The most basic difference between the waterfall model and the RAD model is that the waterfall model is a linearly-sequential life cycle model of software development in which software testing is done after the completion of all coding phases. On the other hand, RAD (Rapid Application Development) is an incremental model of software development. Read through this article to find out more about the waterfall model and the RAD model and how they are different from each other. What is Waterfall Model? Waterfall Model is the classical model of software development where each phase of software development is completed in ... Read More
There are various application programs that we can use to access the resources of a remote machine. Telnet and SSH are the primary client server application programs that use remote terminal service which allows a user at one site to interact with a remote timesharing system at another site as if the user’s keyboard and a display is connected directly to the remote machine. Telnet and SSH both are Layer7 application layer protocols and both use TCP (Transmission Control Protocol) at the transport layer. In this article, we will discuss the important differences between SSH and Telnet. But before going ... Read More
Both spear phishing and whaling are types of cyberattacks. Spear phishing is a type of phishing attack in which scammers install malware on the targeted user’s system in addition to stealing data for fraudulent objectives, whereas whaling is a cyberattack on high profile persons such as CEOs, CFOs, celebrities, politicians, etc. Whaling is a relatively highrisk strategy as compared to spear phishing. Read through this article to find out more about spear phishing and whaling and how they are different from each other. What is Spear Phishing? Spear Phishing is a type of email phishing attack where a personalized email ... Read More
Software testing involves only the testing of software parts of the system, while embedded testing involves the testing of both software and hardware parts of the system. Read through this article to find out more about software testing and embedded testing and how they are different from each other. What is Software Testing? Software testing refers to verifying and validating the behavior of the software developed. It ensures that software works as expected without any defect. It also helps in documenting that software is meeting the requirements and is ready to use. Software testing also checks the exceptions and error ... Read More
There are two types of computing methods namely, soft computing and hard computing. The basic difference between the two is that the hard computing is a conventional computing method which relies on the principles of certainty, accuracy, and inflexibility, on the other hand, the soft computing is a modern methodology that relies on the principles of approximation, flexibility, and uncertainty. In this article, we will discuss the important differences between soft computing and hard computing. But, before going into the differences, let's start with a basic overview. What is Soft Computing? Soft Computing is a modern computing model that ... Read More
SDRAM and DDR are two different types of RAM. SDRAM was released in 1993 and the latest variant of SDRAM are DDR1, DDR2 and DDR3. SDRAM stands for Synchronous Dynamic Random Access Memory. SDRAM was very common before the release of DDR. SDRAM is a single data rate memory. On the other hand, DDR stands for Double Data Rate. As the name indicates, DDR provides double data transmission in each clock cycle as compared to SDRAM. Read through this article to find out more about SDRAM and DDR and how they are different from each other. What is SDRAM? SDRAM ... Read More
Raster scan and random scan are two of the most popular approaches used to display the pictures and images of objects on the screen. Raster scan is a technique in which a rectangular pattern of the image is captured on screen, whereas random scan is one in which the picture is constructed through an electron beam. Read through this article to find out more about raster scan and random scan and how they are different from each other. What is Rater Scan? In raster scan, the electron beam is swept across the screen, one row at a time from top ... Read More
The process to alter the structure of a database is basically categorized into two ways, one is Normalization and the other is Denormalization. The basic difference between normalization and denormalization is that the database normalization removes the redundancy of data and anomalies in a poorly designed table, while denormalization combines multiple table data into one so that it can be queried quickly. Read through this article to find out more about normalization and denormalization and how they are different from each other. What is Normalization? Normalization is used to remove redundant data from the database and to store non-redundant and ... Read More
In this tutorial, you will learn about JavaScript decorators and get to know about their inner workings and uses. What are Decorators in JavaScript? The word decorator means combining a set of code or program with another or can be said as wrapping a function with another function to extends the functionality or working of the function. Decorator can also be called as decorator function. Developers have been using this decorator term in other languages like python, C# and now JavaScript has also introduced the decorator. Function decorators In JavaScript functions behaves like objects so they are also known as ... Read More
In this tutorial, you will learn about JavaScript DOM manipulation using a service worker. DOM manipulation happens is when we change the structure and elements of the document object model(DOM). We can modify DOM by adding, removing, Changing, or modifying elements and their attributes. What is a Service worker? Service workers work like proxy servers between web browsers and the web server. It adds enhancement to the existing websites in case the user’s browser doesn’t support the service worker but he visits any website that uses the service worker then also no function gets affected. It acts between web applications, ... Read More
