Client server networks can be best explained as:*1 pointBackup and recovery possibleCentralizationProper managementAll the above

To determine the best explanation for client-server networks, let’s analyze the provided options:

1. Backup and recovery possible: Client-server networks typically allow for more effective data management, including backup and recovery, because data is centralized.

2. Centralization: One of the key characteristics of client-server architecture is that data storage and management are centralized on the server, making it easier to manage and secure.

3. Proper management: Centralization also aids in proper management of resources, user access, and security protocols. Administrators can efficiently allocate resources and maintain control over the network.

4. All the above: This option suggests that all the previously mentioned points contribute to the understanding of client-server networks.

Analysis

All the options discussed are valid aspects of client-server networks. Centralization is a fundamental feature of these networks, and it inherently supports backup/recovery processes and proper management of resources.

Given that each component contributes significantly to the overall benefits of client-server architecture, the most comprehensive answer is "All the above".

Final Answer

All the above.
