Note - The first mechanical computer was designed in by Charles Babbage. It was called ' Analytical Engine '. It was the first general-purpose computer. Charles Babbage is known as the father of the computer.
Input The data is entered into the computer with the help of input devices. Like other electronic devices, a computer takes data in raw form binary form. The user can enter the data in several formats such as the collection of letters, numbers, images, etc. The input devices convert the data in the binary form so that the computer can read the data.
It is the internal process where the data is processed according to the instructions given to the computer. The data is executed sequentially and sent for further processing. Suggested Article : Why is my computer so slow? Output The output is the information provided by the computer after the entire processing. It is also known as the result that can be stored in the storage devices for further use.
The output devices retrieve the processed data from the computer and convert the data into a human-readable form. It is used to store data or instructions before and after processing. Generally, storage is divided into the following types: Primary Storage Primary storage devices store the inputted data and immediate calculation results.
The data stored in primary storage is temporary and will be lost if they are disconnected from the power source. Random Access Memory is an example of primary storage. Secondary Storage Secondary storage devices are used to store the data permanently for future use. The data stored in the secondary storage devices is secure even if there is no power supply.
Hard Disk Drive is the widely used secondary storage. At present, the term concludes both the hardware and software. There can be different changes like making the device smaller, cheaper, more smart or powerful, etc. There are five generations of the computer, which are listed below with approximate period: First Generation - Based on - Electronic Valves Vacuum Tubes. Second Generation — Based on - Transistors. Read More : Generations of Computer Uses of Computer As we have discussed above, the computer is the need for the digital era.
Regression testing is useful in all type of testing models. However, it is more successful in Agile testing. It can significantly reduce the testing cost in the long run if applied correctly. It is one of its kind testing approach that aims to build confidence in software going through rapid changes without unintended side-effects. The best way is to choose an automation framework pertaining to your test requirements.
And then create the test suite, start test case automation, and reduce manual testing efforts. To leverage such a test suite, integrate it with CI tools like Jenkins and prepare it to run on the nightly basis.
Regression testing works the best if implemented correctly. It improves the quality of the product under test and has following benefits over traditional methods. Regression testing makes life easier for the testers while working on a large software project. However, it has some limitations which we can overcome with the steps mentioned in the next sections of this tutorial. You already know how critical regression testing is for delivering a quality product. And test cases are the primary elements of a regression test plan that contributes the most to make it successful.
Hence, it is inevitable to select the most appropriate test cases to get the best results. So here are a few ideas for you to ponder. Find out the areas in your product which receive the most bugs and cause to fail with just a small change in the code.
First of all, you can add those defects to regression and then look for increasing the test coverage of that particular area. Online Training. Download Full Source Code. WebDriver Series. About the author. By continuing to browse, you consent to our use of cookies.

Python is an object-oriented programming language created by Guido Rossum in It is ideally designed for rapid prototyping of complex applications.
Moreover, Python is one of the most demanded programming languages in the market, so there are huge job opportunities for candidates having knowledge of Python programming. This Python tutorial is designed for absolute beginners for learning Python online.
However, if you have basic knowledge of any programming language concepts like loops, functions, etc. Python is one of the most popular programming languages.
Currently, each of the following six languages are being used by programmers for developing both desktop and web applications. Skip to content. Python Tutorial Summary In this Python tutorial for beginners, you will learn Python programming basics and advanced concepts.
What is Python Programming Language? Why Learn Python Programming? Programming Languages Difference Between Python and Other Languages Java Python takes less time to develop, although it is expected to run slower than Java programs Due to Python high-level data types and its dynamic typing programs are shorter than Java programs Perl Although both these languages are considered similar in many ways, Perl supports common application-oriented tasks like report generating, file scanning, etc.
RUBY is preferred for Web development and functional programming, while Python is for Academic and scientific programming.
