Laptop is characterized by its compact body. It is a small and portable personal computer that is more convenient to carry than a desktop computer. The current development trend is that the volume is getting smaller, the weight is getting lighter, and the functionality is getting stronger. In order to reduce size, laptops use liquid crystal displays (LCD screens). In addition to the keyboard, there is also a Touchpad or Pointing stick installed as a pointing device. The difference between laptops and desktops lies in portability, which has different requirements for the capacity of the motherboard, central processing unit, memory, graphics card, and computer hard drive. Today's laptops are differentiating into different trends based on their usage, with netbooks tending towards daily work and movies; Business models tend to be stable, with lower power consumption and longer battery life; Household laptops have good performance and high cost-effectiveness, while game laptops are specifically designed to cater to a small group of people who go out for gaming; Fever level configuration, good entertainment experience, but of course the price is not low, and the battery life is not ideal.
There are many brands of laptops in the global market. In order (not in order): Apple, Lenovo, HP, ASUS, Acer, etc
