What color model should Joe use if he will be using an offset printing press?

A. RGB

B. hexadecimal

C. CMYK

D. index

Answers

Answer:

CMYK

Explanation:

Monitors typically use RGB color (additive model — adding to make white), but offset printing uses CMYK pigments (subtractive color — subtracting from the existing white). Printed images have less visual range, saturation, and contrast than digital images, so in print, colors will usually appear darker and less vibrant.

Answer:

The option that one should look for in Hyper-V is snapshot. The correct option is b.

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.

How does the DNS solve the problem of translating domain names like example.com into IP addresses?

How does DNS help the Internet scale?

Answers

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.

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

Answers

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.
