Both the Spiral Model and the Waterfall Model are widely used development methodologies in the software industry. Both of these models are practices for better tracking and have application development in systematic way. The basic difference between spiral model and waterfall model is that the spiral model works in evolutionary method and generally used by developers, whereas the waterfall model works in a sequential method and generally used by customers. In this article, we will discuss the important differences between spiral model and waterfall model. But before going into the differences, let's start with some basics of these two ... Read More
Both multiprocessing and multithreading are used in computer operating systems to increase its computing power. The fundamental difference between multiprocessing and multithreading is that multiprocessing makes the use of two or more CPUs to increase the computing power of the system, while multithreading creates multiple threads of a process to be executed in a parallel fashion to increase the throughput of the system. In this article, we will discuss all the important differences between multiprocessing and multithreading. Let's start with some basics of multiprocessing and multithreading so that it becomes easier to understand how they are different from each ... Read More
Both multiprogramming and multitasking are the concepts related to the operating systems of computer. It is not a good practice that keeping the CPU occupied for a single task only. Since, there is a considerable difference between the speeds of the CPU and other components of the computer system. This difference increases the CPU idle time and degrades its throughput. Therefore, to overcome this problem, several concepts such as multiprogramming, multitasking, multithreading, etc. have been developed to improve the CPU utilization. In this article, we will discuss the important differences between multiprogramming and multitasking. Let's start with some basics ... Read More
In computer parlance, security and protection are the two terms that seem similar at first glance. Therefore, most people use them interchangeably, but both are quite different from each other. In this article, we will highlight how "security" is different from "protection". Basically, the measures to prevent the interference with use of local and physical resources of computer systems provided by the operating system are known as security and protection. One major difference between security and protection is that security deals with the external threats on the information, while protection handles the internal threats on the information. Before going ... Read More
Both multitasking and multithreading are the concepts related to the operating system of the computer. One major difference between multitasking and multithreading is that multitasking allows the CPU of computer to perform multiple tasks simultaneously, while multithreading allows the CPU to execute multiple threads of the same process simultaneously. Read through this article to find out more about Multitasking and Multithreading and how they are different from each other. Let's start with some basics first. What is Multitasking? When a single CPU is allowed to execute multiple tasks at the same time, it is called the multitasking. In ... Read More
Both WAV and MP3 are the file formats used for defining and storing digital audio files, but they are different from each other. One major difference between WAV and MP3 is that MP3 files are compressed and small sized audio files in which some of the information from the original audio source is removed, whereas WAV files are uncompressed audio files having a file size very much higher than an MP3 file. Read through this article to find out more about WAV and MP3 files and how they are different from each other. What is WAV? WAV stands for Waveform ... Read More
Verification is the process of verifying something to ensure its correctness, while Validation is the process of validating something in which the user tests the system with some inputs and verifies whether the output is as per the expectation or not. In software testing, both Validation and Verification are the parts of the V-model in which the development and testing activities are started based on the requirement of document specification. In other words, we can say that Verification is the process to ensure whether the product that is developed is right or not. It verifies whether the developed product fulfils ... Read More
Each organization has to embrace change to grow, irrespective of its size and nature. These changes can be the requested ones or the unplanned and unexpected changes, like changes in customer trends. Whatever the change is, the manager has to work with the team and the supervisors to address and analyze them before implementing them in the organization. The team carefully evaluates the effects of the change on the company, its long−term objectives, employees, and other resources. Based on this, the change is either accepted or rejected. In this post, we will discuss all that you need to know about ... Read More
