An example of leapfrogging can be seen in developing countries where land-line telephones have been skipped, and citizens are using cellular phones. Option C.
Leapfrogging refers to a phenomenon where developing countries adopt newer technologies without going through the intermediate stages or older technologies that more developed countries experienced. It involves bypassing traditional infrastructure or outdated systems to embrace more advanced solutions directly.
In the given example, the use of cellular phones in developing countries without a widespread presence of land-line telephones illustrates leapfrogging. These countries often faced challenges in establishing a comprehensive land-line network due to various factors such as limited resources, geographic constraints, and infrastructure limitations.
As a result, they were able to leapfrog the traditional land-line telephone infrastructure and directly adopt cellular technology.
Cellular phones provide a flexible and cost-effective communication solution, particularly in regions where establishing land-line infrastructure may be difficult or economically impractical.
The availability and affordability of mobile devices have made it possible for people in developing countries to access communication services without relying on land-line networks.
Leapfrogging allows developing countries to rapidly bridge the digital divide by enabling access to modern communication technologies. It brings several benefits such as improved connectivity, access to information, and opportunities for social and economic development.
Mobile phones provide a means of communication, access to the internet, mobile banking, and various other services that contribute to social inclusion and economic growth.
However, it's important to note that leapfrogging also poses challenges, such as ensuring widespread network coverage, addressing affordability issues, and promoting digital literacy among populations that may be new to these technologies.
Additionally, it may result in a new form of digital divide, as access to advanced technologies can still be limited in certain regions or among specific demographics within developing countries.
Overall, leapfrogging represents an innovative approach to technology adoption, enabling developing countries to embrace the benefits of advanced technologies and accelerate their progress without going through traditional developmental stages. So Option C is correct.

Which of the following is frequently limited in terms of experience and theatrical background? A) reviewer. B) critic. C) both reviewer and critic
Reviewers are frequently limited in terms of experience and theatrical background compared to critics, who typically have more expertise in the field. Thus, the correct option is :
(A) reviewer
Reviewers are frequently limited in terms of experience and theatrical background compared to critics. Reviewers often provide their opinions and impressions of various artistic performances, including theater productions, in a more casual and subjective manner. They may not have formal training or extensive experience in the field of theater.
On the other hand, critics typically possess a deeper understanding of the art form, often with a background in theater, and are well-versed in its history, techniques, and conventions. Critics are more likely to have received formal education or training in theater and may have practical experience as actors, directors, or playwrights. They often analyze and evaluate theatrical productions from a more objective and critical standpoint, considering elements such as acting, directing, stage design, and overall artistic merit.
While there can be overlap between reviewers and critics, the term "critic" typically implies a higher level of expertise and knowledge in the field of theater. Reviewers, on the other hand, tend to offer their personal reactions and opinions, but may not have the same level of depth or understanding of the art form.

C. Both on-site and off-site is can be used for storing backups. Storing backups both on-site and off-site is considered a best practice for data backup and disaster recovery.
Storing backups both on-site and off-site is considered a best practice for data backup and disaster recovery. On-site backup involves storing backup copies of data on the same location or premises as the original data. This allows for quick and easy access to the backup data in case of an emergency. Examples of on-site backup include storing backup copies on a local hard drive, tape drive or an on-premises backup server. Off-site backup, on the other hand, involves storing backup copies of data at a separate location, such as a remote data center or cloud-based service. This ensures that the backup data is protected from physical disasters that may occur at the primary location.

Which protocol is exploited by cybercriminals who create malicious iFrames?
a. DHCP
b. DNS
c. HTTP
d. ARP
The protocol that is exploited by cybercriminals who create malicious Frames is c. HTTP. HTTP (Hypertext Transfer Protocol) is the protocol used by web browsers to communicate with web servers. It is the foundation of data communication on the internet and is used to transfer data between the browser and the server.
Frames are used to embed content from another website within a web page, such as a video or advertisement. However, cybercriminals can use malicious Frames to inject malware or redirect users to a malicious website without their knowledge or consent. They do this by exploiting vulnerabilities in the HTTP protocol, which allows them to manipulate the content of the web page and trick the user into clicking on a link or downloading a file that contains malware. Therefore, it is important for users to be aware of the risks associated with malicious i Frames and to take precautions such as keeping their software up-to-date and avoiding suspicious websites and links. I'm happy to help with your question! The protocol exploited by cybercriminals who create malicious Frames is "c. HTTP". Here's a step-by-step explanation:
Cybercriminals create an Frame, which is an HTML element used to embed content from another source, such as a webpage or a video. They then insert malicious code into the iFrame, which can be designed to compromise the user's system or collect sensitive data. The iFrame uses the HTTP (Hypertext Transfer Protocol) to communicate with the target website and load the content. When a user visits the website containing the malicious iFrame, the HTTP protocol is exploited to execute the malicious code, potentially causing harm to the user's system or stealing their information.In summary, the ANSWER to your question is c. HTTP, as this is the protocol exploited by cybercriminals when creating malicious Frames.The protocol that is exploited by cybercriminals who create malicious Frames is c. HTTP. HTTP (Hypertext Transfer Protocol) is the protocol used by web browsers to communicate with web servers.

new 3d printers draw on the surface of liquid plastic quizlet
This statement is partially true.
The technology being referred to is likely the DLP (Digital Light Processing) 3D printing method, which uses a projector to solidify liquid resin.
However, the resin is not necessarily "plastic," as resins can be made from a variety of materials, including photopolymers, epoxies, and even ceramics.
The projector shines UV light onto a surface coated in a liquid resin, causing it to solidify layer by layer until the object is complete. This method can produce very high-resolution prints with fine details, but it may not be suitable for all types of 3D printing applications due to the limited range of materials available.
