what is TCP/IP?

Answer 1

TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, manages the assembling of a message or file into smaller packets that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination. Each gateway computer on the network checks this address to see where to forward the message. Even though some packets from the same message are routed differently than others, they'll be reassembled at the destination.

TCP/IP uses the client/server model of communication in which a computer user (a client) requests and is provided a service (such as sending a Web page) by another computer (a server) in the network. TCP/IP communication is primarily point-to-point, meaning each communication is from one point (or host computer) in the network to another point or host computer. TCP/IP and the higher-level applications that use it are collectively said to be "stateless" because each client request is considered a new request unrelated to any previous one (unlike ordinary phone conversations that require a dedicated connection for the call duration). Being stateless frees network paths so that everyone can use them continuously. (Note that the TCP layer itself is not stateless as far as any one message is concerned. Its connection remains in place until all packets in a message have been received.)

Many Internet users are familiar with the even higher layer application protocols that use TCP/IP to get to the Internet. These include the World Wide Web's Hypertext Transfer Protocol (HTTP), the File Transfer Protocol (FTP), Telnet (Telnet) which lets you logon to remote computers, and the Simple Mail Transfer Protocol (SMTP). These and other protocols are often packaged together with TCP/IP as a "suite."

Personal computer users with an analog phone modem connection to the Internet usually get to the Internet through the Serial Line Internet Protocol (SLIP) or the Point-to-Point Protocol (PPP). These protocols encapsulate the IP packets so that they can be sent over the dial-up phone connection to an access provider's modem.

Protocols related to TCP/IP include the User Datagram Protocol (UDP), which is used instead of TCP for special purposes. Other protocols are used by network host computers for exchanging router information. These include the Internet Control Message Protocol (ICMP), the Interior Gateway Protocol (IGP), the Exterior Gateway Protocol (EGP), and the Border Gateway Protocol (BGP).

Answer 2

the internet protocol suite is the set of communications protocols that implement the protocol stack on which the internet and maximum commercial networks run. this is typically observed as the TCP/IP protocol suite, after both maximum substantial protocols in it: the Transmission administration Protocol (TCP) and the internet Protocol (IP), that were also the first 2 defined. the internet protocol suite — like many protocol suites — might want to be considered as a collection of layers. each and each layer solves a collection of issues with reference to the transmission of archives, and promises a nicely-defined provider to the better layer protocols in accordance to utilizing facilities from some decrease layers. top layers are logically in the route of the person and take care of better precis archives, in accordance to diminish layer protocols to translate archives into kinds that could want to ultimately be bodily transmitted. the unique TCP/IP reference style consisted of four layers, yet has advanced right into a 5 layer style. The OSI style describes a collection, seven layer stack for networking protocols. Comparisons between the OSI style and TCP/IP provides you better perception into the magnitude of the factors of the IP suite, yet may also reason confusion, because the definition of the layers are really diverse.

Answer 3

It's a network protocol.

It defines the hardware architecture of a network, and how the network works such as trasmission, access and error handling.

Just like we're communicating in english. We need certain rules that we both must obey so that we will understand each other. The rules we obey is language grammar.

When 2 computers wants to communicate and exchange data, they both need to follow a set of rules, so that they could accept data from each other. TCP/IP is that set of rules a computer need to follow

There are lots of details covered by a network protocol you should read them up in the internet.

But before you go into the details of TCPIP protocol, you need to learn about the basic of networks, types of transmission, error handling, and network access control.

Answer 4

TCP/IP is a transport conrol protocol suite consisting about more than 20 differrent protocols and services. it is a standard on which computers on networks establish link and transfers data.
tcp is itself transmission control protiocol
an ip is internet protocol
tcp/ip together forms a atandard for communication of netwaorks

Answer 5

Internet protocol address, you need one everyone on the internet has one, its a unique set of numbers that identify you, kinda like your street address, only all numbers. It can be used to authenticate you on sites, or to block you from accessing sites.
