It uses a control channel and opens new connections for the data transfer. As it uses SSL, it requires a certificate. SFTP (SSH File Transfer Protocol/Secure File Transfer Protocol) was designed as an extension of SSH to provide file transfer capability, so it usually uses only the SSH port for both data and control.
TFTP is way slower than FTP. FTP leverages the TCP acknowledgement system, which includes window size to maximize throughput. Instead, TFTP is based on UDP and implements a rudimental acknowledgement system at the appliccation level. Specifically, each piece of data sent requires an acknowledgement.
TFTP is a simplified alternative to FTP that provides no authentication and is most often used to transfer configurations to and from network devices. BTP and TFTP are inherently insecure protocols. They do not use encryption and allow both authentication and file data to traverse the network in the clear.
FTP was not built to be secure. It is generally considered to be an insecure protocol because it relies on clear-text usernames and passwords for authentication and does not use encryption. Data sent via FTP is vulnerable to sniffing, spoofing, and brute force attacks, among other basic attack methods.
TFTP stands for Trivial File Transfer Protocol. It is defined in RFC783. It is simpler than FTP, does file transfer between client and server process but does not provide user authentication and other useful features supported by FTP. TFTP uses UDP while FTP uses TCP.
The Protocol
As mentioned, TFTP uses UDP as a transport, as opposed to TCP which FTP uses, and works on port 69, you can clearly see that in the cool 3D diagram on the left. Port 69 is the default port for TFTP, but if you like, you can modify the settings on your TFTP server so it runs on a different port.They are two completely different protocols. FTPS is FTP with SSL for security. It uses a control channel and opens new connections for the data transfer. As it uses SSL, it requires a certificate.
What Port Does SFTP Use? SFTP (SSH File Transfer Protocol), not to be confused with FTPS (Secure FTP), runs on top of the SSH (Secure Shell) protocol and by default uses port 22 for communications. An SFTP server may however be configured to listen on a different port other than the default port.
TFTP, or Trivial File Transfer Protocol, is a simple high-level protocol for transferring data servers use to boot diskless workstations, X-terminals, and routers by using User Data Protocol (UDP). TFTP was primarily designed to read or write files by using a remote server.
Using FTP both the command and data channels are unencrypted. Any data sent over these channels can be intercepted and read.
TFTP doesn't support user authentication and all data is sent in clear text. The only real advantage that TFTP has over FTP is that it uses less resources. It is not widely used today, but Cisco does still use it on its devices, for example to backup a router's IOS image.
Secure Shell provides strong password authentication and public key authentication, as well as encrypted data communications between two computers connecting over an open network, such as the internet. An SSH server, by default, listens on the standard Transmission Control Protocol (TCP) port 22.
Like its' HTTPS counterpart, FTPS includes the encryption necessary to protect the data across the wire. FTPS adds support for encryption to the original FTP protocol via SSL (Secure Sockets Layer) or TLS (Transport Layer Security). FTPS uses public key encryption and FTPS servers must provide an X.
Secure variants of FTP include FTPS Implicit SSL and FTPS Explicit SSL. Both utilize SSL encryption. FTPS implicit SSL services generally run on port 990. Although still in use today, FTPS Implicit SSL is considered by many to be obsolete in favor of FTPS Explicit SSL.
SFTP offers a secure channel for transferring the files between the host. FTP is accessible anonymously, and in most cases, it is not encrypted. SFTP encrypts the data before sends it to another host. FTP is TCP/IP protocol.
Trivial File Transfer Protocol (TFTP) is a simple lockstep File Transfer Protocol which allows a client to get a file from or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a local area network.
The TFTP protocol itself is implemented on top of User Data Protocol (UDP) which in turn runs on top of the Internet Protocol (IP). UDP provides connection-less service at layer four of the OSI network protocol model.

why does TFTP use UDP? TFTP was written specifically to be fault-tolerant of missing packets so you didn't need the overhead of TCP. FTP uses TCP, TFTP uses UDP. It allows the code that runs it to be extremely small, but you lose the reliability of TCP.

An easy way to determine if the MTFTP service is working and also confirm the IP address it is listening on, would be to use the command netstat –an on the PXE server from a command prompt and look for UDP 10.37. 159.245:69 in the return. Replace the IP address with the IP Address of the server being tested.
The SMB protocol relies on lower-level protocols for transport. The Microsoft SMB protocol was often used with NetBIOS over TCP/IP (NBT) over UDP, using port numbers 137 and 138, and TCP port numbers 137 and 139. SMB/NBT combination is generally used for backward compatibility.
Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not.
Shreyas Zare, Developer of Bit Chat, a peer-to-peer instant messenger. A web server works over HTTP protocol which was developed much later than FTP protocol. FTP protocol is a stateful protocol, where the user authenticates at the start of the TCP connection and the server remembers the user till the connection ends.
The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server.
FTP stands for File Transfer Protocol and, as the name implies, it is a way of transferring files between computers. It is also one of those wonderful computer terms that's both a noun and a verb. As a noun, FTP is the name for a method of sending files, but also the name of the program that actually sends the files.
FTP is a network protocol used to transfer files from one computer to another over a TCP network. FTP uses two TCP ports: port 20 for sending data and port 21 for sending control commands. HTTP (Hypertext Transfer Protocol) HTTP is an client-server protocol that allows clients to request web pages from web servers.
FTP itself uses the TCP transport protocol exclusively, or in other words, it never uses UDP for its transport needs. Typically an application layer protocol will use one or the other. One notable exception to that is DNS or Domain Name System. FTP also is odd in the fact that it uses two ports to accomplish its task.
FTP handles both binary and text format files. SMTP stands for Simple Mail Transfer Protocol. As we know now that main difference between FTP and SMTP is that with FTP user can send and receive file to and from the computer, While SMTP is used to deliver the mail to the user's mail box configured in the e-mail server.
FTP stands for File Transfer Protocol. FTP essentially transfers these web page files to the computer server so others can access them. FTP can also be used to download files or programs from the Internet to your computer. When you download these files, you are transferring them from other servers through FTP.
Using FTP, you can download or upload files to a server that is running the FTP service. SMTP protocol is used to send email across multiple email servers/gateways. FTP allows access to files on a server. SMTP allows you to send email with file attachments and POP allows you to receive email with file attachments.
