Computer programming is the creative process of building and designing an algorithmic computer program to do a certain specific job or to achieve a particular computing result. It is also called as software engineering, because the people involved in its formulation and design must also be skilled in other fields as well, such as software development, database programming, or computer systems design. Programming is an activity that has been carried out through different techniques and platforms by different people over the years. There are different approaches to programming. Today, computers can be used to carry out programming, making it a very important subject nowadays.
The history of computer programming dates back at least 4000 years. It has become an intricate part of everyday life. In the past few decades, programming has turned into a highly competitive career option. As more technological changes are introduced, the area of computer programming has become even more specialized. As a result, computer science has become one of the major fields alongside medicine, engineering, and math in the academic curriculum.
Traditionally, computer programming was done in large, complex environments, such as research laboratories. This has changed, with more focus on smaller, modular, open source development platforms and greater user control. As computers became more powerful, programming began to concentrate more on the machine than the person. This is not to say that all programmers are now machine coders; just that it has become a majority trend. Today, there are a lot of sophisticated machines used in these environments, making it a little harder for a computer programmer to distinguish their own code from that of others.
One reason why programming has become so specialized is because computers have become so much more capable of running programs. Originally, computer programmers wrote the source code, which was just a series of instructions that the computer would follow. Today, computers can carry out complex programs much faster than that, which has led to a big change in the type of programming done. Today, programmers write machine code, which simply means the computer reads and executes a series of instructions (code) without any human supervision.
Programmers in the past used a very limited vocabulary. Today, computers have a plethora of vocabularies for different uses. In the early days, programmers wrote ordinary text or simple sentences, with no ability to express complicated thoughts. New languages have been developed over the years to take advantage of new technologies like the spread of word processing, which enables people to type information into a document much more quickly and easily.
Another reason why programming languages have expanded over time is because computers themselves have improved significantly. Programs written for a different type of environment can run on very different machines. Computer languages are designed to run on particular machines, so they must be coded to specific operating systems. As more types of machines are created and made available, computer programmers have had to learn different types of programming languages to be able to target these different types of platforms.
Programs written for different operating systems vary greatly in complexity. Windows, a Microsoft-oriented operating system, has a number of different programming languages. Macs, a Unix-like operating system, also have their own programming languages, although the scope of these varies greatly as well. Linux, which is not similar to either Windows or Macs’ languages, does not have a large number of built-in operating systems, but Linux programs often run on a number of different operating systems.
The complexity of programs written for various operating systems is one reason why programmers write different types of programs. Programs written for a particular operating system have to deal with each specific system’s terminology, which often leads to programmers having to learn a number of different programming languages. This is another reason why a software developer does not need to specialize in computer science. A software developer can choose to specialize in a particular aspect of software development, such as database design, user interface programming, search engine optimization, or algorithms. Programmers who learn enough about a particular subject to work with it on multiple platforms may choose to specialize in only that aspect of the field. Whatever the programmer’s preferences, he must first study the field he wants to work in.
