TCP / IP
Worksheet N° 1 Internet and its history
BRIEF HISTORY ABOUT TCP/IP
DARPA then was hired by BBN Technologies, Stanford University, and the University College London (UCL) to develop operational versions of the protocol on different hardware platforms.
They developed four different versions: TCP v1, TCP v2, a third divided in two: TCP v3 and IP v3 ,and then the TCP / IP v4 version : protocol that is still in use on Internet.
Several different prototypes of TCP / IP protocols were developed in many research centers between 1978 and 1983.
In March 1982, the United States Department of Defense declared the TCP / IP standard protocol for communications between networks militares.11 In 1985, the "Internet Management Centre" organized a " Workshop "for three days, attended by 250 merchants. This promote the protocol, which contributed to increased of itscommercial use.
WHAT IS INTERNET PrOTOCOL?
Allows two computers to figure out where the other is, so they can start communication. IP is a Routable Protocol; this means that the networks are divided into subnetworks and that each network must have a router which permited the device interact with another subnetworks.
What is Transmission Control Protocol?
This packets are very importants in windowing. What is windowing? Is a process by which a computer send info to the server computer. The data is break down is small parts called packets. First computer start sending packets in groups to the second computer. This groups will double the amount as time passes.
KEY ELEMENTS OF TCP/IP
Address that are use to signify every device and every conduct of this device on the network.
With this you can prevent computers communicate althought they are connected to the same network.
Is the same of router process. First I search what I want in my local network. If I couldnt find it, the computer goes to the router or Default Gateway, which permit to search and find the info I need in others networks. In general Default Gateway is what connect the subnetwork to all the others networks.
DOMAIN NAME SERVER
Domain Name Server is like a nick name that computer stablish for important secuence of number that fulfills an very important role in the interal processes of the computer. Example: If I put in google www.cnn.com, this doesnt mean anything fot my computer. What it really cares is the secret code that this address means
Dynamic Host Configuration Protocol
Allows for the automatic distribution of IP adresses. This given IP adresses has lisans for different time. The DHCP decide if the computer continue with the same IP adreses or change.
DOMAIN NAME SERVER
WHO USE THIS PROTOCOL?What is the future of these technology?
The TCP / IP protocol is one set of network protocols on which the Internet is based and which allow the transmission of data between computers ,is the most implemented protocl in devices that acesses to the Internet.
Many programs within a data network comprises computer networks can use TCP / IP to create "connections" to each other through which can send a data flow. I personally think that this protocol will continue in our society; obviously new versions as IPv6 will be create bringing new updates and new caracteristics. Maybe in the future because we're in the era of innovation this protocol will be remplaceby by another program more efficient.
