What is a network port and what does it do? Cite your source(s) in APA format
Added by Rafael M.
Step 1
A network port is a virtual point where network connections start and end. It is a numerical identifier in the range of 0 to 65535 that is used by the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) to distinguish different services or Show more…

Every website has a server process listening to TCP port 80 for incoming connections from clients (normally browsers). After a connection has been established the client sends one request and server sends one reply. Then the connection is released. The protocol that defines the legal requests and replies is called (A) TFTP (B) FTP (C) gopher (D) HTTP

Using a theme such as sending an email or transferring a file, you will discuss 20 concepts that allow your data to move from your host to the resource you are requesting and back again. Use your own words and understanding of the concepts to explain the process. If you reference or use a quote to provide clarity to a concept, you must reference your source. This will be prose, not fill in the blank or in list format. This section will consist of the following: a. Minimum of 20 concepts along the "path" of the resource request. Each layer of the TCP/IP model (Chapters 2, 3, 4/5, 6) will have a minimum of five concepts explained (5 x 4 = 20). b. Each step will consist of the following: i. Concept ii. Concept Definition iii. Applicable Port and Protocol iv. Applicable data unit (Data, Segment, Datagram, Frame) v. What this concept provides the user vii. Example: Bob would like to access a webpage at www.example.com. His computer does not currently have an IP address, so his computer creates a DHCP message request. The DHCP server is a network management protocol that dynamically assigns IP addresses to network devices. It uses two ports: 67 for the server and 68 for the client. This message is contained within a UDP segment, which will be encapsulated within an IP datagram. When DHCP provides Bob's computer with an IP address, the computer will be able to communicate with networked resources.

Create a matrix of five common, well-known UDP ports and five common, well-known TCP ports. For each port: [Port #], state the applicable port number (1 port # per row); [Use of Port] in plain English, give a functional description of how the port is used; [Port Service], name the service that runs on that port (usually a short name), [Secure] identify whether it is a secure communication port with a simple Yes or No, [Lab] finally indicate any labs you completed in Week 1 or 2 of this course in which you saw that port (if this port wasn't seen, enter None).
