OSI model summative

One of the following components working at physical layer:

• Switch
• PC
• Hub
• Router

It is the layer that offers a physical address so a device’s data can be sent on the network:

• Data-Link Layer
• Network Layer
• Transport Layer
• Physical Layer

Layer 3 of the OSI model, provides an end-to-end logical addressing system so that a packet of data can be routed across several networks. Logical addressing referred to:

• MAC addresses
• IP addresses
• Memory addresses
• Computer addresses

The layer that is responsible for message encryption/decryption, compression and translation is:

• Layer 4
• Layer 5
• Layer 6
• Layer 7

HTTP, email, and end users apps works at Layer:

• 2

• 3

• 6

• 7
