We can define the action of programming or developing as an IT branch which is in charge of the design and writing of instructions for a computer to execute in order to complete an operation or solve a given problem.
A process is a set of instructions that the computer will execute in order to provide a certain result or outcome. A set of processes to perform several related tasks as one single entity is known as a program.
For example, a process could be the one designed to collect the information needed in order to create a new client to whom an invoice should be sent to. A second process, could be the calculation of the VAT for the invoice and a third could be the detailed information needed for each product purchased. As a whole, these processes would make up an invoice program.
What's a programming language?
A programming language is the main tool that a developer has to create a program. A programming language is made up of keywords and symbols that make up a language syntax and a set of rules for the correct use of these. For example, for our blog, we will be discussing C# which is an excellent example of a programming language.
So, a C# program, or application, will be composed by source code with the instructions for the program to perform.
