It is the labels, which is the title of each column. For one column we can have the names, for another column, we can have a label grade. and for the third column, we can have the label scores. And the others are the graphs, formulas and the numbers, which are not an option.
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 exercise is about filling in the gaps and is related to the History of the ARPANET.
<h3>
What is the History of the ARPANET?</h3>
From the text:
In 1972, earlier designers built the <u>ARPANET </u>connecting major universities. They broke communication into smaller chunks, or <u>packets </u>and sent them on a first-come, first-serve basis. The limit to the number of bytes of data that can be moved is called line capacity, or <u>bandwidth</u>.
When a network is met its capacity the user experiences <u>unwanted pauses</u>. When the network is "slowing down", what is happening is users are waiting for their packet to leave the <u>queue</u>.
To make the queues smaller, developers created <u>mixed </u>packets to move <u>simultaneously</u>.
