Types of Languages

·         Low-Level Languages: A language that corresponds directly to a specific machine

·         High-Level Languages: Any language that is independent of the machine

There are also other types of languages, which include

·         System languages: These are designed for low-level tasks, like memory and process management

·         Scripting languages: These tend to be high-level and very powerful

·         Domain-specific languages: These are only used in very specific contexts

·         Visual languages: Languages that are not text-based

·         Esoteric languages: Languages that are jokes or are not intended for serious use

·         Interpreter : This is a convertor which converts high level language programme to low level language programme line by line.

·         Compiler : This is also a convertor which converts whole high level language programme to low level language programme at a time.

 

Types of High-Level Languages

Many languages have been developed for achieving a variety of different tasks. Some are fairly specialized, and others are quite general.

These languages, categorized according to their use, are:

1) Algebraic Formula-Type Processing

These languages are oriented towards the computational procedures for solving mathematical and statistical problems.

Examples include:

·         FORTRAN (Formula Translation)

·         PL/I (Programming Language, Version 1)

·         ALGOL (Algorithmic Language)

2. Business Data Processing

These languages are best able to maintain data processing procedures and problems involved in handling files. Some examples include:

·         COBOL (Common Business Oriented Language)

·         RPG (Report Program Generator)

3. String and List Processing

These are used for string manipulation, including search patterns and inserting and deleting characters. Examples are:

·         LISP (List Processing)

·         Prolog (Program in Logic)

4. Object-Oriented Programming Language

In OOP, the computer program is divided into objects. Examples are:

·         C++

·         Java

5. Visual Programming Language

These programming languages are designed for building Windows-based applications.Examples are:

1. What is a mobile application?

A mobile application (also called a mobile app) is a type of application designed to run on a mobile device, which can be a smartphone or tablet computer. Even if apps are usually small software units with limited function, they still manage to provide users with quality services and experiences.

Native apps

Web apps

Hybrid apps

 

3. Types of mobile applications

Mobile applications come in many shapes and sizes. Here are the most popular types of mobile apps to help you understand the current trends in the mobile landscape.

  • Gaming apps – this is the most popular category of mobile apps. You’d be surprised to learn how many users install games on their phones. Businesses invest an increasing amount of time and resources into creating games and mobile versions of well-known stationary games because it’s such a profitable market. According to a recent study, mobile games account for 33% of all app downloads, 74% of consumer spendings, and 10% of all the time spent using apps. The most successful mobile games like Candy Crush Saga or Angry Birds become known all over the world.
  • Business or productivity apps – these apps hold a large chunk of the market today because people are increasingly prone to using their smartphones and tablets to perform many complex tasks on the go. For example, apps can help them to book tickets, send emails, or track their work progress. Business apps are geared at boosting productivity and minimizing expenses as they allow users to complete a wide range of tasks, from buying new cartridges for office printers to recruiting a new office manager.
  • Educational apps – this category includes mobile apps that help users gain new skills and knowledge. For example, language learning apps like Duolingo have become incredibly popular because they give users the flexibility they look for in learning. Educational game apps are an excellent tool for kids. Many educational apps turn out to be popular among teachers too, who use them to organize their teaching process better or educate themselves further.
  • Lifestyle apps – this broad category of apps spans shopping, fashion, virtual fitting rooms, workout, dating, and diet apps. These apps basically focus on various aspects of personal lifestyle.
  • M-commerce apps – the most popular shopping apps like Amazon or eBay offer the experience of their desktop versions to mobile users. Mobile commerce applications provide customers with convenient access to products and seamless payment methods for an optimal shopping experience. Learn more about mobile commerce definition and types of mobile commerce.
  • Entertainment apps – these apps allow users to stream video content, search for events, chat, or watch content online. Social media apps like Facebook or Instagram are great examples. Moreover, video streaming apps such as Netflix or Amazon Prime Video have become incredibly popular with users all over the world. These apps usually boost user engagement by notifying members about updates and newly added products.
  • Utility apps – these are so obvious that we barely even realize that we’re using them. In fact, utility apps usually have the shortest user session times – people use them to get things done and then move on. The most popular types of utility applications are barcode scanners, trackers, or healthcare apps.
  • Travel apps – the main idea behind this category is helping users to travel easily. Travel apps transform a smartphone or tablet into a travel diary and guide that helps users to discover everything they need to know about the site they’re visiting. Most of the tourists are digitally savvy travelers who know how to use apps to their advantage. Can you imagine what traveling would look like without Google Maps, Airbnb, or Uber?
