Notebook computers are usually ranging in screen size of 12″ – 17″. Some machines might have a powerful graphics processor, but many are designed to be efficiently light, and compact. In order for notebook PCs to comply with standards, they must have at least 2 USB-C4 ports, and an SD card reader. Those that don’t won’t qualify for education, or government purchases. Many notebooks also have an audio jack which will allow you to plug in speakers for a better sound experience.
