Protocol | MCQs

Explanation

A gateway is a device that connects two or more networks using different communication protocols.

It acts as a translator between systems so they can communicate effectively.

Explanation

HTTPS stands for HyperText Transfer Protocol Secure — it encrypts data for secure web browsing.

It uses SSL/TLS protocols to protect information from being intercepted or tampered with.

Explanation

A protocol is a set of rules that governs how data is transmitted and received over a network.

It ensuring that communication between devices is orderly and understandable.

Explanation

Point-to-point: Connects exactly two nodes, creating a single link between the host and the destination.

Broadcast: Sends data to all nodes in a network.

Multicast: Sends data to a specific group of nodes.

Anycast: Sends data to the nearest or best destination among a group.

Explanation

HTTPS (Hypertext Transfer Protocol Secure) is considered the best for HTTP/IP because it encrypts data between the client and server, ensuring privacy and security.

Unlike HTTP, which is unencrypted, HTTPS adds a layer of security using SSL/TLS protocols, preventing data from being intercepted during transmission.

Explanation

Packet switching is used in the Internet and most local area networks.

The Internet is implemented by the Internet Protocol Suite using a variety of Link Layer technologies.

Explanation

Telnet is an application protocol used on the Internet or local area network to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection.

Explanation

• Replying to a received email is called "replying" an email.
• This means responding to a message sent by someone else.

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

Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology in a switched LAN (Local Area Network) with redundant paths. Its primary purpose is to prevent switching loops, which can cause network instability, packet duplication, and broadcast storms.

STP achieves this by:

• Creating a spanning tree topology
• Blocking redundant paths
• Ensuring a single path for data transmission

By preventing switching loops, STP ensures a stable and efficient network operation.
