Task 1 D1

• TCP/IP Transmission Control Protocol (TCP) is the way in which information is sent from one device to another such as Bluetooth and Wi-Fi. Internet Protocol (IP) is the way in which information is transferred over the internet such as email. • HTTP Hypertext Transfer (or Transport) Protocol. The data transfer protocol used to make up the pages on the World Wide Web (internet) • HTTPS Hyper-text transfer protocol secured. It's used for secure connections to websites, such as banking and logging into an account. The S shows that this is a safe site to use and no one can get your bank details from this. If you visit a web site or web page, and look at the address in the web browser, it will likely begin with the following: http://. This means that the web site is talking to your browser using the regular 'unsecured' language. In other if you fill out a form on the web site, someone might see the information you send to that site. But if the web address begins with https://, your computer is talking to the web site in a secure code that no one can eavesdrop on. • SMTP SMTP stands for Simple Mail Transfer Protocol. This is the protocol for sending e-mails between servers; most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another.
