Question

Which of the following types of network traffic is an example of TCP protocol traffic?

1) HTTP
2) UDP
3) FTP
4) SMTP

Answer 1

HTTP, FTP, and SMTP are examples of network traffic that use the TCP protocol to ensure reliable transmission of data over networks, whereas UDP represents a different protocol that does not rely on TCP.

Step-by-step explanation:

The Transmission Control Protocol (TCP) is one of the main protocols of the Internet Protocol Suite. TCP is used to ensure the reliable transmission of data between network devices. In the choices provided, the examples of network traffic that use the TCP protocol include:

• HTTP (Hypertext Transfer Protocol) – This protocol is used for transmitting web pages on the internet. When you access a website, your browser uses HTTP over TCP to request web pages from a server.
• FTP (File Transfer Protocol) – This protocol is used for the transfer of files between a client and server on a network. FTP uses TCP to ensure files are transferred reliably.
• SMTP (Simple Mail Transfer Protocol) – This protocol is used for sending emails. SMTP uses TCP to ensure that the emails are reliably delivered to the destination mail server.

In contrast, UDP (User Datagram Protocol) is another transport layer protocol used for establishing low-latency and loss-tolerating connections between applications on the Internet and does not use TCP.
