Recursive Query - When a DNS Client submits a Query to a DNS Server for name resolution. The response to the DNS Query might be either an answer to the query or an error message. In Recursive Query, if the DNS Server does not have the reply to offer an exact response to the DNS Client, the DNS Server may query other DNS Servers on behalf of the DNS Client.Iterative Query - When a DNS Client requests name resolution from the DNS server, the DNS Server returns the best reply it has. If the DNS Server does not recognize the response to the Client's DNS Query, the answer might also be a referral to another lower level DNS Server. This lower level DNS Server is designated by the higher level DNS Server as the Authoritative DNS Server for the DNS namespace with which the DNS Query is associated. Once the DNS Client receives the referral from the higher level DNS server, it may send a DNS query to the lower level DNS server that received the recommendation.The two major types of DNS request are as follows;

Phases of systems development life cycle do developers identify the particular features nd functions of a new system
Answer:
requirement analysis
Explanation:
The goal of the requirement analysis phase is to specify the system inputs, processes, outputs, and interactions in greater depth. The system's operations would be specified at the functional level by the end of this phase, which means that the functions and features to be done will be defined but not necessarily how they will be executed. Requirements Analysis should not evaluate computer software, documents, or data streams unless expressly restricted by the Project Charter. The risks associated with how the system will be integrated into the standard operating procedures will be identified and considered during the requirements analysis. The functional and system requirements of the business process, as well as the user and operational needs, will be collected throughout the requirements analysis.
The phase where developers identify the particular features and functions of a new system is the requirement and analysis stage.
What is system development?System development is the process of defining, designing, testing, and implementing a new software application or program.
