Do You Actually Know Computers?

The term "White Hat" is derived from the concept of cowboys wearing white hats to symbolize their virtuous and lawful intentions. In the context of cybersecurity, "White Hat" refers to individuals who search for security flaws in order to fix them and improve the overall security of a system or network. They are ethical hackers or security professionals who use their skills for defensive purposes, unlike "Black Hat" hackers who exploit vulnerabilities for malicious activities.

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.

The purpose of "interrupt 10H" is to handle video operations from the BIOS to the software. This interrupt allows the software to communicate with the video hardware and perform tasks such as displaying characters, changing screen modes, and manipulating pixels on the screen. It provides a standardized interface for video operations, making it easier for software developers to write programs that interact with the video hardware.

A VoIP Gateway is a device that interfaces between an IP network and the public telephone network. It allows voice communication to be transmitted over the internet protocol (IP) network, converting analog voice signals into digital data packets that can be transmitted over the IP network. This enables users to make phone calls using internet connection instead of traditional telephone lines.

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 Intel 80486 was the world's first microprocessor to contain over one million transistors on a .4 x .6 silicon chip. This advancement in transistor density allowed for greater processing power and performance in computers. The Intel Pentium, Motorola 6800, and Intel 80386 did not have the same level of transistor density as the Intel 80486.

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.

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.

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.

The Intel 80486 chipset first came out in 1989.

The correct answer is E10k. In the year 1999, Sun Microsystems' largest and most powerful server was the E10k.

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.

IBM's first product was the counting machine, also known as the tabulating machine. This machine was developed by IBM's predecessor, the Tabulating Machine Company, and was used to process and tabulate data by mechanical means. The counting machine played a significant role in revolutionizing data processing and laid the foundation for IBM's future success in the computing industry.

The correct answer is 701. The IBM 701, also known as the Defense Calculator, was the first computer manufactured by IBM. It was introduced in 1952 and was designed for scientific calculations. The 701 was a vacuum tube-based computer that could perform complex calculations at a faster speed compared to other computers of that time. It marked a significant milestone in the development of computing technology and set the foundation for future advancements in the field.

In 1992, the first commercial short text message was sent. This implies that before 1992, short text messages were not commercially available.
