How to Find Installation Software for your Hardware

admin — Sat, 24 Jul 2010 15:49:27 +0000

When you wish to add hardware to other hardware, then you often need to have software that will perform the task of synchronizing the two devices together. Examples of hardware you may wish to install include a printer to your home computer, a keyboard to your home computer and other devices which have a physical presence. Hardware means something which is tangible, even although its purpose may be intangible, while software is something which runs on hardware – such as computer programs, online games and more.

In the case of consumer software it is usually the case that installation hardware will come along with the product, meaning you will not have to look any further than the box you got the hardware with to find the installation software. In other instances finding installation software can be harder, especially when you are looking to install the hardware on a different device from which the software development company prepared for. Installation software for printer hardware can often be pre installed on your computer, server or other device when you buy it. On a windows personal computer for example you can find an option to install hardware through accessing the control panel. It is probably worth checking out if this will work before opting to buy or find free installation software from a specific provider. If you have another type of operating system then you should also browse through options and the user manual to find out if this is a possibility that you can exploit.

If you are unsure of the software that you will need in order to install printer driver then you should look inside the user manual and find out if there is an explanation of how you would install that hardware on your machine. If there is no explanation, or advice as to which driver download you will need, then you will need to consult a computer engineer for advice on how to approach this problem, however before you do that it is best to check out if there are any online resources that could help you with this. If you do a search for install “software name” on “hardware name” then you may just find that someone already has the solution there for you. It is also worthy of note that you should try variations of this search query to find out if you can yield any relevant results.

Once you have identified the software you need, either through the internet or otherwise, it is now time to locate and purchase the necessary software. A great tool through which to find and compare software is a shopping comparison engine such as Google Product Search or shopping.com. Type in the name of the software and they will likely provide results of a variety of providers that all offer the software, allowing you to pick the merchant that offers the best price. If you are uncomfortable about completing a purchase online then another great option is going to a local computer software supplier, who may just have exactly what you are looking for.

Classification Among Software Testing

Before delving on various types of Testing, let us firstly understand the basic definitions of Software Testing

Definition of Testing: Software Testing carries many definitions as explained by various practitioners.

Definition – 1:Testing is a process in which the defects are identified, isolated (separated), subjected (sending) for rectification and ensured that the product is defect free in order to produce a quality product in the end and hence customer satisfaction.

Definition – 2:

Definition – 3:

Definition – 4:

Definition – 5:

(A) Methodologies wise there are two ways of Software Testing.

1) Manual Testing:

is a process in which all the phases of Software Testing Life Cycle like Test Planning, Test Development, Test Execution, Result Analysis, Bug Tracking and Reporting are accomplished till successful completion by manual means i.e. with human efforts.

There are few drawbacks of Manual Testing:

such as

# More people are required.

# It is more time consuming.

# It renders less accuracy.

# It is strenuous.

# Simultaneous actions are difficult.

# Repetitive tasks are difficult to perform.

1) Manual testing & 2) Automated testing

2) Automation Testing:

is a process in which majority of drawbacks of manual testing gets addressed properly and it provides speed and accuracy to the existing testing phase.

It must be remembered that automation testing is not a replacement for manual testing. It is in fact a continuation of manual testing aimed to provide speed and accuracy to the testing effort.

Automated testing primarily uses an automation tool, which is assistance to the test engineers. An automation tool works on the basis of instructions and information. Automated tools are broadly of three Types like 1) Functional Tools (like HP quickest, IBM RFT) 2) Management Tools (Like HP Quality Center) 3) Performance Tools (Like HP Load Runner)

There are few drawbacks of Automation Testing: such as

# More expensive.

# We can not automate all the areas.

# Manual testing can not be fully eliminated

(B) Conventionally there are following two types of testing.

1) Unconventional testing & 2) Conventional testing

1) Unconventional Testing:

It is a sort of testing in which quality assurance engineer checks each and every out come document right from the initial phase of the SDLC.

