How does social network work?

C. Read the text and answer the questions that follow.

Let's imagine a citizen's ordinary day at work. The morning probably starts with a cup of coffee/tea, followed by greeting the colleagues. Then comes the inevitable, which is log in the computer. For many of us the third step has become an automatic behavior and it dominates the rest of our work day, receiving and sending dozens of emails.
An e-mail is an electronic mail. It is a computer-aided way of exchanging digital text messages from a sender to one or multiple recipient/s. E-mails operate through a network of computers linked by the Internet. There are commercial server agencies such as Yahoo, Gmail, Ymail, Hotmail, etc. that accept the text message from the sender, forward it and deliver instantly to the digital mailbox of the recipient. If the recipient is not online, the message is stored and delivered later when the recipient is online. It works instantly just with the click of your mouse. It has been a powerful communication tool in modern life.
