Both VPN and Proxy are used to connect to a remote system where one can access the host system from a remote location. However, VPNs are superior than Proxy servers because a VPN can protect your privacy and security by routing your traffic via a secure VPN server and encrypting it. A Proxy, on the other hand, just routes your traffic via a mediating server and it does not provide any additional security.Read through this article to find out more about VPN and Proxy and how they are different from each other.What is a Virtual Private Network (VPN)?A virtual private ...

Testing is the most important stage in the process of delivery of any software product, as it not only validates the quality of the product but also provides an opportunity to the developer to improve it further. Unit testing and integration testing are both software testing techniques, but they are quite different from each other in their scope and they focus on different parts of the software. Read this article to learn more about unit testing and integration testing and how they are different from each other. What is Unit Testing? Unit testing is a type of testing technique in ...

In general, we can say that both Testing and Checking are used to evaluate a software product to make sure it behaves as expected. Both these processes are performed before the delivery of the product to ensure the delivery of correct and genuine product. Read this article to learn more about Testing and Checking and how they are different from each other. What is Testing? Testing is defined as a process of validating a product along with learning about that product by investigating and exploring the product during the process. Thus, testing is the process that motivate the tester to ... Read More

Data plays a crucial role in understanding the business trends. Many organizations generate and process huge volumes of data. This huge and complex data is referred to as "Big Data". Big data is of three types: structured data, semi structured data, and unstructured data. What is Structured Data? Structured data is generally stored in tables in the form of rows and columns. Structured data in these tables can form relations with another tables. Humans and machines can easily retrieve information from structured data. This data is meaningful and is used to develop data models. Structured data is used by ... Read More

In C, we have containers to hold data of same data type as well as different data types. C provides the concept of Arrays to store data variables of same type; while for storing data of different types, C has the concept of structures and unions. Both Structures and Unions can hold different types of data, but on the basis of their internal implementation, we can find several differences in both of these containers. Read this article to learn more about structures and unions and how they are different from each other. What is Structure in C Program? In C ... Read More

When we surf the Internet, a two-way communication takes place between our web browser (client) and a web server (server). To regulate this communication, there are some protocols among which the most common one is the HTTP protocol, where the browser sends an HTTP request to the server and then the server returns an HTTP response to the browser.On the basis of the type of response sent to the browser, we can classify the webpages into two categories: Static webpage and Dynamic webpage.Read through this article to find out more static and dynamic webpages and how they are different from ...

Primarily, there are two types of data types − Primitive and Non-primitive. Primitive data types are predefined types of data, which are supported by the programming language. Non-primitive data types are not defined by the programming language, but are instead created by the programmer. With this brief introduction to data types, let's start this article and differentiate Stack and Queue data structures. Both Stack and Queue are types of data structures to store data in a particular order. A stack data structure is a type of linear list which allows the insertion or deletion of an element ...

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

Multitasking plays an important role in the context of defining the performance of a computer. Multitasking decides how processes are divided and performed by the CPU between different inputoutput subsystems. In order to process multiple tasks most efficiently, computer systems use various methods to schedule the tasks, speed up calculations and improve Web browsing among which Spooling and buffering are the primary methods. In this article, we will discuss the major differences between spooling and buffering. But before going into the differences, let's have a basic overview of spooling and buffering so that it will become easier to understand how ... Read More

Artificial Intelligence and Machine Learning play an important role in anything that is remotely related to Automation. AI and ML are the most advanced and popular technologies used for creating intelligent systems in different fields of engineering and science. Although AI and ML are correlated, they are quite different from each other. AI is a wider concept that is used to build intelligent machines for the simulation of human thinking capability and behavior, whereas ML is an application of AI that allows machines to learn from data without being programmed explicitly. Read this tutorial to find out more about AI and ML and ... Read More
