Golang is a powerful programming language that offers various loop structures for iteration, including the traditional for loop and the foreach loop. These loops are essential tools in any programmer's toolbox, and they help to simplify repetitive tasks. In this article, we will discuss how to use for and foreach loops in Golang and provide some practical examples. Understanding the For Loop in Golang The for loop is one of the most commonly used loop structures in Golang. It is used for iterating over a range of values, such as an array or a slice. The basic syntax of the ... Read More
Ellipsis (...) is a special syntax in Golang that allows developers to pass a variable number of arguments to a function. This can be extremely useful when working with functions that require a variable number of arguments, such as print statements or string concatenation. In this article, we will discuss how to use ellipsis in Golang and provide some practical examples. Understanding Ellipsis in Golang Ellipsis (...) is a syntax that allows developers to pass a variable number of arguments to a function. This syntax is used in the function signature and indicates that the function can take any number ... Read More
Arrays are an essential data structure in programming. They allow us to store a fixed-size sequence of elements of the same type. In Golang, arrays can be sorted in ascending or descending order based on the type of data they contain. In this article, we will discuss how to use array reverse sort functions for integers and strings in Golang. Sorting an Array of Integers in Descending Order To sort an array of integers in descending order, we can use the "sort" package that comes with Golang. The "sort" package provides the "IntSlice" type, which is a wrapper around a ... Read More
A system of components that is used to provide the desired response by controlling different parameters in the process is referred to as a control system. In a control system, the final output or response of the system is controlled by varying the input, and hence it named so. Based on the control mechanism used, the control systems can be classified into the two types namely, feedback control system and feed forward control system. The fundamental difference between the feedback control system and feed forward control system is that in the case of feedback control system, the corrective action is ... Read More
In some cases, it might be necessary to reduce the size of a file by removing the data at the end of it. This process is called truncation. In Golang, truncating a file can be accomplished using the Truncate method provided by the os package. This method changes the size of the file to the specified length, effectively removing any data beyond that point. In this article, we will discuss how to truncate a file in Golang. Truncating a File in Golang To truncate a file in Golang, you need to perform the following steps − Open the file ... Read More
There are two popular display technologies namely, E-Paper and LCD. The fundamental difference between E-Paper and LCD is in their display image technology that is, the e-paper uses e-ink (electronic-ink) technology to display images, while the LCD (Liquid Crystal Display) uses liquid crystals technology to display images. In this article, we will discuss the important differences between E-paper and LCD. But before that let us first know a bit about them individually. What is E-Paper? E-Paper stands for Electronic Paper. E-paper is a display technology that displays images on a screen in the same look and functionality of the ... Read More
There are two types of digital video interfaces namely, DVI (Digital Visual Interface) and HDMI (High-Definition Multimedia Interface) that are used for transmitting digital video signals from source devices to a display device like TV, monitor, projector, etc. The most fundamental difference between DVI and HDMI is that DVI (Digital Visual Interface) can transmit only video signals, while HDMI (High-Definition Multimedia Interface) can transmit both video and audio signals. In this article, we will discuss all the important differences between DVI and HDMI interfaces. But before that let us first discuss a bit about DVI and HDMI individually. What ... Read More
An electronic device that is used for capturing digital images and videos is referred to as a digital camera. A digital camera typically consists of a sensor based mechanism to capture the light and transform it into digital form. Several types of digital cameras are available in market such as DSLR cameras, mirrorless cameras, and compact point and shoot cameras, etc. In this article, we will discuss the important differences between DSLR and mirrorless cameras. But before discussing the differences, let us first discuss the basics of DSLR and mirrorless cameras individually. What is a DSLR Camera? DSLR, Digital ... Read More
There are two different modes of addressing namely, Direct Addressing Mode and Implied Addressing Mode, to address operands in computer programs. Therefore, the fundamental difference between direct and implied addressing modes is in their method of specifying operands in computer programming. Before discussing the differences between direct and implied addressing modes, let us first know a bit about them individually. What is Direct Addressing Mode? In computer programming, the addressing mode in which the actual memory address of the data is given to specify the operand is termed as direct addressing mode. Therefore, in the case of direct addressing mode, ... Read More
DDR stands for Double Data Rate. It is a version of RAM (Random Access Memory). The DDR RAM is capable of transferring data on both edges, i.e. falling edge and rising edge of the clock pulse. Thus, it doubles the data transfer rate, hence it named so. The DDR RAM also comes in several versions (or generations), such as DDR, DDR2, DDR3, DDR4, and DDR5. Each version/generation of the DDR RAM offers enhanced performance in terms of speed, storage capacity, energy efficiency, etc. In this article, we will discuss the two generations, i.e. DDR3 and DDR5 of the DDR RAM, ...
