What is TCP/IP communication?

Question

What is TCP/IP communication?

Answer 1

TCP- Transmission Control Protocol

IP- Internet Protocol



The IP converts the data into packets and send it through internet and those packets are small form of the files. The IP address is the tracing id of the computer



TCP- It controls the transmission of Packets

Answer 2

There are three levels of TCP/IP knowledge. Those who administer a regional or national network must design a system of long distance phone lines, dedicated routing devices, and very large configuration files. They must know the IP numbers and physical locations of thousands of subscriber networks. They must also have a formal network monitor strategy to detect problems and respond quickly.



Each large company or university that subscribes to the Internet must have an intermediate level of network organization and expertise. A half dozen routers might be configured to connect several dozen departmental LANs in several buildings. All traffic outside the organization would typically be routed to a single connection to a regional network provider.



However, the end user can install TCP/IP on a personal computer without any knowledge of either the corporate or regional network. Three pieces of information are required:



The IP address assigned to this personal computer

The part of the IP address (the subnet mask) that distinguishes other machines on the same LAN (messages can be sent to them directly) from machines in other departments or elsewhere in the world (which are sent to a router machine)

The IP address of the router machine that connects this LAN to the rest of the world.

In the case of the PCLT server, the IP address is 130.132.59.234. Since the first three bytes designate this department, a "subnet mask" is defined as 255.255.255.0 (255 is the largest byte value and represents the number with all bits turned on). It is a Yale convention (which we recommend to everyone) that the router for each department have station number 1 within the department network. Thus the PCLT router is 130.132.59.1. Thus the PCLT server is configured with the values:



My IP address: 130.132.59.234

Subnet mask: 255.255.255.0

Default router: 130.132.59.1

The subnet mask tells the server that any other machine with an IP address beginning 130.132.59.* is on the same department LAN, so messages are sent to it directly. Any IP address beginning with a different value is accessed indirectly by sending the message through the router at 130.132.59.1 (which is on the departmental LAN).

Answer 3

TCP/IP is the communication protocol for communication between computers connected to the Internet.



TCP/IP stands for Transmission Control Protocol / Internet Protocol.

The standard defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.



Hiding inside the TCP/IP standard there are a number of protocols for handling data communication:



TCP (Transmission Control Protocol) communication between applications

UDP (User Datagram Protocol) simple communication between applications

IP (Internet Protocol) communication between computers

ICMP (Internet Control Message Protocol) for errors and statistics

DHCP (Dynamic Host Configuration Protocol) for dynamic addressing



TCP is for communication between applications.



When an application wants to communicate with another application via TCP, it sends a communication request. This request must be sent to an exact address. After a "handshake" between the two applications, TCP will setup a "full-duplex" communication between the two applications.



The "full-duplex" communication will occupy the communication line between the two computers until it is closed by one of the two applications.

Answer 4

TCP/IP is the communication protocol for the Internet.

Computer Communication Protocol



A computer communication protocol is a description of the rules computers must follow to communicate with each other.

What is TCP/IP?



TCP/IP is the communication protocol for communication between computers connected to the Internet.



TCP/IP stands for Transmission Control Protocol / Internet Protocol.



The standard defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.

Inside TCP/IP



Hiding inside the TCP/IP standard there are a number of protocols for handling data communication:



* TCP (Transmission Control Protocol) communication between applications

* UDP (User Datagram Protocol) simple communication between applications

* IP (Internet Protocol) communication between computers

* ICMP (Internet Control Message Protocol) for errors and statistics

* DHCP (Dynamic Host Configuration Protocol) for dynamic addressing



You will learn more about these standards later in this tutorial.

TCP Uses a Fixed Connection



TCP is for communication between applications.



When an application wants to communicate with another application via TCP, it sends a communication request. This request must be sent to an exact address. After a "handshake" between the two applications, TCP will setup a "full-duplex" communication between the two applications.



The "full-duplex" communication will occupy the communication line between the two computers until it is closed by one of the two applications.



UDP is very similar to TCP, but is simpler and less reliable.

IP is Connection-Less



IP is for communication between computers.



IP is a "connection-less" communication protocol. It does not occupy the communication line between two communicating computers. This way IP reduces the need for network lines. Each line can be used for communication between many different computers at the same time.



With IP, messages (or other data) are broken up into small independent "packets" and sent between computers via the Internet.



IP is responsible for "routing" each packet to its destination.

IP Routers



When an IP packet is sent from a computer, it arrives at an IP router.



The IP router is responsible for "routing" the packet to its destination, directly or via another router.



The path the packet will follow might be different from other packets of the same communication. The router is responsible for the right addressing depending on traffic volume, errors in the network, or other parameters.

Connection-Less Analogy



Communicating via IP is like sending a long letter as a large number of small postcards, each finding its own (often different) way to the receiver.

TCP/IP



TCP/IP is TCP and IP working together.



TCP takes care of the communication between your application software (i.e. your browser) and your network software.



IP takes care of the communication with other computers.



TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.



IP is responsible for sending the packets to the receiver.

Answer 6

Communication Protical.

Answer 7

It means Transmission Control Protocol/Internet Protocol.

It is a means of communication protocol/guidline/identification.
