The correct answer is B. Primary DNS Server.

DNS records are type of data that is equivalent to IP address where the website or domain is located.  DNS records are normally stored in DNS server in a raw or flat file. A host, using port number 53 will send a DNS request to the server. If the computer has stored it's data or record in it's database, it will automatically reply to the requesting host. Example: You typed in www.website.com, if you have a matching DNS record in your server, using an IP address, your server will reply and display the website.

garri49 [273]

The term used to describe whereby old and new media are available via the integration of personal computers and high speed satellite based phone or cable links is: media convergence.

<h3>What's a good illustration of media convergence? </h3>
  • Smartphones, laptops, and ipads are the finest instances of media convergence since they combine several forms of digital media, including radio, cameras, TVs, music, and more, into a single, straightforward gadget.
  • The blending of formerly separate media platforms and technologies through digitization and computer networking is referred to as media convergence. Another name for this is technical convergence.
  • Media ownership concentration, sometimes referred to as media consolidation or media convergence, is the process through which a smaller number of people or organisations come to control a larger portion of the mainstream media.
  • According to recent study, there is a rising amount of consolidation in the media sectors, which are already highly concentrated and controlled by a very limited number of companies.

To learn more about media convergence, refer to the following link:

he timing device in an automobile’s intermittent wiper system is based on an RC time constant and utilizes a 0.500-μF capacitor
Tatiana [17]

Answer:

4000k-ohm to 10,000k-ohm

Explanation:

As we know that time constant for an RC circuit is t=RC

Putting the values of t we can get the range of varaiable resistor as;

t=RC

Putting t=2 we get the first value of the range for the variable resistor

2=R*0.500*10^-6

R=2/(0.500*10^-6)

R=4*10^6

R=4000k-ohm

Now putting t=5 we get the final value for the range of variable resistor

t=RC

5=R*0.500*10^-6

R=5/(0.500*10^-6)

R=10*10^6

R=10,000k-ohm

So variable resistance must be made to vary in the range from 4000k-ohm to 10,000k-ohm

Five programs are currently being run in a computer. Program 1 is using 10 GiB of RAM, program 2 is using 5 GiB of RAM, program
muminat

Virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost because it is one that tend to allows the system to give all of the process its own memory space that is said to be  isolated from the other processes.

<h3>How is virtual memory used instead of RAM?</h3>

A system is known to make use of a virtual memory and this is one that tend to make use of a section of the hard drive to act like the RAM.

With the use of virtual memory, a system can be able to load bigger or a lot of programs running at the same time, and this is one that tends to hep one to work as if it has more space, without having to buy more RAM.

Therefore, Virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost because it is one that tend to allows the system to give all of the process its own memory space that is said to be  isolated from the other processes.
