A Computer Network is a set of devices (Nodes) that are connected to each other by communication links to share digital information. Computer Network is broadly divided into 3 types. They are as follows :
Network Model :
OSI Reference Model : The OSI Model is divided into 7 layers :
The Layers are as follows :
TCP/IP Reference Model : Transport Layer : Some of the Responsibilities of Transport Layer are as Follows :
Transmission Control Protocol (TCP) :
Services offered by the TCP are as follows :
Advantages :
Disadvantages :
User Datagram Protocol (UDP) :It is a transport layer protocol. It is an unreliable and connectionless protocol. It is much faster, simpler, and efficient than TCP. However, it doesn’t check errors due to which Bandwidth is saved. It is widely used in real-time services like videogame, voice, or video communication The packets sent by the UDP are called user datagrams. Services offered by the UDP are as follows :
Advantages :
Disadvantages :
Real-Life Examples of TCP :
Real-Life Examples of UDP :
Hence, these were the Real-Life Examples of TCP and UDP. Why does DNS use UDP and not TCP? |
