Software Provides Functiionality

In our modern era, we rely on computers to do so many things for us, yet many people don't realize how important the computer software is that makes everything happen. From clock radios, to monitoring systems in our cars, to our mobile phones, and all the way up to the giant super computers that can manage space launches, nothing would function properly if it were not for well written computer programs.

Although we are squarely in the midst of an era where people reply on computers more than ever to do even simple tasks for us, many people are really not familiar with the importance of the underlying computer software that brings everything to life. From simple appliances like microwaves, to larger conveniences like automobiles, and from tiny cell phones to massive super computers, none of it could provide the functions we depend on if not for the essential programming that has been written for each use and function.

While we are truly in the middle of an era in which computers are part of virtually everyone's daily life, many are simply unaware of how important the computer software is to each and every computerized device we use. From the minute mobile phones of today to the giant super computers that manage the world's finances and space launches, nothing would be of any value if it was not for the programs that drive these devices.

While just about everyone uses a computer in some way, shape or form on a daily basis, there are relatively few people who understand how vitally important computer software is to the usefulness and functionality of even simple devices. From very basic items such as a digital watch, to handy innovations in cell phones, to the grand super computing behemoths that manage things such as space shuttle launches, none of these machines could function without the programming that gives them life.

Essentially all programs and applications for computers are a set of instructions designed to create particular outcomes. A computer program is a collection of these instructions that have a common purpose. A collection of related programs to carry out coordinated computing tasks is referred to as a package.

A good example of a software programming package would be an accounting-related application. This package might contain several different modules, or individual programs, that work together within the complete package.

One great example of a package of software programs would be an application that handles accounting related tasks. Such a package would have a number of modules, or independent programs, that function together to comprise a complete package.

One simple illustration of a software package is a comprehensive application that can handle the various aspects of accounting functions. This type of application package could be comprised of a number of smaller component programs, or modules, that are integrated and work together to deliver a complete accounting solution.

For instance, the accounting package might contain a bookkeeping program, an audit program, a data base management program, a tax preparation program, a time tracking and billing program or any number of other related programs. In many cases each of these kinds of accounting programs could stand alone, but they become much more powerful when they operate together as a complete package.

These kinds of packages that contain various modules, or programs, have become very popular because the data is shared between the various programs. This reduces the need to re-enter data and eliminates tasks of exporting and importing information from one program to the other. This not only saves time but it also significantly reduces the possibility of errors, because even when data is not re-keyed there are numerous possibilities for data to become corrupt when going through exporting and importing functions.

All computers operate with what is known as system software, or the operating system. This programming provides the very basic instructions for how the computer interacts with the user and how the various programs and packages operate. Windows is the most commonly used personal computer operating system, with the Macintosh OS X operating system being the next most common system. Other operating systems include Linux and Unix, which are often used in more high-end computing situations.

If you have computer work that needs to be done, then there are at least three components in play. The hardware is the first component which is actually what most people think of when talking about computers. The hardware includes the "box," the monitor, the keyboard, the mouse and any other physical components.

The operating system software is the second of the three components. Which operating system that runs on your computer will have a great deal to do with which programs you are able to operate and also will make a difference in how easy or difficult it is to use the computer overall. While Windows computers are more prevalent, many people say that the Macintosh computers are more user friendly because of the operating system.

The third component of any computer function is the software program or package that is being used to do the actual work. This goes back to the example of the accounting package. Without a specific program to carry out the accounting functions the computer is not particularly useful. It is the operating system and the specific programs that really are the most important aspects of accomplishing any significant work on any computer.

The last component of any basic function of a computer comes into play through the software program that is being utilized to accomplish the actual task at hand. Going back to the example of the accounting package, without this final component the accounting related tasks could not be accomplished. Essentially, without these specific programs, or applications, the computer itself has very little functionality.

The final of the three components of any computerized task is the specific software program that has been written to handle the required work. This relates back to the accounting program example which provided the specific functions related to the accounting tasks that needed to be done. Without these specific applications, a computer alone, even with a good operating system, will not provide many solutions or much functionality.
