There is a huge list of different type of computer software. Today programmers can create any software you can imagine. Software development companies are increasing in number. You find such companies online based in India, Romania, UK and many other countries. At any single point in time, there are thousands of software jobs posted all over the internet like software engineering jobs, software testing job and software sales jobs.

What is software piracy? There are several kinds of software piracy. The bottom line is when software is pirated, the developer does not receive compensation for their work. Programs presented by Online Software Engineering Schools guide students to better understand the various tasks and specialties that aid in software product development.

Computer software:

The term software is generally used for computer software that is an essential part of the computer system. It stores and process all encoded information or computer instructions on PC.

For example Windows, antivirus, antispyware, Ms Word, Photo shop, FTP software and many more.

Software is the short name given to computer software. Anything, which can be stored automatically, is known as software. Both hardware and software are different from each other. They are responsible for the proper functioning of the PC by making them fit for use. Software is processed by computer systems, programs and other data. Being totally opposite to hardware, which is used to store or execute the software, software is connected with random access memory and then carry out the work in central processing unit.

Computer games can be categorized mainly into PC games that are played in your computer after installation using the CDs that contain the software, downloadable pc games, and the online games. Keeping a diary of your computer can be a valuable asset if something goes wrong. Imagine for a moment the consequences if your hard drive failed or worse, someone stole your computer. Use a backup software. Hackers are diligently at work everyday trying to find the weakness in your system so that they may be able to steal your personal information.

The world online can be a scary place and sometimes it can get downright nasty. From viruses and spyware to internet identity theft, the information stored on your computer is under constant assault and should be protected at all costs. Others would simply like to create trouble and destroy your hard drive. That is why you need antivirus and anti adware and spyware software. Most antivirus protection software protects your computer from known viruses and Trojan horses. If a new virus is detected, your virus software will automatically download the new definition so that your computer will be safe.

It’s a known fact that the majority of personal computers have corrupt files with errors on them. Problems with Windows Registry usually result in Windows crashes. That is why a Registry software was created.

Business software include, ftp software such as Filezilla, mailer (used to send out email), website design software such as Nandu or any other html composer, TomahawkPDF software (Creates pdf documents) and many more.

That sums up what software means and the different types of computer and business software.

Paulita Lobrin asked:


Before, whenever a developer is tasked to perform programming or coding, he immediately would jump to it, start programming with or without full knowledge of what the system would look like, how the features are arranged, etc. It is probably okay only if you’re just building a very simple system. However, if you’re building a complex and sophisticated system, it will take a long time for you to finish. Worse, you start to suffer from “groping in the dark” syndrome since your full of ideas, you want to implement them all, but you tend to forget about them because other features need to be prioritized.

That was before. Now, whether an IT system is small, medium or large scale, it is important to have a proper software/system development plan from beginning to end. It saves time, features of the system are well documented and will not be forgotten regardless of priority, and above all, there is proper management and execution of plans.

System Development Life Cycle (SDLC) models help in the complete development of a system, right from the conceptual stage to the customer delivery stage. SDLC is very useful if one has a complicated system to build. SDLC is the overall process of developing information systems through a multi-step process, from investigation of initial requirements to analysis, design, implementation and maintenance.

To properly illustrate the SDLC models, I shall present them in bullet form.
1. Waterfall Model
• One of the older SDLC models
• Each single step in the process of system development is first written down in the form of specifications and reports. Only then are the actual phases initiated in practice
• The execution of a project appears as a sequence of stages in which the output of each stage becomes the input for the next
• The stages in Waterfall method are divided into the ff:
1. Project planning / feasibility study – commonly known as Requirements Stage. It is in this stage that developers/stakeholders determine the project goal
2. System analysis – refines project goals into defined functions and operations. It also analyses end-user information needs (Specification stage)
3. System design – describes desired features and operations in detail (Design stage)
4. Implementation / Coding (Implementation stage)
5. Integration and testing – brings all the individual system components into one, then testing it for errors, bugs, etc. (Integration stage)
6. Acceptance, Installation, Deployment – final stage of development where the software is put into production
7. Maintenance – this goes on apparently forever since changes, additions, etc are always essential, important and needed in a software application especially in the area that involves business and monetary transactions.
• Drawbacks
1. Works well on simplistic activities
2. Assumes that the only role of users is in specifying requirements and that all requirements can be specified in advance. Unfortunately, requirements grow and change
3. It is, thus, well suited to projects that has low risk in the areas of user interface and performance

