A laptop is a portable computer designed for personal and professional use, offering flexibility with various features. They range in performance from basic tasks like browsing and word processing to high-performance models suitable for gaming, creative work, or programming. Key aspects to consider when choosing a laptop include the processor (CPU), storage capacity, screen size, battery life, and weight. Popular types include ultrabooks (light and thin), gaming laptops (high-performance), and 2-in-1s (convertible designs). Depending on your needs, options vary widely in price and specifications.
