Coding is aimed at bringing to life a program that functions in a prescribed manner, the code can be in the form of modified version of a source already in existence or a brand new one, source code is written in programming language, and proficient in various subjects including full knowledge of the application domain specialized algorithms and formal logic.
Whatever you may consider programming to be (an art, craft, or engineering discipline), competent programming is widely regarded as the measured application of all three towards achieving an efficient and evolvable software solution.
A license is required in many countries of the world for an individual to operate as a professional software engineer, as proof of accreditation with a recognized IT institution, and the concept of devices following pre-defined set of instructions dates back to the Greek mythology, and the earliest known were the Al-Jazari’s programmable Automata in 1206.
Al-Jazari had several programmable sophisticated machines and one of them was the castle clock renowned for its concept of variables that could be manipulated by the operator as necessary. The developments that led to the of modern day computer programming were the synthesis of numerical calculation, predetermined operation and output along with a way to organize and input instructions in a considerably easy fashion for humans to understand and produce.
Early computer programmers utilized plug boards for the myriad complex calculations needed for the early days machines – data and instructions were stored on external punch cards arranged in program checks, while the ground breaking invention of the Von Neumann architecture enabled computers programs to be stored in computer memory, instructions were singularly crafted into a machine using binary notation.
Improvements led to the formulation of assembly languages that allowed programmers to enter instructions using text format such as abbreviations for each code rather than of a number, and as time went on the languages became even more sophisticated enabling programmers to execute nifty things – as a result commercial programming languages such as COBOL were developed.
Data storage devices and computer terminals became more affordable allowing the creation of programs through typing directly into the computers, high level languages incur greater overhead and the increase in speed of modern computers has resulted in enhanced practicality as regards the use of the languages, which are far much easier to learn. They also require less code to develop excellent applications, and a good number of the programming forms are a direct result of offshore outsourcing.
