TCP/IP AND OSI MODELS WGU D315
TEST
Application Layer (TCP/IP)
This layer is responsible for the communication protocols between nodes. The
protocols in this layer include hypertext transfer protocol-HTTP and HTTPS,
Secure Shell-SSH, and network time protocol-NTP, among many others.
Transport Layer (TCP/IP)
This layer of the OSI model is responsible for the end-to-end transport of data.
The protocols that live in this layer are transmission control protocol TCP and
user datagram protocol UDP.
Network Layer (TCP/IP)
This layer defines the logical transmission protocols for the whole network. The
major protocols residing in this layer include internet protocol (IP), internet
control message protocol (ICMP), and address resolution protocol (ARP).
Network Interface Layer (TCP/IP)
This layer defines how data should be physically transmitted across the
network.
Physical Layer (OSI)
Responsible for the physical connections of the devices in the network. This
layer is implemented through the use of devices such as hubs, repeaters, modem
devices, and physical cabling. unit = bits
, Data Link Layer (OSI)
Responsible for the delivery of data devoid of errors to the device or node
receiving it. This is done based on the use of devices like switches and bridge
devices, as well as anything with a network interface, such as wireless or wired
network cards. unit = packets
Network Layer (OSI)
Responsible for the transmission of data between hosts in different networks as
well as routing of data packets. This layer is implemented through the use of
devices such as routers and some switches. unit = frames
Transport Layer (OSI)
It provides services to the application layer, and it receives services from the
network layer. Ensuring the reliable delivery of data is the protocol's most
important role. It is responsible for segmentation and reassembly of data in the
correct order it should be sent to the receiving device. It may also handle the
reliable delivery of data and any retries of data that are lost or corrupted. Heart
of the OSI model.
Session Layer (OSI)
This layer is responsible for the establishment and maintenance of connections,
sessions, and authentication.
