Is nntp still used

The USENET (and therefore NNTP) is used since the early days of the internet. Although Mailing lists and RSS feeds doing something similar, the USENET is still widely used today.

What is NNTP protocol used for?

The full form of NNTP is Network news transfer protocol. NNTP is an application protocol that transports Usenet news articles (netnews) among the news servers so that the end-user client applications can post/read the articles.

What is the advantage of NNTP?

It provides extra fast transmission by using less expensive connections.

What is the difference between USENET and NNTP?

Network News Transfer Protocol (NNTP) is the underlying protocol of UseNet, which is a worldwide discussion system which contains posts or articles which are known as news. Network News Transfer Protocol is used to transfer news from one network to another. It is designed specifically to transfer news/articles.

Does NNTP use TCP or UDP?

NNTP is a TCP-based service. NNTP servers use port 119. NNTP clients (including servers transferring news to other servers) use ports above 1023.

Is NNTP secure?

The NNTP itself has access to the application layer and for this relies directly on the TCP protocol, which has the advantage of ensuring both a secure and reliable transfer of data.

What is NNTP in Internet technology?

Network News Transfer Protocol (NNTP) historical framework comes from Usenet, an early message transfer system. The Usenet system originally communicated over telephone connections between the servers and ultimately transformed into the Internet protocol known as NNTP.

Is Usenet safer?

Usenet is also safe because of the way it distributes its data. There's no P2P. A file is broken down into multiple pieces and then sent to a decentralized network of servers which you connect to securely via SSL encryption.

Which software is used to read newsgroups?

A newsreader is an application program that reads articles on Usenet distributed throughout newsgroups. Newsreaders act as clients which connect to a news server, via the Network News Transfer Protocol (NNTP), to download articles and post new articles.

What are the disadvantages of newsgroups?

Newsgroup messages are posted to a bulletin board that the subscriber must visit to read. Mailing lists and newsgroups share many advantages (convenience, greater anonymity, and speed of communication) and disadvantages (computer access required, impersonal nature, junk mail, and lack of graphics in older programs).

Do Usenet groups still exist?

While some die-hard fans are still using Usenet for its original purpose, most of the userbase is there for fast, anonymous, and, unfortunately, often illegal file sharing.

When did Usenet shut down?

In 2008, Verizon Communications, Time Warner Cable and Sprint Nextel signed an agreement with Attorney General of New York Andrew Cuomo to shut down access to sources of child pornography. Time Warner Cable stopped offering access to Usenet.

Can you access Usenet for free?

There is a completely free way to access Usenet that we mentioned earlier—Google Groups. Google acquired an archive of Usenet posts many years ago and continues to index Usenet newsgroups and conversations.

Which protocol is used for broadcasting?

The Internet Protocol Version 4 (IPv4), which is the primary networking protocol in use today on the Internet and all networks connected to it, supports broadcast, but the broadcast domain is the broadcasting host's subnet, which is typically small; there is no way to do an Internet-wide broadcast.

Which protocol layer is used for voice traffic?

Due to the time-sensitive nature of voice traffic, UDP/IP was the logical choice to carry voice. More information was needed on a packet-by-packet basis than UDP offered, however. So, for real-time or delay-sensitive traffic, the Internet Engineering Task Force (IETF) adopted RTP.

Which protocol is used to carry voice traffic?

Common VoIP protocols include real-time transport protocol (RTP), designed to carry streaming audio and video. VoIP protocols such as RTP rely upon session and signaling protocols including session initiation protocol (SIP, a signaling protocol) and H. 323.

What is widely used protocol to protect the transfer of sensitive information?

Hypertext transfer protocol secure (HTTPS) is the secure version of HTTP, which is the primary protocol used to send data between a web browser and a website. HTTPS is encrypted in order to increase security of data transfer.

Is Youtube using TCP or UDP?

Because the delay is not critical and TCP transfers can be easily handled over HTTP and web browsers without the need for additional plugins and software, video streaming services such as Netflix, Hulu, and Youtube all use TCP to reduce the buffer time and avail other facilities.

Which protocol is best for streaming?

Using adaptive bitrate streaming, HTTP-based protocols deliver the best video quality and viewer experience possible — no matter the connection, software, or device. Some of the most common HTTP-based protocols include MPEG-DASH and Apple's HLS.

Does Instagram use TCP or UDP?

"Instagram" uses TCP protocol for communication.
