Multiple choice

Which of the following is a common approach to improving the scalability of blockchain networks?

  1. Increasing the block size

  2. Reducing the number of nodes in the network

  3. Using off-chain transactions

  4. Implementing sharding
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sharding is a technique that divides the blockchain network into multiple partitions, or shards, each of which processes transactions independently. This approach can significantly improve scalability by allowing multiple transactions to be processed in parallel.

Multiple choice

Multiple choice

Which of the following is a type of IoT network architecture that connects devices directly to the internet without the need for a central gateway?

  1. Star

  2. Mesh

  3. Bus

  4. Ring
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A mesh network is a type of IoT network architecture where devices communicate with each other directly, forming a self-healing and self-organizing network. This architecture is often used in applications where devices are spread over a wide area and there is no central point of control.

  1. Star

  2. Mesh

  3. Bus

  4. Ring
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A star network is a type of IoT network architecture where devices are connected to a central gateway, which then connects to the internet. This architecture is commonly used in applications where devices are located in a centralized area and there is a need for a single point of control.

Multiple choice

Which of the following is a type of IoT network architecture where devices are connected to each other in a linear fashion?

  1. Star

  2. Mesh

  3. Bus

  4. Ring
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A bus network is a type of IoT network architecture where devices are connected to each other in a linear fashion. This architecture is commonly used in applications where devices are located along a single path and there is a need for simple and reliable communication.
