Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.  IP is a connection-less protocol, which means that there is no continuing connection between the end points that are communicating. Each packet that travels through the Internet is treated as an independent unit of data without any relation to any other unit of data. (The reason the packets do get put in the right order is because of TCP, the connection-oriented protocol that keeps track of the packet sequence in a message.) In the Open Systems Interconnection (OSI) communication model, IP is in layer 3, the Networking Layer.  The most widely used version of IP today is Internet Protocol Version 4 (IPv4). However, IP Version 6 (IPv6) is also beginning to be supported. IPv6 provides for much longer addresses and therefore for the possibility of many more Internet users. IPv6 includes the capabilities of IPv4 and any server that can support IPv6 packets can also support IPv4 packets. ]]> 2017-10-17 12:26:27 UTC https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197736654 https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197739004 Edgar and David
TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.]]> 2017-10-17 12:31:51 UTC https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197739004 https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197742766 TCP is stream oriented, that is, TCP protocol entities exchange streams of data. Individual bytes of data (e.g. from an application or session layer protocol) are placed in memory buffers and transmitted by TCP in transport Protocol Data Units (for TCP these are usually known as "segments"). The reliabel, flow-controlled TCP service is much more complex than UDP, which only provides a Best Effort service. To implement the service, TCP uses a number of protocol timers that ensure reliable and synchronised communication between the two End Systems.]]> 2017-10-17 12:40:04 UTC https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197742766 https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197745297 The IP (Internet Protocol) is a protocol that uses datagrams to communicate over a packet-switched network, such as the Internet. The IP protocol operates at the network layer protocol of the OSI reference model and is a part of a suite of protocols known as TCP/IP. Today, with over 1.5 billion users worldwide, the current Internet is a great success in terms of connecting people and communities. Even though the current Internet continues to work and is capable of fulfilling its current missions, it also suffers from a relative classification, a condition where technological innovation meets natural resistance, as exemplified by the current lack of wide deployment of technologies such as multicast or Internet Protocol version 6 (IPv6).]]> 2017-10-17 12:44:57 UTC https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197745297 https://padlet.com/bolanle_kareem/zwd9v6q45ty2/wish/197756747
