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.
The python code which can be used to read dates from input, one date per line and each date's format must be as follows: March 1, 1990, is:
<h3>Python code</h3>
import datetime
inputs = []
result = []
#read the inputs
date = input()
inputs.append(date)
while not date == "-1":
date = input()
inputs.append(date)
#check if the input is in the correct format and convert it.
for date_text in inputs:
try:
date_text = datetime.datetime.strptime(date_text,"%d %B, %Y")
result.append(date_text.strftime("%d/%m/%Y"))
except ValueError:
pass
print(*result, sep = "\n")
The above code would parse the string and extract the date. The split() method was used to break the input into tokens.

Logical Link Control is the data link sublayer that identifies the network layer protocol encapsulated in the frame. The acronym of Logical Link Control is LLC.
Therefore, the answer is LLC.
