What is a socket and how does it relate to the IP address and port?
Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
How do IP addresses and ports work together?
Ports work the same way. You have an IP address, and then many ports on that IP address. When a program on your computer sends or receives data over the Internet it sends that data to an ip address and a specific port on the remote computer, and receives the data on a usually random port on its own computer.
What are ports in IP address?
IP Address vs Port Number –
| IP ADDRESS | PORT NUMBER |
|---|---|
| Used to identify a host | Used to identify an application/services on your system |
| An IP address is the address of the layer-3 IP protocol. | A port number is a layer-4 address used by some layer-4 protocols e.g. TCP and UDP |
What is the difference between IP and port?
IP address is address of the system in the Network. Port is address of the service within the System. So IP address + Port defines address of the particular service on the particular system.
What is the difference between a port and a socket quizlet?
TCP and UDP ports ensure that data is transmitted to the correct process among multiple processes running on the computer. A socket consists of both a host’s IP address and a process’s TCP or UDP port, with a colon separating the two values. For example, the standard port for the Telnet sevice is TCP 23.
What is Port networking?
In computer networking, a port is a communication endpoint. It completes the destination or origination network address of a message. Specific port numbers are reserved to identify specific services so that an arriving packet can be easily forwarded to a running application.
How is an IPv6 address written and displayed quizlet?
IPv6 addresses are written and displayed as follows: *An IPv6 address has 128 bits that are written as eight blocks (also called quartets) of hexadecimal numbers separated by colons, like this: 2001:0000:0B80:0000:0000:00D3:9C5A:00CC. *Each block is 16 bits.
