Understanding the characteristics of networks

• Security in networks refers to measures implemented to protect data and network infrastructure from unauthorized access and threats
• Integrity in networks ensures that data remains accurate and consistent during storage, transmission, and processing
• Reliability in a network refers to its ability to perform consistently without failures.


  True
• What are network characteristics used for in evaluating a network's suitability?

  Specific purposes
• What is a key disadvantage of vertical scalability?

  Higher downtime for upgrades
• Scalability refers to the ability of a network to handle increasing workloads or users without experiencing performance degradation
• Security in networks involves preventing unauthorized access to data and network resources
• Redundancy in networks ensures minimal downtime during failures.


  True
• What does bandwidth in a network affect?

  Data transfer speed
• Match the network characteristic with its definition:

  Bandwidth ↔️ Data transmitted per unit time

  Reliability ↔️ Consistent performance without failures

  Scalability ↔️ Ability to handle increasing loads

  Security ↔️ Protection from unauthorized access
• Network characteristics are essential for evaluating a network's suitability for specific purposes.


  True
• Horizontal scalability involves adding more machines to distribute the workload.
• Hashing is a key measure to ensure data integrity.


  True
• Arrange the strategies to improve network reliability in the order of their implementation:
