If a network address is thought of as a physical address for a building then a port would be a room within the building. THe function of a port is to allow software to listen for or send out communication that is specifically related to it's function. For example, most internet (http) traffic is on port 80, FTP (File Transfer Protocol) sends and listens on Port 21, other services use other ports. This allows a single computer with a single IP address to be both a web server and a file server.

Which two statement s accurately describe the use of destibation port numbers by clients on a network?
duck?
Which two statement accurately descibe the use of destination port numbers by client on a network?
A port number is linked to an IP address to create a unique identification number for each process being run by a client. Port numbers do not have to be unique, but IP addresses do.
Which mechanisms is most often used in firewall rules to allow traffic on to the network?
Port Numbers
What protocol uses port numbers 67 and 68?
The protocol that uses port numbers 67 and 68 is the Dynamic Host Configuration Protocol (DHCP). Port 67 is used by the DHCP server to receive client requests, while port 68 is used by the DHCP client to receive responses from the server. This protocol is essential for dynamically assigning IP addresses and other network configuration parameters to devices on a network.
Which statements describe the use of destination port numbers by clients on a network?
These can be used in order to check which connections are active. It is possible to create a socket by using a known port number.
What are the two basic port numbers?
ephemeral port numbers and well known port numbers
Which solution when deployed on a network looks for policy matches via the use of IP addresses and port numbers?
proxy firewall
What is a port number in ping?
In the context of using the ping command, the term "port number" is not applicable. Ping operates at the Internet Control Message Protocol (ICMP) level, which does not involve port numbers, as it is primarily used to test the reachability of a host on a network. Instead, ping sends echo request packets and listens for echo replies. Port numbers are relevant for TCP and UDP protocols, which are used for communication between applications over a network.
What are the two basic types of port numbers?
Ephemeral port numbers and well-known port numbers.
What port opens when a PC on the network initiates communication through another port?
Port Triggering opens a port when a PC on the network initiates communication through another port.
Why do you need a port numbers?
Port numbers are essential for identifying specific processes or services running on a device within a network. They allow multiple applications to use network resources simultaneously without interference, as each application can communicate over a distinct port. This system enables proper routing of data packets to the correct service, facilitating effective communication and resource management in computer networks.
What does TCP use to keep track of different conversations crossing a network at the same time between the same hosts?
Port numbers
