Basic Programming

In this essay, we will show you how to organize and understand the workings of your computer.

Computer beginners are not uninterested in managing the computer; new computer users are frequently involved in learning how everything works. However, we can still introduce you to some of the simplest programming concepts – starting with instructions.

Instructions are the guidelines that the computer follows to perform an action. Developers create instructions for items like buttons, for instance, to make them work within a program.

The instructions in a program are fairly useless until they have some data to follow. Developers either provide the program with some data to work with (a list of names or numbers, for instance), or they create the program to produce its own data.

Sometimes, the data comes from some other source such as the computer or the Web the program exists on. The data that the program gets is known as input and the output the system produces is known as output.

All these languages differ in the way they communicate with a PC; the instructions they follow are very specific. Not a single order of one language can be exchanged with the language or instructions of another. But they can all be used to control a PC.

At the moment, it would not be possible to teach you how to program any language in one training or article. Nonetheless, you might be surprised to discover that computer knowledge increases in general, and it may help reduce the fear and anxiety associated with using a new computer.

Programming is developing a sequence of instructions that enable the computer to perform some tasks. The people who program computers (called programmers) use a programming language to communicate with a computer. You may have heard of some of these languages before, such as C, Visual Basic, or FORTRAN.

They are all capable of achieving the same goals and performing the same tasks. A programmer chooses one language with a simple choice.

Other times, the data is unknown. If the program worked with a simple algebra equation like “x + 5 = y,” the variables “x” and “y” could be unknown bits of information. Or if a program were to calculate a date “x” days from today, the variable “x” could be an unknown bit of information until we tell the program what “x” is. In programming, it is sometimes necessary to use unknown bits of information.

That is when conditions are handy; they allow a program to perform an action based on the occurrence of the previous command. By using this type of instruction, we can instruct a program to do something if the “x” variable in our latter example turned out to be 9 days, and then do a different thing if the variable turned out to be 31 days.

As we mentioned earlier, you can use a programming language to control your PC. You can program your PC to perform mathematical tasks, fill out web forms, write an email message and send it out, or a variety of other activities by using simple instructions.

If you’re interested, you may find Visual Basic one of the easiest programming languages to learn.

Conditions, data, variables, and instructions help develop the most basic programs, and there are certainly more aspects of any programming language. But when they are entered into a programming language and compiled to create an executable file (a file ending with the “.exe” extension), they become a software program.

Visual Basic is an object-oriented programming language, and it automatically codes much of a program the moment a programmer drags a button onto a screen.
