Have you ever wondered what is software and why are we in such a great need of it?

Computer software constitutes a procedural program used to schedule instruction streams onto a computer running process. It provides the capacity to run certain tasks, tasks that can only be undertaken with software programs. Software programs are specially designed to perform certain tasks and, through its usage, a PC is enabled to perform applications.

A computer`s software consists in applications of the software, such as words processed to perform productive chores for its users. A system software engages an operating system together with the hardware, for the latter to run the necessary services for users-interfaces and apps. Additionally, as mentioned previously, we can observe that for a computer operating system to be able to run its tasks and application, interoperability between software and hardware is required.

These being outlined, we shall distinguish between three types of computer systems: system software, programming software and application software.

The system software incorporates features that have the task of enabling the user's computer to run both the computer hardware and the computer system. It also runs a multiple task performing, regarding the operating systems, the device drivers, diagnostic tools, windowing systems, utilities, and so on. Its major priority and goal is to protect the applications programmer, particular the computer complex, memory and other hardware accessory devices that are attached to a computer (printers, readers, display, keyboard, scanner, communications etc.).

The second important part of the computer system, the programming software, provides tools and assistance for the user to write through computer programs and software with different programming languages, that best suits the operator of the PC. The featured tools are linkers, debuggers, tracing, a text editor, compiling and much more.

The last computer system is represented by the application software which enables the user in achieving one or more tasks of its interests.

We have already defined and understood what a computer system is and what features it incorporates. It is important to determine which software must be assessed because not all software combine and work at their maximum parameters. We also have to consider antivirus protection or any other task / application of the PC.

Let`s take for example an operating system such as Windows 95 or Windows 98. It is endowed with the latest software, no matter what application the latter is installed for, since the risk of it to not work properly at its maximum functional parameters becomes a real fact.
