What range of ports can either be used by TCP or UDP to identify the requested service on the destination device or as a client source port select one?
Between the protocols User Datagram Protocol (UDP) and Transmission Control Protocol (TCP), there are 65,535 ports available for communication between devices.
What is the port number of TCP?
65,535 ports
A port is a 16-bit unsigned integer, and the total number of ports available in the TCP/IP model is 65,535 ports. Therefore, the range of port numbers is 0 to 65535. In the case of TCP, the zero-port number is reserved and cannot be used, whereas, in UDP, the zero port is not available.
What is the complete range of TCP and UDP well known ports quizlet?
* There are three ranges of TCP and UDP ports. The well-know range of port numbers is from 0 – 1023.
Which TCP header field specifies the number of bytes that can be accepted before an acknowledgement is required?
The window size specifies the amount of data that can be sent before an acknowledgment is received from the receiver. This value specifies the highest number of bytes, not the required number of bytes.
What is the complete range of TCP and UDP ports?
Explanation: There are three ranges of TCP and UDP ports. The well-know range of port numbers is from 0 – 1023.
What ports use UDP?
Table 1 Common TCP/IP Protocols and Ports
| Protocol | TCP/UDP | Port Number |
|---|---|---|
| Domain Name System (DNS) (RFC 1034-1035) | TCP/UDP | 53 |
| Dynamic Host Configuration Protocol (DHCP) (RFC 2131) | UDP | 67/68 |
| Trivial File Transfer Protocol (TFTP) (RFC 1350) | UDP | 69 |
| Hypertext Transfer Protocol (HTTP) (RFC 2616) | TCP | 80 |
What is the port range?
0 to 65535
Port numbers range from 0 to 65535, but only port numbers 0 to 1023 are reserved for privileged services and designated as well-known ports.
What are TCP ports used for?
Ports are numbered and used as global standards to identify specific processes or types of network services. Much like before shipping something to a foreign country, you’d agree where you’d be shipping out of and where you’d have it arriving, TCP ports allow for standardized communication between devices.
At which layer UDP is most likely to be used?
UDP operates at Layer 4. UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.
Which of the following is used to identify a UDP socket?
UDP sockets are not identified by the remote address, but only by the local address, although each message has an associated remote address that can be retrieved from each datagram with the networking application programming interface (API).

How are port numbers used in the TCP IP encapsulation process?
Source port and destination port numbers are randomly generated. If multiple conversations occur that are using the same service, the source port number is used to track the separate conversations.
How many ports are there in TCP?
All TCP traffic needs one destination port and one source port to establish a connection. At the point when a client needs to speak with a server, client will be appointed an ephemeral port to be utilized for simply that one connection, while server tunes in on a static system framework or registered port.
What are the TCP source and destination port numbers?
This section contains one of the most well-known fields in the TCP header, the Source and Destination port numbers. These fields are used to specify the application or services offered on local or remote hosts. We explain the importance and functionality of the TCP source and destination ports, alongside with plenty of examples.
What are the different types of ports in networking?
On most operating systems, any client of any entry-level can run a program tuning in on a Registered port. Lastly, there is a range of ports from port 49152-65535. These are known as Ephemeral ports (or private ports). Ephemeral ports can’t be enlisted with IANA and are commonly utilized for setting up outbound network traffic and connections.
What is the purpose of the source port?
The source port serves analogues to the destination port, but is used by the sending host to help keep track of new incoming connections and existing data streams. As most of you are well aware, in TCP/UDP data communications, a host will always provide a destination and source port number.