2. Spiral Model
• Most generic of the models. Most life cycle models can be derived as special cases of the spiral model
• Set of important requirements are selected for each prototype. Thus, developers can split the requirements and work first on those with high priority
• Employs a risk management approach to software development especially in the stages of Specification, Design, Implementation and Integration
• Emphasizes the need to reiterate earlier stages a number of time as the project progresses
• Actually a series of short waterfall cycles, each producing an early prototype, representing a part of the entire project. It’s like using the waterfall model as guide in doing one prototype only.
• If one prototype is finished (except perhaps the polishing of graphics), a developer can proceed to the next prototype. Build, test and integrate to the first prototype
• Helps demonstrate a proof of concept early in the cycle
• Incorporates prototyping and software quality objectives
• Gives early focus to reusable software
• Accommodates life cycle evolution, growth and requirement changes
• Focus on early detection and design (architecture) flaws
• Useful in hardware-software projects

3. Build and Fix Model
• Crudest of the models
• Implementation of system without specification nor design
• May work for small scale projects
• Code is written, then modified until client is happy
• VERY RISKY!
• I know of a developer who does just this kind of work strategy. He was given an assignment, but instead of planning properly, he will just code it immediately without specification or design. He improves it until his client is happy. If the client is dissatisfied, he doesn’t give a damn about it.

4. Rapid Prototyping Model
• Emphasis is on creating a prototype that looks and acts like the desired product in order to test its usefulness
• Develop a system with reduced capability
• Present to client for approval
• Once the prototype is approved, it is discarded and the “real” software is written.
• Develops specification with better understanding
• Exactly like the Spiral Model, where a prototype or only “shadow” of the real software is made, where the system (during implementation stage) is not that graphically perfect but features are functioning well for testing purposes
• Only difference is, in Rapid Prototyping, it requires client approval prior to the building of the “real” software

5. Incremental Model
• Divides the product into builds, where sections of the project are created and tested separately
• Each build contains an operational quality subsystem
• Each additional build, a new subsystem is integrated with the previous build
• You will notice that this model is very much like the Spiral Model except that instead of prototype, they’d rather call it builds. These builds, like prototypes, are tested separately first. Each build has a subsystem in Incremental Method, whereas in Spiral, subsystems may or may not be used
• Likely to find errors in user requirements quickly

6. Synchronize and Stabilize Model
• Type of Incremental Model
• Allows many teams to work efficiently in parallel
• A nightly compilation of builds of the entire project is made to piece together all current components
• An alpha release was done for internal testing, a couple of beta releases took care of a wider testing range outside the company. Finally, a release candidate leading to the final version, called a gold master, was released to manufacturing
• At some point before each release, specifications would be frozen and the remaining time spent on fixing bugs
• There is heavy emphasis in schedule management and perfection

7. Fountain Model
• Support Incremental Development
• Recognizes that some activities can’t stand before others, yet there’s a considerable overlap of activities throughout the development cycle
• Implies that you do some analysis, then some design, then some implementation
• Parallelism among various phases and iteration within phases
• Development of an object-oriented system that more likely to lead us to focus on sections of the whole known as clusters or subsystems
• Subsystems are collections of classes which work closely together
• Supports human learning and is recommended for most projects.

Software, computer programs; instructions that cause the hardware-the machines-to do work. Software as a whole can be divided into a number of categories based on the types of work done by programs.

The two primary software categories are operating systems (system software), which control the workings of the computer, and application software, which addresses the multitude of tasks for which people use computers. System software thus handles such essential, but often invisible, chores as maintaining disk files and managing the screen, whereas application buy software performs word processing, database management, and the like. Two additional categories that are neither system nor application software, although they contain elements of both, are network software, which enables groups of computers to communicate, and language software, which provides programmers with the tools they need to write programs.

In addition to these task-based categories, several types of software are described based on their method of distribution. These include the so-called canned programs or packaged software developed and sold primarily through retail outlets; freeware and public-domain software, which is made available without cost by its developer; shareware, which is similar to freeware but usually carries a small fee for those who like the program; and the infamous vaporware, which is software that either does not reach the market or appears much later than promised.

In addition to a computer’s speed the usability of the software and the ergonomic design of the physical components are important considerations.

