The first of the two different windowing features of TCP uses the Window field in the TCP header, which is also called the receiver window or the advertised window. TCP uses two separate window sizes that determine the maximum window size of data that can be sent before the sender must stop and wait for an acknowledgment. More importantly, the sender also slows down sending data into the network. When a TCP receiver signals that a packet was not received, or if an acknowledgment is not received at all, the TCP sender assumes the packet was lost, and resends the packet. Segment (sequence number), and another field used by the receiver to confirm receipt of the packets (acknowledgment number). Unlike UDP, TCP includes a field in the TCP header to number each TCP TCP senders, however, slow down the rate at which they send after recognizing that a packet was lost. UDP, by itself, does not react to packet loss, because UDP does not include any mechanism with which to know whether a packet was lost. Therefore, packets may arrive out of sequence.UDP and TCP behave very differently when packets are lost. Packets may or may not follow the same route - they are sent along whichever route gives the quickest transmission. The packets are sent individually across the network and put back together to reform the message at the other end. payload - this is part of the message itself.

header - this includes the sender's and recipient's IP addresses, the packet number, the total number of packets the message contains, plus the details of any protocols used.In packet switching, messages are broken up into very small pieces, called packets. TCP/IP uses packet switching to send data across a network. To send a large message in one go can be impractical, as both the sending and receiving node are tied up with one communication. Transmissions over a network can be extremely large. A new version - IPv6 - has been introduced, significantly increasing the number of possible addresses to trillions. However, the huge increase in internet-enabled devices led to IPv4 running out of addresses. When IPv4 was devised, the range of addresses it allowed was deemed to be sufficient. The method of addressing using four sets of digits held in 32 bits is called IPv4. When a node wants to send a message to another node, it uses the recipient node's IP address as the destination. This address consists of four sets of up to three digits, each with a maximum value of 255. IP addressingĪt the internet layer, the IP - Internet Protocol - part of the TCP/IP protocol stack needs each node to have an IP address assigned to it.

Layering allows standards to be put in place and adapted as new hardware and software is developed. The way the program encodes the message changes - the rest of the communication method remains the same. For example, different software packages (applications) may use the same transport, internet and link layers but may each use their own application layer. Layering enables standards to be developed, but also to be adapted to new hardware and software over time.

In networking, layering means to break up the sending of messages into separate components and activities.
