WGU C172 Introduction to Networking Concepts
TCP\/IP – Answer stands for transmission control protocol\/internet protocol and is a
set of protocols used to connect network devices to each other.
Application Layer – Answer 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 – Answer This layer 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 – Answer This layer defines the logical transmission protocols for the
whole network. The main protocols that live in this layer are internet protocol (IP),
internet control message protocol (ICMP), and address resolution protocol (ARP).
Network Interface Layer – Answer This TCP\/IP model layer establishes how data
should be physically sent through the network.
OSI (Open System Interconnection) model – Answer model consists of a seven-layer
architecture that organizes the sending of data from hosts across a network
OSI (Open System Interconnection) model – Answer was developed by the
International Standards Organization (ISO) after the TCP\/IP model to provide greater
granularity of networking assignments within the model.
Physical Layer – Answer This layer is 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.
Data Link Layer – Answer This layer is responsible for the error-free delivery of data
to the receiving device or node. This layer is implemented through the use of devices
such as switches and bridge devices, as well as anything with a network interface,
like wireless or wired network cards.
Network Layer – Answer This layer is 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.
Transport Layer – Answer This layer provides services to the application layer and
receives services from the network layer. It is responsible for the reliable delivery of
data. It segments and reassembles data in the correct order for it to be sent to the
receiving device. It may also handle the reliable delivery of data and any retries of<\/p>\n","protected":false},"excerpt":{"rendered":"
