TCP/IP and OSI Model
The TCP/IP is the most used and accepted model and not own by an institution whereas the OSI model who more a theory and less accepted globally so for that reasons I will be basing our findings on TCP/IP model.
It is basically the collection of layered network protocols that manages the communication of a network. It is made up of four(4) layers namely:
Application layer: This layer is the bridge between the client(browser) and the lower layers of the network that sends the data.
Transport layer: This layer is responsible for ensuring that data sent is arrived in it orderly manner as intended by the sender.
Internet layer: This layer's duty is to find the best and fastest route data should be send on the network.
Data Link Layer: This layer deals with the physical connection of devices with your computers that is there might be wired(Cable) or wireless(WiFi, Bluetooth). Ensuring data can be send from one device to another.
