Answer:
The data-link layer
Explanation:
The physical layer and data-link layer are often confused a lot especially in terms of what they do in the TCP/IP 7 layer protocol. The physical layer as the name suggests represents the physical devices like the cables and the connectors that join or interconnect computers together. This layer is also responsible for sending the signals over to other connections of a network. The data-link, on the other hand, translates and interprets these sent binary signals so that network devices can communicate. This layer is responsible in adding mac addresses to data packets and encapsulating these packets into frames before being placed on the media for transmission. Since it resides in between the network layer and the physical layer, it connects the upper layers of the TCP/IP model to the physical layer.
Standard Tree Protocol (STP) is a networking protocol that was made by Radia Perlman. It makes a single path over a network, averting any loops from happening. Even if there are multiple paths to the same destinations. It has two never versions which is 802.1s and 802.1w.
Answer:
The TCP/IP is the transmission control protocol and internet protocol and in the TCP/IP model the transport layer is the second layer.
The primary responsibility of this layer is that it is basically used to deliver messages to the host and that is why it is known as end to end layer.
It basically provide the point to point connection between the destination to server host for delivering the various types of the services efficiently and reliably.
In the TCP/IP model the transport layer are basically responsible for transferring the data or service error free between the server to destination host.

check your app permissions it may be blocking them or try resetting the app
