Classify how applications, devices, and protocols relate to the OSI model layers

Question 1

What is a MAC Address?

Answer 1

Media Access Control
It is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet. Logically, MAC addresses are used in the media access control protocol sub layer

Question 2

What OSI Layer is the MAC address associated with?

Answer 2

Data Link Layer

Question 3

What is a IP address?

Answer 3

Internet Protocol
It is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: “A name indicates what we seek. An address indicates where it is. A route indicates how to get there.”

Question 4

What OSI Layer is the IP address associated with?

Answer 4

Network Layer

Question 5

What is EUI-64?

Answer 5

Extended Unique Identifier 64 Bit

It is a 64 bit MAC address designed to work with IPv6, it also makes up the last 64 bits of the IP address.

Question 6

What OSI Layer is the EUI-64 associated with?

Answer 6

Data Link Layer

Question 7

What are Frames ?

Answer 7

is concerned with packaging data into frames and transmitting those frames on the network.

Question 8

What OSI Layer are Frames associated with?

Answer 8

Data Link Layer

Question 9

What are Packets ?

Answer 9

The term packet describes the logical grouping of data.
Packet switching: With packet switching, a data stream is divided into packets. Each packet has a Layer 3 header, which includes a source and destination Network Layer 3 address.
Another term for packet switching is routing

Question 10

What OSI Layer are Packets associated with?

Answer 10

Network Layer

Question 11

What is a Switch?

Answer 11

A network device that uses the MAC addresses of connected devices to make it’s forwarding decisions.

Question 12

What OSI Layer is a Switch associated with?

Answer 12

Data Link Layer

Question 13

What is a Router?

Answer 13

Routers make there forwarding decisions based on the IP address of the packets

Question 14

What OSI Layer is a Router associated with?

Answer 14

Network Layer

Question 15

What is a Multi-layer switch?

Answer 15

A switch that can perform router functionality.

Question 16

What OSI Layer is a Multi-layer associated with?

Answer 16

Data Link Layer and Network Layer
