Which one is better TCP or UDP?
TCP is comparatively slower than UDP.
UDP is faster, simpler and more efficient than TCP.
Retransmission of lost packets is possible in TCP, but not in UDP.
There is no retransmission of lost packets in User Datagram Protocol (UDP)..
Is FTP secure?
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.
Why is FTP bad?
FTP Lacks Security FTP is inherently an non-secure way to transfer data. When a file is sent using this protocol, the data, username, and password are all shared in plain text, which means a hacker can access this information with little to no effort.
Is TCP secure?
Since TCP does not provide any data encryption functions, anyone can gain any valuable information. TCP can not protect connections against the unauthorized access attacks. TCP certifies a peer entity by a source IP address and a port number. However, it is possible to modify the source address and port number.
Is TCP IP reliable?
TCP is a reliable stream delivery service which guarantees that all bytes received will be identical and in the same order as those sent. Since packet transfer by many networks is not reliable, TCP achieves this using a technique known as positive acknowledgement with re-transmission.
Is TCP model better than OSI?
TCP/IP does not have a clear distinction between these three. OSI model gives guidelines on how communication needs to be done, while TCP/IP protocols layout standards on which the Internet was developed. So, TCP/IP is a more practical model.
What’s the difference between TCP and IP?
The difference is that TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. In other words, IP obtains the address and TCP guarantees delivery of data to that address.
Can FTP be hacked?
FTP user and password can not be hacked by any masterminds. FTP only becomes unsafe in the case when we share our user and passwords with any body else it can’t get hacked. FTP is the secured way to share the files.
Is UDP secure?
Security for UDP The connection-oriented methods of TCP make security much easier to implement in that protocol in UDP. However, there are encryption standards available for UDP. The main option that directly aims at security UDP is the Datagram Transport Layer Security protocol or DTLS.

Is TCP or UDP better for streaming?
As for streaming it’s better to use UDP, first because it lowers the load on servers, but mostly because you can send packets with multicast, it’s simpler than sending it to each connected client. It depends. How critical is the content you are streaming? If critical use TCP.
Is TCP still used?
Today, it is the main protocol used in all Internet operations. TCP/IP also is a layered protocol but does not use all of the OSI layers, though the layers are equivalent in operation and function (Fig. 2). The network access layer is equivalent to OSI layers 1 and 2.
Is UDP or TCP more secure?
TCP isn’t more secure than UDP, it is more “reliable” as it is stateful and requires acknowledgment of each segment. UDP is stateless and just sends segments without knowing of the client gets them or not.
Which is more secure FTP or TFTP?
FTP provides minimal security through user logins. TFTP does not use logins. FTP provides a reliable service through its use of TCP. TFTP does not since it uses UDP.
What does TCP stand for?
Transmission Control ProtocolTCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a set of standardized rules that allow computers to communicate on a network such as the internet.
