The two major types of DNS request are as follows;

  • Recursive Query
  • Iterative Query

<h3>What is a domain name system?</h3>

Domain name system is abbreviated as DNS.

A Domain Name System (DNS) converts domain names into IP addresses, which allow browsers to get to websites and other internet resources.

Basically,  DNS is a directory of names that match with numbers.

Computer uses IP addresses to communicate, therefore, the DNS convert domain names to IP address for communication.  

The two major types of DNS request are as follows;

  • Recursive Query - Query that demands a resolution
  • Iterative Query - Query that does not demand a resolution.

Answer:

  1. 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.
  2. 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.

What is the difference between throughput and bandwidth?
masha68 [24]

Answer: Please find below the answer along with explanation.

Explanation:

For  a given communication channel (for instance, a LAN segment using Ethernet ) the Bandwidth refers to the theoretical maximum data rate that the channel can support, for instance, 100 Mbps in a 100Base T network.

The throughput, instead, refers to the actual data rate achieved in a given communications channel, taking into account the different channel impairments.

For instance, in a LAN segment that uses the original Ethernet 802.3 standard (CSMA/CD), a frequent occurrence of collisions can take down the actual data rate from the theoretical 100 Mbps to a very lower figure, i.e., 5 Mbps.

Good information is characterized by certain properties. Explain how you understand these characteristtics of good information.
Sedbober [7]

Answer:

here is your ans

Explanation:

Characteristics of good quality information can be defined as an acronym ACCURATE. These characteristics are interrelated; focus on one automatically leads to focus on other.

Accurate

Information should be fair and free from bias. It should not have any arithmetical and grammatical errors. Information comes directly or in written form likely to be more reliable than it comes from indirectly (from hands to hands) or verbally which can be later retracted.

Complete

Accuracy of information is just not enough. It should also be complete which means facts and figures should not be missing or concealed. Telling the truth but not wholly is of no use.

Cost-beneficial

Information should be analysed for its benefits against the cost of obtaining it. It business context, it is not worthwhile to spend money on information that even cannot recover its costs leading to loss each time that information is obtained. In other contexts, such as hospitals it would be useful to get information even it has no financial benefits due to the nature of the business and expectations of society from it.

User-targeted

Information should be communicated in the style, format, detail and complexity which address the needs of users of the information. Example senior managers need brief reports which enable them to understand the position and performance of the business at a glance, while operational managers need detailed information which enable them to make day to day decisions.

Relevant

Information should be communicated to the right person. It means person which has some control over decisions expected to come out from obtaining the information.

Authoritative

Information should come from reliable source. It depends on qualifications and experience and past performance of the person communicating the information.

Timely

Information should be communicated in time so that receiver of the information has enough time to decide appropriate actions based on the information received. Information which communicates details of the past events earlier in time is of less importance than recently issued information like newspapers. What is timely information depends on situation to situation. Selection of appropriate channel of communication is key skill to achieve.

Easy to Use

Information should be understandable to the users. Style, sentence structure and jargons should be used keeping the receiver in mind. If report is targeted to new-comer in the field, then it should explain technical jargons used in the report.
