Network 1-2 Poll

Front

What is a logical topology in networking?

Back

A logical topology refers to the way data flows within a network, regardless of its physical layout. It illustrates how devices communicate and share information.

Front

What is the OSI Model?

Back

The OSI Model (Open Systems Interconnection Model) is a conceptual framework used to understand network interactions in seven layers, from physical transmission to application services.

Front

What does the Session layer of the OSI Model do?

Back

The Session layer (Layer 5) manages sessions between applications, establishing, maintaining, and terminating connections.

Front

What is the purpose of a network map?

Back

A network map visually represents the devices and connections in a network, showing how they are logically interconnected.

Front

What is the difference between Telnet and SSH?

Back

Telnet is an unencrypted protocol for remote access, while SSH (Secure Shell) provides encrypted communication for secure remote access.

Front

What is EMI and how does it affect networks?

Back

Electromagnetic Interference (EMI) is noise that can disrupt signals in a network, leading to physical layer failures.

Front

What is the function of the Data Link layer in the OSI Model?

Back

The Data Link layer (Layer 2) is responsible for node-to-node data transfer and error detection and correction, adding both a header and a trailer to data packets.

Front

What is a wiring diagram?

Back

A wiring diagram is a visual representation of the physical connections and layout of a network's components, showing how they are wired together.

Front

What is the role of the Transport layer in the OSI Model?

Back

The Transport layer (Layer 4) ensures reliable data transfer between devices, managing error correction and flow control.

Front

What is the purpose of the Physical layer in the OSI Model?

Back

The Physical layer (Layer 1) deals with the physical connection between devices, including cables, switches, and the electrical signals used for data transmission.
