap forward. To replace the Is and Os used in machine language, assembly languages use mnemonic codes, abbreviations that are easy to remember: A for Add, C for Compare, MP for Multiply, STO for storing information in memory, and so on.

Although these codes are not English words, they are still- from the standpoint of human convenience-preferable to numbers (Os and 1s) alone. Furthermore, assembly languages permit the use of names- perhaps RATE or TOTAL-for memory locations instead of actual address numbers. just like machine language, each type of computer has its own assembly language.

High-Level Languages :

The first widespread use of high-level languages in the early 1960s transformed programming into something quite different from what it had been. Programs were written in an English-like manner, thus making them more convenient to use. As a result, a programmer could accomplish more with less effort, and programs could now direct much more complex tasks.

These so-called third-generation languages spurred the great increase in data processing that characterized the 1960s and 1970s. During that time the number of mainframes in use increased from hundreds to tens of thousands. The impact of third-generation languages on our society has been enormous.

Digital Computer Simulation:

A discussion of simulation languages, their characteristics, the reasons for using them, and their advantages and disadvantages relative to other kinds of programming languages

. Simulation languages are shown to assist in the design of simulation models through their “world view,” to expedite computer programming through their special purpose, high-level statements, and to encourage proper model analysis through their data collection, analysis, and reporting features.

Ten particularly important simulation programming language features are identified: modeling a system’s static state, modeling system dynamics, statistical sampling, data collection, analysis and display, monitoring and debugging, initialization and language usability.

Examples of each of the four simulation languages, GPSS, SIMSCRIPT II, SIMULA, and CSL, are used to illustrate how these features are implemented in different languages

. The future development of simulation programming languages is dependent on advances in the fields of computer languages, computer graphics, and time sharing. Some current research is noted, and outstanding research areas are identified.

Python:

python undoubtedly tops the list. It is widely accepted as the best programming language to learn first. Python is fast, easy-to-use, and easy-to-deploy programming language that is being widely used to develop scalable web applications.

YouTube, Instagram, Pinterest Survey Monkey are all built in Python. Python provides excellent library support and has a large developer community. The programming language provides a great starting point for beginners. Talking about those who are looking for a better job, you should definitely learn Python ASAP!

Java :

Java is another popular choice in large organizations and it has remained so for decades. Java is widely used for building enterprise-scale web applications. Java is known to be extremely stable and so, many large enterprises have adopted it

. If you are looking for a development based job at a large organization, Java is the language that you should learn.

Java is also widely used in Android App Development. Almost any business today needs an Android Application owing to the fact that there are billions of Android users today. This opens up a huge opportunity for Java developers given the fact that Google has created an excellent Java-based Android development framework – Android Studio.

C/C++:

C/C++ is like the bread and butter of programming. Almost all low-level systems such as operating systems, file systems, etc are written in C/C++. If you wish to be a system-level programmer, C/C++ is the language you should learn.

C++:

C++ is also widely used by competitive programmers owing to the fact that it is extremely fast and stable. C++ also provides something called as STL – Standard Template Library. STL is a pool of ready-to-use libraries for various data structures, arithmetic operations, and algorithms. The library support and speed of the language make it a popular choice in the High-frequency trading community as well.

PHP:

PHP is among the most popular back end programming language. Though PHP is facing tough competition from Python and JavaScript, the market still needs a large number of PHP developers. Those who wish to join a reasonably well old organization as a back-end developer should aim to learn PHP programming.
