Simply, the client is the computer connects by way of a unique ip address online and also the server is the one other computer connected to the internet that takes proper hosting and serving webpages. Servers aren't but software operating on high speed machines. Higher than normal speed machines are created in terms that they handle the requests of numerous clients. All of the requests are served as well to those who access an e-mail or webpage. This process is known as hosting.
Whenever an email is sent out, the system connects for your email service's mail server the centralized computer that manages a unique service. For example an e-mail server handles emails. This email server which is responsible of sending email is called Simple Mail Transfer Protocol (SMTP) server. The SMTP server passes the mail to a different SMTP server for the destination through several hops. Every email has got the sender's and recipient's address. When an email is transmitted, the consumer connects on the SMTP server of the sender's email service. The address with the sender, recipient along with the content of the message is transmitted through the client.
