The purpose of TCP is a connection oriented protocol, meaning that protocol establishes a connection or session between the sources and destination device prior to sending the data segment. UDP is transport layer protocol that provides an interface between the application layer and the network layer.

∙ 14y agoThe port number represents a listening program on a client that will receive that particular packet. The IP address can represent how to route the information, and ultimately the IP address will be compared against the MAC address to deliver the packet to a specific system.
At that point the system has to be aware of what running process or program should receive the packet, since there could be many programs running at the same time.

What are true statements about transport layer protocols?
**The TCP transport layer protocol uses windowing and acknowledgments for reliable transfer of data. **The TCP and UDP port numbers are used by application layer protocols. **The TCP transport layer protocol provides services to direct the data packets to their destination hosts.
Services provided by TCP and UDP to application layer?
Most of the application layer protocols are layered on top of either TCP or UDP. Therefore, TCP and UDP have to concurrently handle the many disparate data streams sent to them from the application layer. The demultiplexing process would be hopelessly complicated and impossible to handle without some means of identifying which data stream a particular segment of data belongs to. Both TCP and UDP provide a port identifier to uniquely identify each data stream. A set of standard port numbers are assigned by the IANA to the major aplication layer protocols. These 'well known' ports make it easier to find the corresponding server for a particular protocol on a host. e.g. SMTP servers can usually be found on port 25 and HTTP servers are usually on port 80. The combination of a TCP/UDP port and an IP address uniquely identifies a particular service on a particular host. The term 'socket' is usually used to refer to the combination of the TCP/UDP port and IP address.
What is the port number of eigrp?
EIGRP uses port no. 88, but it is not use TCP or UDP, it's uses RTP(Reliable Transport Protocol).
Is DNS connectionless or connection-oriented?
DHCP is a connectionless protocols. In general, any protocol that is based on TCP port alone is a connection-oriented protocol while any protocol that is based on UDP port alone is a connectionless protocol. And a protocols that can work on both TCP and UDP port can be either a connection-oriented or a connectionless protocol depending upon the which protocol is used (TCP or UDP). For checking other protocols if they are connection-oriented or connectionless check http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
IS TCP is unreliable Protocol?
No TCP a reliable protocol whereas UDP is unreliable.
What has port numbers in its header?
both tcp and udp
What is the upward limit on TCP port numbers?
TCP port numbers, as well as UDP port numbers, are 2-byte numbers, therefore, the range is from 0 to 65535.
Combat arms port numbers for windows vista ultimate?
* Ports 12000-17000 - UDP * Port 80 and 443 - TCP * Ports 5060 and 5062 - UDP * Ports 3478 and 3479 - UDP * Ports UDP 27901:27999 * Ports TCP 10001 * Ports TCP 47600:48000
What are the specific port no of tcp and udp?
Port No. for Tranmission Control Protocal (TCP) is 6 Port No. for User Datagram Protocol (UDP) is 17
Why should telnet to UDP port fail?
A single port can be configured to listen for UDP or TCP inbound connection requests (or both). Telnet uses TCP. So when you telnet to a specific IP:port, telnet will attempt to make a TCP connection. If there is no TCP listener on the port you specify, then the connection request will be refused. It matters not if you have a UDP listener on the port. Telnet will not be able to establish a connection to a UDP port.
What is port 1151 used for?
Port 1151 is used for TCP/UDP
What port does icmp belong to?
ICMP does not have a port like TCP and UDP.
Can tcp and udp work at the same time?
Yes, and they frequently do, although on different port numbers for different protocols.

What port does SMB use?
139 & 445 (udp) and 138 & 137 (tcp)
What does a client application select for a TCP or UDP source port number?
What a client application usually selects for a TCP or UDP source port number is a random value. The value selected is generally in the range of the registered ports.
