The mains supply in your wall socket delivers AC, while the battery in your phone stores DC. Knowing how each behaves helps you choose the right power source for a project, understand why certain devices need adapters and troubleshoot circuits that aren't working. IJCSEE explains both t…https://ijcsee.org.uk/what-is-the-difference-between-ram-and-rom/https://ijcsee.org.uk/what-is-the-difference-between-ram-and-rom/Sun, 25 Oct 2026 22:34:36 +0000RAM holds the data and instructions your processor is working with right now, while ROM stores the permanent instructions your system needs to start up and run basic functions. The key difference lies in what happens when you turn the power off: RAM loses everything it was holding, but ROM keeps its contents intact. This article walks you through how each type works, where you'll find them in p…https://ijcsee.org.uk/what-does-a-transistor-actually-do/https://ijcsee.org.uk/what-does-a-transistor-actually-do/Sun, 25 Oct 2026 22:33:32 +0000A transistor controls the flow of electricity through a circuit. It can switch current on and off, or amplify a weak signal into a stronger one. These two roles make it the building block of everything from radios to processors, and understanding them shows you how circuits think and respond. IJCSEE breaks down both functions without the jargon.https://ijcsee.org.uk/what-is-the-difference-between-compilers-and-interpreters/https://ijcsee.org.uk/what-is-the-difference-between-compilers-and-interpreters/Sun, 25 Oct 2026 22:32:25 +0000A compiler translates your entire program into machine code before execution begins, while an interpreter reads and executes your source code line by line. The choice between them shapes how quickly you see errors, how fast your program runs and how you distribute your work. IJCSEE breaks down both models so you can recognise which one your language uses and why that matters when you write soft…https://ijcsee.org.uk/what-is-object-oriented-programming/https://ijcsee.org.uk/what-is-object-oriented-programming/Sun, 25 Oct 2026 22:31:33 +0000Object-oriented programming is a way of organising code around objects — self-contained units that bundle related data and the operations that work on that data. Instead of writing procedures that manipulate separate variables, you model your program as a collection of objects that interact. IJCSEE walks you through the thinking behind this approach, the principles that guide it, and where it p…https://ijcsee.org.uk/how-to-tell-if-a-capacitor-is-faulty/https://ijcsee.org.uk/how-to-tell-if-a-capacitor-is-faulty/Sun, 25 Oct 2026 22:30:27 +0000A capacitor that has failed will often show itself through visible damage, unusual circuit behaviour or a measurable change in its electrical properties. You can identify most faults through a combination of visual inspection and simple tests with a multimeter. Below you will find the checks that matter, the order to do them in, and what each result tells you about the component in front of you…https://ijcsee.org.uk/what-is-ohms-law-and-how-do-you-use-it/https://ijcsee.org.uk/what-is-ohms-law-and-how-do-you-use-it/Sun, 25 Oct 2026 22:29:16 +0000Ohm's Law describes the relationship between voltage, current and resistance in an electrical circuit. It states that voltage equals current multiplied by resistance—written as V = I × R—and you use it every time you size a resistor, troubleshoot a short or choose a power supply. IJCSEE explores the principle, shows you how to apply it and explains where it stops working.https://ijcsee.org.uk/what-is-an-algorithm-and-why-does-it-matter/https://ijcsee.org.uk/what-is-an-algorithm-and-why-does-it-matter/Sun, 25 Oct 2026 22:28:34 +0000An algorithm is a step-by-step set of instructions designed to solve a problem or complete a task. You follow algorithms when you assemble furniture from a manual, bake a cake from a recipe or navigate using a map app. In computing, algorithms tell machines how to process data, make decisions and produce results. This guide explains what algorithms are, how they work across different fields, wh…
