Explanation

In OSI reference model, when data packet moves from lower layers to higher layer, headers get removed.

Whereas when the data packet moves from higher layer to lower layers, headers are added.

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

In the Internet Protocol stack (also known as the OSI model), the fifth layer is the Session Layer.

When data is sent from device A to device B, the Session Layer at device B is responsible for managing and controlling the connections between the two devices,

ensuring that the data exchange occurs correctly and efficiently.

Explanation

Data transmission is the process of sending digital or analog data over a communication medium to one or more computing, network, communication or electronic devices.

Explanation

IP and DNS Routes are working on the network.

Explanation

A passive topology means that devices on the network simply listen for signals and do not actively amplify or forward the signal along the network.

The Bus topology is a classic example of this.

Where data is transmitted directly on the shared cable without any intermediary device actively boosting the signal

Explanation

CSMA/CD is used in BUS topology to manage how devices share the communication line and avoid data collisions.

It listens before sending data and stops transmission if a collision is detected — ensuring efficient use of the medium.

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

Bridges are used to connect similar LANs that use the same network protocols.

They help manage traffic and reduce collisions by dividing networks into segments.

Explanation

USB 3.0 is a high-speed connection standard that can transfer data at speeds of up to 5 Gbps (gigabits per second), making it ideal for high data transfer.
