what is difference between udp and tcp/ip protocols.

TCP / IP

[Transmission control protocol / Internet Protocol]

TCP/IP is a universal standard protocols suite; it allows network connectivity between different n/w services.

TCP/IP widely used today, because it is scalable and reliable protocol.

Every operating systems enables TCP/ IP support inbuilt. It supports almost all network protocols so it is one of the common ways to communicate all network base services each others.

TCP/IP is a part of the OSI model.

IP - Internet-Protocol

Internet Protocol is responsible for moving packet of data from one node to another node over networks. It forwards each “packet” based on IP address of source and destinations.

TCP - Transmission-Control-Protocol

TCP is a connection-oriented protocol responsible for sending and verifying the date between client and server over networks.

It keeps the packet information like, whether the packet correctly delivery from client to server over the period of time, any connection failures, requesting time out and packets missing etc.

UDP - User Datagram Protocol

UDP is a connectionless protocol responsible for sending the date between client and server over networks.

It does not keeps any information of packets and it won’t get any acknowledgement from remote machine whether the packet correctly delivered or not, connection failure etc. *UDP does broadcast.
