How does the DNS solve the problem of translating domain names like example.com into IP addresses?
How does DNS help the Internet scale?
Answer:
DNS translates domain names and hostnames into IP addresses through a basic lookup function. When a user requests a domain name (as in the case of a browser lookup) the computer queries the local DNS server to find the matching IP address. If the local DNS server does not contain the information in it's local database, it contacts the next higher DNS system or the root domain DNS servers (i.e. microsoft.com - if the local system does not know it, it will query the well-known DNS server for the .com domain - which will know where to get the information).
DNS helps the users by not requiring them to remember the IP address of every system them want to connect with. microsoft.com is much easier to remember than 40.82.167.220.
DNS also helps the internet scale through the use of load balancing. Multiple systems can comprise a single web site with the web pages stored on many different machines with multiple IP addresses. When a user requests the microsoft.com website IP, they are given the primary IP of the load balancer sitting in front of the multiple computers. The load balancer will then distribute the traffic to any of the systems that are hosting the web page that are not busy. To the end user it look like they are connecting to a single machine - when in fact they are connecting to one of potentially hundreds of web servers with the same content. As traffic grows on the internet more servers are necessary to handle the additional traffic. DNS helps ensure the end user will connect to the proper web server regardless of the number of web server copies spun up in response to the additional traffic. This allows the capacity to scale as necessary without interruption to the web site.
Explanation:
DNS translates domain names into IP addresses so that the browsers can be able to load internet.
Through a lookup function, DNS solve the problem of translating domain names like example.com into IP addresses. It should be noted that when a user requests a domain name, the local DNS server will then find the matching IP address.If the information isn't contained in the local database, then the information will be requested from the next higher DNS system. Through the Domain Name System (DNS), the human readable domain are translated to machine readable IP addresses.Lastly, Domain Name System also helps in scaling the internet through the use of load balancing. The load balancer helps in the distribution of the traffic to the system hosting the web page.Read more on:

Assume that sum is called with a parameter that satisfies the precondition and that it executes without error. How many times is the test expression i < bound in the for loop header evaluated
The number of times which the test expression i < bound in the for loop header can be evaluated assuming that a sum is called with a parameter that satisfies the precondition and that it executes without error is:
As many times as needed until the condition is met but which must be at least 1 time.What is a Loop?This refers to the repetition of an iteration until a preset condition is met and then it stops.
Hence, when a sum is called with a parameter in a line of code and a for loop is used with the test expression i< so that a certain condition can be met, then there would be multiple iterations until that condition is met, until it stops, which is the code execution without an error.

What is snapshot?Data Snapshot captures and stores historical data from a report. It takes snapshots of data from a selected report on a regular basis and stores them in a table for historical report creation and analysis.
Snapshots are typically used for data protection, but they can also be used for application software testing and data mining.
When information is lost due to human error, a storage snapshot can be used for disaster recovery (DR).
A snapshot table contains the same raw, transactional data as its source in the transactional system, plus extra fields for tracking the snapshot date.
Snapshot tables are populated nightly with the rows of data in the source table that are considered effective (i.e., current) at the time of the extract.
Thus, the correct option is b.

Wanda is taking photos using a lens that sees and records a very narrow view with a focal length longer than 60mm. When her friend asks what type of lens she is using for their photography outing,
Answer:
a telephoto lensExplanation: It's on Quizlet lolAnd I got it correct on the test...
It provides an instant 2x optical zoom and has a focal length that is twice that of the primary lens. Additionally, it has a limited field of view, which causes distant things to resemble those that are nearby.
What role of telephoto lens in taking photos?Simply put, a telephoto lens deceives the eye into thinking a topic is closer than it actually is. This may be the best option for photographers who are physically unable to go close to their subjects or who are concerned for their safety.
With a telephoto lens, the background elements appear larger and nearer to the foreground elements. The converse is true with wide-angle lenses, which make background elements appear smaller and farther away from the camera.
Therefore, a telephoto lens Wanda uses a lens longer than 60 mm in focal length to capture images with a very small field of view. When her friend inquires about the lens she will be using on their photographic excursion.
