A computer program is a set of instructions that describe what a computer is to do. We can think of a computer’s memory as a computer program, and each instruction is called a “word.” A word can be one or more letters, numbers, or symbols. Computer programs are stored in the computer’s memory and are executed by the computer.
The instructions contained in a computer program are compiled or processed when the computer is run. The most common compilation method is known as “disassembly.” There are many other methods, but all of them run the instructions through a compiler to create a program that is compiled for a specific processor architecture.
A programmer creates computer programs by creating a text file and then putting it into a form that the computer can understand. To do this, he first needs to learn a program. Then he begins by coding an instruction that is included in the document, which is called a source code. The source code describes how to accomplish a particular task with the program, and is usually included with the document.
The programmer also has to learn how to make his code format so that the processor can read the information it requires to process computer. The processor will look at the source code and determine how the instructions should be executed.
As far as computer processors go, there are two types, namely, AXIOMs (also called ROMs) and AXIOMs that translate between the source code and input/output commands. Input/output commands (I/O) are commands that tell the computer how to act. There are also a couple types of I/O, but the processor itself takes care of it.
When we talk about programming, we’re not just talking about creating computer programs. We’re talking about writing programs that actually instruct the computer how to carry out the instructions we give it. That is where a programmer comes in.
If you could take any computer, regardless of processor type, and turn it on, it would be programmed to perform a certain task. That task would be specified in the source code. Without the programmer, that task would never be carried out.
The most famous computer programmer of all time was Alan Kay, who invented the personal computer. His discovery led to the development of the personal computer itself, a device that actually turns your computer into a computer.
Just as humans can be made to do something that is not physically possible, so can computers be made to carry out tasks that are not possible. Computer scientists have spent years building software that actually enables computers to make use of the instructions within the source code. Without that software, computers would never be able to execute instructions.
Some people wonder if computer science is the same as programming, but they are not the same thing. Programming is only a subset of computer science, while computer science is a subset of engineering, both branches of science.
Programming and computer science are closely related but are entirely different from each other. They have more in common than most people realize.
