OSI Model | MCQs

Explanation

A switch operates at the Data Link Layer (Layer 2) of the OSI model.

It uses MAC addresses to forward data frames within a local network.

Explanation

The Session layer is the 5th layer of the OSI (Open Systems Interconnection) model.

It is responsible for establishing, managing, and terminating sessions between two communicating devices.

The OSI (Open Systems Interconnection) model has 7 layers, which are:

1. Physical
2. Data Link
3. Network
4. Transport
5. Session
6. Presentation
7. Application

Explanation

OSI: describes seven layers that computer systems use to communicate over a network.

Explanation

 Some functions of the presentation layer include character-code translation, data conversion, data encryption and decryption, and data translation.

It connects the application layer with the layers below converting the human readable text and media to machine readable format and vice-versa.

Explanation

The MAC (Media Access Control) sub-layer is part of the Data Link Layer (Layer 2) of the OSI model.

It handles how devices access and control the transmission on the physical medium, such as Ethernet.

Explanation

• The four layers of the TCP/IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access.
• The Host-to-Host layer is equivalent to the Transport layer of the OSI model.

Explanation

The OSI (Open Systems Interconnection) model has 7 layers, which are:

1. Physical
2. Data Link
3. Network
4. Transport
5. Session
6. Presentation
7. Application

Explanation

Data link layer contains frames.
