Answer:
D. A DNS server asks another DNS server to resolve a domain name
Explanation:
DNS (Domain name system) queries are essentially of two types;
i. recursive address resolution
ii. iterative or non-recursive address resolution
=> In the <em>recursive address resolution</em>, which represents a recursive query, when a DNS server A, receives a request from a client and does not know how to resolve such request, the DNS server sends the query to another DNS server B on behalf of this client. DNS server B can either reply to the query with the actual answer or an error message. If it's an actual answer, it returns to the client. Otherwise, it queries another DNS server, say C.
=> In the <em>iterative address resolution</em>, once the DNS server A receives a request from the client, it tries to reply the client with the best answer it can give. If the DNS server A does not have an answer, it refers the client to another DNS server say B. In this case, the server A does not directly query the server B. Instead, it refers the client to the server B.
Answer:
Go into short-term memory
Explanation:
Data stored on physical storage devices must go into short-term memory before the processor can access it.
This is because, physical storage devices are secondary memory which store information for a long time. The CPU does not work directly with secondary memory but with primary or short term memory. Since the CPU works mainly with short term memory, information in physical storage or secondary memory has to go into short term memory for the CPU to be able to process it.
<u>So, data stored on physical storage devices must go into short-term memory before the processor can access it.</u>
Answer:
The answer is "failing to keep a proper lookout".
Explanation:
The theory of collision, especially concerning gas were used to forecast the chemical reaction. It is based on the idea which atoms or molecules of interacting organisms should be mixed or collided. In this question the key cause of collision would be a proper viewpoint is not established, that's why other given choices were wrong.

<h3>What is a
mobile computing device?</h3>
Any device that was built using mobile parts, such as mobile hardware and software, is referred to as a mobile computing device. Portable devices that can function like a typical computing device in terms of operation, execution, and provision of services and applications are known as mobile computing devices.
Portable and handheld computing devices are other names for mobile computing devices.
Modern handheld devices that have the hardware and software needed to run common desktop and Web applications are generally referred to as mobile computing devices. Similar hardware and software elements found in personal computers, such as processors, random memory and storage, Wi-Fi, and an operating system, are also found in mobile computing devices. They are made specifically for mobile architecture and portability, which sets them apart from PCS.
