In the study of statistics and data-analysis, normal distribution or Gaussian Distribution is a widely used probability distribution. It is a bell-shaped curve that characterizes the probability and is often used to model real-world phenomena. We use the random module available in Python’s Numpy library to generate random numbers from the normal distribution. It also allows users to generate random numbers from the normal distribution with a specified mean and standard deviation. Syntax numpy.random.normal(loc=0.0, scale=1.0, size=None) Parameters loc (float or array_like): It is the mean or centre of the distribution. The default value is 0.0 ... Read More
Chebyshev series is a polynomial series referring to a series of Chebyshev Polynomials. A Chebyshev Polynomial is a Polynomial that is defined in a specific interval which is orthogonal in nature. It has a weight function $\mathrm{(1-x^{2})^{(-½)}}$. This polynomial is named after the Russian mathematician, Pafnuty Chebyshev. Orthogonality is a specific type of relationship that defines two polynomials. Two polynomials are orthogonal in nature if their relationship satisfies certain conditions. For example, two functions can be considered orthogonal if their integration over a certain interval equates to 0. Chebyshev Polynomials are defined as \mathTn(x). They are defined recursively ...

RPC and SOAP are two methods for implementing remote procedure calls between distributed systems. SOAP is a protocol that encodes messages in XML and transports them through HTTP or HTTPS. Remote Procedure Call (RPC) is a protocol that allows a client application to call a remote server's method or function as if it were a local function call. Read this article to find out more about RPC and SOAP and how they are different from each other. What is RPC? Remote Procedure Call (RPC) is a protocol that allows a client application to call a remote server's method or function ... Read More
An operating system (OS) is a system software that manages the computer hardware and software, and it provides services and functionality to programs and users. A real-time operating system (RTOS) is a segment of an operating system that is designed to provide predictable and deterministic behavior for time-critical applications. While RTOS and general-purpose OS have certain similarities, they also have some major differences. Read this article to find out more about RTOS and OS and how they are different from each other. What is a Real-Time Operating System? A real-time operating system (RTOS) is a type of operating system that ... Read More
Coaxial cables such as RG6 and RG11 are used for transmitting high-frequency signals over long distances. The two cables' principal differences are their sizes, the level of signal loss they go through over a given distance, and their maximum bandwidth. RG6 and RG11 coaxial cables are both used for transmitting high-frequency signals, with RG11 being larger and more resilient than RG6 and having reduced signal loss over long distances. Read this article to find out more about RG6 and RG11 and how they are different from each other. What is RG6? RG6 is a type of coaxial cable used for ... Read More
Intranet and Portal are both used within organizations to help organize and share information, but they differ significantly. An Intranet is a private network that only employees within a company can access. A Portal is a web-based platform that allows access to numerous types of information and services. Read this article to find out more about Intranet and Portal and how they are different from each other. What is Intranet? An intranet is a private network that allows employees within a company to share information and resources. It is an efficient and secure way to facilitate internal communication and cooperation, ...

PPTP (Point-to-Point Tunneling Protocol) and L2TP (Layer 2 Tunneling Protocol) are two VPN protocols that are used to establish secure and private internet connections. While both protocols accomplish the same objective, they differ significantly in terms of security, compatibility, and speed. L2TP is a more modern and safe protocol that uses stronger encryption methods and is more vulnerable to attacks. PPTP is a VPN protocol developed by Microsoft that is commonly used for establishing secure and private internet connections. Read this article to find out more about PPTP and L2TP and how they are different from each other. What is PPTP? ... Read More
The two types of statistical tests used in hypothesis testing are paired and unpaired tests. The main difference between them is how data is collected and compared. A paired test compares two sets of measurements that are connected or related in some way. An unpaired test involves comparing two sets of measures that are not related or connected in any way. Read this article to find out more about Paired Test and Unpaired Test and how they are different from each other. What is Paired Test? A paired test is a statistical test that compares two sets of measurements that are ... Read More
NTFS and sharing permissions are two types of access control mechanisms used in Microsoft Windows operating systems to regulate file and folder access. NTFS permissions are applied to files and directories on an NTFS-formatted volume. Share permissions are applied to shared folders and regulate network access to the shared folders. Read this article to find out more about NTFS and Share Permissions and how they are different from each other. What is NTFS? Microsoft Windows operating systems use the NTFS (New Technology File System) file system to manage and store files on hard drives, solid-state drives (SSDs), and other storage devices. ... Read More
Microsoft FrontPage and Adobe Dreamweaver are popular web development programmes used by web developers and designers to create and maintain websites. However, there are significant differences between the two in terms of features, functionality, and convenience of use. Dreamweaver is more advanced and adaptable, making it more suited for professional web developers that require more control over their websites. FrontPage, on the other hand, is better suited for beginners and non-technical users who want to quickly and simply develop simple websites. Read this article to find out more about Microsoft FrontPage and Adobe Dreamweaver and how they are different from ... Read More