2) Conventional Testing: It is a sort of testing in which the testing engineer tests the application in the testing phase of SDLC.

(C) Levels wise there are following five levels of testing

1) Unit Level Testing:

refers to the testing carried out on small software units. This is a type of white box testing generally performed by the code developers.

2) Module level testing: refers to the testing carried out on a module. This is a type of black box testing generally performed by the test engineers.

3) Integration level Testing: During the process of development, lot many modules are developed along with their respective interfaces, which are used for integrating these modules. While integration the developers check & ensure the perfect working of all such interfaces. This falls under the category of white box testing.

4) System level Testing:

Whatever testing performed on the application after its deployment in its actual environment is termed as system level testing. This falls under the category of black box testing. The testing engineers generally perform system level testing. System level testing generally includes testing like

# System Integration Testing

# Load Testing

# Performance Testing

# Stress Testing

5) User acceptance level testing: It is nothing but a system level testing with the only difference that it is carried out in the presence of the user. It falls under the category of black box testing generally conducted by the Testing engineers.

(D) Techniques wise there are following three types of Testing

1) Black box Testing:

Involves testing of functional part of the application. This is generally conducted by the testing engineers. For conducting black box testing, testers need not have any formal structural knowledge of the code.

2) White box Testing:

This is known as glass box testing or sometimes clear box testing. This involves testing on the structural part of the application. For performing white box testing, in-depth knowledge of the code is essential, hence generally the code developers do this type of testing.

3) Gray box Testing:

Involves testing of functional part as well as the structural part of the application. For performing gray box testing, knowledge of the code is required, hence experienced testers having good knowledge of code development are best suited for performing gray box testing

(E) Intent wise there are following four types of Testing

1) Acceptance Testing

2) Performance Testing

3) Load Testing

4) Regression Testing

Software is the language of a computer. And like human language, there are many different computer languages. Essentially, computer software can be divided into three main groups depending on their use and application. These are system software or operating system referred simply as the OS, application software and programming languages. Usually most of us interact with a computer using application software.

1. System Software: System software or operating system is the software used by the computer to translate inputs from various sources into a language which a machine can understand. Basically, the OS coordinates the different hardware components of a computer. There are many OS in the market. The most popular Os are from the stable of Microsoft. We have all heard, used and wondered at the Windows software, which is an OS. Starting with Windows, Microsoft has migrated to Vista, its latest offering in the market. It may come as a surprise to some that there are other operating systems used by others. Among these UNIX is used for large office setups with extensive networking. XENIX is software which has now become redundant. HP -UX and AIX are some operating systems used by HP computers. Apache OS is quite popular with web servers. IBM still uses proprietary operating systems for its main frames. Proprietary systems are generally built with the help of a variant of UNIX operating system.

2. Application software: A normal user rarely gets to see the operating system or to work with it. But all of us are familiar with application software which we must use to interact with a computer. Popular examples of application software are the Microsoft office suite which includes Word, Excel and PowerPoint. We have used these applications extensively. Internet explorer, Mozilla Firefox is two applications used to access the internet. E-mail software like Outlook express is used to manage Emails. It is obvious that all software utilized for working on a computer is classified as application software. In fact all user interfaces are an application. The anti-virus is an application and so is the Media player.

3. Programming languages: Now this is a kind of computer software which is used exclusively by computer programmers. Unless we are also programmers, we are unlikely to come across programming languages. A simple way to understand programming languages is to think of them as bricks which can be used to create applications and operating system. C++, Java and Simlab are some popular programming languages. Generally Java is used for internet applications. C++ is a language of professional developers and used extensively in developing operating systems. PHP is another language used for internet applications. There is a new class of languages which are being utilized for the mobiles. These are light weight, modular languages which are used to design mobile applications.

Computer software falls under three basic categories; System software or operating system, application software and programming languages. We usually use applications on a day to day basis. These applications are themselves created using programming languages.
