Answer:
waxing crescent: first quarter waning gibbous: third quarter
Explanation:
The moon is waxing (getting larger) in the first quarter after the new moon. It is waning (getting smaller) in the third quarter, after the full moon at the end of the second quarter.
The shape of the moon is a "crescent" when it is less than a semicircle. It is "gibbous" when it is more than a semicircle. As it waxes, the crescent grows until the moon is half-full at the end of the first quarter, then it is a waxing gibbous moon through the second quarter until it is full at the end of the quarter. Following the full moon, it is waning gibbous until it becomes half-full again at the end of the third quarter. Finally, it is a waning crescent through the fourth quarter until the new moon.
waxing crescent: first quarter waning gibbous: third quarter

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.
