What MIT-developed third party authentication protocol was named for a mythological beast?
Correct Answer
C. Kerberos
Explanation
Kerberos is a third-party authentication protocol developed by MIT and named after the mythological three-headed dog, Kerberos. Just like the dog guarded the gates of the underworld, the Kerberos protocol is designed to provide secure authentication for computer networks. It uses a trusted third party, known as the Key Distribution Center (KDC), to authenticate users and grant them access to network resources. This protocol uses tickets to verify the identity of users and ensure secure communication between clients and servers. Overall, Kerberos plays a crucial role in ensuring the security and integrity of network systems.

The year 2009 saw the unveiling of which "computational engine for the Web"?
Correct Answer
D. Wolfram AlpHa
Explanation
In 2009, Wolfram Alpha was unveiled as a "computational engine for the Web". It is a powerful search engine that provides answers to factual queries by computing them rather than just providing a list of links. It uses a vast amount of curated data and algorithms to generate accurate and detailed responses to a wide range of questions. Wolfram Alpha has become a popular tool for students, researchers, and anyone seeking precise and reliable information.

PPTP allows what other protocol to be tunneled through an IP network?
Correct Answer
A. PPP
Explanation
PPTP (Point-to-Point Tunneling Protocol) allows the PPP (Point-to-Point Protocol) to be tunneled through an IP network. PPP is a data link layer protocol used for establishing a direct connection between two nodes in a network. PPTP encapsulates PPP packets within IP packets, allowing them to be transmitted over IP networks such as the internet. This enables secure and private communication between two endpoints by creating a virtual private network (VPN) over the IP network.
6.
Software such as "Tomato" which is loaded onto wireless routers is classified by what name?
Correct Answer
B. Firmware
Explanation
Firmware refers to software that is permanently stored in a hardware device, such as a wireless router. It provides the necessary instructions for the device to function properly. In this case, "Tomato" is a type of firmware that can be loaded onto wireless routers, enhancing their capabilities and features. Therefore, the correct answer is Firmware.
7.
Thin-film transistor arrays on special plastics allow for prototyping what displays?
Correct Answer
A. Flexible
Explanation
Thin-film transistor arrays on special plastics allow for prototyping flexible displays. These displays can be bent, curved, or rolled, making them ideal for applications where traditional rigid displays are not suitable. Flexible displays have various potential uses, including wearable technology, foldable smartphones, and curved televisions. The use of special plastics in combination with thin-film transistors enables the creation of these flexible displays.

What does the term "GNU" stand for?
Correct Answer
D. GNU's Not Unix
Explanation
The term "GNU" stands for "GNU's Not Unix." This acronym was created by Richard Stallman in the 1980s as part of the GNU Project, which aimed to develop a free and open-source operating system similar to Unix. The name was chosen to reflect the project's goal of creating a Unix-like system that was not proprietary or controlled by any specific company. The GNU Project eventually led to the development of the GNU operating system, which is commonly used in combination with the Linux kernel to create what is known as GNU/Linux.
