It establishes two TCP connections: Control Connection to authenticate the user, and Data Connection to transfer the files. SMTP is what is used by Email servers all over the globe to communicate with each other, so that the assignment you submitted at 11:59 pm reaches your professor’s inbox within the deadline.
The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are used to transmit network data to and from server and client applications. The main difference between the two protocols is that TCP uses a connection-oriented transport, while UDP uses a connectionless type of communication. Several port probes are available in the base system. Each port probe uses an IP Service, which is a record that tells Discovery which port to use for a specific protocol.

Solved: Hi there, Please excuse me for this simple question I am confused about extended ACLS when we use (permit|deny) for Protocol IP,TCP,UDP on an access list I have 2 Examples below 1. access-list 102 permit tcp any 192.168.10.10 OR access-list
TCP and UDP. The most common transport protocols used are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). The difference between these two protocols is that TCP is a connection oriented protocol. That means that TCP ensures that information sent is actually received. TCP detects errors and acknowledge sent and received data.
Service: Port: Protocol: echo: 7: tcp: echo: 7: udp: discard: 9: tcp: discard: 9: udp: systat: 11: tcp: systat: 11: tcp: daytime: 13: tcp: daytime: 13: udp: netstat
TCP is a full-featured protocol that allows applications to send data reliably without worrying about network layer issues. The transmission speed of TCP is high, but not as UDP. Applications of TCP are FTP, Telnet, SMTP, DNS, HTTP, POP, NNTP, IMAP, BGP, IRC, NFS etc. These are the TCP and UDP protocols and their working along with the UDP is faster than TCP because it does not order packets (which can be done by the application layer), and it is a connection-less protocol. UDP is actually better suited for repetitive, low-priority functions like alarm monitoring. Therefore, typically, SNMP uses UDP port 161 and UDP port 162. Note: Agents use UDP 161, while the manager uses
