A programming language is a language used to give commands to a computer. These languages are used to program software and applications. The first computer programming languages were called machine languages. A machine language’s code looks like machine code, which was nothing more than a series of numbers and letters that told the computer what to do. Machine languages had very simple commands and could only be used by programmers with a high level of knowledge and skill. Programs written in machine languages took a long time to develop and were not very efficient.
In the 1960s, two major things happened to make programming easier for developers. The first was the invention of assembly language, which gave developers a way to write programs in a language similar to the target computer’s machine language. Assembly languages still used numbers and letters but were more readable. Assembly languages allowed developers to write smaller programs that ran faster than those written in machine languages. The second major development that made programming easier for developers was the invention of high-level programming languages. High-level languages allowed developers to write programs using words and sentences instead of numbers and letters. High-level languages made it easier for people with little or no programming experience to create programs. Mainframe computers from IBM, Digital Equipment Corporation, and others were the first machines to use high-level languages, making them popular among companies who needed to quickly develop large amounts of software, such as banks and insurance companies. In the 1970s, personal computers started appearing on store shelves. These personal computers revolutionized computing by allowing average people to have their own computers instead of just companies and universities. Personal computer manufacturers struggled to compete with each other because they all used different kinds of operating systems. Microsoft created a new kind of high-level language called BASIC that became the standard for personal computers. Microsoft developed several versions of BASIC that supported different types of hardware. BASIC became so popular that it was available on most home computers during the 1980s and 1990s.
Computer programming languages can be grouped into three major categories: procedural languages, object-oriented languages, and functional languages. Procedural languages are based on statements or commands that are executed one at a time by the computer. Object-oriented languages are based on objects that contain attributes and methods, which are data and functions stored within an object. Functional languages are based on mathematical functions that are executed either sequentially or in parallel. Languages also vary in their size, which refers to how many lines of code the language can hold at one time, and their structure, which refers to how the code is structured inside the language. Some languages offer operators for mathematical operations while others offer functions for mathematical operations. Some languages offer loops for repetitive actions while others do not offer loops at all. Some languages offer classes while others do not offer classes at all. Finally, some languages allow function definitions while others do not allow function definitions at all.
Understanding the form tag
The form tag allows you to create an HTML form on your webpage. Forms help you gather information from users on your site through text boxes, dropdown menus, radio buttons, checkboxes, etc. Users will fill out the form fields with information about themselves, then submit them to you via email or through another form action.
