Question

Carol is browsing the Web. Which of the following ports is she probably using?

a) Port 80 (HTTP)
b) Port 22 (SSH)
c) Port 443 (HTTPS)
d) Port 25 (SMTP)

Answer 1

Carol is most likely using Port 80 (HTTP) while browsing the web.

Step-by-step explanation:

Carol is most likely using Port 80 (HTTP) while browsing the web. This is the default port for Hypertext Transfer Protocol (HTTP), which is the protocol used to transmit data on the World Wide Web. It allows Carol to view web pages, access websites, and download files.

Port 22 (SSH) is typically used for secure remote login and secure file transfers, so it is not relevant to Carol's web browsing activity.

Port 443 (HTTPS) is used for secure web browsing. It is commonly used when websites need to transmit sensitive information, such as passwords or payment details. While Carol may use this port if she is accessing a website with HTTPS (secure) protocol, Port 80 is more common for general web browsing.

Port 25 (SMTP) is used for sending email messages. It is not directly related to web browsing, so it is unlikely that Carol is using this port while browsing the web.
