Quick Answer: What Is Difference Between TCP And IP?

What is TCP IP explain?

Definition: TCP/IP (Transmission Control Protocol/Internet Protocol), also referred to as the Internet Protocol Suite, is the World Wide Web’s core communication system that enables every Internet-connected device to communicate with every other such device simultaneously..

How is TCP Reliable?

The reason that Transmission Control Protocol (TCP) is considered ‘reliable’ is that the protocol itself checks to see if everything that was transmitted was delivered at the receiving end (it may not have been due to packet loss).

What is TCP vs UDP?

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. … TCP does error checking and also makes error recovery, on the other hand, UDP performs error checking, but it discards erroneous packets.

Where is TCP used?

Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the Transport Layer of the TCP/IP suite. SSL/TLS often runs on top of TCP. TCP is connection-oriented, and a connection between client and server is established before data can be sent.

What are the 4 parts of an IP address?

IP Address ComponentsAddress Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E. … Default Subnet Mask. … The Network Field. … The Host Field. … Non-default Masks. … The Subnet Field.

What are the 3 major classes of an IP network?

Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.

Which is reliable TCP or IP?

Together, Transmission Control Protocol (TCP) and IP provide a reliable service, whereas User Datagram Protocol (UDP) and IP provide an unreliable one.

What is the point of TCP and IP addresses?

TCP/IP includes an Internet addressing scheme that allows users and applications to identify a specific network or host to communicate with. An Internet address works like a postal address, allowing data to be routed to the chosen destination.

Who uses TCP IP?

TCP/IP can also be used as a communications protocol in a private computer network (an intranet or an extranet). The entire Internet Protocol suite — a set of rules and procedures — is commonly referred to as TCP/IP. TCP and IP are the two main protocols, though others are included in the suite.

The TCP / IP protocol stack or suite of protocols is popular because it is the dominant communication model of the global Internet, with at least one billion hosts and another one billion websites. The protocol suite requires additional mechanisms to ensure security.


TCP and IP are two separate computer network protocols. IP is the part that obtains the address to which data is sent. TCP is responsible for data delivery once that IP address has been found.
