TCP (transmission control protocol) and IP (internet protocol) "TCP/IP were developed by a Department of Defense (DOD) research project to connect a number different networks designed by different vendors into a network of networks (the "Internet"). It was initially successful because it delivered a few basic services that everyone needs (file transfer, electronic mail, remote logon) across a very large number of client and server systems. Several computers in a small department can use TCP/IP (along with other protocols) on a single LAN (local area network). The IP component provides routing from the department to the enterprise network, then to regional networks, and finally to the global Internet. On the battlefield a communications network will sustain damage, so the DOD designed TCP/IP to be robust and automatically recover from any node or phone line failure also the U.S. DoD created the TCP/IP reference model because it wanted a network that could survive any conditions, even a nuclear war. This design allows the construction of very large networks with less central management. However, because of the automatic recovery, network problems can go undiagnosed and uncorrected for long periods of time. .
Description.
TCP/IP Technology.
The technical aspects of TCP/IP, related protocols, and the environments in which these protocols operate. Because the primary focus of this document is routing (a layer 3 function), the discussion of TCP (a layer 4 protocol) will be relatively brief. .
TCP can recognize duplicate messages and will discard them appropriately. If the sending computer is transmitting too fast for the receiving computer, TCP can employ flow control mechanisms to slow data transfer. TCP can also communicate delivery information to the upper-layer protocols and applications it supports. .
IP is the primary layer 3 protocol in the Internet suite. IP provides error reporting and fragmentation and reassembly of information units, for transmission over networks with different maximum data unit sizes.
The "tunnel" is the TCP/IP protocols. ... TCP/IP is broken down into two unique underlying protocols, TCP and IP. ... Like the OSI Model, TCP/IP has layers. ... IP is part of the Internet layer of TCP/IP. ... The Transport layer of the TCP/IP protocol suite contains the TCP protocol. ...
Explain what levels of the OSI model does TCP/IP function? ... TCP/IP and its components relate to these layers. ... In a similar comparison, TCP/IP as OSI monitors and controls data that's sent across the network while UDP doesn't. ... OSI's network layer corresponds to TCP/IP's Internet layer. ... The TCP/IP model also corresponds with OSI model on the data link and physical layer it is equivalent to TCP/IP subnet. ...
The client uses the IP address to bind to the network. If the IP address is associated with any configuration parameters, the parameters are incorporated into the client's TCP/IP configuration. ... The preceding chapters have pointed out several times that broadcast messages don't cross TCP/IP routers. Does that mean that a DHCP client can't obtain an IP address from a DHCP server on another subnet? ... In Figure 14.17, BOOTP is enabled on the router, which must, of course, be configured to route TCP/IP traffic. ...
These two methods are TCP/IP and cryptography. While the TCP/IP protocol was an initial first attempt at data security and integrity, it is insufficient. ... These are TCP/IP and Cryptography. TCP/IP sessions can be captured, however, by unauthorized personnel using devises such as IP packet sniffers (Computer Reseller News PG). ... Unlike cryptography, TCP/IP messages are commonly intercepted using sniffer packets. ...
Between 1982 and 1987, Bob Kahn and Vint Cerf became key members of a team that created TCP/IP (Transmission Control Protocol/Internet Protocol), the common language of all Internet computers. After the TCP/IP formation, the loose collection of networks which made up the ARPAnet is seen as an "Internet" (an inter-connected system linked together in a network), and the Internet, as we know it today, was conceived. ... It's up to the TCP protocol to put the packets back in the right order which together create the entire TCP/IP language process among computers. ...
Its only task is to obtain the hardware addresses of TCP/IP hosts on broadcast-based networks. ... DHCP DHCP stands for Dynamic Host Configuration Protocol, and is used to centrally manage TCP/ IP configurations of client nodes. ... * Not only are the TCP/ IP addresses handed out, so are all the related configuration settings like the subnet mask, default router, DNS server, that are required to make TCP/ IP work correctly... * DHCP works across most TCP/ IP routers and assigns IP's according to the subnet the request came from... This helps recover TCP/ IP addresses that ar...
Because maintaining a central list of domain name/IP address correspondences would be impractical, the lists of domain names and IP addresses are distributed throughout the Internet in a hierarchy of authority. ... Relative to the TCP/IP suite of protocols (which are the basis for information exchange on the Internet), HTTP is an application protocol FTP (File Transfer Protocol) a standard Internet protocol, is the simplest way to exchange files between computers on the Internet. Like the Hypertext Transfer Protocol which transfers displayable Web pages and related files, and the Simple Mail T...
Schneider et al) Unique features of the internet include: The TCP/IP internet protocol Still is one of the basic operations that the internet rely on, the Transmission Control Protocol(TCP) and the Internet Protocol(IP). ... When computer's transmit this several layer TCP/IP program on a network, internet is established. ... Another protocol is one such as TCP that provides services needed by many applications. ... This address, known as an IP address, is assigned to computers either manually (static IP addressing) or through some sort of address server (dynamic IP addressing)....
