(In telecommunications, aprotocol data unit (PDU)is information that is transmitted as a single unit among peer entities of a computer network. Protocol data unitsare relevant in relation to each of the first four layers of theOSImodel as follows: Thephysical layer(layer 1)PDUis thebit. The...
TCP is a connection-oriented, end-to-end reliable protocol designed to fit into a layered hierarchy of protocols which support multi-network applications. The TCP provides for reliable inter-process communication between pairs of processes in host computers attached to distinct but interconnected compute...
The TCP/IP model consists of five layers: the application layer, transport layer, network layer, data link layer and physical layer. The first four layers provide physical standards, network interface, internetworking, and transport functions that correspond to the first four layers of the OSI mode...

Network access layer.The network access layer, sometimes referred to as thedata link layer, manages the network infrastructure that enables computer communication over the internet. The main components include device drivers,network interface cards, ethernet connections and wireless networks. ...
Internet Layer An internet layer is a second layer of TCP/IP layes of the TCP/IP model. It is also known as a network layer. The main work of this layer is to send the packets from any network, and any computer still they reach the destination irrespective of the route they take. ...
crucial for informed decision-making in network design. It empowers professionals to optimize performance based on specific application requirements. Moreover, the delicate balance between TCP and UDP ensures efficient communication, paving the way for reliable and speedy data transmission in computer ...
Datalink layer The datalink layer (also called the link layer, network interface layer, or physical layer) is what handles the physical parts of sending and receiving data using the Ethernet cable, wireless network, network interface card, device driver in the computer, and so on. ...
It's lightweight and doesn't place unnecessary strain on a network or computer. The disadvantages of TCP/IP include the following: It's complicated to set up and manage. The transport layer doesn't guarantee the delivery of packets.
