What is internet dongle?

An internet dongle, also known as a USB modem or data card, is a device that allows users to connect to the internet wirelessly through a mobile network. It is a small, portable device that can be plugged into a USB port on a computer or laptop to connect to the internet. Dongles use 3G or 4G technology to connect to the internet and allow users to access email, browse the web, and stream videos. They are popular for people who travel frequently and need access to the internet on the go or in areas where Wi-Fi is not available. Dongles can be purchased from internet service providers or mobile network providers and usually require a monthly data plan subscription.
