Studying abroad is not just about earning a degree—it’s also about building a global career. For many international students, the post-study work (PSW) opportunities available in a country are just as important as the quality of education. In 2025, with evolving immigration policies, changing job markets, and the rise of skill-based industries like AI, sustainability, […]
Studying abroad is a dream for many students, and the United Kingdom (UK) consistently ranks among the most sought-after destinations for higher education. Known for its prestigious universities, vibrant culture, and globally recognized degrees, the UK offers international students a unique blend of academic excellence and life-changing opportunities. Whether you’re aiming for undergraduate, postgraduate, or […]
The beam-penetration technique is an early method used for producing colored displays in CRT (Cathode Ray Tube) monitors. It was commonly applied in random-scan (vector scan) CRT systems before modern raster-scan and flat-panel displays became dominant. What is Beam-Penetration Technique? In this method, the screen is coated with multiple layers of phosphor materials (usually two […]
In computer graphics, animation is created by displaying objects in different positions over time. A simple example is a man object moving across the screen using C graphics programming. This program uses the <graphics.h> library to draw a stick figure and simulate walking motion by updating its position step by step. #include <graphics.h> #include <conio.h> […]
A computer system is a combination of hardware, software, and operating mechanisms that work together to execute tasks efficiently. Understanding how a computer system operates is essential for students, IT professionals, and researchers, as it explains the interaction between different components such as the CPU, memory, input/output devices, and operating system. What is Computer-System Operation? […]
In computer graphics, display systems play a crucial role in how images are generated on a screen. Two of the most widely discussed techniques are the Raster Scan System and the Random Scan System. Both approaches are used to display images, but they differ significantly in their working principles, applications, and output quality. Understanding their […]

What is a Liquid Crystal Display (LCD)? A Liquid Crystal Display (LCD) is a flat-panel display technology widely used in electronic devices such as calculators, televisions, laptops, digital watches, and smartphones. It works by using the light-modulating properties of liquid crystals that do not emit light directly but instead use a backlight or reflector to […]