Usability is the ease with which a person learns to use an application, as well as how efficient and effective it is. Ergonomics determines how people function in relation to their environment, and with respect to computers, how to make input and output devices easy, comfortable, and efficient to use. For example, curved ergonomic keyboards prevent wrists from bending at unnatural angles, making the user more comfortable and input faster.

When you know the specification of software, it’s much easier to decide to buy software that you want for helping your task.

Richard Romando asked:


In today’s technology savvy world, many companies are turning to the IT industry to assist them in managing their business endeavors. Many companies use maintenance software to help plan, procure, deliver, manage and improve reliability and utilization of their assets and physical infrastructures. It also helps them to support their core business, reduce risk, and maximize shareholder value. Maintenance software is an essential component of most businesses in industries as varied as software, fashion, hardware, food and electronic. One of the essential prerequisites is of course, that the maintenance software must be easy to install, use, maintain and update.

If the maintenance software is PC based, then it must be able to make full use of the extensive capabilities of Microsoft windows. Web based maintenance software are very useful and are more in trend nowadays. Most such software are open source and their programming codes can be revised or changed to suit the individual needs of a user.

The best maintenance software are those, which meet the distinct requirements of a client. Work management, physical assets management and resource management are the three basic components of most maintenance software that help improve a company’s analysis, production, sales and maintenance of products and services. They also help keep track of HR, finances, inventory and other sectors of a company. Different types of maintenance software like fleet maintenance software, asset maintenance software and production maintenance software are available which can be utilized to maintain the various sections or branches within a company. Buyers are advised to carefully evaluate the software in order to buy one that satisfies their specific requirements.

Several companies that sell maintenance software offer free downloads of maintenance software on the net. Users can try out these small versions to check out if the software is compatible with their business needs and then go on to buy the full product version from the company.

With the increased interest in Blogging (web Logging), many web hosting providers now provide an assortment of free usage, open source blogging software packages. Among the most popular of these blogging tools are B2evolution, WordPress and Nucleus. Each of these programs offer similar basic features, so the question arises as to which one is easiest to use and would be appropriate for the requirements of your particular website.

The answer lies in the true purpose of your blog website. If your primary goal is to share your opinions and ideas with the general public, you would want to utilize a different blogging tool than a user who was creating product blogs as a commercial sales effort. A blog for search engine promotion would have entirely different requirements. All of these uses are viable reasons to create a blog, however each requires different features to be successful.

WordPress Blogging Software

Available for free download at: http://wordpress.org/

It is hard to beat WordPress for general personal blogging. WordPress is an open source, state-of-the-art personal publishing platform with a focus on presentation and usability. Everything related to creating and updating your blog is available through an intuitive graphical interface. With WordPress there is no need to compile your work. You simply write your column. You then select the features you want and your blog is instantly created and published to your website.

If you are on vacation, you can schedule your uploads for some date in the future or even email your column to the server! The system allows multiple users with multiple blogs divided into categories and sub-categories. This allows multiple family members or friends to create their own blogs along with yours.

Easy customization and the availability of many “plug-ins” that provide more functionality (add new features as you learn) makes this software a very good choice for most individuals.

B2evolution

Available for free download at: http://b2evolution.net/

B2evolution is another advanced web log tool that features an integrated XHTML validator. It supports recursive subcategories, cross posting and has a really cool integrated “skinning” system.

The “skinning” system allows you to create multiple blogs in separate categories with different appearances for each blog. You simply “change the skin” for the blog to create a totally new look and feel.

The “skinning” feature, combined with the built in multi-user administration management tool, makes the system robust enough for more commercial endeavors, such as product promotion blogs. If you have much to publish with multiple themes, this is the software you are looking for.

Nucleus Blogging Software

Available for free download at: http://nucleuscms.org/

Though Nucleus is an extremely robust blogging tool in its own right, it also contains some powerful features that can provide benefits in promotion of your blog.

Nucleus offers the ability to optimize its URLS, creating simple page addresses that do not have and “&” or “=” characters. This makes the pages search engine (and user) friendly. Another great feature is the ability to show the contents of multiple weblogs on one page. This could allow a
website owner to manipulate the optimum text / keyword balance on pages for better search engine rankings.

Nucleus also provides RSS and Atom feeds that can be extremely helpful when promoting a website. If part of your blog’s function is to work as a search engine marketing and promotion tool, Nucleus is an exceptional software package.

Each of these blogging software packages offer the basic tools that you would need to create a successful blog and all three are PHP – MySQL open source (free to use) packages. You should try to select the software that helps you achieve the long term goal that you have in mind for your website based on the unique extra features offered by each.

