A laptop is a portable computer that combines a screen, keyboard, battery, and hardware in one foldable device. It is used for web browsing, programming, communication, gaming, office work, and more.
The CPU is the brain of the laptop. It processes instructions and runs programs. Faster CPUs make your laptop more responsive.
RAM is short-term memory that stores data the CPU needs right now. More RAM allows more programs and browser tabs to run smoothly.
The GPU handles graphics, video rendering, and games. Some laptops use integrated GPUs, while others have powerful dedicated GPUs.
SSD (Solid State Drive) is fast, quiet, and durable, making it ideal for speed. HDD (Hard Disk Drive) is cheaper with large capacity but slower.
Large CSS files slow down websites, especially on mobile devices. Optimized CSS loads faster and improves user experience.
PHP runs on the server. The faster it processes data, the quicker pages load. This is important for both mobile and desktop users.
Mobile devices need faster, smaller pages because they have slower hardware and networks. CSS should be responsive, and images should be optimized for both screen sizes.
