Correct answer: DuckDuckGo
DuckDuckGo is an internet search engine that prioritizes privacy and avoiding the filter bubble of personalized search results. It distinguishes itself from other search engines by not profiling its users and by displaying the same search results to all users for a given search term.
12. Which of the following protocols is a popular communication protocol used for network communication that divides any message into a series of packets?
Correct answer: Transmission Control Protocol
Transmission Control Protocol (TCP) is a popular communication protocol that is used for network communication. It divides any message into a series of packets that are sent from source to destination, where they are reassembled.
13. Composite Key is another name for _________.
Correct answer: Compound Keys
A Composite Key is a table column combination that can be used to uniquely identify each record. It is also referred to as a Compound Key.
14. CAPTCHA is a security measure that distinguishes humans from computers. What does the letter 'T' in CAPTCHA stand for?
Correct answer: Turing
CAPTCHA is a security measure that distinguishes humans from computers. CAPTCHA stands for Completely Automated Public Turing Test to Distinguish Between Computers and Humans. A CAPTCHA is frequently an image of text that has been distorted so that humans can read it but most automated computer vision systems cannot.
15. A blue screen of death (BSoD) is an error screen that appears on Windows computers after a fatal system error. What does the letter 'S' in BSoD stand for?
Correct answer: Screen
BSoD is an abbreviation for Blue Screen of Death.It is also referred to as Bluescreen or Bug Check. BSoD is an error screen that appears on Windows computers after a fatal system error. It denotes a system crash, which occurs when the operating system has reached a point where it can no longer operate safely. This can be caused by a variety of issues, such as a general hardware failure or a critical process terminating unexpectedly.
16. Which of the following refers to the set of rules in a programming language that defines the combinations of symbols that are considered to be correctly structured statements in that language?
Correct answer: Syntax
When referring to a programming language, syntax is a set of grammar and spelling rules. In other words, it refers to the use of character structures that a computer can understand. For example, if a user attempts to execute a command without the proper syntax, a syntax error is generated, causing the program to fail.
17. Choose one of the following as an example of Hardware:
Correct answer: I, II, III and IV
Computer hardware refers to the mechanical and electronic components of a computer. Without hardware, a computer cannot function properly. Monitor, case, keyboard, mouse, printer, CPU, RAM, and persistent storage, for example.
18. Who is considered as the Founder of the Modern Digital Computer?
Correct answer: Charles Babbage
The first analytical engine, or difference engine, was invented by Charles Babbage, a British mathematician at Cambridge University. This machine could be programmed using punch card instructions and had mechanical memory to store the results. Charles Babbage is known as the "Father of the Modern Digital Computer" for his contributions in this field.
19. Permanently installed software in electronic devices that controls the basic functions of hardware is referred to as _________.
Correct answer: Firmware
Firmware is software that is permanently installed in electronic devices and controls the basic hardware functions. A firmware example is BIOS.
20. Choose the input device that copies from paper into a computer from the list below.
Correct answer: Scanner
A scanner is a type of input device that scans documents such as photographs and text pages. When you scan a document, it is converted into a digital format.This results in the creation of an electronic version of the document that can be viewed and edited on a computer.

It is widely used in design and troubleshooting. LAN transmission rates range from 4Mbps to 16Mbps and can reach 100Mbps (Mbps stands for megabits per second).
24. In the case of a computer, we always use the term bandwidth to refer to something related to data. Which of the following is it referring to?
Correct answer: Amount of data transferred
In computing, bandwidth is defined as the bit rate of available or consumed information capacity, typically expressed in metric multiples of bits per second. Bandwidth is variously referred to as network bandwidth, data bandwidth, or digital bandwidth. In the field of signal processing, wireless communications, modern data transmission, digital communications, and electronics, bandwidth is used to refer to analog signal bandwidth measured in hertz, which means the frequency range between the lowest and highest attainable frequency while meeting a well-defined impairment level in signal power. The actual bit rate that can be achieved, however, is determined not only by the signal bandwidth, but also by the noise on the channel.
