Question 23

It is an open standard for all communication systems.

Answer 23

OSI Model

Question 24

Seven Layers

Answer 24

• Application Layer (Layer 7)
• Presentation Layer (Layer 6)
• Session Layer (Layer 5)
• Transport Layer (Layer 4)
• Network Layer (Layer 3)
• Data Link Layer (Layer 2)
• Physical Layer (Layer 1)

Question 25

This layer defines the protocol which enables the user to interact with the network. For example, FTP, HTTP etc.

Answer 25

Application Layer

Question 26

This layer defines how data should flow between hosts. Major protocol at this layer is Transmission Control Protocol (TCP). This layer ensures data delivered between hosts is in order and is responsible for end-to-end delivery.
