They can be sent and received regardless if the clients or server are using Windows, Macintosh or other types of platforms. The recipient uses a TCP software package to gain access to the packets. This software package scans all the packets sent and notifies the recipient if any are missing. Like HTTP, HTTPS is also responsible for sending and receiving web pages, but provides an encrypted version of HTTP for more secure web transactions. To make sure that you are safe online, you should try to use HTTPS for any webpage that has sensitive data such as usernames or passwords.

But if you need to know any details of the technology, you will want to read the standards yourself. Throughout the text, you will find references to the standards, in the form of “RFC” or “IEN” numbers. The final section of this document tells you how to get copies of those standards. The newest book by award-winning author William Stallings, provides a clear and comprehensive survey of computer networks and leading edge Internet technologies. This top down approach is organized in a modular fashion permitting professors or professionals to design a course or plan of study to meet their own needs.

Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University’s policy on the Approval of Modifications to Existing Taught Programmes of Study. There are four different layers within the TCP/IP model and each layer is responsible for different parts of the communication process. Currently most IP addresses are using the IPv4 format, based on 4 numbers between 0 and 255 sepearated by a dot. Every computer or device connected to the Internet has an IP address.

More recently, the Department of Defense issued a MILSPEC definition of TCP/IP. This was intended to be a more formal definition, appropriate for use in purchasing specifications. However most of the TCP/IP community continues to use the Internet standards.

One of the advantages of TCP/IP is that if in case the network was render inoperative then the reaming IP packets will still function as normal. This is quite important because it means that the packets would not stop working just because it is not complete.

At first, you might think that IP should simply settle on the smallest possible size. Unfortunately, this would cause serious performance problems. When transferring large files, big packets are far more efficient than small ones.

  • They maintain a directory of domain names and translate them to numerical IP addresses.
  • In order to give a bit better idea what is involved in the application protocols, I’m going to show an example of SMTP, which is the mail protocol.
  • Since they are both doing file transfers, one end of the connection involves the well-known port number for FTP.
  • It is fairly common for implementations to use 576-byte datagrams whenever they can’t verify that the entire path is able to handle larger packets.
  • And supports network packets containing control, error, and informational messages.

The description above indicated that the IP implementation is responsible for getting datagrams to the destination indicated by the destination address, but little was said about how this would be done. The task of finding how to get a datagram to its destination is referred to as “routing”. In fact many of the details depend upon the particular implementation.

4 Packet Switching

The MILSPEC version is intended to be consistent with it. – If the destination is local, the node can initiate direct communication. – If the destination is not local a gateway must be used. – Once the datagram is prepared it is passed to the network access layer. – The NAL transmits the datagram to the media to begin its journey.
