Software Engineering – Examples of Applications and Hardware
Software is simply a set of instructions that tell a specific computer how to perform. This is different than physical hardware, in which the machine is assembled and actually does all the work itself. In software, the user controls what the machine does. Software programs are used to aid in the execution of other software programs, such as computer games. In most cases, a user will not know how to do anything without using a piece of software.
The execution of the computer software programs is controlled by hardware. In this case, the hardware that operates on a typical personal computer is the machine code. Machine code is nothing more than a series of zeros and ones that are ultimately interpreted by the application software. Software applications make use of the machine code to tell the computer what to do. For example, when someone types a word into a word processor program, the machine interprets the text that is typed, converts it into actual characters, and then gives a result back to the user.
Engineers create large software application programs by combining programming with science and math. These engineers are able to create the best designs for machinery, automobiles, and many other devices. However, these engineers often must use manual coding in order to accomplish their task. Engineers are also very important in the field of aeronautics, because the designs of aircraft and spacecrafts require large amount of precision. Engineers also play a large role in the production of computer hardware, especially the motherboard of a computer.
There are two major types of application software. There is a type of application software that can be run on a personal computer in which case it is known as stand-alone application software. Stand-alone software does not have any kind of connection to the underlying hardware or operating system like shared application software does. Stand-alone system software is mainly used for programs that must be used on one’s own computer. Examples of this type of application software are fax software, spreadsheets, database management software, and the like. On the other hand, a type of utility software is what most people think of when they hear the words “utility software.”
Utility software applications are used in many different fields. For example, many software engineers do work as consultants. In this field they help companies design and develop new software systems that will be beneficial to their clients. In some cases, an engineer will specialize in a particular field, such as network engineering, security, or information technology (IT). These experts help to create new software systems that will be of interest to a company’s customers. Utility software engineers may also work as consultants, helping companies create better storage systems, networks, and so on.
Some other examples of application software are web browsers, office suites, e-mail programs, online stores, and mobile phones. Examples of hardware include cell phones, digital cameras, desktop computers, laptops, personal digital assistants (PDAs), printers, fax machines, network servers, personal digital assistants (PDAs), smart phones, game consoles and more. The list of hardware is almost endless, which can make it difficult for software engineers to keep their ideas on track. As technology changes rapidly and grows rapidly, software engineers will have to keep up too.