Remember the good old days when you fired up your PC, all 64K of it? Boy, they sure don’t make them like that anymore, the PCs or the software that ran on them. If you’re attempting to run any of those gems on a turbo 4 gigahertz Windows 2000 or XP model, you’ve got a very long wait before you see anything but a blank screen. But it sure was fun playing with some of those not so great pieces of, well, whatever they were.

Need some reminders?

Why don’t we start with Visicalc for the Apple III? This was basically a Lotus 123 knock off. It ran in DOS, or the DOS equivalent for Apple and did basic spreadsheet functions. It wasn’t too fancy and the only interface you had was your keyboard, so forget about drag and drop or anything like that. The color was a very ugly yellow border on a green background. You could only have one worksheet at a time as there was no windows. This was around 1984.

Then of course you had all the great IBM PC gems like Lotus 123 itself. The look was basically the same as Visicalc, except it did come first. This actually did run in DOS 3.0 when it first came out. Versions ran all the way until DOS 6.0 until they finally came out with Windows 3.1.

In 1985 a company by the name of Aldus came out with a piece of software called PageMaker. It was made for the MAC and was one of the first desktop publishing softwares made. PageMaker actually started a whole desktop publishing craze for the MAC. A couple of years later they did release a version for the IBM series.

Also that year, the C++ programming language came out. This was supposed to be an all purpose language that was more powerful than the BASIC language that came with your PC. C++ was supposed to be for the more “serious” programmer. While it was able to get more into the core of the machine, it still pales in comparison to the languages of today.

We now move on to 1987. That year a guy by the name of William Atkinson came up with a piece of software called HyperCard. This was something that was supposed to make it easier to design in house applications. The program was made interactive instead of language based. Basically, what programmers did was build stacks and links between pages. The software itself was actually given away free with every Apple computer until 1992.

Unlike old movies that just seem to get better with time, old software is just that, old. Almost none of it can be run any longer unless it’s been updated, in which case it’s not old anymore. And the truth is, a lot of the old software of the early 80s and 90s was pretty bad. It just about was able to do what you wanted it to and if you tried to push most of it even a little, it would crash and burn on you.

No, there is no need to keep any of this stuff around any longer.

Sam Miller asked:


Software interface testing is just one among the many types of software testing that are used by software engineers for software development. Automated testing is one of the most common software test approaches these days. With this, engineers would not have to perform tests or quality assurance manually.

Nonetheless, automation of software test requires that a prior manual testing procedure should be set up and that this conforms to a formalized testing process. To automate the process, special software is used to control test executions, to ready pre-conditions or requirements for the test, and to compare actual outcomes to predicted results. While automated testing enables developers to save time and energy, manual testing is still needed for more complex tests. One of the testing methods that cannot be entirely automated is interface testing.

Interface testing is one of the most important software tests in assuring the quality of software products. In a nutshell, human beings are able to communicate with hardware through an interface. Interface is actually software that consists of sets of messages, commands, images, and other features that allow communication between a device and a user. Various companies use this type of software testing to make sure that their customers will not encounter any problem when using a particular software product once it is delivered to them. In addition, developers usually want their products to be supported by more than one language thus, their need to understand the interface. In this test, developers come up with changes or revisions and introduce these to a software application by taking note of the feedback from end-users. Usually, each end-user is assigned a specific task. During the course of this test, the program flow is checked and evaluated to determine if it matches the natural strategy of the user in navigating within the application. Moreover, this test determines which application areas are initially and usually accessed and its user-friendliness as well.

A moderator is often tasked to undertake this quality assurance test. Throughout the process, he does not need to communicate anything to the end-user. Rather, he will only be documenting or recording the reaction of the user towards the application. At the session’s end, he interviews the end-users and endorses their feedback to the software developer. This way, interface testing improves the software’s overall acceptance and the consumer’s user experience. Factors like functionality, performance speed, the time needed to use the program, the ease with which the user remembers using the program, user satisfaction, and the rate of user errors are the usual criteria that developers have for a well-designed user interface.

Other software testing types aside from interface testing include component testing, system testing, acceptance testing, and release testing. Component testing requires testing all individual components of software design. System testing, on the other hand, involves testing the functional and non-functional requirements of application systems. Acceptance testing evaluates and compares the system against pre-set requirements. Lastly, release testing is conducted to determine if a new system is compatible to the current technical environment.
