These documents are being revised all the time, so the RFC number keeps changing. You will have to look in rfc-index.txt to find the number of the latest edition. Stallings received his doctorate in computer science from Massachusetts Institute of Technology.

  • Sending email can be done using the SMTP, or Simple Mail Transfer Protocol.
  • D) except to the extent that any higher limit applies under the Product Warranty in the case of Connected Equipment, limit our monetary liability to you to the price that you paid for the Product.
  • Additionally, there is less manual configuration of the routing tables, since routers learn from one another about their existence and available routes.
  • The Internet’s success in the 21st century has encouraged analysts to investigate the origin of this network.

However with most media, there are efficiency advantages to sending one datagram per packet, and so the distinction tends to vanish. Note that some of the protocols described above were designed by Berkeley, Sun, or other organizations. Thus they are not officially part of the Internet protocol suite. However they are implemented using TCP/IP, just as normal TCP/IP application protocols are. Since the protocol definitions are not considered proprietary, and since commercially-support implementations are widely available, it is reasonable to think of these protocols as being effectively part of the Internet suite.


(SMTP is “simple mail transfer protocol.) We assume that a computer called TOPAZ.RUTGERS.EDU wants to send the following message. Note by the way that the terms “datagram” and “packet” often seem to be nearly interchangeable. Technically, datagram is the right word to use when describing TCP/IP. A datagram is a unit of data, which is what the protocols deal with. A packet is a physical thing, appearing on an Ethernet or some wire. In most cases a packet simply contains a datagram, so there is very little difference.

Note that the list above is simply a sample of the sort of services available through TCP/IP. However it does contain the majority of the “major” applications. The other commonly-used protocols tend to be specialized facilities for getting information of various kinds, such as who is logged in, the time of day, etc. The Internet’s success in the 21st century has encouraged analysts to investigate the origin of this network. Much of this literature adopts a teleological approach.

The Department of Electronic Engineering aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. Students are provided with their examination results within 20 working days of the end of any given examination period. The Department will also endeavour to return all coursework feedback within 20 working days of the submission deadline. The Department would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback.
