Python is a popular programming language that is widely used for data analysis and scientific computing. It provides a vast range of libraries and tools that make data manipulation and analysis simpler and faster. One such library is Pandas, which is built on top of NumPy and provides easy−to−use data structures and data analysis tools for Python. In this tutorial, we will explore how to count the number of lines in a CSV file using Python and the Pandas library. Counting the number of lines in a CSV file is a common operation that is required in data analysis and ... Read More
In computer organization, a computer instruction is a set of commands that tells the computer hardware to perform a specific operation. Therefore, computer instructions are the primary building blocks of a computer program and hence a software, because computer instructions are entirely responsible for execution of the program or software. In this article, we will learn the basic computer instructions in computer organization. The format in which the computer instructions are to be written is defined by the instruction set architecture (ISA) of the computer. The instruction set architecture defines the set of instructions that are supported by the processor ... Read More
In electronic devices like computers, laptops, and more, power supplies are one of the most important components. Power supplies are essential for efficient and reliable functioning of the electronic devices. In most electronic devices, two types of power supplies are very common namely, SMPS (Switch Mode Power Supply) and LPS (Linear Power Supply). The primary function of both SMPS and linear power supply is the same, i.e. to convert a high voltage AC supply in a low voltage DC supply using an assembly of transformer and rectifier. But they are completely different from each other. The fundamental difference between SMPS ... Read More
In the field of electrical and electronics, a stabilizer is an electronic device that is employed for regulation and stabilization of voltage supplied to the connected load devices. The primary function of a stabilizer is to provide a constant and steady voltage to the connected devices; hence it is also known as voltage stabilizer. As we know, we receive fluctuating voltages many times from our main power grid. These fluctuating voltages can damage sensitive electronic devices like laptops, computers, TVs, and other appliances. Hence, we need to provide a stable voltage to protect all these devices. For this purpose, a ... Read More
LCD (Liquid Crystal Displays) are used in a variety of electronic devices like TVs, computer monitors, digital watches, multi meters, automobile appliances, etc. LCD displays generally come with two different types of display panels namely, Vertical Alignment (VA) Panel and In-Phase Switching (IPS) Panels. In this article, we will explore all the major differences between IPS panel and VA panel. But before that let’s have a look into the basics of IPS panel and VA panel individually. What is IPS Panel? In context of display panels, IPS stands for In-Phase Switching. IPS panel is a type of display panel used ... Read More
Bluetooth is a technology used for data transfer between electronic devices wirelessly. It is a short distance data communication medium, allowing exchange of data and information without the need of cables. Bluetooth technology uses radio waves for wireless data communication. It follows the master-slave architecture, i.e. one device works as a master device (sender) and another device works as a slave device (receiver). Today, Bluetooth technology is being used in a wide range of applications like data transfer, audio streaming over speakers, headphones, etc., hands free calling, connecting peripherals like mouse, keyboard, etc. Bluetooth technology has evolved over the time, ...

Analyzing the frequency of unique values within a NumPy array is a common task in data analysis. It provides valuable insights into the distribution and occurrence of elements, enabling effective data exploration and preprocessing. In this article, we will explore various methods to count the frequency of unique values in NumPy arrays. By leveraging built−in NumPy functions and external libraries such as pandas and collections, we will guide you through step−by−step implementations of these techniques. Through this comprehensive guide, you will gain the necessary knowledge to accurately analyze and extract meaningful information from your NumPy arrays. Method 1: Using the ... Read More
Python has become one of the most popular programming languages for data analysis and manipulation, thanks to its rich libraries and frameworks. Among these libraries, Pandas stands out as one of the most valuable and powerful tools for data processing. With Pandas, you can easily load, transform, and analyze data in a wide variety of formats. In this tutorial, we will explore converting a wide data frame to a tidy data frame using the Pandas stack() function. Converting a wide data frame to a tidy one is an essential step in many data analysis workflows, as it allows for easier ... Read More
Introduction Many companies have been in the market for only 2 to 3 decades, however they are giants that are beyond competition. This superior power is given to them by our digital infrastructure. These are the start-ups or companies that were able to understand how data and the digital world are going to change the future. Data and digital technology have not only changed the business world but have entirely revolutionized the lives of customers. Companies that can adapt themselves in time as per the needs of the customer and the technology are the superpowers of today. Netflix is one ... Read More
Introduction Data is the fuel that keeps businesses running today. Technology helps businesses capture umpteen amounts of data every minute via satellite, smartphones, television, and other necessary devices for today’s survival. All this data that businesses are capturing today has a story to tell. Machine learning and artificial intelligence help businesses find the points of similarities and dissimilarities in the data and its patterns; now it is in the hands of humans to read the data. Create stories that this data wants to tell and convey to fellow humans so that businesses can make use of the data and its ... Read More
