Question 1

What printer is commonly used to produce high-quality professional drawings such as architectural blueprints?

Accepted Answer

A plotter is commonly used to produce high-quality professional drawings such as architectural blueprints. They are specifically designed for large format printing and can handle high-resolution images and graphics. Ink-jet and laser printers may not have the necessary size and resolution capabilities for these types of prints, and mobile printers are not suitable for large-scale printing projects.

Question 2

Alex needs to email his graduation certificate to a prospective employer.He has only physical copies of the certificate.What device could he use to create an electronic copy of the certificate?

Accepted Answer

Alex can use a scanner to create an electronic copy of his graduation certificate by scanning the physical copy and saving it as a digital file. A plotter is a device used for printing large format documents, not creating electronic copies. A digital pen is used for digital writing and drawing, not scanning documents. A projector is used for displaying images and presentations, not creating electronic copies.

Question 3

Which is the most suitable device to use in a classroom or a conference room to deliver presentations?

Accepted Answer

The most suitable device to use in a classroom or a conference room to deliver presentations is a projector. A projector can display the presentation on a large screen, making it easier for everyone in the room to see and follow along.

Question 4

What could cause an external drive, like a USB flash drive, to not be recognized when plugged into a computer?

Accepted Answer

The most likely reason for an external drive not being recognized is a faulty port. This could be due to physical damage or wear and tear on the port. It is also possible that the computer's drivers for the USB port are out of date or corrupted, preventing the drive from being detected. Dusty computer vents or a lack of space on the hard drive would not directly affect the ability to recognize an external drive, and issues with internet connectivity are unrelated to this problem.

Question 5

Peripheral devices, like a USB flash drive, are generally connected to your computer through ports.

Accepted Answer

This statement is true. Peripheral devices like USB flash drives, keyboards, and printers are connected to a computer through various ports such as USB, HDMI, or Ethernet.

Question 6

What determines the speed at which data travels?

Accepted Answer

The answer of What determines the speed at which data...

Question 7

Which of the following factors can affect processor performance of a CPU?

Accepted Answer

Clock speed is a measure of the number of instructions that a processor can execute per second. A higher clock speed generally correlates to better performance. Benchmark measures performance, but it's not a factor that affects performance itself. Hard drive space and the number of peripheral devices connected do not directly affect processor performance.

Question 8

All-in-one computers are easier to service and upgrade but occupy more space than desktop computers.

Accepted Answer

All-in-one computers integrate the CPU and monitor into one unit and are therefore more difficult to upgrade and repair. They also take up more space on a desk compared to traditional desktop computers.

Question 9

What devices do not need device drivers to be manually installed, and start to function as soon as they are connected to a computer?

Accepted Answer

Plug-and-play devices are designed to automatically recognize and configure with a computer once they are plugged in. This eliminates the need for manual installation of device drivers. Printers and video cards usually require specific drivers to be installed for proper functionality, and while monitors typically don't require drivers, they may require some configuration depending on the setup.

Question 10

Daniel wants to buy a computer to use for playing games after work.He loves racing games and wants to make sure his device has all the specifications needed to run them smoothly and efficiently.Which of these factors should he consider?

Accepted Answer

The processor core is the most important factor to consider when buying a computer for gaming, especially for racing games which require a lot of processing power. It is important to check the processor speed, cache, and number of cores to ensure that the device can handle the complex graphics and game mechanics. The other factors mentioned are not as crucial for gaming performance.

Question 11

Jack needs a convenient way to browse the Internet, read emails, and store basic data when he travels.Which of the following would be the best option for him?

Accepted Answer

A tablet is a portable and lightweight device that offers easy browsing and email access, as well as basic data storage. It is perfect for travel due to its small size and low weight. An all-in-one computer and desktop computer are not portable, while a high-end laptop can be bulky and heavy for travel.

Question 12

Which of the following is a game controller that is held with both hands and used to control movement of on-screen objects by pressing buttons and moving hardware components?

Accepted Answer

A gamepad is a type of game controller that is held with both hands and used to control movement of on-screen objects by pressing buttons and moving hardware components, such as thumbsticks or triggers. A joystick is a similar type of controller, but typically only has one control stick and fewer buttons. A digital pen and stylus are input devices used for handwriting and drawing on a digital surface, and are not typically used for gaming.

Question 13

Which type of a computer can be assembled using a monitor, a keyboard, a CPU, speakers, a printer and a mouse?

Accepted Answer

A desktop computer is the only option that fits the description of being assembled using separate components such as the monitor, keyboard, CPU, speakers, printer, and mouse. Laptops, all-in-one computers, and tablets are typically pre-built with these components integrated into one device.

Question 14

Rocco runs a software firm that creates database management systems for other businesses.How can he ensure that his employees' computers remain protected from viruses and other malware?

Accepted Answer

The best way to ensure protection from viruses and other malware is to have periodic anti-virus scanning and software upgrades on all computers. This will ensure that the computers are protected from the latest threats and vulnerabilities. Additional RAM, defragmentation, and cleaning of hardware components may improve performance and longevity of the computer, but they do not directly protect it from malware.

Question 15

A joystick is a pen-type input device used to draw and tap icons.

Accepted Answer

A joystick is a device typically used for gaming or controlling movement in software applications, not for drawing or tapping icons.

Question 16

What performance specification does 2 GHz refer to?

Accepted Answer

2 GHz refers to the speed at which the processor executes instructions. It measures the number of clock cycles per second that a processor can execute. A higher clock speed indicates that the processor can execute more instructions per second, thus increasing the overall speed of the computer.

Question 17

What device do e-learning applications usually use to help users with visual impairment read digital content?

Accepted Answer

E-learning applications usually use voice synthesizers to help users with visual impairment read digital content. Voice synthesizers convert text into speech, allowing users with visual impairments to hear the content of the e-learning application.

Question 18

It is advised to fully charge the battery of a laptop before using it for the first time.

Accepted Answer

It is recommended to fully charge the battery of a laptop before using it for the first time as it ensures that the battery performs at optimal levels and lasts longer.

Question 19

When considering a computer to purchase, which of the following factors involves the operating system of the computer?
