what is an email? why has email become so widely used?

It is true that Email, which become one of the most ubiquitous platforms, is a way of sending messages and data to other people through computers connected to a network. The first reason is email can be seen as a letter. Email allows people to communicate worldwide, which is more convenient than writing letters. people, for example, can send emails to other people who live in another country, in just a few minutes; therefore, receivers will get a response within minutes. furthermore, email is also a powerful education tool that aids teachers to manage students’ homework assignments. And another reason is in the past we hardly had an email, so we have to use the phone and notes when we want to send messages to other people, this way is quite expensive and time-consuming but in the modern world, we have had an email that is free and needs a computer to access the internet. moreover, it also has a password to enter, so avoids losing letters and private information. In conclusion, Email is a wonderful way to communicate with others. The email has become a very important way to communicate and share files with coworkers, students, friends, and family
